OK,

So, we have four possibilities :

Damaged heater (in the tub).

Damaged thermistor (on the front of the tub).

Damaged wire(s) between heater/thermistor assembly and control board.

Damaged control board.

You should be able to test the thermistor circuits at the control board.
Connector CN3 pin 3(wht) to CN3 pin 6 (orng) and read approximately 13,000 ohms st room temperature across the two wires in the harness.

Do you have access to a multi meter to test the circuit ?

The remainder of the tests and checks will require you to remove the top, control panel, and front panel, to access the heater and wiring,
and visually inspect the wires and heater for damage, you can also circuit test the the heater for an open fuse, you should read resistance across the two heater terminals if the built in fuse is OK and no visible damage to the heater coil.


Here are the instructions from the service manual,so you can access the components.

Good Luck,
:) :) :)

Devils,

A proper model number would be better, so we can assist you properly, but,

With what you supplied, I have to think you have a MAH 87 or 9700, model.

The "tE" code, in your display indicates a water temperature or heating component problem.

There are several components involved and several tests that should be done, based on the model number.

We'll be better able to assist you, with the model number.

Thanks,
:) :) :)
