    Machine will light up on its own when power is on , but not actually starting programme. The only thing i can find is when testing output fron mains filter pcb i’m getting 50Volts on the earth ?.Surely thats not right ?
    No faults on supply, or metalwork when pcb reconnected and machine seems to work ok once started. Any ideas

    I’m with Dave on this, sounds like a supply fault. Did you do a loop test on the socket before testing the machine ?.

    yes, did earth loop test which was fine.Think i have an old LG in the workshop, hopefully test that one for comparison.

    Unfortunatly didn’t have another one to compare. To be clear, socket tests ok,but when testing output side of pcb i’m getting 50v on earth terminal.
