5 Simple Solutions for a Noisy Dishwasher

A noisy dishwasher can disrupt the calm of any household, indicating potential issues that need attention. What are your next steps? Start with the obvious.

A noisy dishwasher can disrupt the calm of any household, similar to a clothes dryer that isn’t heating, indicating potential issues that need attention. Just as a dryer might have a part failure or an underlying problem affecting its performance, dishwashers can exhibit issues that, if not addressed, may lead to further complications.

Underlying Causes of a Noisy Dishwasher

Obstructed Dishwasher Spray Arm

  • Problem: The spray arm in the dishwasher rotates and sprays water to clean the dishes. If it becomes obstructed by utensils or small dishes, it can create a rattling or banging noise.
  • Solution: Ensure the dishwasher is loaded correctly so that nothing obstructs the spray arms. Check for any debris that might have lodged in the spray arm itself and remove it to ensure it spins freely.

Worn Out Bearings in the Circulation Pump

  • Problem: The circulation pump uses bearings that can wear out over time, causing a grinding or groaning noise during operation.
  • Solution: Inspect the circulation pump for signs of wear and tear. If the pump’s bearings are damaged, replacing the pump is usually the most effective solution.

Loose Parts or Panels

  • Problem: Loose components, such as wash arm assemblies or access panels, can vibrate during the wash cycle, leading to unnecessary noise.
  • Solution: Tighten any loose screws on the spray arms, and check the fasteners on the access panels and internal components to ensure they are secure.

Hard Objects Caught in the Chopper Blade

  • Problem: Dishwashers have a chopper blade to break down food particles. Hard objects like bones or fruit pits can get caught in this blade, causing a loud noise.
  • Solution: Turn off and unplug the dishwasher, and then check and clear the chopper blade area. Be cautious; the blades can be sharp.

Improper Dishwasher Leveling

  • Problem: If the dishwasher is not level, it can cause it to operate more loudly than necessary.
  • Solution: Use a level to check the dishwasher’s alignment and adjust the feet to make sure it sits flat on the ground.

Preventive Maintenance for Quiet Operation

  • Routine Cleaning: Regularly clean the filter and spray arms to prevent debris build-up, which can contribute to noise and decrease efficiency.
  • Check Seals and Gaskets: Ensure that the door seals are intact and clean. Damaged or dirty seals can cause the dishwasher to work harder, which may increase noise levels.
  • Quality Detergent: Use high-quality dishwasher detergent and rinse aid to keep the appliance running smoothly and quietly.
