hi there can anyone help on this question? I have a Zanussi Dishwasher only less than 2 years old and for the past month every time I use it, when its only running for a couple of minutes the plug in the wall gets red hot and it trips the main switch. My nephew who is an electrician came and changed the socket in the wall for me cos there was slight singeing on the socket but he said if he took the plug apart as its a sealed unit then it would render any warranty on the machine useless. Just wondering if anyone would know could there be a problem with the plug before I get the Repairman out. ta in anticipation
