Dishwashers are a modern marvel, effortlessly washing away the remnants of our meals. However, sometimes these appliances can develop an unexpected issue – a persistent growling or rattling noise. If you’re facing this perplexing problem, you’re not alone. In this blog post, we’ll delve into the possible causes of a growling dishwasher and provide practical solutions to restore peace and quiet to your kitchen.
Clogged Spray Arms
One of the most common culprits behind a growling dishwasher is clogged spray arms. These arms rotate during the wash cycle, spraying water onto the dishes. If the holes in the spray arms become blocked with food particles or debris, the water flow can be restricted, creating a rattling or growling sound.
Worn or Loose Impeller
The impeller is a vital component of the dishwasher’s wash pump. It generates the water pressure needed to rotate the spray arms. Over time, the impeller can become worn or loose, causing it to vibrate and produce a growling noise.
Malfunctioning Drain Pump
The drain pump is responsible for draining water from the dishwasher after the wash cycle. If the drain pump fails or becomes blocked, water can accumulate in the dishwasher, causing it to growl or rattle.
Worn or Broken Motor Mounts
The dishwasher’s motor is mounted on rubber or plastic mounts to reduce vibration. However, these mounts can deteriorate over time, allowing the motor to move and create a growling sound.
Overloaded Dishwasher
An overloaded dishwasher can put strain on the motor and other components, leading to a growling noise. Avoid overloading the dishwasher and ensure that dishes are properly spaced to allow for efficient water flow.
Improperly Installed Dishwasher
If the dishwasher is not properly installed, it can cause it to vibrate excessively and produce a growling sound. Make sure the dishwasher is level and securely fastened to the cabinetry.
Faulty Control Board
The control board is the brain of the dishwasher, controlling all its functions. A faulty control board can send incorrect signals to the other components, causing the dishwasher to growl or rattle.
Troubleshooting Tips
Before calling a professional, there are a few simple troubleshooting steps you can try:
- Clean the spray arms: Remove the spray arms and clean the holes with a toothpick or pipe cleaner.
- Check the drain pump: Inspect the drain pump for any blockages or obstructions.
- Tighten the motor mounts: If the motor mounts are loose, tighten them using a screwdriver or wrench.
- Level the dishwasher: Adjust the dishwasher’s feet to ensure it is level and stable.
- Restart the dishwasher: Sometimes, a simple reset can resolve the issue.
When to Call a Professional
If the troubleshooting steps above do not resolve the growling noise, it’s best to call a qualified appliance repair technician. They can diagnose the underlying problem and perform the necessary repairs to restore your dishwasher to its quiet operation.
