    Dishwasher drain pump runs constantly. No water in the base and the float switch is ok. Any ideas please? I’m thinking PCB? Any help greatly appreciated. Cheers. Steve.

    as long as house has RCD trips then yes sounds like a shorted triac on the board. if no trip check for earth fault as pump is fed live and switches neutral. have you tried disconnecting float switch ? in case its short inside although i assume you have checked for this
