When the drum bearings have gone in a washing machine they make a rumbling sound. Many people are unsure if the noise their washing machine is making is really worn drum bearings or something else. Be warned though, even if you know what they should sound like, as this article explains, there are other faults that can sound exactly the same.
As an experienced engineer even I’ve misdiagnosed worn drum bearings once before (and never made that mistake again). In my defence I was with another engineer and you tend to be less thorough when responsibility is shared. We were called out to a very noisy washing machine. We expected it to be the drum bearings. I opened up the door, spun the drum by hand and heard what sounded exactly like worn drum bearings.
After quoting the customer, it later transpired that the noise was actually coming from the motor bearings. That taught me that the only true way to diagnose them is to take off the drive belt so that when you spin the drum you are only spinning the drum – and not the belt and the motor too.
I’ve also come across one instance when another engineer ordered up a complete new drum and bearing kit for a customer after he’d done the same thing. I was sent out to fit them. As soon as I took off the back panel I could see the drive belt was in a bad way and the rubber had started to melt. When I took off the belt and spun the drum – the drum bearings were fine, so was the motor. Believe it or not the rumbling noise was caused by the damaged drive belt. It just needed a new belt. This last case is very unusual, but don’t be too hasty to diagnose worn drum bearings.
What do noisy drum bearings sound like?
It is a big help to know what sound to listen out for. This video shows a washing machine drum being spun when the bearings are clearly worn –

Is there play in the drum?
If the drum bearings are rumbling that’s one thing. But if when you pull the lip of the drum towards you it lifts up and down on the shaft then either the bearing at the front has collapsed, or the drum spider may have a crack in it or be corroded. In both scenarios it will complicate a repair and may need an entire new drum kit at great expense. It may well be beyond economic repair.

Have a 4 month old whirlpool that seems to grind a bit and sometimes Very loud when it pumps out the water during rinsing . Warranty by mechanic replaced the pump but there is still weird sounding grinding going on when the machine starts to remove water from the tub. Any advice. P.s. loudest washer we ever had.
Thanks

Hello Jeff. If it only makes a noise when it is emptying water it can only be the pump, or something stuck inside the pump like a button, or coin, or some other falling object. If it makes the grinding noise as soon the pump starts up but only lasts a second or so then it may just be that the pump they use is noisy. Some pump impellers rattle as they start up. But if the noise lasts for longer, and especially if it comes and goes there is possibly something stuck inside there that is being sucked in and tossed around. If this is the case, and especially if it is a plastic object they can be difficult to get out.
This is because if you lay the washing machine over to work on it the object can float back up inside the sump hose, or even inside the drain hose. In such a case once most of the water has been pumped away it is best to just disconnect the washing machine from the mains, and with the back panel off take off the sump hose and drain hose and then carefully inspect both hoses and inside the pump.

It sounds like my bearings on the drum are gone on my washing machine , how much would you charge to fix it please
Andy Trigg (Whitegoodshelp) says
Hello Neil. You can usually get a free quote from one of my repairers Appliance repairs. It is usually a very expensive job but some of my repairers have schemes in place for paying monthly and even covering the whole of the washing machine for future repairs over the next 12 months so it might be worth investigating.
