    Very odd this one ,m/c lets in water but at a squirt at a time,sort of pulsing,i get volts to the valves but only every second or so plus there is no drum action either.Checked heater for insulation also checked motor,pcb looks ok but they always do :rolls: .

    this sounds like a timer problem

    this is a long shot but have had a few machines where the power supply to the board is through a capacitor. as these age the voltage on the board goes down causing all sorts of problems

    had a dishwasher the other week filled ok but as soon as motor kicked in it died ( just like a low battery )

    check timer board to see how power is suppplied to board

    hope this may help
