How To Replace a Motor on an LG Dishwasher

Replacing the motor in your LG dishwasher might seem daunting, but with the right tools and a methodical approach, it's a manageable DIY repair. This guide will walk you through the process, saving you the cost of a professional repair. Always remember to disconnect the power supply before starting any repair work.

Assessing the Situation: Is it Really the Motor?

Before diving into the replacement, it's crucial to confirm the motor is the culprit. Symptoms of a faulty motor include:

• Dishwasher won't start: The most obvious sign. Check the power supply and other components first, though.
• Strange noises: Grinding, humming, or clicking sounds during operation could indicate motor problems.
• Dishwasher runs but doesn't drain or wash: A malfunctioning motor might impede the pump's ability to drain or circulate water.
• Burning smell: This is a serious indicator and requires immediate action. Never operate the dishwasher if you smell burning.

If you've checked other potential problems (like a blown fuse, faulty circuit breaker, or clogged drain), and the symptoms persist, then a faulty motor is a likely suspect.

Tools You'll Need

Before you begin, gather the following tools:

• Screwdrivers: Phillips and flathead, various sizes.
• Pliers: Needle-nose and regular.
• Socket wrench set: Useful for removing stubborn screws.
• Multimeter: To test the motor's continuity (optional, but recommended).
• New LG Dishwasher Motor: Ensure you purchase the correct replacement motor for your specific LG dishwasher model. Always check your model number before ordering.
• Work gloves: To protect your hands.
• Safety glasses: To protect your eyes from debris.

Step-by-Step Guide to Replacing the LG Dishwasher Motor

This guide provides a general overview. Specific steps may vary slightly depending on your LG dishwasher model. Always refer to your dishwasher's service manual for model-specific instructions.

Step 1: Accessing the Motor

1. Disconnect power: Unplug the dishwasher from the power outlet.
2. Turn off the water supply: Shut off both the hot and cold water supply lines to the dishwasher.
3. Remove the access panel: Depending on your model, this might involve removing the bottom access panel, side panels, or even the entire front panel. Consult your service manual for the precise location of the motor and how to access it. Usually, this involves removing screws and carefully detaching clips.

Step 2: Removing the Old Motor

1. Disconnect wires: Carefully disconnect the electrical wires connected to the motor. Take pictures or make notes to ensure correct reconnection.
2. Detach the motor: The motor might be secured by screws, clips, or a combination of both. Carefully loosen and remove the fasteners holding it in place.
3. Remove the motor: Carefully remove the old motor from its housing. Take note of its position and orientation.

Step 3: Installing the New Motor

1. Position the new motor: Carefully place the new motor into its housing, ensuring it's correctly aligned.
2. Secure the new motor: Tighten the screws or clips that secure the motor in place.
3. Reconnect the wires: Connect the electrical wires to the new motor, referencing your pictures or notes. Ensure that the wires are securely connected to avoid short circuits.

Step 4: Reassembling the Dishwasher

1. Reassemble the panels: Carefully reassemble the access panels you removed in Step 1.
2. Reconnect the water supply: Turn the hot and cold water supply lines back on.
3. Reconnect the power: Plug the dishwasher back into the power outlet.

Step 5: Testing the New Motor

1. Run a test cycle: Run a short test cycle to verify that the new motor is functioning correctly.
2. Check for leaks: Inspect the dishwasher for any leaks after the test cycle.

Troubleshooting

If the dishwasher still doesn't work after replacing the motor, consider these possibilities:

• Incorrect wiring: Double-check the wiring connections.
• Faulty new motor: Contact the retailer or manufacturer to exchange the new motor.
• Other component failure: The problem might not be the motor.

Conclusion

Replacing a dishwasher motor is a challenging but achievable DIY task. By following these steps carefully and consulting your service manual, you can potentially save money and gain a valuable repair skill. Remember safety first – always disconnect the power before working on any appliance. If you are uncomfortable with any aspect of this repair, it's best to call a qualified appliance repair technician.
