My Kitchen Aid suddenly stopped turning on. The control panel lights at the top of the door will light up when pushed, but when the start button is pressed the lights simply stay on until you shut the door, and then they turn off without starting the dishwasher. They are supposed to instead flash when you press the start button and then turn the dishwasher on when you shut the door. I replaced the door switch, and it worked for about two weeks after that, and then stopped working again in the same way as the first time. So I replaced the door switch again but this time that did not fix the problem.

The control panel button are lighting when pushed, so it does not seem like a fuse problem. Any ideas how to fix this? Thanks.
