Why Your LG Washer Isn’t Draining: Solutions & Maintenance Tips

Ever wondered why your LG washer isn’t draining properly? Picture this: you’ve just finished a load of laundry, eagerly anticipating fresh, clean clothes, only to find a pool of water at the bottom of the washer. Frustrating, right? Don’t worry, you’re not alone in facing this pesky issue.

In this article, you’ll uncover the reasons behind your LG washer’s draining woes and learn simple yet effective solutions to get it back up and running smoothly. No more standing water or soggy laundry to deal with – just the satisfaction of a job well done. Let’s dive in and troubleshoot together.

Common Reasons for LG Washer Not Draining

If you find yourself dealing with a LG washer not draining, several factors could be causing this frustrating issue. Here are some common reasons why this might be happening:

  • Clogged Drain Hose: Dirt, lint, or foreign objects may be obstructing the drain hose, impeding water flow.
  • Faulty Drain Pump: A malfunctioning drain pump can prevent water from being properly expelled during the wash cycle.
  • Clogged Drain Filter: A clogged drain filter restricts water flow, leading to poor draining performance.
  • Imbalanced Load: Overloading your washer or having an uneven distribution of clothes can affect the draining process.
  • Issues with the Lid Switch: If the lid switch is faulty, it can disrupt the washer’s drainage cycle.

Addressing these common causes can help you troubleshoot the issue and get your LG washer back to draining properly.

Check the Drain Hose

When your LG washer isn’t draining properly, the drain hose could be the culprit. Follow these steps to ensure it’s functioning correctly:

  • Inspect the hose: Check for bends, kinks, or clogs.
  • Positioning: Make sure the hose isn’t inserted too far into the drain standpipe.
  • Height: The height of the drain should be between 39-96 inches from the bottom of the washer.

Remember: A properly installed and maintained drain hose is crucial for efficient drainage in your LG washer.

Inspect the Drain Pump

When your LG washer is not draining, one crucial component to check is the drain pump. This pump is responsible for removing water from the machine during the draining process. If the drain pump malfunctions or gets clogged, it can lead to draining issues. Here’s how to inspect it:

  • Locate the Drain Pump: You can typically find the drain pump behind an access panel at the front or back of the washer. Refer to your user manual for specific instructions on accessing the pump.
  • Check for Debris: Inspect the drain pump for any obstructions like lint, socks, or other foreign objects that may be blocking the pump’s operation.
  • Test the Pump: Manually rotate the pump’s impeller to ensure it moves freely. If you encounter any resistance or strange noises, it may indicate a problem with the pump.
  • Inspect the Pump Housing: Look for cracks or damage to the pump housing that may be affecting its ability to function properly.
  • Verify Electrical Connections: Make sure the pump is properly connected to the washer’s electrical system. Loose connections can prevent the pump from operating efficiently.
  • Consider Professional Help: If you’re unsure about diagnosing or repairing the drain pump yourself, it’s best to seek assistance from a qualified technician to avoid causing further damage.

Ensure the drain pump is in good condition to help resolve drainage issues efficiently.

Clean the Filter

To ensure your LG washer drains properly, cleaning the filter is crucial. A clogged filter can impede water flow, leading to drainage issues. Here are the steps to follow:

  • Locate the filter: Typically found at the front bottom of the washer.
  • Remove the filter: Twist or pull it out, depending on the model.
  • Inspect for debris: Check for lint, loose coins, or any obstructions.
  • Clean the Filter: Use a brush or cloth to remove built-up debris.
  • Reinsert the filter: Ensure it is securely back in place before running the washer.

Regular filter maintenance is essential for efficient draining.

Run Diagnostics and Seek Professional Help If Needed

If you’ve tried cleaning the filter and checking for any obstructions, but your LG washer is still not draining properly, it may be time to run some diagnostics and consider seeking professional assistance. Here’s what you can do:

  • Run a diagnostic cycle to pinpoint any specific error codes that could indicate what’s causing the drainage issue. Refer to your owner’s manual for instructions on how to initiate this cycle.
  • Inspect the drain hose for any kinks, twists, or clogs that might be impeding the flow of water out of the washer. Ensure the hose is properly connected and free of any blockages.
  • Test the drain pump to see if it’s functioning correctly. Listen for any unusual noises during the draining process, which could signal a problem with the pump.
  • If after performing these checks you’re still unable to resolve the drainage issue, it may be time to contact a professional technician. They’ll have the expertise and tools to diagnose the problem accurately and recommend the best course of action to get your LG washer draining properly again.

Remember, taking proactive steps to address drainage issues early on can prevent more significant problems down the line. So, don’t hesitate to seek help if you’re struggling to get your washer back in working order.


Ensuring your LG washer’s drain pump is well-maintained is crucial for proper drainage.
