Hi I have a washing machine pluged into a socket inside my kitchen cupboard. The washer went wrong so we got a new one, on removing the old washer we found that the face of the socket behind the plug had melted and turned brown and the plastic around the pins of the plug had melted including the black bands (safety plug) allowing the pins to wiggle. The socket looked perfectly normal until the plug was removed and could have been like it for months without realising. Just wondering what caused this? p.s. the socket has been replace and the wire behind was fine and the cause of the washer to go wrong was a faulty motor sensor.
