I was out to this on Monday, customers dad had changed the pump, and in the process managed to get water on the module, causing the machine to work but water pump running continuously.
I had a look at the module and the only sign of damage was one of the relays had shorted. I replaced the relay with one from from a donor board. Tried it on and everything was ok.
Customer has done a few washes Mon, Tues and Wed, but today phoned to say that the machine had not completed the wash and H20 was displayed on the front.
I have looked through the known error codes, but can’t see H20 among them. I am guessing it is referring to a water fault ie no fill or no drain.
Any ideas before I go back out to her?
Thanks
