Hello, I have a maytag mdb4630aws2 dishwasher. The unit is brand new, when I plug it in the "normal" and "heated dry" buttons light up for ten seconds and then there is a click and the lights go off on the unit. Pressing buttons yields no response. Holding the cancel button for ten seconds yields no response. If I unplug the unit for a five minutes and start it up again I get the same two lights going on and then it shuts off.
