What do Hotpoint Aquarius lights flashing mean?
Hotpoint Aquarius washing machines without a digital display indicate faults through flashing LED lights rather than text error codes. This guide covers the flashing light error codes for models including WMA30, WMA31, WMA32, and WMA33. The same codes may apply to other Aquarius models using LED indicators.
This guide applies to basic Aquarius models with LED indicator lights only. Aquarius models with a digital display show text codes such as F1 through F15 and are not covered here.
Quick Reference: Flashing Light Error Codes
| Flashing light | Meaning | Action |
|---|---|---|
| Door lock light | Door not properly shut, or door lock fault | Check door is fully closed. If still flashing, door lock may need attention. |
| Wash light | Programme selector dial moved after cycle started | Do not touch the dial during a cycle. Light should clear at end of programme. |
| Pre-wash light | Water fill fault | Check tap is on, hoses are not kinked, and water supply is normal. |
| End light | Machine has been paused | Press Start/Cancel to resume. If unresponsive, cancel programme and restart. |
| Final spin light | Out of balance – spin aborted | Redistribute the load and restart the spin cycle. |
| All lights | Critical error – cycle abandoned | If a one-off, try restarting. If recurring, call an engineer. |
Door Lock Light Flashing
If the door lock indicator light is flashing, the first check is whether the door is fully closed. Push it firmly shut and see if the light clears. If the door is properly closed but the light continues to flash, there may be a fault with the door lock mechanism itself.
When the door closes correctly, the door catch engages the lock and activates it. If the catch is not operating the lock properly – due to a worn catch, a misaligned door, or a faulty interlock – the machine will not start. See the full guide: how does a washing machine door lock work?
Wash Light Flashing
The wash light flashes if the programme selector dial is turned after a wash cycle has already started. This is a common occurrence when the dial is accidentally knocked, or if someone – particularly a child – moves it during a cycle. The machine registers the unexpected dial position as an error.
The light should stop flashing and the machine should continue or complete the programme without further intervention. Avoid turning the programme dial while a cycle is running.
Pre-Wash Light Flashing
A flashing pre-wash light indicates a water fill fault. The machine’s software has detected that the correct amount of water did not enter the drum within the maximum allowed time.
The first checks are straightforward: confirm the cold tap supplying the machine is fully open, and that the inlet hose is not kinked, twisted, or blocked. Low water pressure or a blocked inlet filter can also cause fill faults.
For full diagnostics: washing machine not filling with water.
End Light Flashing
The end-of-cycle light flashes when the machine has been paused. Press the Start/Cancel button to resume the cycle. If the machine does not respond, try cancelling the programme entirely and starting a new cycle from the beginning.
Final Spin Light Flashing
A flashing spin light means the out-of-balance detection system has intervened and aborted the spin cycle. This is not a mechanical fault – the machine has detected that the load inside is unbalanced and has stopped spinning to avoid excessive vibration or drum movement.
The laundry will be very wet as a result. Open the door, redistribute the laundry evenly around the drum, and restart the spin cycle. This should only happen occasionally. If it happens consistently, the loading pattern may need adjustment.
See the full guide: why is the spin light flashing at the end of the cycle?
All Lights Flashing
All lights flashing together indicates a critical error. The wash cycle has been abandoned. This is one of the less specific fault indications – the technical manual lists a range of potential causes including faults on the motor, pump, drain hose, pressure switch, and pressure chamber, as well as various wiring and connection issues.
If this is a one-off occurrence, unplug the machine for a few minutes, then plug it back in and try a new cycle. If the fault repeats, an engineer will be needed to diagnose the specific cause. See: book an appliance repair engineer.

Frequently Asked Questions
What does a flashing pre-wash light mean on a Hotpoint Aquarius?
A flashing pre-wash light indicates a water fill fault. The machine has not received the correct amount of water within the allowed time. Check that the cold tap supplying the machine is fully open, that the inlet hose is not kinked or blocked, and that the water pressure is normal. See: washing machine not filling with water.
The spin light is flashing and the laundry is still wet – what do I do?
The machine’s out-of-balance system has detected an unevenly distributed load and stopped the spin cycle to prevent excessive vibration. Open the door, redistribute the laundry as evenly as possible around the drum, and restart the spin cycle. This is not a mechanical fault.
All the lights are flashing on my Hotpoint Aquarius – what does this mean?
All lights flashing together is a critical error indicating the wash cycle has been abandoned. Potential causes include faults on the motor, pump, drain system, pressure switch, or wiring. If it is a one-off occurrence, unplug the machine for a few minutes and try restarting. If the fault repeats, an engineer will be needed to diagnose the specific cause.
Why is the door lock light flashing when the door is closed?
If the door is fully closed but the door lock light continues to flash, there may be a fault with the door lock mechanism itself, or the door catch may not be engaging the lock correctly. This could be caused by a worn catch, a misaligned door, or a faulty interlock. See: how does a washing machine door lock work?
Does the Hotpoint Aquarius WMA30 use the same error codes as WMA31, WMA32, and WMA33?
Yes – the flashing light error codes described in this guide apply to WMA30, WMA31, WMA32, and WMA33 models, and may also apply to other Aquarius models using LED indicator lights rather than a digital display. Models with a digital display use text codes such as F1 through F15 instead.
Samsung DE Error
The DE error code on Samsung washing machines typically means the machine believes the door is open – even when it is visibly closed. This guide explains what causes the DE error and how to diagnose whether the door lock, door latch, wiring, or PCB is responsible before replacing any parts.
DE on a Samsung washing machine means the machine thinks the door is open – it is not getting power passed through the door lock. The cause may be a faulty door lock, a worn or broken door latch, a loose wire connection, or in rare cases a PCB fault. Check the simpler causes first before replacing parts.
Mains voltage is present at the door lock. Always disconnect from the mains before handling any internal component.
Does a DE Error Mean the Door Lock Is Faulty?
Not necessarily. Replacing the door lock does not always resolve a DE error. The Washerhelp forum contains a documented example of this: Samsung washing machine DE error discussion.
Before replacing the door lock, work through the possible causes systematically.
What to Check Before Replacing the Door Lock
Is the Door Closing and Latching Properly?
When the door closes, the latch on the door pushes into the door lock body and should click firmly. This physical action operates a component inside the lock that activates it – simultaneously locking the door and passing power through to the rest of the machine. If the door latch is worn, broken, or has a spring displaced, it may not push the lock mechanism far enough to activate it – even if the door appears to close normally.
A door that has dropped slightly at the hinge due to wear may also fail to align properly with the lock, preventing reliable activation. Check whether the door latch aligns squarely with the lock opening when closed.
Is the Lock Mechanism Stiff or Sticky?
It is possible for a door to close and latch mechanically without fully activating the electrical lock inside. If the lock mechanism has stiffened over time, a small amount of WD40 sprayed into the lock opening may free it. It is also worth trying to gently wiggle the door up and down once closed – on some machines this can engage a partially stuck lock mechanism.
Is There a Wiring or Connection Problem?
A DE error can also be caused by a loose, broken, or corroded wire on the door lock – either on the supply feed to the lock, the neutral return, or the wire carrying power from the lock to the rest of the machine once it has activated. Check all connections to the door lock for security and any visible damage before replacing the lock itself.
Could It Be a PCB Fault?
In some cases the fault lies in the main PCB rather than the door lock. However, PCBs are expensive and non-returnable if the fault is elsewhere. Do not replace the PCB without being certain it is the cause of the fault – exhaust all other possibilities first.
Main PCBs are very expensive and non-refundable if the part turns out not to be the fault. Only replace the PCB after all other causes have been ruled out by systematic testing.

Frequently Asked Questions
What does the DE error code mean on a Samsung washing machine?
DE means the machine believes the door is open – it is not receiving the confirmation signal from the door lock that the door is properly closed and locked. This can happen even when the door appears fully shut, because the error refers to the electrical state of the door lock, not the physical position of the door.
Will replacing the door lock fix the DE error?
Not always. A DE error can be caused by a worn door latch, a misaligned door, a connection or wiring fault, or a PCB issue – none of which will be resolved by fitting a new lock. Check all other possible causes systematically before purchasing a replacement. See the Washerhelp forum discussion for a documented case: Samsung washing machine DE error.
Could the DE error be caused by the door hinge?
Yes. A door that has dropped at the hinge due to wear may no longer align accurately with the door lock, preventing the latch from fully activating the lock mechanism. If the door appears to close but the latch does not click firmly into position, check whether the door is sitting level and whether the hinge shows signs of play or wear.
Is it safe to check the door lock myself?
Visual inspection of the door lock and latch with the machine unplugged is safe. Do not reach into the machine to touch the door lock while it is connected to the mains – mains voltage is present at the lock. Always disconnect from the power supply before handling any internal component.
AEG error code E35
Error E35 on AEG machines means the machine thinks it is overfilling. It will stop the cycle, run an emergency drain, and cycle the pump on and off. Possible causes include a faulty fill valve, pressure switch fault, leaking water circuit, faulty wiring, or a defective main board.
Error code E35 on AEG washing machines and washer dryers indicates an overflow fault. The machine believes it is detecting an overfill condition and takes protective action to prevent flooding.
What Causes Error E35?
The possible causes listed in AEG technical documentation are:
- Fill valve faulty
- Leaks from water circuit on pressure switch
- Pressure switch defective
- Wiring defective
- Main board defective
This is typical of many AEG and Zanussi error codes, where the code indicates a general area of fault rather than a specific component. Without specialist equipment and access to replacement parts to test, a DIY repairer is unlikely to be able to diagnose the precise cause unless something obvious is visible.
What Happens When E35 Triggers?
AEG technical information describes the symptoms as follows:
“Cycle stops. Emergency drain procedure. Drain pump continues to operate. (5 mins on, then 5 mins off etc.) OFF/Reset”
The error code steps in and aborts the wash before an actual overfill can occur. This protects the kitchen from flooding, but it also makes diagnosis harder – the overfilling cannot be observed directly because the machine cuts the cycle before it reaches that point.
Fill Valve Fault
If the fill valve is jammed open, water will continue to enter the drum even when the machine tries to stop it – including when power is switched off. This type of fault used to be more common but is now rare with modern water valves. If water is heard continuing to enter the drum after power is cut, a faulty fill valve is the likely cause.
For further background on how the fill and pressure system works, see: washing machine overfilling.
How to Reset Error E35
There is no specific reset procedure beyond switching the machine off (OFF/Reset). To check whether the fault persists, put the machine on a wash cycle. If the fault is still present it will abort again and display E35. If it completes without aborting, the fault may have cleared or been intermittent. If the error returns consistently, an engineer will be needed to investigate the cause.

Frequently Asked Questions
What does error E35 mean on an AEG washing machine?
It means the machine has detected an overflow condition – it believes water is rising beyond the correct level. The machine aborts the cycle, activates an emergency drain, and cycles the pump on and off until the error is cleared. Possible causes include a faulty fill valve, pressure switch fault, leaking water circuit, wiring fault, or defective main board.
How do I reset error E35 on an AEG washing machine?
Switch the machine off to reset it. To confirm whether the fault has cleared, run a wash cycle. If E35 appears again and the cycle aborts, the underlying fault is still present and needs investigation. If the cycle completes without error, the fault may have been intermittent.
Can I fix AEG error E35 myself?
Possibly, if something obvious is visible – such as a visibly leaking water circuit connection or a fill valve that fails to close when power is cut. However, E35 covers several possible causes including wiring and main board faults, which require specialist diagnosis. If nothing obvious can be found, a qualified engineer is the recommended course of action.
What does Hotpoint Error Code F05 mean?
Hotpoint error code F05 on a Hotpoint or Indesit washing machine means the pressure switch is stuck in the “full” position – the machine thinks it still has water inside and refuses to spin. The most common cause is a blocked pump filter or drain hose. But the water draining away does not always clear the error – a blocked pressure tube can also keep the switch triggered even when the drum is empty. This guide explains all the causes and how to work through them.
Fault guide from Whitegoods Help – written with the expertise of our founding engineer’s 40 years of appliance repair experience.
Always unplug your washing machine from the mains before opening any access panels, touching the pump filter, or removing any hoses or tubes.
Some washing machine components can carry an electrical charge even after the machine appears to be off. If you are not confident working on electrical appliances, book a qualified engineer instead.
Which machines show the F05 error code?
F05 appears on a range of Hotpoint and Indesit washing machines – both brands are manufactured by the same company (now owned by Whirlpool following Indesit’s acquisition in 2014), which is why they share the same error code system.
The error appears in two ways depending on your model:
- Digital display models: the code “F05” appears on the display panel
- LED indicator models (no digital display): the 2nd and 4th indicator lights on the panel flash simultaneously
Many websites describe F05 simply as “a draining problem” or “the machine can’t empty the water.” This is misleading. Draining failure is the most common cause of F05, but it is not the only one. You can have a perfectly drained drum and still get F05. Understanding the correct explanation is essential for diagnosing and fixing this fault properly.
What does F05 actually mean?
F05 means the pressure switch is stuck in the “full” position – it is telling the machine there is water in the drum when there should not be.
The pressure switch has a critical safety job. Before a washing machine begins its spin cycle, it needs confirmation from the pressure switch that the drum is empty. If it spun with a full drum, water would be thrown out through the soap drawer, door seal and other openings. So the machine waits for that confirmation signal before spinning.
F05 means that signal is not arriving – the pressure switch is still reporting “full” when the machine expects to see “empty.”
There are three distinct reasons this can happen, and they require different approaches to fix:
| Cause | What is happening | Is water visible in the drum? |
|---|---|---|
| Drainage failure | The water has not pumped away – the drum genuinely still has water in it, and the pressure switch is correctly reporting full | Yes – water visible |
| Blocked pressure tube | The water has drained away, but a blockage in the thin pressure tube is trapping air pressure, keeping the switch triggered in the “full” position | No – drum is empty |
| Faulty pressure switch | The water has drained away and the tube is clear, but the switch itself is physically stuck and will not reset to “empty” | No – drum is empty |
Faulty wiring connections and, in rare cases, a faulty PCB (control board) are also listed as possible causes – but these should only be considered after all the above have been ruled out. Do not replace a PCB speculatively. On Hotpoint and Indesit machines, new modules are unprogrammed from the factory and require a dedicated smart card and reader to set up – a process that can cost over £200 on top of the part itself.
For more background on how washing machines control water levels, read our guide: how does a washing machine control water levels?
How to diagnose and fix the F05 error – step by step
Step 1: Is there water in the drum?
Look through the door. Is there visible water still in the drum? This is your first and most important question – it determines which path to follow.
If yes – water is still in the drum: the fault is a drainage failure. The pressure switch is doing its job correctly; the problem is that the water has not pumped away. Follow the steps below to clear the blockage.
If no – drum is empty but F05 is still showing: skip to Step 4. The drainage is working but the pressure switch is not resetting.
Step 2: Manually drain the machine
If there is water in the drum, you need to drain it before you can access the pump filter safely. Here is how:
-
Unplug the machine from the mains.
-
Open the small access panel at the bottom front of the machine. On most Hotpoint and Indesit models this is a rectangular flap that can be pulled open by hand or unscrewed.
-
Place a shallow tray or bowl on the floor in front of the panel, with some towels underneath.
-
Look for a small emergency drain hose tucked to one side of the filter cap. Pull out the end of this hose and remove its plug to allow water to flow into your bowl. Refill and empty the bowl until no more water comes out.
-
If there is no emergency drain hose, very slowly turn the filter cap anticlockwise – water will trickle out. Tighten it again, empty the bowl, and repeat until the drum is empty.
Step 3: Clean the pump filter
A blocked pump filter is the single most common cause of F05. Coins, hair clips, fluff, buttons and fabric debris all accumulate here and can prevent the pump from draining the drum properly.
-
With the drum now empty and the machine unplugged, unscrew the filter cap fully and remove it.
-
Pull the filter out – it may have debris wrapped around it or packed behind it.
-
Clean the filter thoroughly under a running tap.
-
Check inside the filter housing with a torch for any remaining debris, and check that the impeller (the small plastic wheel inside) can spin freely. If it is jammed, clear the obstruction.
-
Refit the filter cap firmly and close the access panel.
-
Also check the drain hose at the back of the machine – ensure it is not kinked, blocked, or pushed too far down the standpipe (it should be no more than 15cm into the standpipe).
-
Run a short spin cycle to test. If drainage completes and F05 does not return, the fault is resolved.
For more detail on this, see our full guide: washing machine won’t drain and washing machine pump filter guide.
Step 4: Check the pressure tube (if drum is empty but F05 persists)
If the drum is empty – either naturally or after cleaning the filter – but F05 is still showing, the pressure switch tube is the next place to check.
The pressure switch works using air pressure. A thin rubber or plastic tube runs from a small chamber at the bottom of the outer drum, up to the pressure switch. As water fills the drum, it compresses air in this tube, which pushes a diaphragm in the switch. When the water drains away, the air pressure should release and the switch should click back to “empty.”
If there is a blockage anywhere in this tube, the air pressure cannot escape – and the switch stays triggered in the “full” position even though the drum is empty.
Make sure the machine is unplugged before locating or touching the pressure switch or its tube.
To check the pressure tube:
-
Access the pressure switch – it is usually located near the top of the machine, behind the top panel or control panel. Remove the top panel (typically held by two screws at the rear) to access it.
-
Find the thin rubber tube running from the switch downwards toward the drum.
-
Carefully pull the tube off the base of the pressure switch.
-
If the tube was holding trapped air, you should hear an audible click as the pressure releases and the switch springs back to the “empty” position.
-
Inspect the tube for any visible blockage, kinks, splits or condensation.
-
If no click was heard, the pressure may have already slowly seeped out over time – this is normal if some time has passed since the fault occurred.
-
Reconnect the tube, refit the panel, plug the machine back in and run a test cycle.
For more detailed guidance on this: faults with the washing machine pressure system.
Step 5: Faulty pressure switch
If the drum is empty, the tube is clear and unblocked, but F05 still appears, the pressure switch itself may be faulty – stuck in the “on” position mechanically. A faulty pressure switch is relatively uncommon but does occur.
Replacement pressure switches for Hotpoint and Indesit machines are generally low-cost parts and widely available. However, confirming it is the switch and not the wiring or module first is important – check all wiring connections at the switch for signs of corrosion, burning or loose contacts before ordering a replacement part.
Find spare parts for your machine at our appliance spare parts finder.
Step 6: When to call an engineer
If you have worked through all of the above and F05 persists, the remaining possibilities – a faulty pump motor, wiring fault, or PCB issue – require test equipment and experience to diagnose safely. At this point, calling an engineer is the right move.
As noted above, do not replace the PCB speculatively. New control modules for Hotpoint and Indesit machines require a smart card programmer to initialise – a process that makes speculative replacement extremely costly.
Frequently asked questions
What does F05 mean on a Hotpoint washing machine?
F05 means the pressure switch is stuck in the “full” position – the machine thinks the drum still contains water and will not spin as a safety precaution. The most common cause is a blocked pump filter or drain hose preventing the water from draining properly. However, F05 can also appear even when the drum has drained successfully, if a blockage in the pressure tube is trapping air pressure and keeping the switch triggered.
What does F05 mean on an Indesit washing machine?
Exactly the same as on a Hotpoint – the two brands are made by the same manufacturer and share the same error code system. F05 on an Indesit washing machine means the pressure switch is jammed on “full.” Follow the same diagnostic steps described above.
Can I fix F05 myself?
In many cases, yes. If the cause is a blocked pump filter – the most common reason – this is a straightforward DIY task requiring no tools and no technical knowledge. Checking and cleaning the drain hose and pressure tube are also reasonable DIY steps. However, if the fault points to a faulty pump, pressure switch or wiring, and you are not confident working on electrical appliances, booking an engineer is the safer choice.
My washing machine drum is empty but F05 is still showing – why?
This usually means the pressure tube has a blockage that is trapping air pressure and keeping the pressure switch triggered in the “full” position, even though there is no water present. Removing the tube from the base of the pressure switch should release the trapped air with an audible click. If no click occurs, or if the error returns after clearing the tube, the pressure switch itself may be faulty.
How do I reset the F05 error on a Hotpoint washing machine?
There is no simple reset code that will clear F05 without addressing the underlying cause. Unplugging the machine for a few minutes may temporarily clear the display, but the error will return on the next cycle if the fault has not been resolved. You need to work through the diagnostic steps above to fix the root cause before the error will clear permanently.
Is F05 the same as F11 on a Hotpoint washing machine?
No. Both relate to drainage but they mean different things. F05 means the pressure switch is stuck on “full” – the machine is not receiving the signal that water has been removed. F11 means a direct fault has been detected with the drain pump circuit itself. If you have F11, check our washing machine not draining guide.
Error E52 on a Zanussi Washing Machine
Error E52 on a Zanussi washing machine means the control board is receiving no signal from the tachometric generator – the tacho coil on the motor. This tells the machine the motor is not running, even though power is being sent to it. The most common causes are a jammed motor or drum, a disconnected tacho coil or magnet, a wiring fault between the coil and the PCB, or – less expectedly – worn carbon brushes.
Always unplug the washing machine before opening it or accessing any internal component. Motor and PCB diagnostics involve accessing live components when powered – only carry out powered tests if you are competent and confident working with mains electrical equipment. See our DIY repair safety guide before starting.
Before investigating a specific error code, it is worth understanding how they work in general. Error codes identify which part of a machine’s self-diagnostic system has flagged a problem – they do not always point directly to the failed component. See our guide on appliance error codes: friend or foe? for more context.
What Does Error E52 Mean?
Error E52 is defined as “no signal from the tachometric generator”. The tachometric generator – commonly called the tacho coil – is a small coil mounted on the end of the motor armature. A magnet is attached to the armature and rotates with it. As each pole of the magnet passes the tacho coil, it generates a small electrical pulse that the control board uses to measure and control motor speed.
When E52 is displayed, the control board is sending power to the motor but receiving no pulses back from the tacho coil. It therefore cannot confirm the motor is running and shuts down the programme. There is no further fault information – the machine simply knows power is going in and nothing is being reported back.
Possible Causes of Error E52
-
Motor or drum physically jammed
The most commonly cited cause in technical documentation. If the motor cannot turn, no signal can be generated. Motor bearing failure is rare but possible. A jammed drum – from a foreign object, collapsed drum paddle, or seized bearing – will also prevent the motor from turning. This can be checked immediately: if you can turn the drum freely by hand with the machine unplugged, a physical jam can be ruled out.
-
Tacho magnet broken or detached
If the magnet on the end of the armature has cracked, fallen off, or become detached, the tacho coil has nothing to detect even though the motor may be running normally. A loose or missing magnet may also cause the motor to lose speed control and surge suddenly into high speed. Inspect the end of the motor armature for a damaged or missing magnet.
-
Tacho coil detached or failed
The tacho coil itself can physically fall off the motor end cap, or fail electrically. Both the coil and magnet can be inspected by removing the motor cover. The resistance of the tacho coil can be measured with a multimeter – but note that the resistance is typically very high and may appear close to open circuit on a non-digital meter. Check the expected resistance value for your specific motor before concluding it has failed.
-
Wiring or connection fault between tacho coil and PCB
A broken, corroded, or loose connection anywhere in the wiring between the tacho coil and the control board will prevent the signal reaching the PCB. Check the connector at the motor end and trace the wiring back to the board, checking each connector for corrosion, damage, or loose fit.
-
Worn or sticking carbon brushes
E52 is not the expected error code for carbon brush failure, but it has been reported as the cause in a number of real-world cases. If the brushes are so worn that they are not making consistent contact, the motor may be drawing erratic or insufficient current – which could indirectly affect the tacho signal. Check the carbon brushes even if this seems an unexpected cause. See our guide on diagnosing carbon brush wear.
Diagnostic Approach
Work through the causes in order of how easy they are to check, starting with the quickest:
-
Turn the drum by hand with the machine unplugged. If it turns freely, a physical jam is not the cause. -
Check the carbon brushes. Remove and inspect for wear. Replace if the brushes are short or not making clean contact. -
Inspect the tacho coil and magnet. Remove the motor cover and check both are physically present, intact, and securely attached. -
Check all wiring connectors between the tacho coil and the control board for corrosion, damage, or loose connections. -
Measure the tacho coil resistance with a digital multimeter. Compare the reading against the expected value for your motor – note the resistance is naturally high.
For more detail on the tacho coil, how it works, and this type of fault in a different manufacturer’s machine, see our guide on Hoover Nextra Error 7 – the same tacho coil fault on a different brand, with additional diagnostic information.

Frequently Asked Questions
What does Zanussi error E52 mean?
Error E52 means the control board is receiving no signal from the tachometric generator – the tacho coil – on the motor. The machine is sending power to the motor but cannot detect whether it is running. Possible causes include a physically jammed motor or drum, a detached or broken tacho coil or magnet, a wiring fault between the coil and the PCB, or worn carbon brushes.
Can I check whether the motor is jammed myself?
Yes – unplug the machine and try turning the drum by hand. If it rotates freely, a physical jam is not the cause and you can focus on the electrical causes. If the drum is stiff or locked, there may be a seized bearing, a jammed foreign object, or a motor bearing failure.
Why would carbon brushes cause error E52?
E52 is not the expected code for carbon brush failure, but it has been reported as the actual cause in several real cases. Severely worn or intermittently contacting brushes can affect motor performance in ways that indirectly produce unexpected error codes. It is worth checking the brushes as part of the diagnostic process even if they seem an unlikely cause.
What is the tacho coil and how does it work?
The tacho coil is a small sensing coil mounted on the end of the motor. A magnet attached to the motor armature rotates with it, and as each magnetic pole passes the coil, a small electrical pulse is generated. The control board counts these pulses to measure and regulate motor speed. If no pulses are received, the board cannot confirm the motor is running and triggers the error.
Is E52 repairable as a DIY fix?
Some causes – such as a loose wiring connector, a detached tacho coil, or worn carbon brushes – are accessible to a competent DIY repairer with basic electrical knowledge. Motor bearing failure or PCB faults are more involved and may be better handled by a qualified engineer. Always unplug the machine before opening it and follow safe working practices throughout.
Hotpoint Aqualtis and Indesit Error Code F02
Error F02 on a Hotpoint Aqualtis washing machine means the machine has detected a motor fault – either the motor is jammed and cannot turn, or the tachometric generator (tacho coil) is not sending a signal back to the control board. Start by turning the drum by hand with the machine unplugged. If it turns freely, the fault is likely electrical rather than a physical jam.
Always unplug the washing machine before opening it or accessing any internal component. See our DIY repair safety guide before starting any investigation.
Error F02 is a motor-related fault code. The official definition is “motor jammed or tacho off”, with the technical guidance to check motor and module connections. Understanding what this means in practice makes it much easier to diagnose the actual cause.
What Does Error F02 Mean?
The machine is sending power to the motor but receiving no confirmation that the motor is running. This information comes from the tachometric generator – commonly called the tacho coil – a small sensing coil on the motor that monitors a rotating magnet on the armature. As the motor turns, the magnet generates electrical pulses that the control board uses to confirm the motor is running and to regulate its speed.
When F02 is displayed, one of two things has happened: the motor physically cannot turn, or the tacho signal is not reaching the control board despite the motor running.
Possible Causes of Error F02
-
Motor or drum physically jammed
If the motor cannot turn, no signal can be generated. Check this first: unplug the machine and try turning the drum by hand. If it rotates freely, a physical jam is not the cause. If it is stiff or locked, look for a foreign object in the drum or pump, a seized motor bearing, or a collapsed drum bearing.
-
Tacho coil or magnet disconnected or failed
If the small magnet on the motor armature has broken off, or the tacho coil has fallen away from the motor end cap, no signal can be generated even if the motor is running normally. Both can be inspected by removing the motor cover. A detached magnet may also cause the motor to surge uncontrollably into high speed rather than running at the correct wash speed.
-
Wiring or connection fault
A loose, corroded, or broken connector anywhere between the tacho coil and the control board will prevent the signal arriving at the PCB. The technical advice for F02 specifically directs attention to motor and module connections – check each connector carefully for corrosion or poor fit.

Worn or sticking carbon brushes
Carbon brush failure is not the expected cause of a tacho fault, but worn brushes have been reported as the actual cause of motor-related error codes in practice. Check the brushes for wear even if it seems an unlikely explanation. See our guide on diagnosing carbon brush wear. For fitting replacement brushes on Hotpoint machines, see our guide on fitting new Hotpoint carbon brushes.

Control board (PCB) fault
If all wiring, connections, the tacho coil, and the motor itself check out correctly, the control board may be failing to process the tacho signal correctly. PCB faults are less common than the causes above and are typically diagnosed by elimination after other possibilities have been ruled out.
Diagnostic Steps
-
Turn the drum by hand with the machine unplugged. Free rotation rules out a physical jam. -
Check the carbon brushes. Remove and inspect for wear. Replace if they are short or making intermittent contact. -
Check all wiring connectors between the motor and the control board. Look for corrosion, damage, or loose fit. -
Inspect the tacho coil and magnet by removing the motor cover. Confirm both are present, undamaged, and securely attached. -
Consider the control board if all other causes have been ruled out.
Error F02 on the Hotpoint Aqualtis is the same underlying fault as Error 7 on the Hoover Nextra, and Error E52 on Zanussi washing machines. For a more detailed explanation of how the tacho coil works and how to test it, see our guides on Hoover Nextra Error 7 and Zanussi Error E52.

Frequently Asked Questions
What does error F02 mean on a Hotpoint Aqualtis?
It means the control board is receiving no signal from the motor’s tachometric generator (tacho coil). The official definition is “motor jammed or tacho off”. The machine is sending power to the motor but cannot confirm it is running. Possible causes include a physically jammed motor or drum, a disconnected tacho coil or magnet, a wiring fault, worn carbon brushes, or a control board fault.
How do I check if the motor is jammed?
Unplug the machine and turn the drum by hand. If the drum rotates freely, a physical motor jam is not the cause. If the drum is stiff or locked, look for a foreign object in the drum or pump, or a seized bearing.
Is F02 the same fault as Hoover Nextra Error 7?
Yes – both codes indicate the same underlying fault: no signal from the tachometric generator on the motor. The fault is also equivalent to Zanussi error E52. The diagnostic approach is the same on all three machines.
Can carbon brushes cause error F02?
F02 is not the expected code for carbon brush failure, but worn or intermittently contacting brushes can affect motor behaviour in ways that produce unexpected error codes. It is worth checking the brushes as part of the diagnostic process even if they seem an unlikely cause.
Is F02 repairable as a DIY fix?
Some causes – such as a loose wiring connector, detached tacho coil, or worn carbon brushes – are accessible to a competent DIY repairer with basic electrical knowledge. Motor bearing seizure or control board failure are more involved and may be better handled by a qualified engineer. Always unplug the machine before opening it.
