Can’t Find a Blockage But Washing Machine Still Not Draining
A washing machine pump that runs but fails to drain has a different range of causes from a pump that does not run at all. The most likely explanations are a hidden blockage in the pump outlet chamber or drain hose, a broken impeller inside the pump, a kinked sump hose from a dropped drum, or a blanking piece left in new plumbing. Work through each cause systematically before concluding the pump itself needs replacing.
The pump is definitely running, you can hear or see it operating, and you have already checked the pump filter and pump area for blockages and found nothing. If you have not yet worked through the main drain fault guide, start there first: washing machine won’t drain water.
A pump that runs but fails to move water is a specific and frustrating fault. Once obvious blockages have been ruled out, there are several less visible causes worth investigating before concluding the pump itself has failed.
Cause 1: There Is Still a Blockage – Just a Hidden One
Small objects that pass through the pump filter can still cause significant obstruction inside the pump. The most common culprits are elastic bands, hair bobble elastic, fragments of bra wire, buttons, small screws, or pieces of grit. These can wedge underneath the impeller, wrap around it, or lodge inside the pump outlet chamber where the drain hose connects – completely out of sight through the filter access point.
How to Check the Impeller
With the machine unplugged, try turning the pump impeller by hand using a finger or screwdriver. It should rotate freely. Some impellers naturally have a small magnetic resistance that causes them to jump 180 degrees when overcome – this is normal. What is not normal is an impeller that is tight or stiff throughout its full rotation, which suggests an obstruction restricting its movement.
The Pump Outlet Chamber
A button of a specific size can be small enough to pass through the pump filter and even past the impeller, but large enough to jam inside the outlet chamber where the drain hose attaches. This obstruction is invisible without removing the drain hose and looking directly into the outlet. A piece of bra wire can do the same – getting through the impeller but catching in the chamber, where it then snags passing fluff and threads until a solid blockage builds up.
To check: remove the drain hose from the pump outlet and inspect the chamber with a torch. Look for any small object, wire fragment, or compacted debris lodged inside.
Cause 2: Blockage in the Drain Hose or U-Bend Connection
An object that passes through the pump can still cause a complete blockage further along the drain hose or at the point where the hose connects to the U-bend under the sink.
A button of the right size can travel into the drain hose but be too large to pass through the plastic spigot on the U-bend. In some cases the button sits in the flow and acts as a butterfly valve – swivelling one way to allow water through, then swivelling back under the water pressure to close off the flow again. This can produce an intermittent fault where the machine sometimes drains and sometimes does not.
How to Check the Drain Hose
-
Disconnect the drain hose from the U-bend connection under the sink and examine the end of the hose and the inside of the plastic spigot for any obstruction.
-
If necessary, disconnect the drain hose from the machine and check its full length. A blockage mid-hose can sometimes be felt by running a hand along the outside.
-
To clear a stubborn hose blockage, connect the open end of the drain hose to a cold tap and run water through from the opposite direction. Hold the connection firmly – the water pressure can be significant and the hose can pull free unexpectedly.
Cause 3: The Pump Itself Is Faulty
If no blockage can be found anywhere in the pump, outlet, or drain hose, the pump itself may have failed internally. The most likely internal failure is a broken impeller that has separated from the pump shaft. The rotor continues to spin, producing the sound of a running pump, but the impeller that actually moves the water is no longer attached or is slipping on the shaft. The pump may sound slightly different to normal in this situation, though not always noticeably so.
A less common failure mode is a pump that oscillates rather than rotates properly – causing it to vibrate but not generate the flow needed to pump water away. This is difficult to diagnose without removing and testing the pump directly. See our guide on washing machine pumps for more detail.
Cause 4: Kinked Sump Hose From a Dropped Drum
In some cases a fault elsewhere in the machine can cause the drum to drop slightly from its normal position. If the drum drops enough, it can compress or kink the sump hose – the main hose running from the base of the drum to the pump. A kinked sump hose restricts or completely blocks the flow of water to the pump, causing it to run without moving any water.
In cases matching this pattern – pump running, no blockage found, machine pumps a little water then stops – it is worth checking whether the drum is sitting in its correct position and whether the sump hose shows any sign of compression or kinking. The cause is typically a failed drum spring that normally holds the drum at the correct height.
Cause 5: New Plumbing Blanking Piece
If the machine stopped draining after being moved to a new property, or after new plumbing was installed, the problem may be a blanking piece left inside new pipework. New U-bends and sink waste fittings sometimes come with a factory-fitted blanking piece in the spigot that the drain hose connects to. This piece must be removed before the drain hose is connected – if it is left in place, no water can pass. See our guide on won’t drain after being moved for more detail.
Need a Qualified Engineer?
If all the above causes have been checked and the drain fault persists, a qualified engineer should inspect the pump and drainage system.

Frequently Asked Questions
Why is my washing machine pump running but not draining?
The most common causes are a hidden blockage in the pump outlet chamber or drain hose, a broken impeller inside the pump that is slipping on the shaft, a kinked sump hose caused by a dropped drum, or a blanking piece left in new plumbing. Work through each possibility systematically, starting with checking the pump outlet and drain hose for hidden obstructions.
How do I check if the pump impeller is blocked?
With the machine unplugged, try turning the impeller by hand through the pump filter opening using a finger or screwdriver. It should rotate freely. An impeller that is tight or stiff throughout its rotation is likely obstructed. Some magnetic resistance causing the impeller to jump 180 degrees is normal – consistent tightness around the full rotation is not.
Could a button cause a drain fault even though it passed through the filter?
Yes. A button can pass through the pump filter and even past the impeller, but jam in the pump outlet chamber where the drain hose connects. It can also travel into the drain hose and act as a butterfly valve in the U-bend connection, alternately allowing and blocking flow depending on its orientation. Both situations require removing the drain hose to inspect.
Could the pump sound normal but still be faulty?
Yes. If the impeller has separated from the pump shaft, the rotor continues to spin and the pump sounds like it is running normally. The impeller is not attached or is slipping, so water is not being moved. The sound may be slightly different to normal but is not always noticeably so. This type of internal failure requires the pump to be removed and inspected directly.
What is a sump hose and how can it cause a drain fault?
The sump hose is the main hose connecting the base of the drum to the pump. If the drum drops from its correct position – typically because a drum spring has failed – the sump hose can become kinked or compressed, blocking the flow of water to the pump. The pump runs normally but cannot draw any water. Checking for drum spring failure and sump hose kinking is part of the diagnosis when no blockage can be found.
Washing Machine Won’t Drain Water
A washing machine that won’t drain is almost always caused by a blockage somewhere in the drainage path, something jammed in the pump impeller, or pump failure. The first step is always to establish whether the pump is running or not – this determines which direction to investigate. Before starting, check whether the machine simply has a blown fuse or faulty wall socket, as this can cause a drain failure with no fault on the machine itself.
If the washing machine has only recently been installed or moved and now won’t drain, the cause is often simpler than a blockage or pump fault. See our guide on washing machine won’t drain after being moved or plumbed in before investigating further.
Step 1: Check the Basics First
If the machine has stopped mid-cycle with water inside and will not respond, check that the fuse has not blown and the wall socket is working correctly before investigating a drainage fault. A dead machine caused by a blown fuse or faulty socket looks identical to a machine with a drainage fault – but resolving the power issue gets the machine running again and pumps the water out without any further work.
Step 2: Drain the Water Manually
Before investigating the drain fault, as much water as possible needs to be removed from the machine. Attempting to access the pump filter or move the machine with a full drum is messy and risky.
See our full guide on how to manually drain water from a washing machine. Return here once the water has been drained to identify the cause.
Step 3: Establish Whether the Pump Is Running
This is the key diagnostic question. The answer determines which cause to investigate.
Pump IS running but not draining
If the pump can be heard running normally but water is not being cleared, suspect a blockage in the drainage path. The pump is working but cannot push water through. Investigate the pump filter, drain hose spigot, and U-bend connection.
Pump is NOT running
If the pump is not running, suspect a physical jam inside the pump impeller, a failed pump motor, or an electrical fault. Do not investigate blockages – a blocked filter cannot stop the pump from running or making noise.
Some Hotpoint, Whirlpool, and Indesit machines switch the pump off automatically when no water is detected inside the drum. If testing without water in the machine, this may be why the pump does not run – it is not necessarily a fault.
If the Pump Is Not Running
The most common reason a pump does not run is a physical obstruction jamming the impeller. With the machine unplugged and water drained, access the pump and check the impeller by hand:
-
The impeller should rotate fairly freely. It may have a slight magnetic resistance at one consistent point per revolution – this is normal. If it will not turn at all or is loose on the shaft, it is jammed or damaged. -
Listen when the machine attempts to drain. A humming sound instead of the normal pump noise suggests the pump motor is receiving power and is electrically functional but cannot rotate because it is physically jammed. -
If the impeller turns freely and the pump is not jammed, the pump motor needs electrical testing. A continuity test across the pump terminals checks for an open circuit winding – standard washing machine pump windings measure approximately 165 ohms. An open circuit reading confirms pump motor failure. This testing requires a multimeter and knowledge of safe electrical testing – if in doubt, book an engineer.
If the Pump Is Running – Check for Blockages
Work through the drainage path from the simplest and most accessible check to the most involved.
-
Check the drain hose spigot connection at the U-bend.
If the drain hose connects to a plastic spigot screwed into the U-bend under the sink, unscrew the spigot and inspect the opening. Small objects, accumulated lint, or threads can build up here and restrict flow enough to prevent drainage despite the pump running normally. This check requires no tools and does not require moving the machine.
-
Check and clean the pump filter.
Most washing machines have a pump filter accessible at the front base behind a panel or kickplate. Place towels on the floor and slowly unscrew the filter cap – water will escape as it opens. Remove the filter and check for blockages. A sock, large accumulation of lint, or similar object physically blocking the filter could account for the drainage failure. A few coins or buttons alone are unlikely to be the cause – only a substantial obstruction will stop drainage. See our guide on washing machine pump filter location and cleaning.
-
Inspect inside the pump chamber through the filter opening.
With the filter removed, shine a torch into the pump chamber where the impeller is visible. Objects such as coins, hairbands, hair grips, or bra underwires can get drawn through the filter and lodge against or inside the impeller. These make a loud grinding noise when the pump runs. Remove any objects found.
-
If no blockage is found at accessible points – consider an engineer.
If the pump is running, water is not draining, and no blockage is found in the filter, spigot, or U-bend, the blockage may be in a less accessible location – inside the sump hose, the pump chamber itself, or further along the drain hose. If water drained out easily when manually drained through the filter, this suggests no physical blockage in those routes. See our guide on no blockage but still not draining.
Two Variations of Drain Failure
There are two distinct patterns of drain failure with different implications:
| Pattern | Description | Most likely cause |
|---|---|---|
| No water pumped out at all | The drum remains completely full – not one drop has been cleared | Pump not running (jam, failure, or electrical fault), or complete blockage of the drainage path |
| Partial drainage only | Some water clears but a significant amount remains in the drum | Partial blockage somewhere in the drainage path, or an intermittent pump fault. Also consider whether another fault (such as an out-of-balance load preventing full spin) is responsible for residual water |
Testing pump motor windings requires working with electrical components. Ensure the machine is unplugged before accessing any internal components. If unsure about any step in this diagnosis, book a qualified engineer rather than risk electric shock. See our guide on DIY appliance repair safety.

Frequently Asked Questions
Why won’t my washing machine drain?
The most common causes are a blockage in the pump filter, drain hose spigot, or U-bend connection; something physically jammed in the pump impeller; or pump motor failure. The first diagnostic step is to establish whether the pump is running or not – this determines which cause to investigate. If the pump is running normally but not clearing water, suspect a blockage. If the pump is not running, suspect a jam or motor failure.
How do I know if the pump is running?
Listen carefully when the machine should be draining. A working pump produces a consistent humming or whirring sound that is clearly audible. If no sound is coming from the pump position (usually bottom-front of the machine), the pump is not running. A humming sound without the normal noise could indicate the pump motor is receiving power but the impeller is physically jammed.
Can I fix a blocked pump filter myself?
Yes – cleaning the pump filter is a routine maintenance task. Place towels on the floor, locate the filter access panel at the front base of the machine, slowly unscrew the filter cap to allow residual water to drain out, then remove and clean the filter. Refit securely before running the machine. See our pump filter guide for specific instructions by machine type.
Washing machine won’t drain after being moved
A washing machine that stops draining immediately after being moved or connected to new plumbing has three likely causes: a blanking piece left inside the U-bend connector, an obstruction dislodged inside the machine during transit, or a wiring or physical connection disturbed during the move. The blanking piece is by far the most common cause in newly built properties.
If your washing machine pumped out perfectly at your previous address but will not drain after being connected at a new property – or after being plumbed into a U-bend for the first time – this guide covers the most likely causes and how to check each one.
The Three Most Common Causes
-
A blanking piece left inside the U-bend drain connector. Common in new-build properties and occasionally in older ones where the previous occupant replaced the cap. The blanking piece blocks all water flow regardless of how well the machine is working. -
An obstruction dislodged inside the machine during transit. A coin, bra wire, nail, or screw sitting in the base of the drum or sump hose can be shaken loose during a move and find its way into the pump, jamming the impeller. -
A wiring connection or physical component disturbed during the move. The electrical connector to the pump can work loose during transit, or damage can occur to the pump or its connections.
Cause 1: The Blanking Piece
This is by far the most important cause to check first, because it is entirely external to the machine – the machine itself may be in perfect working order.
The drain hose from the washing machine connects to a plastic spigot fitting screwed onto the U-bend under the kitchen sink. In a newly built property, or one where no washing machine has been installed before, this spigot will have been fitted with a blanking cap to prevent sink water flooding into the under-sink cupboard. Until this cap is removed, no water can pass through from the machine into the drain.
In a property that has had a washing machine before, the previous occupant may have replaced the blanking cap when they left – to prevent the open spigot draining the sink into the cupboard. This is less common but worth checking.
How to Check and Remove the Blanking Piece
-
Disconnect the washing machine drain hose from the spigot on the U-bend.
-
Unscrew the spigot connector from the U-bend.
-
Look inside the connector at the tapered end where the drain hose attaches, and at the base where it connects to the U-bend. A blanking cap may be fitted at either point.
-
Also check inside the U-bend aperture itself for any obstruction or cap.
-
Remove the blanking piece if present. On some connectors, the tapered end of the spigot itself may need to be cut away to open the flow path – the spigot is designed to be cut or punched open on first use.
-
Reattach the connector and drain hose securely, then test the machine on a drain cycle.
Cause 2: Obstruction Dislodged During Transit
Objects that have been sitting harmlessly in the base of the drum or sump hose for months – coins, bra wires, nails, screws, or small items of clothing – can be shaken loose during a move and travel into the pump, jamming the impeller. The machine may have drained perfectly before the move and fail to drain immediately after reconnection because the obstruction only entered the pump during transit.
Check the pump filter first, then inspect the impeller for obstructions. For step-by-step guidance see our guides on the washing machine pump filter and washing machine pump troubleshooting.
Cause 3: Connection or Wiring Disturbed During the Move
The electrical connector to the drain pump can vibrate loose during transit. With the machine unplugged, check that all wiring connectors to the pump are firmly seated and undamaged. Also check whether the pump itself or the sump hose has been physically displaced or kinked during the move.
If the machine was moved without transit bolts fitted, the drum may have moved during transit in ways that damaged internal connections or pinched hoses. See our guide on transporting a washing machine safely for more on transit bolt requirements.
Still Not Draining After Checking All Three?
If the blanking piece, pump filter, and wiring connections have all been checked and the machine still will not drain, a qualified engineer should investigate.

Frequently Asked Questions
Why won’t my washing machine drain after moving to a new house?
The most common cause in a new-build or freshly plumbed property is a blanking piece left inside the U-bend drain connector. This blocks all water flow from the machine into the drain. Check the spigot fitting on the U-bend under the kitchen sink and remove any blanking cap before testing the machine again.
What is the blanking piece and where do I find it?
The blanking piece is a cap or plug fitted inside the plastic spigot connector on the U-bend under the sink. It is fitted in new properties to prevent sink water draining into the cupboard before a washing machine is connected. Unscrew the spigot from the U-bend and look inside both the tapered end and the base of the connector for a cap or internal obstruction.
Could the move itself have caused the drain fault?
Yes. Objects sitting in the base of the drum or sump hose can be dislodged during transit and jam the pump impeller. Wiring connections to the pump can also vibrate loose. If the blanking piece is not the cause, check the pump filter for obstructions and confirm all wiring connectors to the pump are firmly seated.
The drain hose is connected but water still fills without draining – is that the blanking piece?
Possibly – but if water is actively filling and draining simultaneously rather than simply failing to pump out, this is more likely to be a siphoning fault caused by the drain hose position. See our guide on washing machine filling and draining at the same time.
Belt Keeps Coming Off Washing Machine
The most common causes of a washing machine belt repeatedly coming off are a worn or stretched belt, a loose or worn drum pulley, or a loose motor. Inspect the belt and drum pulley first. If the drum pulley bolt uses Loctite threadlocker, always reapply it when refitting. If the drum has noticeable up-and-down movement at the door seal, the bearings may have failed.
Always disconnect the washing machine from the mains electricity supply before removing any panels or accessing internal components. Never work on a machine that is plugged in. Wait for the drum to stop completely before reaching inside.
If your washing machine belt keeps coming off, there is an underlying fault causing it. A belt that slips off once and stays on when refitted may have been dislodged by an unusually heavy or unbalanced load. A belt that comes off repeatedly means something is wrong with the belt itself, the pulleys, the motor fixings, or the drum bearings. This guide works through all seven causes in order of how commonly they occur.
How to Confirm It Is a Belt Problem
Before working through the causes below, it helps to confirm that the belt is actually the issue rather than a different fault causing the drum not to turn.
-
Motor running but drum not moving. With the machine running, you can hear the motor spinning normally but the drum is not rotating. This is the classic symptom of a detached or broken belt. -
Drum spins unusually freely by hand. With the machine unplugged, spin the drum by hand. A drum with a correctly fitted belt has clear resistance from the motor. A drum whose belt has come off spins with very little resistance at all. -
You can see the belt inside. On most machines, removing the back panel reveals the belt, motor, and drum pulley. A detached belt will be sitting loose at the bottom of the machine rather than running around both pulleys.
The 7 Causes of a Belt That Keeps Coming Off
Cause 1: Worn or stretched belt
The most common cause. Drive belts wear and stretch over time, eventually becoming too loose to stay on the pulleys during the high-speed spin cycle. A worn belt may also have fraying around the edges or visible cracking on the inner surface. On multi-groove V-ribbed belts, check that the grooves are still clearly defined and not worn smooth, and that there is no rubber debris in the grooves.
A correctly tensioned belt should give a firm, resonant “ping” when plucked, similar to a guitar string. There should be a small amount of sideways movement when pressed, roughly 6mm either side, but the belt should not feel loose or floppy. If the belt is slack or visibly worn, replacement is the correct fix. A belt that has simply come off once on an unusually unbalanced load, but shows no wear, can often be refitted and will stay on.
Cause 2: Loose drum pulley bolt
The drum pulley is the large wheel at the back of the drum that the belt runs around. It is bolted to the drum shaft and must be firmly fixed. If the pulley bolt has worked loose, the pulley wobbles as it rotates during spin, causing the belt to ride off the pulley edge. This is a common cause on machines that have been previously repaired without Loctite threadlocker being applied to the bolt.
To check: with the back panel removed, grip the drum pulley and try to rock it from side to side. There should be no noticeable play. If it rocks even slightly, the bolt is loose. Tighten the bolt firmly, but do not overtighten it. If the bolt shears off in the drum shaft, the drum shaft or complete drum assembly may need replacing, which is an expensive repair. Always apply fresh Loctite threadlocker to the bolt before refitting.
Cause 3: Worn drum pulley
Even with the pulley bolt tightened correctly, a worn pulley can still cause the belt to come off. The pulley fits over the drum spider, a metal hub on the drum shaft, and over time this fit can wear loose. You can check this by removing the pulley bolt and rocking the pulley side to side on the shaft. If there is visible movement with the bolt removed, the pulley itself is worn and needs replacing, as no amount of bolt tightening will keep it running true.
Drum pulleys are available for most mainstream washing machine brands. You will need your exact model number to order the correct one. See our spare parts guide for sourcing.
Cause 4: Loose or damaged motor fixings
The motor must be rigidly fixed to the outer tub for the belt to run true. If one or more motor bolts have worked loose, or if a motor bolt has come out entirely, the motor will move slightly during spin, changing the distance between the motor pulley and the drum pulley and causing the belt to slip off. Check all motor mounting bolts are present and firmly tightened.
Cause 5: Cracked motor mounting arm
The motor is attached to the outer tub via cast alloy mounting arms or brackets. These can develop hairline cracks that are not immediately obvious but allow the motor to flex slightly during the spin cycle, even when the bolts are tight. A cracked mounting arm can cause the belt to come off intermittently, making the fault harder to find. Inspect each arm carefully under good light, checking particularly around bolt holes and any areas of previous repair. Read our guide: motor bracket on the drum is broken.
Cause 6: Broken drum bracket on the outer tub
On some machines, the motor is mounted to a bracket that is welded or bolted to the outer tub itself. If this bracket cracks or breaks, the motor is no longer held securely and will move during spin. This is less common than the other causes but worth checking on machines where no other cause can be found. Check the mounting bracket on the outer drum for cracks, particularly if the machine has been moved recently or had a previous heavy impact.
Cause 7: Failed drum bearings
Worn or collapsed drum bearings allow the drum to move up and down on its shaft. This movement causes the drum pulley to run out of true, deflecting the belt off the pulley during spin. To check for bearing wear, grip the drum near the door seal and try to lift it upward. A small amount of movement is normal. Significant up-and-down play, more than a few millimetres of visible movement, indicates bearing wear or collapse.
Failed bearings should also have produced a rumbling or grinding noise on spin for some time before the belt fault developed. If the machine has been increasingly noisy for several months and is now throwing the belt, bearing failure is very likely the cause. Read: what do worn drum bearings sound like?
Drum bearing replacement is a major repair involving full drum disassembly. On most budget machines, and on any machine over 6 to 7 years old, the repair cost typically approaches or exceeds the cost of replacement. If bearings have collapsed and seized onto the drum shaft, replacement is almost always the better outcome financially. Get a quote before authorising any work.
Preventing the Drum Pulley Bolt Coming Loose Again
A drum pulley bolt that keeps working loose is one of the most frustrating repeat faults on a washing machine. There are three methods manufacturers use to prevent this, and understanding which applies to your machine is essential before refitting.
Loctite threadlockerThe most common method. A blue, glue-like substance is applied to the bolt thread before fitting, which sets firm and prevents vibration loosening. You will often see it as a blue residue on the old bolt. If Loctite was used originally, it must be reapplied on refitting or the bolt will work loose again. Clean the old Loctite from the thread and apply fresh blue Loctite 243 before refitting.
Metal locking tabSome machines use a metal tab that is bent up against a flat on the bolt head once tightened, preventing it from rotating. If this tab is worn, bent back flat, or missing, the bolt will work loose. Check whether one is fitted and replace it if damaged or absent.
Spring-loaded locking washerSome machines use a spring washer under the drum pulley bolt that provides constant outward pressure to prevent loosening. If this washer is missing or has lost its tension, replace it before refitting. A standard flat washer is not a substitute.
Nyloc nutSome models use a nyloc nut with a nylon insert that grips the thread and resists rotation. Nyloc fasteners should ideally be replaced rather than reused, as the nylon insert compresses on first use and provides less grip when reused. Use a new nyloc nut if available for your machine.
The bolt needs to be firm and secure, but excessive torque risks shearing the bolt off in the drum shaft. If the bolt shears, removing the broken stud requires specialist tools, and if it cannot be extracted, the drum or complete tub assembly may need replacing at significant cost.
Belt Tension: How Tight Should the Belt Be?
On older washing machines, belt tension was adjusted by loosening the motor mounting bolts and sliding the motor to increase or decrease the belt’s tightness. On most modern machines, the motor is fixed and belt tension is not adjustable. If the belt is too slack on a modern machine, it needs replacing rather than adjusting.
Correct belt tension
Pluck the belt like a guitar string. It should give a clear, resonant ping. When pressed sideways at the midpoint between the two pulleys, there should be approximately 6mm of movement in each direction. The belt should feel taut but not rigid.
Incorrect belt tension
A belt that flops rather than pings is too loose and needs replacing. A belt that has no give at all and feels drum-tight is overtightened, which puts excessive strain on the motor bearings and drum bearings and will shorten their life significantly.
If your machine does have an adjustable motor, the front motor bolt is typically fitted on a slotted hole rather than a fixed hole. Loosen this bolt, slide the motor to achieve the correct tension, then retighten. Recheck tension after a few test cycles as the belt beds in.
How to Fit a New Drive Belt
Fitting a new drive belt is straightforward on most machines but can be awkward on models without a removable back panel. The process varies depending on access.
With a removable back panel
-
Disconnect from the mains and remove the back panel. On most front-loading washing machines, the back panel is held by several screws around the perimeter. Remove these and lift the panel clear.
-
Locate the motor pulley and drum pulley. The motor pulley is the small wheel on the motor shaft. The drum pulley is the large wheel at the back of the drum. The belt runs around both.
-
Loop the belt over the drum pulley first. Place the belt in the groove of the drum pulley and hold it in position. Feed the belt under the motor pulley and begin slowly rotating the drum pulley by hand. The belt will wind progressively onto the drum pulley with each turn until it is fully seated.
-
Check tension and alignment. The belt should sit centrally in the groove of both pulleys with no sign of tracking to one side. Pluck the belt to confirm correct tension.
Without a removable back panel
Some machines have a fixed back panel with only a small inspection opening. On these machines, the belt must be fitted from above after removing the lid. This is significantly more difficult.
Remove the lid and look down to locate both pulleys. Hook the belt onto the motor pulley first, then feed it onto the drum pulley while slowly rotating the drum by hand. The main difficulty is the belt slipping off the motor pulley before it can be seated on the drum pulley. One useful technique is to use a cable tie to temporarily hold the belt against the motor pulley while seating it on the drum pulley. Remove the cable tie completely once the belt is fitted.
Need a repair or spare parts?
If the belt fault points to worn bearings, a cracked motor bracket, or a damaged drum pulley, a professional engineer is the right next step. For straightforward belt and pulley replacements, our spare parts guide points you to trusted UK suppliers.
Frequently Asked Questions
Why does my washing machine belt keep coming off?
A belt that comes off repeatedly points to an underlying fault, not just a one-off event. The most common causes are a worn or stretched belt that needs replacing, a loose drum pulley bolt, or a worn drum pulley. Less common but possible causes include loose motor fixings, a cracked motor mounting arm, a broken drum bracket, or failed drum bearings. Work through each cause in the order listed above, starting with the simplest checks.
Can I refit the belt myself, or do I need an engineer?
Refitting a drive belt is one of the more accessible DIY washing machine repairs, provided you have access to the belt via a removable back panel. The process does not require specialist tools and is straightforward on most mainstream machines. The difficulty increases on machines without a removable back panel, where the belt must be fitted from the top. If the cause of the belt coming off is a deeper fault such as failed bearings or a cracked motor bracket, that repair is significantly more involved and an engineer is recommended.
How tight should a washing machine belt be?
A correctly tensioned belt should give a clear ping when plucked, like a guitar string, and have approximately 6mm of lateral movement when pressed sideways at its midpoint. A belt that flops or sags is too loose and should be replaced. A belt with no give at all is overtightened and will put excessive strain on the motor and drum bearings. On most modern machines, tension is not adjustable, so a slack belt needs to be replaced rather than adjusted.
What is Loctite and why do I need it on the drum pulley bolt?
Loctite is a threadlocker compound, a liquid that sets firm when applied between threaded fasteners, preventing vibration from working the bolt loose. It is commonly used on drum pulley bolts because the vibration of the spin cycle would otherwise gradually loosen even a firmly tightened bolt. You can identify its previous use by a blue residue on the old bolt thread. If Loctite was originally used, it must be reapplied when refitting, or the bolt will work loose again and the belt will come off repeatedly. Blue Loctite 243 is the standard medium-strength version suitable for this application.
My washing machine belt came off once but went back on fine. Do I need to do anything?
If the belt came off during an unusually heavy or unbalanced load and has not come off again, it may have been a one-off event. However, it is worth inspecting the belt for wear and checking that the drum pulley bolt is firm. If the belt shows significant wear or fraying, replace it before it fails completely during a wash cycle. A belt that has stretched will come off again under similar conditions.
The drum has some movement when I lift it near the door seal. Does that mean the bearings have failed?
A very small amount of play is normal and does not necessarily indicate bearing failure. The amount of movement matters: if you can clearly see the drum lifting several millimetres when pushed upward, and particularly if the machine has been increasingly noisy on spin over recent months, bearing failure is the likely cause. A machine with collapsed bearings will eventually seize, and the repair cost typically makes replacement the more sensible option. Read: what do worn drum bearings sound like?
Where can I buy a replacement washing machine drive belt or drum pulley?
Drive belts and drum pulleys are available for most mainstream washing machine brands through independent spare parts suppliers. You will need your exact model number, found on the rating plate inside the door rim, to order the correct part. A belt or pulley specified for the wrong model will not fit correctly and may cause further problems. See our spare parts guide for recommended UK suppliers.
Clothes come out of washing machine hot
Laundry should always come out of the washing machine cold – the final rinse cycles use cold water. If clothes are coming out hot or noticeably warm, the most likely cause is that the cold water inlet hose is connected to the hot water tap instead of the cold. This is more common than it sounds and is sometimes not discovered for months or years.
A washing machine rinses with cold water in the final stages of every cycle. Laundry coming out genuinely hot – rather than just slightly warm – is always a sign that something is wrong with the water supply connection.
What Temperature Should Laundry Be Coming Out?
Clothes coming out of the washing machine should feel cold because they have been rinsed multiple times in unheated cold water. The exact temperature varies with the seasons – in winter the cold water supply is colder, so laundry will feel noticeably cold and wetter. In summer, the cold supply is warmer, so laundry may feel closer to room temperature and appear drier, but it should never feel genuinely warm or hot.
Normal: Cold or coolClothes feel cold to the touch after the final spin. In summer they may feel closer to room temperature. This is correct behaviour.
Problem: Warm or hotClothes feel noticeably warm or hot after the cycle. The rinse water has been heated – this should not happen and indicates a connection fault.
Why Clothes Come Out Hot: The Most Common Cause
If laundry is coming out hot, the cold water inlet hose is almost certainly connected to the hot tap rather than the cold. Most modern washing machines are cold fill only – they take in cold water and heat it themselves when needed. If the inlet hose is accidentally plumbed to the hot supply, every fill and rinse uses hot water, including the final cold rinses that are supposed to cool the laundry down.
This fault is more common than it appears. In some cases households use the machine for an extended period without realising the connection is wrong – particularly if the previous plumber or installer made the mistake and no one has checked since. The symptoms are often written off as the machine running hot, rather than being investigated as a plumbing fault.
Rinsing in hot water wastes significant energy, damages certain fabrics and dyes, causes laundry to come out badly creased, and over time can affect the machine’s internal components and seals. It should be corrected as soon as it is identified.
Why It Is Not Always Obvious From Looking at the Hoses
The hose connections may appear correct at first glance – hot tap on the left, cold on the right, matching the colour coding on the hoses. But in some installations the taps themselves are in the wrong position, or the pipes behind the wall are crossed, so the tap labelled cold is actually delivering hot water. The only reliable check is to turn the cold tap on with the machine disconnected and confirm that cold water flows out before reconnecting.
For a full explanation of how to check the connection and all the other possible causes of hot or creased laundry, see our guides on laundry coming out badly creased and misconnected washing machines.
Is the Laundry Just Warm Rather Than Hot?
If the laundry is slightly warm but not hot, this is usually normal and does not indicate a fault. Some warmth after a full wash cycle – particularly at higher temperatures – can persist into the final spin. See our guide on should the washing come out warm or cold? for a clear explanation of what is and is not normal.
Need Help With Installation or a Fault?
If the connection has been corrected but laundry is still coming out hot, there may be an internal fault with the machine’s temperature control system.

Frequently Asked Questions
Why are my clothes coming out of the washing machine hot?
The most likely cause is that the cold water inlet hose is connected to the hot tap instead of the cold. Modern washing machines are cold fill only and use cold water for rinsing. If the cold supply is actually hot water, every rinse cycle delivers hot water, and laundry comes out warm or hot rather than cold.
The hoses look correctly connected – how can it still be a plumbing fault?
The taps may be labelled correctly and the hoses colour-coded correctly, but the underlying pipework can still be crossed – meaning the cold tap delivers hot water and vice versa. The only reliable check is to disconnect the cold inlet hose, open the cold tap, and confirm that cold water flows from it before reconnecting.
Is warm laundry always a problem?
Slightly warm laundry after a high-temperature wash cycle is normal – some residual warmth can persist into the final spin. Genuinely hot laundry, or laundry that consistently comes out warm on all programmes, indicates the rinse water is being supplied warm or hot rather than cold. See our guide on whether washing should come out warm or cold for more detail.
What damage can rinsing in hot water cause?
Hot rinse water wastes significant energy, damages heat-sensitive fabrics and colour dyes, causes laundry to come out badly creased, and can over time affect internal rubber seals, hoses, and other components not designed to handle continuously hot water. It should be corrected promptly.
Fabric Softener taken out too soon
If fabric softener is not working or the laundry has no softener smell, the conditioner is most likely being siphoned out of its compartment too early – during the early rinses rather than the final rinse. The most common causes are mould or residue in the dispenser drawer causing water to splash into the conditioner compartment, overfilling the compartment, or high water pressure.
Fabric softener that is released too early in the cycle gets rinsed away before it can soften the laundry. Understanding how the conditioner compartment works makes it much easier to identify why this is happening.
How the Fabric Conditioner Siphon System Works
The fabric conditioner compartment uses a simple but precise siphon mechanism to hold the conditioner until the correct point in the cycle, then release it automatically.
You add conditioner – poured into the fabric conditioner section of the drawer, up to but not above the maximum fill line.
The cycle runs – the conditioner sits undisturbed in its compartment through the wash and early rinses. Water is directed away from the conditioner compartment during this phase.
The final rinse – water is directed into the conditioner compartment, flushing the conditioner out into the drum. The small plastic tube at the back of the compartment then siphons away any remaining water.
The problem – if extra water enters the conditioner compartment early and raises the level above the top of the small siphon tube, the siphon is triggered prematurely, pulling the conditioner up and out of the compartment long before the final rinse.
The siphon is triggered the moment water (or conditioner) spills over the top of the small tube inside the compartment. Even a small amount of stray water entering early in the cycle can trigger it – the conditioner does not have to overflow visibly.
Common Causes of Early Release
Mould and residue in the dispenser housing
Build-up of black mould, gunge, or old detergent residue in the top of the soap dispenser area can cause water to spray or splash sideways into the conditioner compartment rather than flowing where it should. Cleaning the drawer and the housing behind it regularly prevents this. See our guide on black jelly in the soap drawer.
High water pressure
If the water pressure to the machine is higher than normal, water entering the dispenser during wash or rinse cycles can splash over into the conditioner compartment. This is more likely to occur if the water supply pressure has recently increased or the inlet tap is fully open.
Jammed dispenser nozzle
On machines with a directional nozzle – a lever-operated system that redirects water between the detergent and conditioner compartments – a jammed or sticking nozzle can direct water into the conditioner section at the wrong point in the cycle. For more detail on this system, see our guide on fabric conditioner not being taken out.
Overfilling the compartment
Filling the conditioner compartment above the maximum fill line – or filling it to the maximum and then closing the drawer firmly – can cause the conditioner to slosh over the siphon tube immediately, triggering premature release before the cycle has even started properly.
Every conditioner compartment has a maximum level indicator – usually a thin raised line on the inside of the compartment. Filling above this line and closing the drawer briskly is enough to trigger the siphon immediately. Always fill to below the line and close the drawer gently.
How to Check and Fix Each Cause
-
Remove and thoroughly clean the drawer and the housing behind it. Pay particular attention to the top of the housing where water sprays in – mould and residue here is the most common cause. See our guide on how to remove the soap dispenser drawer. -
Check and reduce the water supply pressure if possible. Try partially closing the isolation tap on the cold water inlet hose to see if reduced pressure stops the splashing. -
Inspect the dispenser nozzle if your machine has one. With the drawer removed, check that the nozzle moves freely and returns to its default position. A stiff or jammed nozzle may need replacing. -
Fill the conditioner compartment more carefully. Never exceed the maximum fill line and always close the drawer gently rather than pushing it firmly shut.
Still Having Problems With the Dispenser?
If cleaning the drawer and adjusting the fill level does not resolve the fault, the dispenser mechanism may need replacing.

Frequently Asked Questions
Why is my fabric softener not working even though I put it in the drawer?
The conditioner is most likely being released too early in the cycle and rinsed away before it can work on the laundry. This happens when stray water enters the conditioner compartment during the wash or early rinses, triggering the siphon mechanism prematurely. The most common causes are mould or residue in the dispenser housing, overfilling the compartment, or high water pressure.
How does the fabric conditioner compartment release the softener at the right time?
The compartment uses a siphon system. A small plastic tube at the back of the compartment acts as a siphon trigger point – when water fills the compartment during the correct rinse cycle, it rises above the top of the tube and siphons out the conditioner into the drum. If water enters the compartment earlier than intended, the siphon is triggered prematurely and the conditioner is washed away.
Can overfilling cause the conditioner to be released too soon?
Yes. Filling the compartment above the maximum fill line – even slightly – means the conditioner level is already close to the siphon trigger point before the cycle begins. Closing the drawer firmly can then slosh the conditioner over the tube, starting the siphon immediately. Always fill to below the maximum line and close the drawer gently.
Could mould in the soap drawer cause this problem?
Yes. Mould and residue build-up in the top of the dispenser housing can obstruct the water flow channels and cause water to spray sideways into the conditioner compartment during wash and rinse cycles. Removing and thoroughly cleaning the drawer and the housing behind it – especially the top section – often resolves the fault.
