I am a C&G qualified Radio TV & Electronics Engineer by trade.
At what connections can I test the heater/NTC can be ohms tested for continuity/resistance before I check current draw. If these are OC that narrows it down. Have you got resistance readings for these?
Is the control module in the door?
I have previously removed the the door panel and there are quite a few "Red" wires!
I want to rule the heater out a it would be beyond economical repair if it was OC. Which wires would it be?
My wife informs me that it doesn't do it all the time.
I've just run a 30min wash and after 10 mins opened the door to be greeted with hot water!
Rules out the heater.
Must be intermittent.
