Save Time And Money: How To Test Your Dishwasher Drain Pump At Home

A properly functioning drain pump is crucial for a seamless dishwasher experience. If your GE dishwasher is struggling to drain water, testing the drain pump is essential to pinpoint the cause of the issue. This comprehensive guide will provide you with step-by-step instructions on how to test a GE dishwasher drain pump, empowering you to diagnose and resolve the problem efficiently.

Safety First

Before embarking on any testing procedures, prioritize safety by unplugging your GE dishwasher from the power outlet. This simple measure will prevent any electrical hazards.

Required Tools

To successfully test your GE dishwasher drain pump, you will need the following tools:

• Multimeter
• Phillips head screwdriver
• Flashlight (optional)

Step-by-Step Testing Procedure

1. Access the Drain Pump

Locate the access panel at the bottom of your GE dishwasher and remove the screws using a Phillips head screwdriver. Carefully lift the panel to expose the drain pump assembly.

2. Disconnect the Drain Hose

Detach the drain hose from the drain pump by loosening the hose clamp with a screwdriver. Inspect the hose for any kinks or blockages. If necessary, clean the hose and reconnect it securely.

3. Remove the Drain Pump

Unscrew the bolts or screws holding the drain pump in place. Gently pull the drain pump out of the dishwasher.

4. Inspect the Drain Pump Impeller

Examine the impeller, located at the center of the drain pump, for any debris or damage. Remove any obstructions and ensure the impeller rotates freely without any resistance.

5. Check the Drain Pump Motor

Using a multimeter set to the ohms scale, test the continuity of the drain pump motor terminals. A reading of infinity indicates an open circuit, while a reading close to zero indicates a closed circuit. If the reading is infinity, the motor is likely faulty and needs to be replaced.

6. Test the Drain Pump Capacitor (Optional)

If the drain pump motor test passes, proceed to test the capacitor, if present. Disconnect the capacitor from the motor and set the multimeter to the capacitance scale. Measure the capacitance of the capacitor. A reading within 10% of the specified value indicates a functional capacitor. If the reading is significantly different, the capacitor needs to be replaced.

7. Reassemble the Dishwasher

Once all the components have been tested and confirmed to be in good condition, reassemble the dishwasher in reverse order. Tighten all the screws securely and reconnect the drain hose.

Troubleshooting Tips

• If the drain pump motor is faulty, replace it with a new one of the same model.
• If the drain pump capacitor is faulty, replace it with a new one with the same capacitance value.
• If the impeller is obstructed, clean it thoroughly and ensure it rotates freely.
• If the drain hose is kinked or blocked, clean or replace it as necessary.

Wrap-Up

Testing a GE dishwasher drain pump is a straightforward process that can help you diagnose and resolve drainage issues effectively. By following the steps outlined in this guide, you can ensure that your dishwasher drains water properly, leaving your dishes sparkling clean. Remember, if you encounter any difficulties or have additional questions, do not hesitate to consult a qualified appliance repair technician.
