I have a whirlpool quiet partner III dishwasher. It quit working and the green light on the touchpad was blinking. After some research I determined that the control panel needed to be replaced. I did replace the control panel and the dishwasher ran through most of a cycle. It quit 45 minutes into the cycle and now is not getting power. Checked the breaker it is fine. I am considering replacing the thermal fuse and/or door latch what is the best way to determine what the problem might be?
