How to Fix a Dishwasher That Won’t Start

Dishwasher Won't Start - Dishwasher Repair - It Is Fixed - Atlanta

Have you just loaded the dishwasher only to find out that it won’t start? Don’t rush out to buy a new dishwasher. Repairing your appliance almost always saves money over buying a new appliance. There are a few steps you can take to troubleshoot the issue.

Here are seven things to check when your dishwasher won’t start:

Check the Power Outlet
If the appliance is showing no signs of life, the first thing to do is make sure that the dishwasher is receiving power. If there are no lights or sounds, ensure the plug is pushed firmly into the power outlet.  Next, reset the power outlet by turning the power off and back on at the circuit breaker.

Inspect The Door Latch
If the dishwasher fails to start the problem could lie in the door latch assembly. In most dishwasher models the door latch assembly is located behind the inner rear panel. The door latch holds the door close and prevents water from seeping out during a cycle. Typically, if the latch is damaged the dishwasher will not start. In addition, the door switch is also located in the door latch assembly. The switch supplies power to the dishwasher control. Therefore, when the latch assembly is defective and the door is unable to fully close the control buttons don’t receive any power.

Check for a Faulty Timer or Electronic Control
Does your dishwasher utilize a manual timer or electronic control function? The click of the timer indicates that power is being supplied to each cycle of the sequence. The first step in the cycle is the drain function which removes the standing water in the basin or tub at the bottom of the dishwasher. Check to see if you hear the drain pump motor running then the manual timer or electronic control could be why the appliance isn’t starting. The timer function controls all the electro-mechanical capabilities of the appliance. When it’s defective it can ultimately prevent all the components from working.

In the newer model dishwashers, a fault code is displayed when there are faults in the timer controls. Owners can check the owner’s manual to translate these codes.

Replace the Thermal Fuse
If the dishwasher is plugged in but not receiving power, the thermal fuse may need to be replaced. These electronic appliances are controlled by a thermal fuse that protects the control board. Depending on the model, certain components will still operate with a blown or damaged thermal fuse yet the wash cycle won’t initiate. You can check yourself to see if the fuse is blown by removing the inner panel door to access the control panel where the thermal fuse is located.

Warning: Unplug the dishwasher before attempting to check or replace the thermal fuse.

Replace the Drive Motor
The drive motor is an essential component in a dishwasher. The drive motor is what circulates the water during the wash cycle and gets the dishes clean. In order for the drive motor to work it needs to be powered electrically through the timer and the start relay. When the relay doesn’t have enough power to feed the drive motor this is a big indication of a defective motor. A loud humming noise is a sign that the motor is seized. In this case, the motor needs to be switched out with a new one.

Power Supply Board or Control Panel
Some dishwasher models are equipped with a secondary supply control board which can interfere with the main control board. When this control board begins to malfunction it will inhibit the power that’s supposed to be delivered to the primary power board.

Depending on how long you’ve had your dishwasher, over time the control panel can become damaged or even loose due to constant use. Inspect the control panel for frayed wires, stuck buttons and other signs of wear. In some cases, simply replacing the control panel can get the appliance up and running again.

There are numerous possible reasons why the dishwasher won’t start. Troubleshooting can help you diagnose common issues but sometimes professional help is necessary.
