At first I thought this was another broken control knob but this time knob was fine, tried a known good facia/control board to no avail.
The display is stuck on 1.22 and turning the knob has no effect. It appears to start whatever wash 1.22 is the set time for but the display cannot be altered at the outset.
I am guessing that the main pcb is faulty, anyone come across this?
