Dishwasher Doesn’t Run

First, check the Door Switch. The door switch is a safety device that will prevent your dishwasher from running if the door is ajar or it’s not locking or functioning properly.  If you have a defective door switch, it will not allow your dishwasher to run, even if the door is completely closed. You can test the door switch for continuity using a multi-meter. If the part does not have continuity, it must be replaced.

The Door Latch secures your dishwasher door so it does not open or leak water while running and also engages with switches in the door’s catch to supply power to your dishwasher’s controls. If you have a faulty latch, power is not being supplied to the controls and your dishwasher will not start. If the door latch is broken, it must be replaced. 

Another part that could be causing your dishwasher not to start is the Timer or Electronic Control. A good indication that you have a faulty control board is listening for the drain pump to sound. If you do not hear the drain pump motor running, the electronic controls are the problem. You can test the timer and electronic controls for continuity using a multi-meter. If there is not continuity, it must be replaced. 

The Thermal Fuse prevents your dishwasher from overheating and damaging other parts. When the thermal fuse is blown, it will prevent your dishwasher from starting. You can test the fuse for continuity using a multi-meter. If the part does not have continuity, it must be replaced.
