Thermal Fuse
If the dishwasher won't start the thermal
fuse might have blown. The thermal fuse helps to prevent damage to the
dishwasher by turning off power so that it doesn't overheat. Once blown,
the thermal fuse will have to be replaced for the dishwasher to work.
Door Switch
The door switch, or switches, are sometimes
called interlock switches. The door switch prevents the dishwasher from
running while the door is open. If the dishwasher won't start, the
switch or switches might be defective. To access the door switches,
remove the control panel or inside door panel - depending on the model.
They can be tested for continuity.
Main Control Board
The main control board provides power to
nearly every component of the dishwasher. If the dishwasher won't start
the main control board might be defective. YOU should first check for
more common parts. Many times control boards are replaced unnecessarily
because the problem was not diagnosed properly.
Touchpad and Control Panel
If the touchpad is defective, the control
board might not get the signal for the selections made. If the
dishwasher won't start and the display doesn't seem to change properly
when the buttons are pressed, the touchpad might need to be replaced. On
some models the touchpad and control panel are sold together and will
need to be replaced at the same time.

Timer
The timer allows power to flow to the proper
parts at the proper times. If the dishwasher won't start, the timer
might be defective. Keep in mind that timers are often misdiagnosed as
the cause of a problem. Check other components first before replacing
the timer.
