Bosch WFF140L fills and drains but the drum doesn’t turn.
I bought this last year, supposedly working, but have only just tried it out (it has been stored in my garage since last summer). It fills and drains but when the drum is supposed to turn, it doesn’t. It does make a sort of granching noise (hard to describe) but the drum doesn’t turn at all. It turns easily by hand and the bearings are fine. I would normally suspect the motor brushes or condenser but the strange noise suggests something else.
Any ideas?

I would defiantly check the brushes! 😉 sounds a very likely culprit.

I will check the brushes, but what could be making the strange noise?

I couldn’t tell you without hearing it could be a hundred.different things. 😉

Try it on a drain cycle only and see if the noise is still apparent . It may be a very noisy pump.
Re: Old Bosch machine – drum not turning – update / suppre
Update. The problem turned out to be the motor brushes – nice cheap fix.
Strangely, the machine worked for a couple of minutes with the new brushes then tripped the RCD. Further investigation shows that it trips the RCD even with the machine switched off. I’ve narrowed it down to the suppressor (mains filter) although it looks normal. So the next step is to either replace or bypass the suppressor, but I can’t help wondering why it should fail just after replacing the brushes. Is it just coincidence?

I wouldn’t, they never usually fail. 🙁

I’d take a closer look at that motor if I were you. 💡
