Re: Control board changed but machine not turning (Bosch)

So, the motor looks in pretty good nick inside, bit of carbon dust (duly wiped) but not too much, commutator not too worn, windings sound, no signs of overheating, didn’t detect any earth leakage.

But I’m surprised how quickly my replacement brushes wore out – 2/3 years when the originals lasted 15. How would this happen? And would it be sufficient to have blown the main board?

Re: Control board changed but machine not turning (Bosch)

Thanks for your quick response.

So now I have the motor sitting on my table. The brushes are indeed pretty low even though replaced them 2 or 3 years ago. Are budget ones (which they were) so inferior to genuine ones?

If the problem is anything other than brushes or cleaning is it bye-bye motor?

We did in fact have some RCD trips just before the machine failed, which I thought at the time were due to another toaster or kettle end-of-lifeing.

Not sure what you mean by ‘pin to pin’, can you spell it out for the hard of thinking 🙂
