Hi Dave

Forgive me but I don’t do a huge amount of washing and do not necessarily take a huge amount of notice of these things.

I’ll put an old board back in tonight and do a wash.

I never thought washing machines did full speed on wash? I thought they just rotate fairly steadily all the time until perhaps the rinse cycle or the spin cycle in particular.

I was doing to reading up and I think these old machines are triode controlled motors? Would that sound right for this age and model?

I have also sussed out some of the wiring. I am probably going to do a schematic when I get the time of where each wire goes. It doesn’t look that complex.

Funnily enough, I stumbled across another post on a forum with this exact same issue. The reply on there was check the pressure switch?

But seeing as the part of the circuit board that has blown feeds the motor, it must be the motor where the issue lies. The circuit board looks very well designed and built. I suppose that’s why it has lasted so long.

Furthermore, I’ve just tried to search for a motor just in case and cannot find one anywhere.

There are two motor options though in the Bosch spares catalogue one is motor and one is Motor type FHP? Not sure what that is presently but I suppose there is hope.

Thank you for the prompt
response.

I’d have to put old board back in and do a wash to confirm that.

I don’t recall so no. Only spin does it try to spin up and immediately stops. It’s too old to have any kind of sophisticated motion sensor for sure because I consider that.

It washes as normal.
