Re: Fisher Paykel Dishwasher DW920 U1 error: SOLVED
Update: Looks like the problem is the wash motor start capacitor (4uF, 400VAC). I have an old 1uF 1000VDC capacitor which I connected in place of the original cap, in the hope that would give the motor enough energy to start. The motor now starts and the dishwasher runs though its cycle ok. So seems I had two problems at once: bad inlet valve and bad starter cap.
