Your dishwasher is a hero in the kitchen. It saves you from the monotonous and sometimes unrewarding work of washing dishes by hand, allowing you to spend quality time with your family and friends.
Dishwasher Is Making a Loud Noise
If your dishwasher is making a loud noise, here are the most probable causes:
Defective drain pump
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.
Malfunctioning circulation pump
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.
Worn water inlet valve
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.
Dishwasher Is Not Drying Dishes
If your dishwasher is not drying the dishes properly, here are the most probable causes:
Malfunctioning heating element
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.
Damaged vent assembly
Many dishwashers will use a vent assembly with a motorized door to let out the hot steamy air generated during the rinse cycle. If the vent does not open all the way, the moisture cannot escape and will be left on the dishes. A warped or damaged vent will need to be replaced.
Defective vent fan motor
Some models use a vent fan motor to blow the heated air out through the vent following the rinse cycle. If the fan blade is damaged, or the motor itself is defective, the dishes won’t dry properly. As with the heating element, you can use a multi-meter to test the motor for continuity. If the motor tests negative for continuity, you will need to replace it with the new one.
Defective limit switch
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.
Dishwasher Dispenser Is Not Working
If your dishwasher’s detergent dispenser is not working, here are the most probable causes:
Malfunctioning dispenser component
Depending on the dishwasher model, the dispenser may have a number of components that can potentially fail, including a spring, lever, or actuator.
Defective detergent dispenser
Since dispenser components cannot always be replaced individually, you will often have to replace the entire dispenser assembly itself.
Some dishwasher models use a timer, which provides power to nearly every dishwasher component. A faulty timer may fail to open the dispenser.
Faulty main control board
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.
