Noisy Tumble Dryer

This article is about faults that can cause a noisy tumble dryer. However, due to the way dryers are designed, many tumble dryer noises can be difficult to fix because you need to strip the entire dryer down to get to some parts. This article gives general guidance without specific stripping down instructions.

Tumble dryers, particularly condenser and heat pump dryers can be complicated to strip down and get back together!

Metallic scraping noise

Metallic scraping noises should not be ignored. This sound usually means the metal drum is scraping on something as it revolves. If ignored, serious wear can occur.


As you can imagine, something metal constantly catching on something else – even something else metal – will inevitably result in wear of one or both of the parts involved. I’ve seen many simple faults ignored until only a very expensive repair will fix it.

Other metallic scraping noises could be caused by the plastic bearings the drum rests and rotates on wearing down so much that the lip of the drum at the front can scrape on metal.

Make sure the dryer is level. If not level the cabinet can slightly twist causing drums to catch on nearby parts. Hotpoint and Indesit tumble dryers used to be terrible for scraping noises, and they brought out modifications to try and address the problem.

It’s hopefully solved by now, but cheap dryers, or even expensive ones not well made, can have flimsy casings which twist easily and have too little clearance between the revolving drum and the back panel.


Squeaking noises

These can be caused by tension pulleys which usually tension the drive belt and revolve all the time the drum is turning. They are small wheel-like plastic parts that are held against the drive belt with strong springs, and run on a small metal shaft. They commonly dry out or wear.

The proper cure for this is to replace the pulleys and the shaft they run on, or at least strip them, clean them and grease them with high melting point grease if they aren’t too worn. Unfortunately though these tension (or jockey) pulleys are not usually accessible without stripping the dryer down though some dryers allow you to remove a side panel if you can work out how to take it off.

Squeaking bearing

On some tumble dryers are dry or worn bearing can cause squeaking noise. This is particularly common on some Indesit or Hotpoint tumble dryers. Check out the comments below where 2 people have contributed their experience on how they dealt with their squeaking tumble dryers.

Rumbling noises

Deep rumbling noises can also be caused by the same belt tension pulleys from the last section. Depending on their design they can develop squeaks or a rumble. So can worn drum bearings, which are usually just shiny plastic parts the drum rests on at the front and a single brass bearing at the rear centre of the drum.

Noisy motor

The motor can of course become noisy, though it is pretty rare because they revolve so slowly that they don’t tend to wear much. If the belt is removed and any tension pulley brackets moved out of the way a motor can be run on its own to see if it’s creating the noise.

Warning: refitting a tumble dryer drive belt can be extremely difficult. They are very strongly tensioned and special tools are often needed to be able to force one back on, especially with a brand new belt.

Condenser dryer noises

Condenser tumble dryers have more parts than vented dryers and one which can cause noises is the small pump which pumps condensed water into the condenser drawer. If this pump becomes noisy it should be a different noise to the noise of the drum revolving and should continue even when the drum pauses when reversing.

The condenser pump may run continuously during the cycle, or it may be designed to kick in and out intermittently during the cycle. If it develops excessive noise it may need replacing. This water pump can develop a loud screeching noise. Access may be available from the rear panel but some may need side panels and frontages removing.

    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

    Yes it would be better if you could leave it in situ and then pull it out to investigate when the noise starts

  4. Hi, I have an Indesit tumble dryer and it squeaks when hot.mi took the back bearing cover off and there was quite a lot of black dust laying in the casing. The tear drop bearing looked OK, still round, could it still be that as a cause… 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.

  6. 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.

  8. 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
