Tracks around relay (heater?) are blown and the track from the on off switch gone. Meggered heater all ok and not o/c. Wiring in door intact. Could this have happened when the heater got hot? Tripped 32A MCB but didnt blow fuse? assume it has one but behind the dishwasher.
Regards
S.Re: Smeg DWI710E1 blown tracks on PCB
Often just caused by a dry joint on the heater relay gradually burning out and eventually flashing over to other tracks. If the centre of the damage is the heater realy I would suggest its nothing more than the pcb itself and maybe the heater wire terminals. If the machine has a seperate button and display board however it may have damaged this as well, Had a few like that and needed to replace both boards. If its a self contained single pcb then, assuming you have checked everything else I would just go for a pcb and terminals.
