Noisy Tumble Dryer

💡
Quick Answer

Tumble dryer noises most commonly come from the belt tension pulleys, worn drum support bearings, or – if the drum is scraping – something the drum is catching on as it rotates. The type of noise is the most useful diagnostic clue: metallic scraping, squeaking, and rumbling each point to different components. Many tumble dryer noises require significant strip-down to repair, as internal components are not accessible without removing the front or side panels.

Tumble dryers – particularly condenser and heat pump models – are more complex internally than washing machines and can be significantly harder to disassemble and reassemble correctly. This guide covers fault diagnosis by noise type. Specific strip-down instructions depend on the model and are not covered here.

Metallic Scraping Noise

🚫
Do not ignore a metallic scraping sound

A metallic scraping noise means the drum is catching on another component as it rotates. Continuing to run the dryer will cause progressive wear on both components involved – a simple, inexpensive fault can quickly become a serious and expensive one if left unaddressed.

Metallic scraping from a rotating drum has two main causes:

🥁

Drum catching on the casing or back panel

Budget dryers and some poorly built premium models can have flimsy casings with insufficient clearance between the drum and the rear panel. If the machine is not level the casing can twist slightly, closing this clearance further and allowing the drum to catch. Check that the dryer is level front-to-back and side-to-side. Some Hotpoint and Indesit models were particularly prone to this fault and received design modifications as a result.

🔩

Worn front drum support bearings

The drum rests and rotates on plastic support bearings at the front of the machine. As these wear down, the front lip of the drum drops and can begin to scrape on the metal surround of the front panel opening. This is a progressive fault that worsens with continued use. Replacement bearings are available from Spares4Appliances, though access typically requires front panel removal.

Squeaking Noises

Squeaking is most commonly caused by one of two components – both of which require strip-down to access on most machines.

⚙️

Belt tension pulleys (jockey pulleys)

Tension pulleys keep the drive belt correctly tensioned as the drum rotates. They are small plastic wheel-like components held against the belt by a strong spring and running on a small metal shaft. Over time the shaft dries out or wears, producing a persistent squeak that runs continuously while the drum is turning. The correct fix is to replace the pulley and shaft assembly. As a temporary measure, stripping and greasing the shaft with a high melting-point grease can resolve a squeak that is caused by dryness rather than wear.

🔘

Dry or worn rear drum bearing

The rear of the drum is typically supported by a single brass or plastic bearing at the centre of the rear panel. A dry or worn rear bearing produces a squeak or whine that follows the drum rotation. This is particularly common on some Hotpoint and Indesit tumble dryers. Access to the rear bearing generally requires full strip-down of the machine.

Rumbling Noises

A deep rumbling noise that follows the speed of the drum rotation usually points to the same components as squeaking – belt tension pulleys and drum bearings – but in a more advanced state of wear. Depending on the design and condition of the pulleys, the noise may present as a rumble rather than a squeak. Worn front drum support bearings and the rear drum bearing can also produce rumbling as they degrade further.

How to confirm the noise is drum-related

If the rumble changes character or stops when the drum pauses to reverse direction, this helps confirm the noise is drum-related rather than from another component. A noise that continues through the reversal pause is more likely to be from a pump or motor.

Noisy Motor

Motor noise is relatively uncommon in tumble dryers – the motor runs at comparatively low speed and tends to last well. If the motor is suspected, it can be isolated for testing by removing the drive belt and any tension pulley brackets and running the motor alone. If the noise disappears when the belt is removed and the motor runs quietly in isolation, the noise was coming from the belt system rather than the motor.

⚠️
Refitting the drive belt is difficult

Tumble dryer drive belts are very strongly tensioned. Refitting a belt – particularly a new one – often requires a specialist tool to stretch it onto the motor pulley. Even experienced engineers can find this challenging. If the belt needs to be removed for diagnosis, be prepared for the refitting process to be the most difficult part of the job.

Condenser and Heat Pump Dryer Noises

Condenser dryers have an additional component that vented dryers do not – a small pump that transfers condensed water into the collection drawer. This pump may run continuously during the drying cycle or may cut in and out intermittently.

A failing condenser pump can produce a loud screeching or rattling noise that is distinct from the drum-related sounds described above. The key diagnostic clue is that pump noise continues when the drum pauses to reverse direction – drum-related noise stops or changes at this point. If the pump develops excessive noise it will need replacing. Access varies by model – some allow rear panel access, others require front or side panel removal.


Need an Engineer?

Most tumble dryer noise faults require significant strip-down. A qualified engineer can diagnose and repair the fault correctly.

Quick Reference: Noise Type and Likely Cause

Noise type Most likely cause Action
Metallic scraping, continuous during drum rotation Drum catching on casing or worn front support bearings Level the machine first. If persists, front panel strip-down needed
Squeaking, follows drum rotation Dry or worn tension pulleys or rear drum bearing Grease or replace tension pulleys – strip-down required
Rumbling, follows drum speed Worn tension pulleys or drum bearings, more advanced stage Strip-down required – do not delay, wear will worsen
Screeching or rattling, continues when drum reverses Condenser pump (condenser/heat pump dryers only) Pump replacement – access varies by model
Noise disappears when drum reverses Drum-related: bearings, pulleys, or scraping See metallic scraping and rumbling sections above

Frequently Asked Questions

Why is my tumble dryer making a scraping noise?

A metallic scraping sound almost always means the drum is catching on another component as it rotates. Check the machine is level – an unlevel dryer can twist the casing enough to reduce the clearance between the drum and the rear or front panels. If levelling does not help, worn front drum support bearings are the most likely cause. Do not continue running the dryer with a scraping noise – progressive wear will make the repair more expensive.

What causes a squeaking noise in a tumble dryer?

Squeaking is most commonly caused by the belt tension pulleys drying out or wearing. These small plastic wheels run continuously while the drum turns and are held against the belt by a strong spring. Greasing or replacing the pulleys and their shaft resolves the noise in most cases, but access requires stripping the dryer down. A worn or dry rear drum bearing can produce a similar noise.

My condenser dryer makes a screeching noise – what is it?

On a condenser or heat pump dryer, a screeching noise that continues when the drum pauses to reverse direction is likely to be the condensate pump rather than a drum-related fault. The pump circulates condensed water into the collection drawer and can develop a loud noise when it begins to fail. The pump will need replacing – access depends on the model.

How do I know if the noise is from the drum or the motor?

Listen carefully when the drum pauses to change rotation direction. A noise that stops or changes at this point is drum-related – bearings, pulleys, or scraping. A noise that continues unchanged through the reversal pause is more likely to be from the motor or, on condenser dryers, the condensate pump. A motor can also be tested in isolation by removing the belt and running the machine briefly – though be aware that refitting a tumble dryer belt can be very difficult.

Neil 5 replies I had the modification done on my Hotpoint dryer in June. It started with a mild 'squeaking' soon after. This is now very pronounced, but only squeaks when rotating in one direction. Called customer services this morning to report the fault that I think has only developed post modification and was told that it had nothing to do with the modification. Questioned this stance as how could the customer services operator determine the nature of the fault without a report from an engineer. Your thoughts / recommendations please.

Hello Neil. It’s possible that stripping it down and reassembling could introduce something. If the squeak started the next time you used the dryer or was reported within days or a week of the modification they might be more likely to suspect a link. However, it’s just as likely if not more so that it’s not related but as you say no one can be sure without seeing it.

Neil

The dryer has stopped making the squeaking noise. This is due to it now not rotating in one direction.
Could be terminal. Repair or Replace ?
Under and to the rear of the machine is a dark powder. I suspect this is from a drive belt.
The link to Junes modification will not be acknowledged by Hotpoint, but there had been no squeak before.

Hello Neil. Drive belts are black so an issue with the belt should produce black rubber. I can’t see a belt problem causing faults turning one way only though. Dark coloured powder could be from a dry bearing possibly. Unfortunately when they carry out these modifications they are unlikely to bother with anything else so if the bearing was already a bit worn they may just ignore it as they are under a lot of pressure to carry out as many of these modifications as possible. They are even advertising for people to do nothing but these modifications on a 6 to 12 month contract and these people will be trained only to do the modification and are likely to know little or nothing about anything else.

It’s just not possible to say that these faults are caused by the modification (or not) without someone looking at it. However, many faults can start up any time without warning. I always remember early on in my career I called out to service a washing machine that was 5 years old and had never had a fault. All I did was tighten the belt, oil the suspension and clean the filters, it looked fine. But 3 days later the main program timer failed and the woman refused to believe it was nothing to do with me. It made me wary of servicing appliances that were apparently working ok from that day on.

Hi Neil.
re: black dust….I had the same issue, the source of the dust was the bearing at the back. It was either from the bearing/drum shaft/the back panel of the machine (where the shaft was wearing through).
The shaft on my drum was attached with rivets, I drilled them out and fitted a new shaft, and a new bearing. The problem only returned weeks later.
TBH I eventually gave up and got a new machine, the hassle it was causing eventually got the better of me.

When fitting new bearings try using a little bit of copper grease, its only about £2 on ebay. Should prolong the life of the bearing.

Ivor 3 replies If only I could get the casing off my Indesit IS31V tumble dryer, maybe I could see if the belt is broken. Any help would be appreciated.

Hello Ivor. You shouldn’t need to take the casing off to check the belt. With the lid off you should be able to see if the belt is attached because it should wrap around the entire drum. If it is broken or fallen off you should normally see the mark where it used to run. If it is there you should be able to try lifting up the belt to see if it is tightly attached to the motor or of it is loose.

Tumble dryers can be quite difficult to strip down these days and often need the back, kick panels and side panels and sometimes in control panels removing to get access to various parts.

Ivor

Likely replying to Andy Trigg (Whitegoodshelp)

Thanks Andy, but I don’t have a top on my dryer, it’s all in one, sides, top etc.
I’ve got the casing loose but the front control panel seems to be holding it on and with no visible screws I think it must be simply a push on fit and clip in and I don’t want to try and wrench it off in case I break a hidden fixing.

Andy Trigg (Whitegoodshelp)

Likely replying to Ivor

Ivor, I’m not familiar with that type. There may well be screws behind the front kick panel if fitted. Another way to test if the belt is on or not is to try turning the drum by hand. If the belt is properly on it should have quite a strong smooth resistance. If the belt is broken it should move very freely or maybe freely for a bit then jamming if the belt has come off and tangled up. If the belt feels like it’s still on and the drum is not revolving it could be a capacitor, the motor, the drum jammed, some electrical fault or connection problem or even the pcb. I would definitely get an engineer in if so.

Kelly 2 replies My indesit dryer was mega squeaky. Googled and checked my rear bearing. Sure enough it was almost sheared through. I replaced it, now on my third washing since changing and now its squeaking again. I have checked to make sure I havnt been given a dud but all is in order. Any ideas on what else it could be? Google isnt being very helpful this time.

Hello Kelly. As my article mentions, squeaking can be caused by a bearing although that is just as likely to sound like metallic scraping noise. The most common cause of squeaking is from the tension pulleys on the drive belt. They are difficult to get to as you have to strip the dryer down and with many modern tumble dryers if you take off the drive belt it can be very difficult indeed to get it back on. Some manufacturers have even manufactured special tools to put the belt back on. So I would be very careful. If you suspect the small pulley wheel that puts tension on the drive belt you could try spraying some WD-40 into it taking care not to get any on the belt or the motor. If that stops the squeaking, if only temporarily it will at least show that this is the source of the squeak. Other than that it’s a question of literally trying to locate the noise with the ears.

Hi Andy, This maybe of some interest to you and other people who get problem’s with noises from their tumble driers. I have just repaired a tumble dryer ( INDESIT IDC75 ) for my mother, which had a loud screeching noise coming from it for several months when being used. I first checked the rear drum bearing as nearly all of the comments on the forums say is the cause of this noise, but that was not the cause of the noise at all , It was in fact the water pump on the lower back right hand side. It had a fair amount of built up dust inside of it, so I cleaned it all out and the ends of where the rubber water pipe attaches to it also, and it has got rid of the noise. I hope this can be of help to more people.

Julie 2 replies My hot point dryer starts okay, then a few minutes into cycle squeals at varying degrees of irritation. The decision was new tumble dryer. That gave me permission to strip it down to source the noise. It sounds like from the water pump. I have removed that pump and the noise has gone. Sooooo new plan buy a new pump £51 and re fit. Hoping this will fix. Will get back to you and let you know outcome. I have always blamed the belt or the main motor!!!! Question should I go even deeper into the water pump and replace bearings or go for the new part?!?!? Thanks.

Hi Julie. I’d be amazed if you could buy bearings for the pump. Pumps just come complete these days with no option for repairing.

Hey Andy

Thanks I will go for a the part.

Do water pumps squeal?!
When putting ear to location it sounded from this part. So fingers crossed

Hello John. I can only guess the drum isn’t aligned properly for some reason, or maybe the metal shaft that runs inside it also needed replacing.

Mrs W ROWE 1 reply Brand new Hotpoint condenser tumble dryer becomes noisy after about 20 minutes, should this be a normal thing or is there something wrong with the pump?

That’s unusual. Unfortunately the noise is something that an engineer really needs to hear. What kind of a noise is it?

Andy Trigg (Whitegoodshelp)

Likely replying to Alan

Hello Alan. I mention common causes for squeaks in my article above. The teardrop bearing on most tumble dryers is pretty rubbish and often fails. It seems to be made of quite soft metal. However, to be fair when you have a drum shaft running inside a metal bearing you do need the metal bearing to be the softest element so that when the inevitable wear occurs, it occurs on the much cheaper and easier to replace bearing. Having said that, I’m pretty sure they would stand being better quality than they are.

One way to test if it is that bearing is to try squirting some WD-40 into it. But ideally you need to identify where the noise is coming from with the ears if you can run the dryer with the lid and back panel off.

Andy Trigg (Whitegoodshelp) 1 reply Yes it would be better if you could leave it in situ and then pull it out to investigate when the noise starts

Andy Trigg (Whitegoodshelp) 1 reply That sounds awful Caroline. Something could be catching metal to metal but with noises like that you have to have the machine out and trace where the noise is coming from with eyes and ears.

Thanks Andy, we had it out on Sunday but unfortunately the noise didn’t happen. Am thinking it may be something expanding with heat but heat may not have reached the temperature with the back and sides off the machine. Did a test yesterday with it in situ. The noise started after about 10 minutes, I put the cycle on pause for a minute and started it again – no noise. It did appear back and I let it run but the noise stopped before the cycle finished.

I will take it out again at the weekend and leave it run for longer to see if we can trace the source.

Thanks again

Likely replying to James Bradley

Hello James. That doesn’t sound like a tumble dryer at all. I don’t know of anything in a dryer that runs so fast as to make that kind of noise. I would check the small pump that pumps condensed water into the drawer. The best way to troubleshoot an appliance noise is to take off the lid and if possible the back panel and locate where the noise is coming from.
