Hi David
I have a Hygena APL8224/1 dishwasher, it suddendly stop washing. I manage to figured out that the circulation pumb was wasn't working.
Dismantle the circulation pumb and carried out buzzer test on coils and noticed there is a temperature fuse is attached to the coil and it was blown out.
it cost me only £0.67 to replace.
I would suggest, check for any faulty fuses before buying any parts.
