In your PM you said did I reset the board ? is this the same as The Total reset described in the Service manual? if so it won’t let me do a reset it has no effect holding the S1 start/stop button and then turnig on the power.
So I’ll replace the ntc and take it from there, to help my customer and allow me to search for this water leak I’m going to uplift the machine and loan her an old’n
To report back on this fault, replacing the board behind the facia did the trick. Ran it over several days hoping to find the leak that may have caused the fault in the first place but never found it.
