Unraveling the mystery: why is my lg washer not draining?

A malfunctioning washing machine can be a major inconvenience, especially when it refuses to drain. If you’re facing this issue with your LG washer, you’re not alone. Understanding the underlying causes can help you troubleshoot and resolve the problem efficiently. In this comprehensive guide, we’ll delve into the reasons why your LG washer may not be draining and provide step-by-step solutions to get your laundry flowing again.

Common Causes and Solutions

1. Clogged Drain Hose

Cause: A kinked, clogged, or frozen drain hose can obstruct water flow.

Solution: Inspect the drain hose for any visible kinks or obstructions. If it’s frozen, thaw it using warm water or a hair dryer. If the hose is clogged, disconnect it from the washer and use a drain snake or a wet/dry vacuum to clear the blockage.

2. Faulty Drain Pump

Cause: A malfunctioning drain pump is unable to expel water from the tub.

Solution: Test the drain pump by running a diagnostic cycle or manually activating it using the control panel. If the pump doesn‘t operate, it may need to be replaced.

3. Blocked Drain Filter

Cause: Debris and lint can accumulate in the drain filter, preventing water from draining.

Solution: Locate the drain filter, usually at the bottom of the washer, and remove it. Clean the filter thoroughly under running water and reinstall it securely.

4. Defective Door Lock

Cause: A faulty door lock can prevent the washer from draining if it doesn’t engage properly.

Solution: Check if the door is securely closed and latched. If the lock still doesn’t engage, it may need to be adjusted or replaced.

5. Malfunctioning Pressure Switch

Cause: The pressure switch monitors the water level in the tub. If it fails, the washer may not drain properly.

Solution: Test the pressure switch using a multimeter. If it’s defective, it needs to be replaced.

6. Faulty Control Board

Cause: The control board is the brain of the washer and controls various functions, including draining.

Solution: Reset the control board by unplugging the washer for 30 minutes. If the problem persists, the control board may need to be repaired or replaced.

7. Water Inlet Valve Issues

Cause: A malfunctioning water inlet valve can prevent water from entering the tub, which can affect the draining process.

Solution: Check if the water inlet valve is clogged or damaged. If necessary, clean or replace the valve to ensure proper water flow.

Troubleshooting Tips

• Check for error codes: LG washers display error codes on the control panel to indicate specific issues. Refer to the user manual to decode the error and identify the appropriate solution.
• Use a drain pump cleaner: If the drain pump is clogged, a drain pump cleaner can help dissolve buildup and improve water flow.
• Inspect the belt: A worn or broken belt can prevent the drain pump from operating. Check the belt for any signs of damage or wear and replace it if necessary.

Prevention Tips

• Clean the drain filter regularly to prevent debris accumulation.
• Avoid overloading the washer, as it can strain the drain pump.
• Use a mesh laundry bag to catch lint and small items that could clog the drain.
• Run a hot water cycle occasionally to flush out any buildup in the drain hose and pump.

When to Call a Professional

If you’ve tried the troubleshooting steps above and your LG washer is still not draining, it’s recommended to contact a qualified appliance repair technician. They can diagnose the problem accurately and perform the necessary repairs to restore your washer’s functionality.
