Dishwasher Repair

The dishwashers drain pump can become clogged with debris or wear out resulting in noisy operation. You can try cleaning out any debris or replace the pump altogether.

Over time, the bearings inside the circulation pump can fail, creating a continuous droning sound when the appliance is running. If this happens, the entire circulation pump assembly will need to be replaced.

The water inlet valve opens to allow water to enter the dishwasher at various times during operation. The diaphragm inside the valve could deteriorate and deform over time. When this happens, the water passing through the diaphragm can produce a loud buzzing or squealing sound. Replacing the inlet valve with a new one should eliminate the noise.

The circulation pump motor uses an impeller to force water up through the wash arms. Noise can be caused by a broken impeller fin or by a damaged impeller scraping against the pump housing. Depending on your model, you may be able to replace the impeller independently of the motor.

Some dishwasher models use a heating element to dry the dishes. Over time, the element can fail. You can use a multi-meter to test the element for continuity a continuous electrical path present in the part. If the element tests negative for continuity, you will need to replace it with a new one.

This problem can be encountered with nearly any appliance. It may be a result of a short, burnt fuse or damaged circuitry.

Models, using a heating element, will have a limit switch that will shut off power to the element if the component gets too hot. If the switch fails, the heating element may not get any power at all again. You can use a multi-meter to test the switch for continuity.

Depending on the dishwasher model, the dispenser may have a number of components that can potentially fail, including a spring, lever, or actuator.

Since dispenser components cannot always be replaced individually, you will often have to replace the entire dispenser assembly itself.

This is usually an issue with the burner itself, the receptacle, or the switch. A great way to troubleshoot whether it’s a faulty burner or a power issue is by turning another burner on to see if it works. If none of your burners are working, it’s an issue with your power source. Our team can help pinpoint the source of the problem.

If your dishwasher has a main control board instead of a timer, the board can fail in the same way. While neither a timer nor control board can be easily tested, you can inspect both for signs of burning or a shorted out component.
