Hi there, my second hand washing machine has started tripping out the electricity. It starts fine, fills up ok, then when it starts the actual wash it trips out. I am able to spin clothes and the machine empties fine, it seems to happen when the water has just heated up and it starts to turn the washing, any ideas? I had the guys out who sold it to me and they suggested putting a new plug on so I want to be armed with some onfo when they next try to fob me off!
