Our dishwasher will rinse the dishes, drain and go into the wash cycle where it stays and the water does not heat up. We have put in a new heater module and that has not helped. Is there anything you can suggest?
Here are your parts includes a wiring diagram.
I have no info on Thermador’s so cannot be very specific.
Perhaps the thermistor/high limit at the top of Section 4 in the parts is shot.
Looks like it should be 4 connector.
The two for the hi-limit should be 0 ohms.
The NTC (temperature sensor) is probably up around 70,000 ohms but this is a guess. It,s resistance should decrease as temperature increases.
