Troubleshoot Why A Dishwasher Will Not Start With These 7 – Steps

Step-1. Incoming Power

You will need to find your breaker box and locate the breaker that is dedicated for your dishwasher.  Flip the breaker off and on even if the breaker looks like it is already in the on position.  Now go and try to start your dishwasher again.

Step-2. Reset Button

Some newer models of dishwashers have a reset button, if your dishwasher won’t start you can push the button to reset the control board to see if this will make your dishwasher start.  If your dishwasher won’t start after pushing the reset button, you can diagnose your dishwasher following the troubleshooting steps below.

Step-3. Door Latch Assembly

You will need to test the door latch assembly for continuity using a multimeter.  If the door latch assembly does not have continuity, the part is bad and will need to be replaced to fix the problem.

Step-4. Thermal Fuse

The thermal fuse is used as a safety device, if the dishwasher over heats the thermal fuse will blow, cutting off the electricity too the appliance.  You will need to test the fuse for continuity using a multimeter.  If the fuse does not have continuity, the part is bad and more than likely the reason why your dishwasher won’t start, once the thermal fuse has blown it cannot be reused.

Step-5. Touch Pad

If some of the touch pad buttons are working, but others do not, the touch pad will need to be replaced.


Step-6. Main Control Board

Visually inspect the main control board, look for a loose wire harness connection or a burnt or melted component on the control board.  If any of the mentioned damage is found, you will need to replace the board.

Step-7. Timer 

Inspect the manual timer and replace it if it is damaged.

Troubleshooting tip – A test meter can be a real time and money saver while troubleshooting the numerous electrical parts on a dishwasher.  Electrical parts can be diagnosed either bad or good quickly, instead of assuming that a dishwasher’s electrical part is faulty and replacing it, only to find out that the part wasn’t bad and the problem lies elsewhere with another broken dishwasher part.  If you don’t have a test meter, a digital meter can be purchased reasonably cheap online or from one of your local hardware stores.
