Why is my kitchenaid dishwasher playing hide-and-seek with draining?

When your KitchenAid dishwasher refuses to drain, it can leave you with a sink full of dirty dishes and a frustrating enigma to solve. Understanding the underlying causes of this issue is crucial for restoring your dishwasher to its optimal functionality. In this comprehensive guide, we will delve into the labyrinth of potential reasons why your KitchenAid dishwasher is not draining and provide practical solutions to resolve each problem.

Clogged Drain Hose

A blocked drain hose is a common culprit behind dishwasher drainage issues. Debris, food particles, and grease can accumulate in the hose, obstructing the flow of water. To inspect the drain hose, detach it from the dishwasher and check for any visible blockages. If you find any, remove them using a wire or pipe cleaner.

Faulty Drain Pump

The drain pump is responsible for expelling water from the dishwasher. If the pump fails, the dishwasher will not be able to drain properly. To test the drain pump, listen for a humming sound when the dishwasher is in the drain cycle. If you don’t hear any sound, the pump may be faulty and require replacement.

Clogged Drain Filter

The drain filter traps food particles and other debris to prevent them from entering the drain hose. Over time, the filter can become clogged, impeding the flow of water. To clean the drain filter, locate it at the bottom of the dishwasher tub and remove it. Rinse the filter thoroughly with water and reinstall it.

Blocked Air Gap

The air gap is a small device installed between the dishwasher and the sink drain to prevent backflow of water into the dishwasher. If the air gap becomes blocked, it can create a vacuum that prevents the dishwasher from draining. To check the air gap, remove the cover and inspect it for any debris or blockages.

Kinked Drain Hose

A kinked drain hose can restrict the flow of water and cause drainage problems. Ensure that the drain hose is not bent or twisted in any way. Straighten out any kinks and make sure the hose is properly connected to the dishwasher and the sink drain.

Faulty Control Board

The control board is the brain of the dishwasher and manages its various functions, including draining. If the control board malfunctions, it may send incorrect signals to the drain pump or other components, resulting in drainage issues. Troubleshooting the control board requires specialized knowledge and may involve replacing it.

Resetting the Dishwasher

Sometimes, a simple reset can resolve minor glitches that may be causing drainage problems. To reset the dishwasher, turn off the power at the circuit breaker or fuse box, wait a few minutes, and then turn it back on. This will reset the dishwasher’s control board and may restore its normal functionality.

Final Thoughts:

Understanding the reasons why your KitchenAid dishwasher won’t drain is essential for effective troubleshooting and repair. By following the steps outlined in this guide, you can diagnose the issue and implement the appropriate solution to restore your dishwasher to its pristine condition. Remember, if the problem persists or you encounter any complexities, do not hesitate to contact a qualified appliance repair technician for assistance.
