Dishwasher would not start one night after pressing the normal cycle and then start button. It would go straight to the cancel/drain and could hear the humming drain sound. Pressed all the cycles and will do the same. Called technician who came over and said we needed a new control panel board. Priced it at $135.55 here in Hawaii so said no. Went online and found one for $82.00 so decided to change it rather than buy a new one. Replaced it today and same thing is happening. Read somewhere online to do a diagnostic run by hitting heated dry, sanirinse, heated dry sanirinse. It caused all the buttons to turn on and go through a cycle, but again it does the same thing. Used kitchen sink to fill up the dishwasher to test it and the float in the right corner works fine and closed door and it drains fine. Did we just waste $82.00 on the control microprocessor when it was really the actual control panel - even more expensive a part?
