Why is My Citrus Heights Dishwasher Making Loud Sounds?
Diagnosing Noisy Dishwasher Problems in Citrus Heights, CA
If your dishwasher has recently become louder than usual — making grinding, buzzing, or rattling noises — it’s a sign something may be wrong. While some sound during operation is normal, excessive or new noise can indicate a mechanical or functional issue. Here’s what to check and when it’s time to get help from a professional.
Food or Debris in the Pump or Filter
Loose food particles or broken glass can get lodged in the pump or impeller blades, causing grinding or humming noises during wash and drain cycles.
Spray Arm Obstruction
If a spray arm is hitting dishes or a utensil has fallen through the rack, it can result in loud knocking or clunking sounds.
Worn Pump Bearings or Wash Motor
Over time, the wash motor or drain pump bearings can wear down, resulting in a loud humming, whining, or grinding noise.
Loose or Vibrating Parts
Loose screws, panels, or mounts can cause rattling or banging as the appliance runs. Even leveling legs that aren’t adjusted properly can contribute to excess vibration.
When to Call for Dishwasher Repair
If the noise seems mechanical, gets worse over time, or continues after a thorough cleaning and inspection, it’s time to bring in a technician. Persistent noise often points to failing internal components or water circulation issues that need expert attention.
