Dishwasher Squealing During Wash Cycle

  • One of the most common reasons for a dishwasher to squeal during the wash cycle is due to a faulty motor. The motor may be worn out or have loose bearings, causing it to make a high-pitched noise.
  • A clogged spray arm can also cause a dishwasher to squeal during the wash cycle. If the spray arm is not able to rotate freely, it can create a loud noise as it tries to move.
  • A damaged pump or impeller can also be the culprit behind a squealing dishwasher. If there is damage to these components, they may not be able to function properly and can create an unpleasant noise during operation.
  • If the dishwasher’s water inlet valve is malfunctioning, it can cause a high-pitched sound during operation. This valve controls the flow of water into the dishwasher and if it’s not working correctly, it can create an irritating noise.
  • Another possible reason for a squealing dishwasher is due to loose or damaged parts within the unit. Loose screws or bolts can rattle around and create an annoying sound during operation.
