Often there is a simple solution for a dishwasher not turning on, such as a loose wire. Other causes can be diagnosed with a multimeter and easily fixed by replacing the part.
To order a replacement part, you will need to know your dishwasher model. Consult your manual, or sometimes you will find model information on the exterior sides of the dishwasher or inside the dishwasher door.
Pro Tip: If taking the dishwasher apart, wear gloves to protect yourself from cuts, as the metal can be sharp.
Remember to unplug your dishwasher or switch off its power from inside your electrical panel before checking electrical components.
Dishwasher plugs can become dislodged due to the vibrations of the dishwasher or other kitchen appliances. A fuse can also blow inside the plug.
Some dishwashers are wired directly from the wall to the wires in the junction box. You can check the power supply by accessing the junction box underneath the dishwasher. Make sure the power is turned off from inside your electrical panel before testing with a multimeter.
Some models require an additional wall switch to the dishwasher power switch to be turned on. Often this switch is found next to the garbage disposal or kitchen light switches.
Once you have confirmed that the power connection is not at fault, check to see if a circuit breaker has been tripped.
Most dishwashers will not power up if the dishwasher door is not closed properly. If the door is not closing correctly, you may need to unscrew the panel around it to check the part.
If the latch is latching correctly, the door switch may have an electrical fault. The door switch allows power to the dishwasher only if the door is properly closed. Sometimes the door switch will come loose, or water can get in and damage it.
The wiring or cable harness consists of various wires that connect to various parts of the dishwasher. On most models, the wiring harness can be found with the control panel. Excess heat sometimes damages the wiring harness, or wires can melt and attach to the dishwasher.
Solving the dishwasher’s power problem could be as simple as examining the control board.
It is difficult to test the control board, so it is best checked by a professional. If you are unsure, it would be wise to check all the steps on this list before replacing the control board.
A fault with your dishwasher controls is most commonly found when some buttons work but others don’t. Make sure the dishwasher is disconnected from the power before proceeding.
Dishwashers with manual timers sometimes stop powering up because of a faulty timer.
The thermal fuse is a safety device that shuts off power to the control panel if the dishwasher overheats. On most models, the thermal fuse is in the control panel area. However, on other models, it may be located near the bottom of the tank.
