LG Washer Not Draining Water: Causes and Fixes by Fast Appliance Repair in Calgary


Washing machines are essential for households. When your LG washer doesn’t drain, it can be frustrating. At Fast Appliance Repair, we understand how crucial it is to have a functional washer. In this guide, I’ll explore common causes and provide solutions.

Common Causes of LG Washer Not Draining

1. Clogged Drain Pump Filter

The drain pump filter can get clogged with debris. This can block water from draining. Regularly clean the filter to avoid this issue.

2. Kinked or Clogged Drain Hose

The drain hose can become kinked or clogged. A kinked hose restricts water flow, while a clog stops it completely. Check the hose for kinks or clogs and fix them promptly.

3. Faulty Drain Pump

The drain pump is responsible for expelling water from the washer. If it’s faulty, water won’t drain. You might hear strange noises from the pump if it’s broken. Replacing the pump is usually the best solution.

4. Blocked Drain Outlet

The drain outlet where the hose connects to your home’s plumbing can become blocked. This blockage prevents water from leaving the washer. Clearing the blockage will resolve the issue.

5. Malfunctioning Lid Switch Assembly

The lid switch assembly ensures the washer lid is closed during operation. If it’s malfunctioning, the washer might not drain. Replacing the lid switch assembly can fix this problem.

6. Issues with the Control Board

The control board manages the washer’s functions. If it’s defective, the washer might not drain. You may need a professional to diagnose and fix control board issues.

7. Poor Installation

Improper installation can cause draining problems. Ensure the washer is level and the drain hose is installed correctly. A professional installation can prevent many issues.

Fixing Your LG Washer’s Drainage Problem

1. Clean the Drain Pump Filter

Locate the drain pump filter. It’s usually behind a small door at the front of the washer. Place a towel under the filter to catch any water. Turn the filter counterclockwise to remove it. Clean out any debris and rinse the filter under running water. Reinstall the filter and test the washer.

2. Check and Straighten the Drain Hose

Unplug the washer and pull it away from the wall. Inspect the drain hose for kinks. Straighten any kinks and ensure the hose is not twisted. If the hose is clogged, detach it from the washer and the drain outlet. Use a long, flexible brush to clear any obstructions. Reattach the hose and test the washer.

3. Replace the Drain Pump

If the drain pump is faulty, you’ll need to replace it. Unplug the washer and remove the back panel. Locate the drain pump and disconnect the wires and hoses attached to it. Remove the mounting screws and take out the old pump. Install the new pump by reversing these steps. Reassemble the washer and test it.

4. Clear the Drain Outlet

Detach the drain hose from the outlet and inspect the outlet for blockages. Use a plumber’s snake to clear any obstructions. Reattach the hose and ensure it’s securely connected. Test the washer to ensure water drains properly.

5. Replace the Lid Switch Assembly

If the lid switch assembly is faulty, replace it. Unplug the washer and remove the top panel. Locate the lid switch assembly and disconnect the wires. Remove any mounting screws and take out the old switch. Install the new switch by reversing these steps. Reassemble the washer and test it.

6. Diagnose and Repair the Control Board

Diagnosing control board issues can be complex. If you suspect the control board is faulty, call Fast Appliance Repair. Our technicians can diagnose the problem and replace the control board if needed.

7. Ensure Proper Installation

Check that your washer is level. Adjust the feet if necessary. Ensure the drain hose is properly installed and not inserted too far into the drain pipe. If you’re unsure about the installation, contact Fast Appliance Repair for professional assistance.

Preventative Maintenance Tips

1. Regularly Clean the Drain Pump Filter

Check and clean the drain pump filter every few months. This prevents debris from building up and causing blockages.

2. Inspect the Drain Hose

Periodically check the drain hose for kinks and clogs. Straighten any kinks and clear any clogs to maintain proper drainage.

3. Use the Right Detergent

Use high-efficiency (HE) detergent in your LG washer. Using the wrong detergent can cause excess suds, which can lead to drainage issues.

4. Avoid Overloading the Washer

Overloading the washer can strain the drain pump and other components. Follow the manufacturer’s guidelines for load sizes to ensure efficient operation.

Schedule regular maintenance with Fast Appliance Repair. Our technicians can inspect your washer, clean components, and address any potential issues before they become major problems.
