Hi Customer just phoned about this machine he said that it comes up with E20 but when playing with machine it also comes up with E40 and E90 then back to E20 can any one help please Les
E20 – drain fault.
E40 – door interlock fault.
E90 – communication error. (usually the blue cables between PCB main board and fascia PCB – contacts on fascia PCB (user interface) loose and oxidised. Remove plug to fascia PCB and clean edge connector; crimp plug to tighten and refit.
