A KitchenAid dishwasher making loud noise can disrupt the peaceful atmosphere in your home and leave you wondering what to do if your dishwasher is making a loud noise. Before calling a professional, you can troubleshoot and fix some common issues on your own. Check out these different reasons why a KitchenAid dishwasher might be loud all of a sudden and provide helpful tips for silencing the noise.
How to Silence a KitchenAid Dishwasher Making Loud Noise
Even so-called “quiet” dishwashers make some sounds while running that are normal. Other noises can be a sign of a problem. Here’s what to look for when your KitchenAid dishwasher makes noise.
Dishwasher Not Loaded Correctly
One of the simplest reasons for a noisy KitchenAid dishwasher is improper loading. Overloading your dishwasher with too many items can cause dishes to bang together, creating a loud clattering sound. Similarly, dishes blocking the spray arm can lead to a KitchenAid dishwasher making loud noise.
To fix this issue, make sure to:
- Avoid overloading your dishwasher.
- Place dishes strategically so they don’t bang against each other during the cycle.
- Ensure the spray arm can rotate freely without any obstruction.
Water Supply Noises
Water supply issues can cause a KitchenAid dishwasher to make buzzing sounds. If the water supply is turned off or there’s a kinked inlet hose, your dishwasher may struggle to fill, creating a loud humming noise. If left unchecked, your dishwasher could start leaking as well.
To resolve water supply issues:
- Make sure the water supply valve is open.
- Check the inlet hose for kinks and straighten it if necessary.
- If you suspect a water inlet valve malfunction, consider contacting a professional for replacement.
Obstructed Drain Pump
An obstructed drain pump can result in a KitchenAid dishwasher making a grinding noise. Food particles and debris can get stuck in the drain filter and the pump itself, leading to obstructions.
To clean the drain filter and remove pump obstructions:
- Turn off and unplug your dishwasher.
- Remove the bottom rack and locate the drain filter (usually at the base of the dishwasher).
- Take out the filter and clean it with a soft brush and warm, soapy water.
- Inspect the drain pump for obstructions, and if possible, remove any debris.
Clogged or Damaged Spray Arm
A clogged or damaged spray arm can be another reason why your KitchenAid dishwasher makes a humming noise. Cleaning the spray arm ports and inspecting it for damage can help resolve this issue and even boost cleaning performance.
To remove and clean the spray arm:
- Turn off and unplug your dishwasher.
- Remove the bottom rack to access the spray arm.
- Detach the spray arm by following the manufacturer’s instructions.
- Clean the ports using a toothpick, pipe cleaner, or a small brush.
- Inspect the spray arm for damage and replace it if necessary.
Faulty Dishwasher Components
If you’ve tried all the above solutions but your KitchenAid dishwasher is still making loud noise, it’s possible that one or more of its components are faulty. The drain pump, circulation pump, and fan motor are a few parts that can cause noise when they malfunction.
In such cases, it’s best to contact a professional appliance repair service like Advance Appliance Service to diagnose and fix the problem.
