A malfunctioning drain pump can lead to a dishwasher that fails to drain water, leaving dishes wet and potentially causing water damage. Testing the drain pump is a crucial step in troubleshooting dishwasher issues. Here’s a comprehensive guide on how to test an LG dishwasher drain pump:
Safety Precautions
Before starting, ensure the dishwasher is unplugged from the power source and the water supply is turned off. Wear gloves and safety glasses to protect yourself from potential electrical hazards and water splashes.
Identifying the Drain Pump
Locate the drain pump by removing the lower access panel at the bottom of the dishwasher. The pump is typically a small, cylindrical device connected to the drain hose.
Disconnect the Drain Pump
Disconnect the electrical wires connected to the drain pump. Use a multimeter to test for continuity between the pump terminals. If there is no continuity, the pump is faulty and needs to be replaced.
Remove the Drain Pump
Unscrew the bolts or clips holding the drain pump in place. Carefully pull out the pump, ensuring you do not damage the drain hose or other components.
Inspect the Drain Pump
Examine the drain pump for any visible damage, such as cracks or broken parts. Check the impeller for any obstructions or debris that may impede its rotation. Clean any debris or blockages found.
Test the Drain Pump Manually
With the pump removed, connect it directly to a power source using jumper wires. If the pump runs smoothly and drains water, it is likely functioning correctly. If the pump does not run or drain water, it is faulty and needs to be replaced.
Reinstall the Drain Pump
If the drain pump is confirmed to be faulty, replace it with a new one. Connect the electrical wires and reinstall the pump into the dishwasher. Secure it with bolts or clips.
Test the Dishwasher
Reconnect the water supply and plug in the dishwasher. Run a test cycle to ensure the drain pump is functioning correctly and the dishwasher is draining water properly.
Additional Troubleshooting Tips
- Check the drain hose for any kinks or blockages.
- Clean the drain filter to remove any debris or food particles.
- Ensure the dishwasher is leveled correctly, as an uneven surface can affect the pump’s performance.

- Purchase a new drain pump compatible with your LG dishwasher model.
- Disconnect the electrical wires and unscrew the bolts holding the old pump in place.
- Remove the old pump and install the new one.
- Connect the electrical wires and secure the pump with bolts.
