A KitchenAid dishwasher is essential for maintaining efficiency in any commercial kitchen. when it stops draining, it can cause major disruptions. Many drainage issues arise from problems with the KitchenAid dishwasher parts such as the drain pump, hose, or filter. The good news is that most of these issues can be resolved quickly with some basic troubleshooting. In this guide, we'll walk you through the common causes behind drainage problems and how you can fix them, often by cleaning or replacing specific parts.

Step 1: Check and Clear the Drain Hose

The dishwasher cannot drain correctly when its drain hose becomes blocked or develops a kink. The drainage system fails because food debris and grease or buildup block the hose.

Steps to Fix:

  • For safety, switch off the dishwasher and disconnect it from the power source.
  • Locate the drain hose, typically found at the bottom of the dishwasher, which connects to your sink or drainage system.
  • Check the hose for any visible kinks, twists, or blockages. While a kinked hose can be straightened, a blockage will need to be cleared.
  • Disconnect the hose from the dishwasher and sink (you may need to loosen a clamp or screw to do this).
  • Clear any debris or buildup from the hose. Use a flexible brush or run warm water through the hose to flush out any obstructions.
  • Reattach the hose securely and test your dishwasher by running a short cycle to see if the issue is resolved.

Regular drain hose maintenance helps your dishwasher operate efficiently and stops future clogging issues.

Step 2: Clean the Dishwasher Filter

Problem: The filter serves to trap food particles so they do not reach the drain pump. The filter blockage prevents free water flow which leads to drainage problems.

Steps to Fix:

  • Remove the bottom rack to reach the dishwasher's filter.
  • Remove the filter by pulling it out of its compartment. It may have a mesh or grate design.
  • Inspect the filter for food particles, grease, or buildup.
  • Wash the filter using warm soapy water and a soft brush to remove any debris.
  • Reinstall the filter securely return it to place, and run a cycle to check drainage.

Step 3: Inspect the Drain Pump for Blockages

Problem: The drain pump is responsible for removing water from the dishwasher. If it's blocked or not functioning properly, the dishwasher will struggle to drain efficiently.

Steps to Fix:

  • Unplug the dishwasher for safety and remove the bottom panel (this may require a screwdriver).
  • Locate the drain pump, typically positioned at the dishwasher's bottom.
  • Check the pump for any visible debris, blockages, or objects that could be blocking it. A flashlight can help you get a better view of the area.
  • If debris is trapped, carefully remove it using a small brush or tweezers.
  • After clearing any debris, check the pump for signs of damage or wear. If the pump is cracked, corroded, or otherwise damaged, it will require replacement.
  • Reassemble the panel and run a test cycle to check if the dishwasher drains properly.

Step 4: Check the Garbage Disposal Connection

Problem: If your dishwasher is linked to a garbage disposal, a clogged disposal or drain may hinder proper drainage.

Steps to Fix:

  • Check the garbage disposal for any visible blockages. Run it to ensure it's functioning properly and draining well.
  • Inspect the drain hose connection between the dishwasher and the garbage disposal. Look for any blockages in the hose or where the hose connects to the disposal.
  • Clear out any obstructions in the disposal or hose to ensure proper drainage.
  • Run a quick cycle on your dishwasher to see if it drains properly.

Step 5: Inspect and Clean the Float Switch

Problem: The float switch tracks the water level inside the dishwasher. If it's stuck or malfunctioning, the dishwasher may believe the water level is still too high and not drain as a result.

Steps to Fix:

  • Open the dishwasher door and find the float, typically located at the bottom of the tub.
  • Ensure that the float can move up and down If it's stuck or obstructed by debris, gently clean around the float with a soft brush or cloth.
  • Test the float by manually moving it up and down to ensure it functions smoothly.

Step 6: Check Valve: Prevent Backflow

Problem: The check valve stops contaminated water from re-entering the dishwasher after it has been drained. If this valve is damaged or obstructed, dirty water could flow back into the dishwasher.

Steps to Fix:

  • Locate the check valve near the drain pump or where the drain hose connects.
  • Examine the valve for any blockages or signs of damage. It should operate smoothly without any hindrance.
  • Clear any debris that may be blocking the valve.

Step 7: Ensure Proper Power Supply and Electrical Function

Problem: If your dishwasher is not draining, it could be an electrical issue preventing the drain cycle from activating.

Steps to Fix:

  • Inspect the power source: Make sure the dishwasher is securely plugged in and that the circuit breaker hasn't been tripped.
  • Test the control board: If the dishwasher is not responding to the drain cycle, the control board or timer may be faulty. This requires a more advanced inspection.
  • If the dishwasher still does not drain, consult a professional to inspect the electrical components.

Step 8: When to Replace KitchenAid Dishwasher Parts

Problem: If you've followed all the troubleshooting steps and your KitchenAid dishwasher continues to have drainage issues, it may be time to think about replacing specific parts. Parts such as the drain pump, float switch, check valve, or drain hose can wear out over time and affect the drainage system.

Steps to Fix:

  • Inspect the parts: After troubleshooting, if you notice that components Like the drain pump or float switch are damaged or malfunctioning, they may need replacement.
  • If troubleshooting doesn't fix the problem, it might be necessary to replace the parts. You can order authentic KitchenAid dishwasher parts from trusted suppliers like PartsFe to ensure proper functionality and reliable performance.
  • Replace the part yourself: If you're confident in handling DIY repairs, you can replace the faulty parts on your own. The process typically involves disconnecting the dishwasher, removing the damaged component, and installing the replacement part according to the provided instructions.
  • Call a professional technician: If you're unsure how to replace parts or prefer professional assistance, don't hesitate to call a technician to get the parts replaced properly.
