Water fills but wont run
I have a Whirlpool (Model # WDF520PADM7) I bought about a couple years ago. When you select any cycle and push start, the dishwasher fills with water and heats up. It will not run. It seems to go through the cycle because the detergent door will open and after the correct amount of time, the clean light comes on, but the dishes are still dirty. I checked the door switch and it is operating fine. Any suggestions?
