Bosch Dishwasher SHU5304UC/U11 died hear the end of cycle. The unit was near the end of its cycle since the heater was on and dishes were clean and drying. Now there are no lights, nothing displayed, and the washer won't start. Checked power to the unit at the door switch. Checked the door switch for continuity and am getting continuity at the appropriate terminals of the door switch. I am suspecting the control panel. All the plugs on the control panel are for the various features, but what might have caused the whole thing to go dead? I feel comfortable going in there at the component level, but don't have a clue as to where to begin. Any help or suggestions.
