Dishwasher is Noisy

Excessive noise is one of the most common problems a dishwasher can experience. There are a few parts that can become damaged and become noisy. That’s where this guide comes in - you can use the information below to diagnose your problem, check the parts that could be giving you trouble, and find links to buy the replacement parts you need to make the fix yourself!

Dishwasher Pump

The dishwasher pump is typically responsible for pressurizing the spray arms and draining water from the appliance. When these parts become worn or damaged, they can become noisy. Commonly, there are two impellers driven by a motor that can be a source of excessive noise. 

Note: To troubleshoot a dishwasher pump you must handle electrical components. You must disconnect your washer before you do this. We recommend enlisting the help of an experienced professional before attempting to troubleshoot your motor. 

How to Troubleshoot a Dishwasher Pump:

Note: this process requires a multimeter 

1. Disconnect the dishwasher from its power source.
2. Locate and remove the dishwasher pump - it can typically be found behind the lower access panel. 
3. Use the multimeter on the RX1 setting to test the dishwasher pump. Place the probes on the terminals to test for continuity. Look to receive a reading of zero or close to zero.
4. Use the multimeter on the RX1 setting to test the dishwasher pump’s ground connection. Touch one probe to the terminal and one to the metal exterior of the pump. You should not receive any reading.
5. If you receive different results from your tests than those listed above, you must replace your dishwasher pump.

Don’t forget: just because parts look the same does not mean that they are the same. Make sure to use cross reference information and model numbers to confirm compatibility with your dishwasher.

Spray Arms

The spray arms work with the pump to shoot water and detergent around the dishwasher. Some dishwashers have both a top and bottom spray arms. All dishwashers have a bottom spray arm. If the spray arm is damaged, worn, or loose and wobbly, then it may become noisy during the operation of the dishwasher. 

How to Troubleshoot a Dishwasher Spray Arm:

1. Disconnect the dishwasher from its power source.
2. Try to spin the spray arms manually - they should spin freely, and they should not wobble.
3. Inspect the spray arms for any signs of visible damage like cracking.
4. If you encounter any of these problems while inspecting your spray arm, you must replace it.

Don’t forget: just because parts look the same does not mean that they are the same. Make sure to use cross reference information and model numbers to confirm compatibility with your dishwasher.
