Lets see what the error code is stored in there.
Open the door and look at the row of buttons and number then from left to right with 1 on the left.
Turn the dishwasher off.
Press and hold button 1 and 3 and keep them held in.
With them held in turn the dishwasher on.
After a few seconds the leds on the top will light up. When they do let go of the buttons.
Wait about 5 seconds then press button 1 once.
Now it will show the error code.
Let me know the code and then turn the dishwasher off.
Thanks for that. The error code is id0
I had a feeling you will get that if the heater and control board is fine.
Belive it or not this is more then likely the wash motor at fault. As on this motor it has a tacho. If the tacho on there goes open circuit then the motor washes at full speed and this skips the heat phase out so thats why its not heating the water up.
What you need to do is access the right hand side of the dishwasher and remove the right hand side panel.
There you will see the wash motor. On there you will see the wiring blocks. Disconnect the motor and there you should see 2 wires going to the back of the motor. I think there yellow from memory.
Test the them for contonuity and see if its faulty. If so then you need to replace the wash motor on this and that will then cure the fault and get it heating again.
Ive seen this fault quite a lot and given the error code it will be the wash motor at fault. Yes it doesnt sound right for a motor to cause a heating fault but when the tacho fails as i said it washes at full speed so it skips the heat phase out.
The tacho on the motor is roughly around 210 Ohms so if your getting 5.5K ohms then its way out of range.
To be honest i think every time ive have the id0 error code its always been the motor itself at fault causing the problem. The service manual does state it could also be a triac on the control board for the motor but ive never had to replace a control board for the fault before as its always been the motor at fault.
