Quick fix: how to diagnose and repair a faulty kitchenaid dishwasher drain pump

Maintaining a functional dishwasher is crucial for keeping your kitchen clean and hygienic. One of the essential components of a dishwasher is the drain pump, responsible for expelling used water and food particles. If your KitchenAid dishwasher is not draining properly, a faulty drain pump could be the culprit. This comprehensive guide will provide you with step-by-step instructions on how to check your KitchenAid dishwasher drain pump.

Identifying the Drain Pump

1. Locate the access panel: Most KitchenAid dishwashers have an access panel at the bottom of the unit.
2. Remove the access panel: Use a screwdriver to remove the screws holding the panel in place.
3. Find the drain pump: The drain pump is typically located at the bottom of the dishwasher, near the back. It will be connected to the drain hose and have electrical wires attached to it.

Testing the Drain Pump

1. Unplug the dishwasher: For safety reasons, always unplug the dishwasher before performing any maintenance.
2. Disconnect the electrical wires: Carefully detach the electrical wires connected to the drain pump.
3. Use a multimeter: Set the multimeter to the ohms setting. Touch one probe to the negative terminal of the drain pump and the other probe to the positive terminal.
4. Check the resistance: A reading of 0 ohms indicates a short circuit, while a reading of infinity ohms indicates an open circuit. Both indicate a faulty drain pump.
5. Inspect the impeller: The impeller is the rotating part of the drain pump that pushes water out. Remove it and inspect it for damage or debris.

Troubleshooting Common Drain Pump Issues

Clogged drain hose: Disconnect the drain hose from the drain pump and check for any clogs or blockages.
Faulty drain pump: If the drain pump is not receiving power or has failed, it will need to be replaced.
Debris buildup: Over time, food particles and other debris can accumulate in the drain pump. Clean it regularly to prevent blockages.

Replacing the Drain Pump

1. Purchase a replacement drain pump: Ensure you get the correct model compatible with your KitchenAid dishwasher.
2. Disconnect the old drain pump: Remove the electrical wires and detach the drain hose from the old drain pump.
3. Install the new drain pump: Connect the new drain pump to the electrical wires and drain hose.
4. Test the dishwasher: Run a short cycle to ensure the new drain pump is functioning properly.

Tips for Maintaining Your Drain Pump

• Avoid putting large food particles or bones in the dishwasher.
• Use a dishwasher cleaner to remove grease and buildup.
