I s there anyone on Mumsnet who about electricity?
Earlier this year my old DW started tripping the switch in the box so we got rid of it. My MIL gave us one that she had in the garage. She couldn't remember what was wrong with it or if there was anything wrong. It never really worked properly and among other things the switch tripped. We then aquired another off Freecycle. It is quite a new one and in excellent condition. It's been working well for a couple of months then suddenly it's started tripping the switch. Arrrrghh!!! Anyone got any ideas? I need my dishwasher. Is there anyone who knows anything about electricity or has a partner who does?
