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.

Steven B 0 replies I will say one thing, some new dryers seem to vary in noise from nearly silent to bloody deafening. I'll just write of my recent tales of owning a tumble dryer. We had a Zanussi Condensor dryer, which we brought in 2009 and was still working when we brought another in January. The simple reason is this, that it was costing upwards of £4 a load at current prices. It was just unsustainable. It was also right on the verve of needing a new motor, diagnosed as failing and the part was nearly impossible to source, multiple trusted repairers tried and I did too. Turns out they only used this motor for a very short period before changing to a different part code which wasn't interchangeable. So, we brought a Indesit heat pump. Was on offer and cost just over £300. About as noisy as the Zanussi condensor, no biggie. Unfortunately the panel failed after 2 weeks. The retailer insisted in not repairing and replacing. We upgraded to a LG FDV909, which was whisper quiet. However it lasted 3 months before it failed and refused to work, flashing multiple error codes, the engineer from LG stated it needed a new motor and compressor. Marked it as uneconomical to fix. LG then emailed me a uplift number which the retailer then refunded me. Brought an Fisher and Paykel Series 9, didn't get to install it. Did you know (and the retailer didn't either) that it MUST be plumbed into the cold water supply, or it will just throw an error after a few mins and refuse to work? We didn't either. Here we go again. Now we have a AEG 9000 series absolute care. It's really effective, drying about a third quicker than the LG, but my god is it noisy. Probably louder than my old White Knight vented one that sounded like a train. The compressor gurgles all the time, the motor is LOUD and there is a faint but perceptible rattle, as if part of the fittings is loose. AEG says it's normal however. The 5 year warranty is what swung the purchase, as my mum has dementia and I do her washing, I needed it to work and be reliable, so I'm stuck with it. So FYI to anyone reading this, if you want an really effective dryer, look at the AEG. If you what quiet, look elsewhere.

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? This is the second Hotpoint condenser dryer we have had, should we change completely or is a condenser dryer normally like this please.

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) 0 replies Thanks for that Tony. I will add that to my article shortly.

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.

Nigel 0 replies I think the squealing noise could be the pump that gets rid of the water on a condenser dryer , some pumps only kick in after a while to get rid of the water when it needs to which is why it may be intermittent ,if the noise persists even though the drum stops to reverse etc it could be this pump motor ,

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 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

Thanks Andy, I’ll give that a try at the weekend

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
