Bosch Maxx WFL 2260 makes noise when rotating

Bosch Maxx WFL 2260

When the drum goes around, it’s noisy. How to describe… You know Jeff Wayne’s “War Of The Worlds”, where the Martian cylinder has landed and the end is unscrewing, and it’s a sort of scraping sound? A bit like that.

I suspect it’s the motor. What’s the best way to confirm that, and do motors have bearings that can be replaced? Or should I look around for a replacement motor?

At first I was thinking drum bearings, and emailing to ask for a price for them. But then I removed the drive belt — the drum then rotates quietly, but if I spin the motor, that’s noisy. So maybe my email didn’t get through, and maybe I was lucky it didn’t!

I have replaced the brushes on this motor 3 times. The last time they weren’t worn down fully, one of the brushes had actually split. So maybe there’s vibration or something?

The machine still works, maybe it will keep going until the lockdown is over, but when it’s making noise like that I’m thinking it’s not long for this world, one way or another, or at least part of it isn’t.

it its the motor bearing you can get a bit of wd 40 into them and they quieten down

if its not that some of the armatures have ca plastic covering that can come loose and can be removed if need be but you would have to strip the motor

Thanks!

This is great, I’ve gone from thinking I was going to lose the machine altogether, to 30 quid and the bank holiday weekend gone on stripping it down to replace the drum bearing, to only having to replace the motor, to now, possibly, just a bit of WD40.

Incidentally, when I’m taking the motor out I have to tip the machine onto its front and take the motor out the bottom. That works but seems awkward, and the drum is then suspended in a way it wasn’t necessarily designed for. Is that an amateur way of doing it, i.e. is there an easier way?

I won’t have a chance to play with the machine again until Monday evening, or maybe Tuesday. Will post again afterwards to say how it goes.

Thanks again

no real easy way of getting motor out but you can add wd on bearings without removing motor
tilt at 45 degrees and climb underneath and you can get the rear on. spray little bit at a time then turn the motor to work it in. and take kit roll with you for excess

Well, it sounds a good bit better now. Thanks Dave. I’m no audiophile to know whether it’s perfect, but it’s way better.

I took the motor out because I don’t like being underneath. Put some WD40 on the axle and spun it as you said, turned the motor up the other way and did the same at the pulley end, underneath the pulley. Then did the same with some lubricating oil because I never really think of WD40 as a lubricant.

Then I thought to check the drain filter for FOD. Wouldn’t open. Disconnected the pump, removed 5 cent. It’s past my bedtime so I didn’t do any more cleaning or look for any more trouble, just put it back together, did a quick rinse cycle and drain to see if it was leaking, and that’s enough for today.
