Hi Hillary
It could be that you have stopped it in a drain cycle - some dishwashers will start where they left off - turning the power off at the wall for a few minutes may help - failling that, go to the Howdens depot where it was purchased, and the store manager may be able to authorise a repair, even without the receipt. Of course, the tradesperson who bought the appliance may also have a copy of the invoice?
