Diy dishwasher repair: a comprehensive guide to troubleshooting the drain pump

Is your KitchenAid dishwasher giving you trouble draining water? A faulty drain pump could be the culprit. Checking and replacing the drain pump is a relatively simple task that can save you the cost of a professional repair. Follow our step-by-step guide to learn how to check and replace a KitchenAid dishwasher drain pump.

Safety First

Before you begin, ensure your safety by unplugging the dishwasher from the power outlet and turning off the water supply.

Tools and Materials

• Screwdriver (Phillips or flathead, depending on your dishwasher model)
• Multimeter
• New drain pump (if needed)

Step 1: Locate the Drain Pump

The drain pump is usually located at the bottom of the dishwasher, behind the kickplate. Remove the kickplate by unscrewing the screws that hold it in place.

Step 2: Disconnect the Drain Hose

Detach the drain hose from the drain pump by loosening the hose clamp.

Step 3: Remove the Drain Pump

Unscrew the screws that hold the drain pump in place. Carefully remove the drain pump from the dishwasher.

Step 4: Test the Drain Pump

Using a Multimeter:

1. Set the multimeter to the resistance setting (Ω).
2. Touch one probe to each terminal on the drain pump.
3. A reading of 0-100 ohms indicates a good pump.
4. A reading of infinity (OL) indicates a faulty pump.

Using a Power Source:

1. Connect the drain pump to a power source (e.g., a 12V battery).
2. If the pump runs, it is in good condition.
3. If the pump does not run, it is faulty.

Step 5: Replace the Drain Pump

If the drain pump is faulty, you will need to replace it.

1. Remove the old drain pump gasket and clean the area where the gasket sits.
2. Install the new gasket and drain pump.
3. Tighten the screws that hold the drain pump in place.

Step 6: Reconnect the Drain Hose

Attach the drain hose to the drain pump and tighten the hose clamp.

Step 7: Reinstall the Kickplate

Replace the kickplate and screw it back into place.

Troubleshooting Tips

• If the drain pump is buzzing but not draining, check the impeller for debris or damage.
• If the drain pump is running but not draining, check the drain hose for kinks or blockages.
• If the drain pump is not running at all, check the electrical connections and replace the pump if necessary.
