I have a Bosch Tabletop dishwasher which has started to fuse the house. It will run fine until it heats the water to a certain point. Then it will trip out the Main circuitbreaker. once it has cooled down sufficiently it will run again for a bit, then trip the house out again! Any ideas? It doesn\\\'t melt the fuse in the plug or trip the sockets. Just the Main.
