This machine has been reliable although I changed a noisy pump a couple of weeks ago. It worked fine for several washes afterwords.
Now it doesn’t fill at all, then reports a H2O error and, if left switched on, eventually changes to reporting a F-01 error.
The water supply is ok and the solenoids both work ok (I independently powered them and water flowed ok), so I assumed that it must be the controller (a Mk 6 board).
I’ve replaced it with another from EMW Electronics (programmed for this machine)… and get the same results. I checked the door interlock (just in case there was a voltage drop across the contacts) but that seems ok too.
Any idea what else I may have missed?
