Dishwasher Noise
Cause
How to Fix
1. Dishwasher Making Loud Noise When Running
This is one of the most common complaints and is often caused by mechanical issues or loose components.
Cause: Loose components or a faulty circulation pump.
How to Fix:
-
Check for loose screws or items in the spray arms. Tighten or reposition them as needed.
-
Inspect the circulation pump for damage, such as worn-out bearings or broken impellers. Replace it if necessary.
2. Dishwasher Making Loud Grinding Noise
A loud grinding or crunching sound usually happens when food particles or debris are stuck in the pump or motor, causing friction.
Cause: Food debris stuck in the pump or a malfunctioning motor.
How to Fix:
- Turn off the dishwasher and remove the bottom rack.
- Clean out any visible debris near the pump.
- If grinding persists, the motor or pump impeller may need replacement.
3. Dishwasher Making Loud Noise When Draining
If you hear a loud noise when the dishwasher is draining, it’s often a sign that the water isn’t flowing freely through the system.
Cause: Clogged drain pump or hose.
How to Fix:
- Remove and clean the drain pump and hose.
- Check for blockages in the garbage disposal or sink connection.
4. Dishwasher Making Loud Noise When Starting
A loud noise at the beginning of the cycle could signal a problem with the water inlet valve or an issue with the motor starting up.
Cause: Faulty water inlet valve or noisy motor startup.
How to Fix:
- Inspect the water inlet valve for damage and replace it if necessary.
- If the motor makes excessive noise, it may need professional servicing.
5. Dishwasher Making Loud Humming Noise
A constant humming sound often points to an obstruction or malfunction in the motor or impeller.
Cause: A jammed motor or impeller.
How to Fix:
- Turn off the dishwasher and check for blockages in the impeller.
- Free up any jams and test the motor.
6. Dishwasher Making Noise When Off
If your dishwasher makes noise even when it’s turned off, you might notice a water hammer sound or a low buzzing when it’s not in operation.
Cause: Water hammer effect or a malfunctioning solenoid valve.
How to Fix:
- Check the water supply line for pressure issues.
- Replace the solenoid valve if it’s causing noise when the dishwasher isn’t running.
7. Dishwasher Making Loud Noise During Wash Cycle
If the noise is only present during the wash cycle, it could indicate a problem with the spray arm bearings or the circulation system.
Cause: Worn spray arm bearings or broken components in the circulation system.
How to Fix:
- Inspect and replace damaged spray arms or bearings.
- Clean and lubricate the moving parts in the circulation system.
8. Dishwasher Pump Making Loud Noise

Cause: Pump failure or obstruction.
How to Fix:
- Inspect the pump for visible damage.
- Remove any blockages and replace the pump if necessary.
9. Dishwasher Door Making Loud Noise
A loud noise when opening or closing the dishwasher door is often caused by worn hinges or a faulty door latch.
