Dishwasher Noise: Why Is It Growling and How to Fix It for Good

When your dishwasher should be quietly cleaning your dishes, but instead, it’s growling like a hungry beast, it’s time to investigate. A growling dishwasher can be an annoying and potentially costly problem. In this comprehensive guide, we’ll explore the various reasons why your dishwasher might be making a growling noise and provide solutions to help you restore peace and quiet to your kitchen.

What Causes a Dishwasher to Growl?

The growling noise in your dishwasher is likely caused by one or more of the following issues:

• Worn-Out Pump: The pump is responsible for circulating water through the dishwasher. Over time, the pump can wear out, causing it to make a growling or grinding noise.
• Clogged Drain: A clogged drain can prevent water from draining properly, which can cause the pump to work harder and make a growling noise.
• Loose or Damaged Spray Arms: The spray arms rotate to spray water on the dishes. If they are loose or damaged, they can hit against the dishes or other components, causing a growling noise.
• Foreign Objects: Sometimes, small objects like bottle caps or silverware can get stuck in the dishwasher and cause a growling noise as they are circulated by the water.
• Faulty Motor: The motor is responsible for powering the dishwasher. If the motor is faulty, it can cause the dishwasher to make a growling noise.
• Damaged Bearings: The bearings support the rotating parts of the dishwasher. If they are damaged, they can cause a growling noise.
• Air Pockets in the Water Line: Air pockets in the water line can cause the pump to work harder and make a growling noise.

How to Fix a Growling Dishwasher

Depending on the cause of the growling noise, there are several steps you can take to fix the problem:

• Clean the Drain: Remove any food particles or debris from the drain filter and check for any clogs in the drain hose.
• Tighten or Replace Spray Arms: Make sure the spray arms are securely attached to the dishwasher. If they are damaged, replace them with new ones.
• Remove Foreign Objects: Check the dishwasher for any small objects that may have gotten stuck. Remove them and restart the dishwasher.
• Call a Repair Technician: If the growling noise persists after trying the above steps, it’s best to call a qualified repair technician to diagnose and fix the problem.

Preventing Dishwasher Growling

To prevent your dishwasher from growling in the future, follow these tips:

• Rinse Dishes Before Loading: Rinse dishes to remove food particles before loading them into the dishwasher.
• Clean the Dishwasher Regularly: Run a hot water cycle with a dishwasher cleaner once a month to remove any buildup or debris.
• Use High-Quality Dishwasher Detergent: Cheap dishwasher detergent can leave residue that can clog the dishwasher and cause growling.
• Don’t Overload the Dishwasher: Overloading the dishwasher can prevent dishes from getting properly cleaned and can cause the spray arms to hit against them.
• Check the Water Pressure: Make sure the water pressure to your dishwasher is sufficient. Low water pressure can cause the pump to work harder and make a growling noise.

Troubleshooting Dishwasher Growling

If you’re still having trouble with a growling dishwasher, try the following troubleshooting tips:

• Run a Diagnostic Cycle: Many modern dishwashers have a diagnostic cycle that can help identify the source of the growling noise.
• Check the Impeller: The impeller is a small blade that helps circulate water in the dishwasher. If it is damaged or clogged, it can cause a growling noise.
• Inspect the Door Seal: The door seal prevents water from leaking out of the dishwasher. If it is damaged, it can cause the dishwasher to make a growling noise as it tries to seal the door.
