How to Fix a KitchenAid Dishwasher That Isn’t Draining Properly

If you're experiencing drainage issues with your KitchenAid dishwasher, don't panic. This guide will walk you through several steps to troubleshoot and potentially resolve the problem.

1. Check the Drain Hose

Inspect for Kinks or Blockages

First, ensure that the drain hose is not kinked or blocked. A kinked hose can prevent proper drainage. Also, make sure the hose is properly connected and not pinched.

Correct Height

Ensure the drain hose is installed at the correct height, typically at least 20 inches above the floor, as per the manufacturer’s instructions.

2. Inspect the Filter and Drain Pump

Remove and Clean the Filter

Brush away any food particles and debris from the filter located at the bottom of the dishwasher. Clogged filters can prevent the dishwasher from draining.

Check the Drain Pump

Inspect the drain pump for any blockages. You may need to remove the pump cover to check it. Clear any debris that might be obstructing the pump.

3. Examine the Garbage Disposal

If your dishwasher is connected to a garbage disposal, run it to check if there are any clogs. Clearing the disposal might resolve the drainage issue.

4. Check the Air Gap

Inspect the Air Gap

For dishwashers with an air gap, remove the cap and clean any debris that might be blocking the air gap. This is a small device usually mounted on the sink.

5. Test the Drain Pump

If the above checks don't solve the issue, the drain pump may be faulty. Test the pump by running a cycle and listening for its operation. If it is silent or making unusual noises, it may need to be replaced.

6. Check the Control Board

Inspect the control board for any visible damage or burnt components. This board controls the operation of your dishwasher, and any issues here can cause drainage problems.

7. Reset the Dishwasher

Sometimes, a simple reset can resolve minor issues. Unplug the dishwasher for a few minutes or turn off the circuit breaker, then turn it back on.

8. Consult the Manual

Refer to your user manual for specific troubleshooting steps related to your model. Manufacturers often provide detailed guidance on how to address common issues.

9. Call a Professional

If none of the above steps resolves the issue, it might be time to call a professional technician for a more thorough diagnosis and repair.

By following these steps, you should be able to identify and potentially fix the drainage issue with your KitchenAid dishwasher. If the problem persists, it's always wise to consult a professional for assistance.
