I'd first check to make sure you have 120 volts coming in with a multimeter.
Where you house power line connects to the main electrical of the dishwasher, Across Black and White should read 120 volts. There should be 2 wire nuts that connect the main power line to your dishwasher in the junction box underneath the dishwasher. Just remove the very bottom access panel and you will see that junction box. I've seen those wire nuts come loose/and or arc, and cause this problem.
Usually when the dishwasher acts dead, and your are getting 120 volts to the dishwasher, the cause is the thermal fuse went out. It snaps onto the side of your control board.
Hi Jake, Thanks for the quick response! I checked the voltage and have 120 volts. The wires are tight in the wire nuts and I don't see any signs of arcing there.
I then opened the top of the door to check the circuit board and the fuse. My tester shows an open circuit in the fuse. I am attaching a picture of the PC board and I see some discoloration on it at D16.
I also checked for resistance on the door switch and the circuit closes when depressing the door switch and the circuit is open when the switch is released.
I picked up a new thermal fuse from a local vendor my appliance dealer suggested but have not installed it, since I don't know what caused the fuse to blow.
What should I do now?
