    Afternoon all,

    going to look at my friends parents dishwasher today.

    when connected to the kitchen ring it trips RCD but they have since had it connected to an extension lead from the lounge and it doesn't trip.

    i was pre thinking that there maybe water at the socket.

    Does anyone one have any thoughts before I turn up of possible answers?

    dishwasher is about a year old.

    if the kitchen and lounge are separate circuits, there could be some leakage on the kitchen circuit and dishwasher is adding enough to reach the threshold of the RCD. a ramp test and an earth leakage clamp test would help.

    If the kettle is on the same circuit and (I assume) it doesn't trip the RCD, get them to try it on the suspect socket.
    One way or another, the tea will be ready for when you arrive.

    could even be a dodgy socket. a bit of resistance in either L or N could lead to an imbalance

    Well what can I say about the pic. It was at the DB photo 1.jpg photo 2.jpg

    both RCD's failed at first stage of testing.

    think that's his Zs. obviously there's a problem somewhere. could just be the MCB/s inflating the result.

    yep exactly what I thought the house is a bodge of wires and wires. moldy walls with metal faceplates, infact nearly everything is metal

    and with that reading i wouldnt want to live there.
