What To Know

  • A faulty drain valve can cause water to accumulate, leading to a growling noise.
  • Low water pressure can cause the pump to work harder, resulting in a growling noise.
  • By understanding the potential causes and implementing the solutions outlined in this guide, you can effectively address the growling issue in your dishwasher.

Dishwashers, the unsung heroes of our kitchens, can sometimes develop a peculiar problem: they start growling. This unexpected noise can be disconcerting, leaving you wondering, “Why is my dishwasher growling?” In this comprehensive guide, we’ll delve into the potential causes and provide practical solutions to restore peace and quiet to your kitchen.

The Culprits Behind Dishwasher Growling

  • Worn-out Pump: The pump is the heart of your dishwasher, responsible for circulating water throughout the appliance. Over time, the pump’s impeller (the rotating part) can wear down, causing it to make a growling noise.
  • Loose Spray Arm: The spray arm distributes water over the dishes. If it becomes loose or obstructed, it can vibrate and create a growling sound.
  • Damaged Bearings: Bearings support the rotating parts of the dishwasher, including the pump and spray arm. Worn-out bearings can cause these components to wobble, resulting in a growling noise.
  • Foreign Objects: Sometimes, small objects like silverware or food particles can get lodged in the dishwasher’s components, causing them to growl.
  • Malfunctioning Drain Valve: The drain valve opens and closes to drain water from the dishwasher. A faulty drain valve can cause water to accumulate, leading to a growling noise.

Troubleshooting and Solutions

  • Inspect the Pump: Remove the bottom panel of the dishwasher and check the pump for wear or damage. If the impeller is worn, it may need to be replaced.
  • Tighten the Spray Arm: Locate the spray arm and ensure it is tightly connected to the water supply. If it’s loose, tighten it using a wrench.
  • Lubricate Bearings: Apply a few drops of food-grade lubricant to the bearings of the pump and spray arm. This can reduce friction and eliminate growling noises.
  • Remove Foreign Objects: Check the filter and inside of the dishwasher for any foreign objects that may be causing the noise. Remove them and clean the dishwasher thoroughly.
  • Inspect the Drain Valve: Listen for any unusual noises coming from the drain valve. If it’s malfunctioning, it may need to be replaced.

Additional Tips

  • Use a Heavy-Duty Detergent: Dishwashers designed for heavy-duty cleaning cycles may produce more noise than those designed for lighter cycles.
  • Clean the Dishwasher Regularly: Regular cleaning helps prevent food buildup and other debris from accumulating, which can contribute to growling noises.
  • Avoid Overloading the Dishwasher: Overcrowding the dishwasher can strain the pump and other components, leading to noise.
  • Check the Water Pressure: Ensure that the water pressure to the dishwasher is adequate. Low water pressure can cause the pump to work harder, resulting in a growling noise.
  • Call a Professional: If you’re unable to resolve the growling noise on your own, don’t hesitate to contact a qualified appliance repair technician.

The Verdict: Restoring Dishwasher Harmony

By understanding the potential causes and implementing the solutions outlined in this guide, you can effectively address the growling issue in your dishwasher. Remember, regular maintenance and timely repairs can help prevent this problem from recurring and ensure that your dishwasher continues to operate smoothly and quietly.

What You Need to Learn

1. Why is my dishwasher making a growling noise only during certain cycles?
This could indicate a problem with the pump or spray arm, which may only be engaged during specific cycles.

2. Can I use WD-40 to lubricate the bearings?
No, WD-40 is not recommended for use on dishwasher bearings. Use a food-grade lubricant specifically designed for appliances.

3. How often should I clean my dishwasher?
It’s recommended to clean your dishwasher every 3-6 months to prevent buildup and ensure optimal performance.
