9/20014 Maytag dishwasher MDB7600AWS stopped washing - fill with water and drain - installed new control panel and computer board inside door. Re set and ran well until Oct 27, 20014. Began same behavior - checked back on line for all "reset tricks" 5times this and three times that, and shut off power source at least 1 hour - to no avail. What to do?? How many more hundred $ put into this 10 yr old dishwasher?
