Dead, has power going into wiring, but wont do anything no lights or nothing could it be the thermal fuse?
It is almost definitely the thermal fuse. However, you also need to determine why it blew the thermal fuse. This fuse is in place to protect the Control Unit from overheating cause by to high of an amp draw from the motor, the heating element, or a dead short in one of the solenoids.
Replace the thermal fuse, which is located on the Control Unit, behind the Control Panel. After replacing the thermal fuse, start the dishwasher and using an amp meter, test the amp draw of the unit at the supply connection.
During the water fill, you should only see 0.1 to 0.2 amps at the most, and possibly could show 0.0 amps. Once the wash motor turns on, you should see somewhere between 1.2 and 1.8 amps. If the amp draw goes over 2.0 and stays there, you have a bad wash motor.
The best way to check the amp draw of the heater is to put the unit into a field diagnostic mode. To do this, cancel the cycle and wait for the unit to shut down (standby mode). In this order, press "HI TEMP WASH - AIR DRY - HI TEMP WASH - AIR DRY". Air Dry could also be labeled No Heat Dry or something similar. All of the LEDs will light up momentarily and the heat element will be turned on briefly. The amp draw of the heat element can read from 5.5 amps to 7.0 amps. If the amp draw of the heat element goes above 7.5, chances are that your heat element is bad and needs to be replaced.
