Lg Washing Machine Drain Motor Not Working

Introduction

Is your LG washing machine stubbornly refusing to drain water? A common culprit is a problem with the drain motor. When the drain motor isn’t working, the water stays put, leaving your clothes soaking wet. This is more than just an inconvenience; it can lead to mold growth, smelly laundry, and a potentially unusable washing machine. Addressing this issue promptly is crucial to prevent further damage and get your laundry routine back on track.

Common Causes of lg washing machine drain motor not working

Here are some common reasons why your LG washing machine’s drain motor might be failing:

Clogged Drain Hose: A blocked hose restricts water flow, preventing the motor from draining the water.
Clogged Drain Filter: The filter traps lint and debris, which can accumulate and block the drain.
Obstructed Drain Pump: Small items like socks or coins can get lodged in the pump, hindering its operation.
Faulty Drain Motor: The motor itself might be defective due to wear and tear or electrical issues.
Wiring Problems: Damaged or loose wiring can disrupt the power supply to the drain motor.
Defective Water Level Sensor: If the sensor malfunctions, it may not signal the motor to drain.
Control Board Issues: The control board sends signals to the drain motor. A faulty board can cause the motor not to activate.
Overloading the Washing Machine: Consistently overloading the machine can strain the drain motor, leading to premature failure.
Using Too Much Detergent: Excessive detergent can create suds that hinder draining.

Symptoms Checklist

Look for these signs to confirm if the drain motor is the problem:

Washing machine tub is full of water after the wash cycle.
You can hear a humming sound, but the water isn’t draining.
The washing machine displays an error code related to draining. (e.g., OE, DE, E2)
The drain hose is not blocked, but the water still won’t drain.
The washing machine cycle stops mid-wash and doesn’t proceed to drain.

How to Fix lg washing machine drain motor not working Step-by-Step Guide

Follow these steps to troubleshoot the issue:

Unplug the Washing Machine: For safety, disconnect the power cord from the outlet before you begin.
Check the Drain Hose: Detach the drain hose from the drainpipe and inspect for kinks or blockages. Straighten any kinks and clear any debris.
Clean the Drain Filter: Locate the drain filter (usually at the bottom front of the machine, behind a small access panel). Unscrew the cap, remove the filter, and clean it thoroughly under running water.
Inspect the Drain Pump: With the filter removed, use a flashlight to peek into the drain pump housing. Check for any visible obstructions like coins, buttons, or lint.
Manually Check the Pump Impeller: Carefully reach into the pump housing (with gloves) and try to rotate the impeller (the small fan-like part inside). If it’s stuck, try to gently dislodge the obstruction.
Check the Wiring: Locate the drain motor (refer to your washing machine’s manual for its location). Inspect the wiring connections to the motor. Make sure the wires are securely connected and not damaged.
Test the Water Level Sensor: The water level sensor indicates the water level to the control board. If faulty, it may cause draining issues. Consult your manual for testing methods; usually it can be tested by using a multimeter.
Reset the Washing Machine: Sometimes, a simple reset can resolve the issue. Unplug the washing machine for 5-10 minutes, then plug it back in and try running a drain cycle.
Check for Error Codes: If your machine displays an error code, consult your owner’s manual to understand its meaning and recommended solutions.
Run a Calibration Cycle (if applicable): Some LG washing machines have a calibration cycle that can help resolve sensor issues. Refer to your owner’s manual for instructions.
Listen for the Motor: While the machine is trying to drain, carefully listen near the drain pump. Can you hear the motor humming or trying to run? This can indicate that the motor is receiving power but struggling to operate due to a blockage or internal issue.
Inspect the Drain Pipe: Ensure the drain pipe where the drain hose connects is not clogged. Use a plumber’s snake to clear any obstructions.

Fix the Issue Without Buying Parts

Before resorting to replacing parts, try these free methods:

Reset: As mentioned above, a simple reset can often resolve minor glitches.
Thorough Cleaning: Regularly clean the drain filter, drain hose, and drain pump housing.
Proper Detergent Use: Use the correct amount of detergent to avoid excessive suds.
Avoid Overloading: Do not overload the washing machine, as this puts extra strain on the drain motor.
Regular Maintenance: Periodically run an empty washing machine cycle with a cup of white vinegar to help prevent buildup and maintain cleanliness.
Check the Air Gap (if applicable): Some plumbing systems have an air gap near the drain connection. Make sure it is clear of debris.

When Replacement Might Be Necessary

If you’ve tried all the troubleshooting steps and the drain motor still isn’t working, it might be time to consider replacement. A new drain motor typically costs between $50 and $150 USD, depending on the model. Parts that commonly fail alongside the drain motor include the drain pump assembly and the water level sensor. However, before replacing any parts, consider if the washing machine is still under warranty.

Safety Warning

Always unplug the washing machine before performing any maintenance or repairs.
Be careful when handling water and electrical components. Avoid standing in water.
If you’re not comfortable working with electrical wiring, consult a qualified technician.
When testing the washing machine after performing any repairs, stay close to the appliance and monitor it closely to avoid flooding.
