Reasons for Dishwasher Noise
Here are the common reasons why your dishwasher is making noise:
- Damaged or Worn Out Wash Arm Bearing Ring
- Dirty or Clogged Spray Arm
- Malfunctioning Water Inlet Valve
- Faulty Motor Bushing
- Worn Out Pump Seal
Damaged or Worn Out Wash Arm Bearing Ring
The wash arm bearing ring is responsible for holding the wash arm in place. It is a plastic ring that can wear out or become damaged over time. When this happens, the wash arm can wobble and make noise during its operation.
Dirty or Clogged Spray Arm
The spray arm is responsible for distributing water evenly during the wash cycle. Over time, it can become dirty or clogged with food particles, soap scum, and other debris. This can cause the spray arm to vibrate, producing noise during its operation.
Malfunctioning Water Inlet Valve
The water inlet valve is responsible for regulating the flow of water into the dishwasher. When it malfunctions, it can cause a loud humming or vibrating noise during its operation.
Faulty Motor Bushing
The motor bushing is a small rubber gasket that helps to reduce vibration and noise during the motor’s operation. When it becomes worn out, it can cause the motor to vibrate, producing noise during the wash cycle.
Worn Out Pump Seal
The pump seal is responsible for preventing water from leaking out of the dishwasher’s motor. When it becomes worn out, it can cause water to leak out and produce noise during the wash cycle.
Troubleshooting Dishwasher Noise
Here are the steps to troubleshoot dishwasher noise:
- Inspect the Wash Arm Bearing Ring
- Clean the Spray Arm
- Check the Water Inlet Valve
- Test the Motor Bushing
- Inspect the Pump Seal
Inspect the Wash Arm Bearing Ring
To inspect the wash arm bearing ring, remove the lower dish rack and locate the wash arm at the bottom of the dishwasher. Gently wiggle the wash arm to see if it is loose or wobbly. If it is, remove the wash arm and inspect the bearing ring for damage. If it is damaged, replace it with a new one.
Clean the Spray Arm
To clean the spray arm, remove it from the dishwasher and soak it in warm, soapy water for 15-20 minutes. Use a soft brush or toothbrush to remove any debris or buildup. Rinse the spray arm thoroughly and reattach it to the dishwasher. Test the dishwasher to see if the noise has stopped.
Check the Water Inlet Valve
To check the water inlet valve, turn off the dishwasher’s power supply and water supply. Locate the water inlet valve at the bottom of the dishwasher and inspect it for any signs of damage or wear. If it appears to be damaged, replace it with a new one.
Test the Motor Bushing
To test the motor bushing, turn off the dishwasher’s power supply and remove the lower dish rack. Locate the motor at the bottom of the dishwasher and gently wiggle it to see if it is loose. If it is, inspect the motor bushing for any signs of wear or damage. If it is worn out, replace it with a new one.
Inspect the Pump Seal
To inspect the pump seal, turn off the dishwasher’s power supply and water supply. Locate the pump at the bottom of the dishwasher and inspect it for any signs of water leakage. If there is water leakage, the pump seal is likely worn out and needs to be replaced.
