Re: Bosch Dishwasher Heat Pump Failure?

Thanks for all the replies to my post.

The NTC wiring in the diagram that Martin posted is the same as mine, and the resistances look good. While there is one less heater terminal on mine, I am now sure that the heater itself has blown.

Still trying to figure out why I don’t see a voltage on the connector during the wash cycle. I have had the control PCB out, and there is nothing obviously wrong with relays or soldering.

I’ll order up a spare heat-pump, and hope that I don’t have to buy a new controller as well!

Re: Bosch Classixx not heating water

Hi Rob,

Did you manage to solve this one? I have a heat pump with the same wiring (2 x red + green / yellow) and I’m not sure how to diagnose a heater fault.

Any help would be appreciated.

Cheers,

Philip
