What To Know

  • The check valve is a one-way valve that allows water to flow out of the dishwasher but prevents it from flowing back in.
  • A malfunctioning check valve can result in water remaining in the dishwasher after a wash cycle.
  • Standing water in the bottom of the dishwasher, dishes not getting clean, and a foul odor are common signs of a clogged dishwasher drain.

A malfunctioning dishwasher can be a significant inconvenience in any household. When your KitchenAid dishwasher stops draining, it’s essential to take prompt action to prevent further damage and ensure your dishes are sparkling clean. This comprehensive guide will provide you with step-by-step instructions on how to fix a KitchenAid dishwasher not draining, empowering you to restore its functionality and keep your kitchen running smoothly.

Understanding the Drainage System

To effectively troubleshoot a dishwasher drainage issue, it’s crucial to understand how the system works. The drainage system comprises several components:

  • Drain pump: The pump forces water out of the dishwasher.
  • Drain hose: The hose connects the drain pump to the sink drain.
  • Air gap: This device prevents water from flowing back into the dishwasher.
  • Check valve: The valve allows water to flow out of the dishwasher but prevents it from flowing back in.

Troubleshooting Common Causes

1. Clogged Drain Hose

One of the most common causes of a dishwasher not draining is a clogged drain hose. Food particles, grease, and other debris can accumulate in the hose over time, obstructing the flow of water.

2. Faulty Drain Pump

The drain pump is responsible for expelling water from the dishwasher. A faulty pump can prevent the dishwasher from draining properly.

3. Air Gap Clog

The air gap is designed to prevent water from flowing back into the dishwasher. However, it can become clogged with food particles or grease, causing drainage issues.

4. Check Valve Malfunction

The check valve is a one-way valve that allows water to flow out of the dishwasher but prevents it from flowing back in. A malfunctioning check valve can result in water remaining in the dishwasher after a wash cycle.

Step-by-Step Repair Instructions

1. Check the Drain Hose

  • Disconnect the drain hose from the dishwasher and sink drain.
  • Inspect the hose for any kinks or clogs.
  • If the hose is clogged, use a drain snake or pliers to remove the blockage.

2. Test the Drain Pump

  • Unplug the dishwasher and turn off the water supply.
  • Remove the access panel at the bottom of the dishwasher.
  • Locate the drain pump and disconnect the wires.
  • Use a multimeter to test the continuity of the pump.
  • If the pump is faulty, replace it with a new one.

3. Clean the Air Gap

  • Locate the air gap on the countertop or sink.
  • Remove the cap and clean the inside with a small brush or toothpick.
  • Reinstall the cap and ensure it is securely tightened.

4. Replace the Check Valve

  • Disconnect the dishwasher from the water supply.
  • Remove the check valve from the drain hose.
  • Install a new check valve and tighten it securely.

Additional Tips

  • Regularly clean the dishwasher filter to prevent debris from clogging the drain.
  • Use a dishwasher cleaner to remove grease and buildup from the dishwasher’s interior.
  • Run the dishwasher on a hot water cycle to melt away any grease or food particles that may be clogging the drain.

Wrapping Up

Fixing a KitchenAid dishwasher not draining can be a straightforward task with the right tools and knowledge. By following the steps outlined in this guide, you can restore your dishwasher to optimal performance and ensure your dishes are sparkling clean. Remember to regularly maintain your dishwasher to prevent future drainage issues.
