How to Fix an LG Washer That Won’t Drain

Dealing with an LG washer that refuses to drain can be a frustrating interruption in your laundry routine. When a washer fails to drain, it often stops the entire cycle, leaving clothes soaked and the drum filled with water.

Understanding the underlying causes and applying targeted troubleshooting steps can help restore your washer’s performance efficiently.

Common Causes of LG Washer Not Draining

Drainage issues can stem from simple blockages or more complex mechanical failures.

A clogged pump filter or drain hose — often obstructed by lint, debris, or small objects — is one of the most common causes. In more serious cases, a malfunctioning drain pump may be responsible.

Identifying the root cause is the first step toward restoring your LG washer to full functionality.

Repair Instructions for the Most Frequent Issues

Check the Door Lock Switch

The door lock switch ensures the door is securely closed before the washer begins operating. If faulty, it may prevent the washer from draining.

1. Unplug the washer.
2. Locate the door lock switch on the top or side of the door frame.
3. Inspect for visible damage or loose connections.
4. Use a multimeter to test for continuity. If there is no continuity, replace the switch.

Rebalance the Load

An unbalanced load can prevent proper spinning and draining.

1. Pause the cycle and unplug the washer.
2. Open the door and redistribute items evenly.
3. Restart the cycle.
4. If the issue persists, proceed to further troubleshooting.

Drain the Washer Manually

Before continuing diagnostics, manually remove excess water.

1. Locate the drain hose at the back of the washer.
2. Place a bucket nearby.
3. Detach the hose and allow water to drain into the bucket.
4. Reconnect the hose securely.

Clean the Drain Pump Filter

A clogged filter can obstruct water flow.

1. Unplug the washer.
2. Locate the drain filter at the front or bottom panel.
3. Place a towel or bucket underneath.
4. Unscrew and remove the filter.
5. Rinse and remove debris.
6. Reinstall securely.

Inspect the Drain Hose

A kinked or blocked hose may prevent drainage.

1. Unplug the washer.
2. Inspect the hose for bends or obstructions.
3. Remove blockages using a brush or pipe cleaner.
4. Ensure the hose is properly positioned and reattached.

Check the Drain Pump

If previous steps fail, the drain pump may be defective.

1. Unplug the washer.
2. Access the drain pump via the rear or access panel.
3. Inspect for visible damage or debris.
4. Test for continuity with a multimeter. Replace if faulty.

Using the Wrong Detergent

Using regular detergent in a high-efficiency (HE) washer can produce excessive suds, interfering with drainage.

Always use HE detergent and follow manufacturer recommendations to prevent suds buildup and drainage issues.

If you are unsure about performing these inspections, professional assistance is recommended.

When to Call a Technician

If the drum still holds water after you have checked the door switch, filter, hose, and pump, the drain pump motor or the main control board is the likely cause, and that repair needs proper diagnostic tools.
