Bosch SRS43A02GB/14 Dishwasher

[dena89]

Machine will not fill, no voltage to solonoid.
The microswitch on the regulator/pressure chamber,
is definately O/C, but shorting it out makes no difference.
Wash motor runs all the time, and anyone know what the
relay pcb on top of motor does? Is it 2 speed motor?
There is also a pulsing humming sound at times, which
stops as soon as I try to find out where its from.

Thing is dont want to order pressure chamber if Timer
is also faulty. Does the microswitch maybe need to pulse?
like flow meters?

Any help gratefully accepted.

Blimey so many questions 😆
I would start looking at the usual suspects…………namely
1/ Gunge in transfer tube from pressure chamber to sump housing
2/ Gunged up pressure unit
3/ Gunged up water matrix tank.

Those in any combinations can send the fill system into oblivion.
The reason the wash pump (make sure its not the drain pump 😉 ) is running is that it probably thinks it has water in the tank hence the no fill aswell 😀

Thanks,
As I said the microswitch on the pressure chamber is o/c.
the anti flood switch is fine , pump works if you lift lever by hand.
Guess will have to take chance and replace switch and chamber, as shorting
it out makes no odds.
Let you know if it sorts it.
