My Whirlpool Dishwasher was bought just over a year ago and was great until we moved home, had utility /kitchen done, put in dishwasher and it wont work. Flashed 7 times, then 6 times. Now its stopped flashing and wont go through diagnostic programme. It starts, fills and water is hot but it seems arms don't rotate? and I am at a loss as to what to do. Any help greatly apreciated. I hate washing-up!!!
