Why Is My Dishwasher So Loud All of a Sudden?

Ready to get peace and quiet back in your house? Follow these tips to learn how to silence a noisy dishwasher.

1. Dishwasher Is Overloaded

If your dishwasher is overloaded with dishes, it will have to work harder to clean them, and dishes are more likely to bang against each other. This can cause the dishwasher to run louder than normal. To fix this issue, simply don’t overload your dishwasher. Make sure you only put in as many dishes as the manufacturer recommends.

2. Spray Arm Is Blocked

If the spray arm of your dishwasher is blocked, it will not be able to rotate properly and will leave you with a dishwasher making loud noise. This can cause the dishwasher noise levels to go way up. To fix this issue, check the spray arm for any blockages and clean it if necessary.

3. Water Inlet Valve Issue

If the water inlet valve is not working properly, it can cause the dishwasher to make a buzzing or whistling sound when the water fills up. If your dishwasher sounds weird, this is likely the problem. You will likely need to get the inlet valve replaced by a professional.

4. Drain Pump Malfunction

If the drain pump of your dishwasher is not working properly, it can result in your dishwasher making noise like a buzzing, or grinding sound when the dishwasher starts draining at the end of a wash cycle. If this valve gets stuck, it can also result in your dishwasher not draining well.

5. Noisy Dishwasher Impeller

The impeller is responsible for moving the water around in your dishwasher. If this part is damaged or worn, it can cause the dishwasher to make a loud humming sound or a squealing noise. To fix this issue, you will likely need to replace the impeller. It’s possible to do this on some dishwashers without much expertise, but others will require the assistance of a professional. Check your manual to find out.
