I replaced the control panel. I based this decision on other comments and feedback. I was trying to decide if the control panel was bad or the main circuit board was bad. One feedback said to disconnect the control panel from the circuit board and after turning the power on and closing the door the Cancel cycle should run for about 2 minutes if the circuit board was working ok. After running this test and the Cancel cycle functioned correctly, I decided to replace the control panel. That was the correct decision. The dishwasher is working now. Diagnosing the problem took the most time. But is got the problem fixed on the first try.
