Re: Bosch WFF 2000 Washing M/c – Drum Does Not Rotate

Thanks guys. The brushes did the trick. Cleaned up the commutator and replaced the brushes. Switched the machine on and it started up immediately.

One word of warning to others, though. The copper wire is fragile where it fits into the carbon brush. Broke one of them and had to get a second replacement from a friendly repair man.

Cheers

Re: Bosch WFF 2000 Washing M/c – Drum Does Not Rotate

Thank you Paul, I’ll change them out.

I read on another thread that there is an equivalent set of brushes: CBN9121 which is a lot less expensive. Are these suitable for my machine?

Cheers

Re: Bosch Classixx SGS45C02GB06 Dishwaseher Leaking

Absolutely, a license to print money if you ask me!

Every time the machine has leaked it has not been running. When in use, it has always seemed fine. Used in the evening ok, next morning there would be nothing then all of a sudden the machine would dump a small pool of fresh water on the floor, maybe a pint or 2.

Have you something in mind?

Thanks spimps, we really appreciate your help. Cheers

Re: Bosch WFF 2000 – Trips RCD of Mains Elec

Problem well and trully solved! A very good steer on the carbon-dust film which was definitely the source of the problem.

I cleaned everything I could. Took about 2 hours to do: unclipped all wiring and disconnected every electrical connector in turn and wiped them down with sheets of kitchen towel before reconnecting them. Then wiped down the surfaces and anything else I could get my hands on. Found evidence of tracking across 2 pins on at least one connector. I guess this could have been enough to provider the mAmps needed to trip the RCD.

Since had about a 20 washes including 5 x 90 deg C service washes and 8 at 60 deg C all without power tripping. Fantastic. Thank you very much for your advice. :worthy: 😀

PS. Do you think the buildup of carbon-dust film is normal over a period of time or is this an indication that the brushes have broken down and need to be replaced?

Re: Bosch WFF 2000 – Trips RCD of Mains Elec

Thanks again Gegsy. Will see if I can get it tested tomorrow and will let you know.

In the interim, how easy is it to get access behind the control panel?

Cheers. Gavin

Re: Bosch WFF 2000 – Trips RCD of Mains Elec

Thanks Gegsy. Problem is I just replaced the heater element yesterday. Is it likely that it (genuine part) would be defective on fit?

Have cleaned off all the carbon from the exposed wiring and terminals. Is it possible to get access behind the control panel? There imust be carbon behind there as it has come through to the programme dials behind the perspex.

Cheers, Gavin

Re: Bosch WFF 2000 – Trips RCD of Mains Elec

Thanks for the advice; makes sense about the arcing. I will try to clean it off. Is it possible that it has got into the inner workings of the controller or other sensitive parts?

One thing I didn’t say though was that when the power does trip it seems to happen at the same point in the wash part of the cycle – near the beginning of the main wash – particularly on the 60 deg C or above washes. Does this indicate a more specific issue?

Thanks, Gavin
