ParticipantDave, your a star. I have just measured the current through the cycle. The motor seems to draw around 5a and the peak with the pump and heater is around 11a. It doesn’t seem to get larger than that. I have just run it through a complete cycle (using it plugged directly into the new socket) and it has gone OK. I can only assume that the original fault was, as you say, a faulty connection in the plug/socket. The subsequent triping of the extension lead must simply be an over sensitive thermal trip. I will now run it for a while and keep an eye on it, but think it is probably OK.
Really appreciate your help, most grateful. The wife will be delighted I have put the new dishwasher on hold….

ParticipantI have replaced both and checked the cable, which appear OK. However, the cable and plug do get noticeably warm when the dishwasher is running. Could it be that the main pump winding has partly shorted, so that when it is running in conjunction with the heating, it draws too much current? If so, is there a way to check this?

ParticipantThanks for the response. It is connected to an extension lead with a 13 a rating (3120 watt). I had assumed the red reset on the lead was a thermal trip, as the main ring main red does not fail. I am also concerned that the original failure over heated the plug (partly melted) rather than blow the 13 amp fuse. I had dismissed the earth leakage option as it only happens at two points in the cycle and if I reset the trip on the lead and move the clock on, it works fine….????
