Common Causes of lg washing machine won t drain water
Several factors can prevent your LG washing machine from draining. Here are some of the most common:
- Clogged Drain Hose: The drain hose carries water away from the machine. If it’s kinked, bent, or blocked by lint or debris, the water can’t escape.
- Clogged Drain Pump Filter: The drain pump filter is designed to catch lint, buttons, and other small objects that could damage the pump. A full filter restricts water flow.
- Drain Pump Malfunction: The drain pump actively pushes the water out of the machine. If the pump is broken or has a foreign object stuck inside, it won’t work properly.
- Blocked Drain Pipe: The pipe where the drain hose connects to your plumbing might be clogged.
- Air Lock in Drain Hose: Sometimes, air can get trapped in the drain hose, creating a blockage.
- Lid Switch Problem: In some models, if the lid switch isn’t functioning correctly (telling the machine the lid is closed), the drain cycle won’t start.
- Faulty Water Level Sensor: The water level sensor tells the machine how much water is inside. If it malfunctions, the machine might not realize it needs to drain.
- Control Panel Issues: While less common, a problem with the control panel or its settings can sometimes prevent the drain cycle from initiating.
Symptoms Checklist
Here’s a quick checklist to help you pinpoint the problem:
- Water remains in the drum after the wash cycle completes.
- You hear a humming noise but no draining.
- The machine displays an error code related to draining (check your user manual for codes).
- The drain hose is kinked or bent.
- The drain pump area is visibly blocked with lint or debris.

How to Fix lg washing machine won t drain water Step-by-Step Guide
Follow these steps to troubleshoot your LG washing machine:
- Unplug the Washing Machine: Safety first! Disconnect the washing machine from the power outlet before you begin.
- Locate the Drain Hose: This is usually a corrugated hose at the back of the machine.
- Inspect the Drain Hose: Look for kinks, bends, or blockages. Straighten any kinks and make sure the hose isn’t crushed.
- Detach the Drain Hose: Carefully detach the drain hose from the drainpipe or standpipe where it’s connected. Have a bucket ready to catch any water that might spill.
- Check for Blockages in the Drain Hose: Shine a flashlight through the hose to see if you can spot any obstructions. You can also try flushing the hose with water from a garden hose to dislodge debris.
- Locate the Drain Pump Filter: This is usually located at the bottom front of the washing machine, behind a small access panel. Consult your owners manual for the exact location.
- Prepare for Water Spill: Place a shallow pan or towels beneath the access panel to catch any water that will spill out.
- Open the Drain Pump Filter Access Panel: Usually, you can open it with a flathead screwdriver or your fingers.
- Remove the Drain Pump Filter: Slowly unscrew the drain pump filter. Be prepared for water to gush out.
- Clean the Drain Pump Filter: Rinse the filter under running water to remove any lint, hair, coins, or other debris.
- Inspect the Drain Pump Cavity: After removing the filter, shine a flashlight into the drain pump cavity. Check for any obstructions. You can try reaching in with your fingers (unplugged!) to feel for anything stuck.
- Reinstall the Drain Pump Filter: Securely screw the drain pump filter back into place. Make sure it’s tight, but don’t overtighten it.
- Reattach the Drain Hose: Reconnect the drain hose to the drainpipe or standpipe. Ensure it’s securely attached.
- Plug in the Washing Machine: Reconnect the washing machine to the power outlet.
- Run a Test Cycle: Run a short drain and spin cycle to see if the problem is resolved. Observe if the water drains correctly.
Fix the Issue Without Buying Parts
Before you consider replacing any parts, try these free troubleshooting methods:
- Reset the Washing Machine: Unplug the machine for 5-10 minutes, then plug it back in. This can sometimes reset the control panel and clear minor errors.
- Check for Error Codes: Consult your user manual for a list of error codes and their corresponding solutions.
- Maintenance Wash: Run a cleaning cycle with a washing machine cleaner to remove build-up inside the drum and hoses.
- Avoid Overloading: Overloading the washing machine can put extra strain on the drain pump. Follow the manufacturer’s guidelines for load size.
When Replacement Might Be Necessary
If you’ve tried all the troubleshooting steps and your washing machine still won’t drain, the drain pump itself might be faulty and need replacement. A new drain pump typically costs between $50 and $150 USD, depending on the model. Other less common, but potentially costly replacements include the water level sensor ($30 – $80) or the control panel ($100 – $300). However, always diagnose the issue thoroughly before replacing any parts. If you’re not comfortable replacing parts yourself, it’s best to call a qualified appliance repair technician.
