Laundry Washer Not Draining

Introduction

Is your washing machine full of water after the cycle is complete? A laundry washer not draining is a frustrating problem that can lead to wet laundry, a messy laundry room, and potential water damage. This usually happens because of a clog somewhere in the drainage system. Addressing this quickly is essential to prevent mold growth and further damage to your machine and home.

Common Causes of Laundry Washer Not Draining

Here are some of the most common reasons why your washer might not be draining:

Clogged Drain Hose: The drain hose is the flexible tube that carries water away from the washer. It can get blocked with lint, socks, or other small objects.
Clogged Drain Pump Filter: Many washers have a filter to catch debris before it reaches the drain pump. This filter can become clogged.
Drain Pump Malfunction: The drain pump is responsible for pushing water out of the washer. If it’s broken, it won’t drain properly.
Kinked or Blocked Drain Hose: A kink in the drain hose restricts water flow. Check for bends or twists.
Clogged Drain Pipe: The pipe in your wall that the drain hose connects to could be clogged.
Lid Switch Problem: Some washers won’t drain if the lid switch (which detects if the lid is closed) is faulty.
Air Lock in Drain Hose: Sometimes an air bubble can prevent the water from draining.
Too Much Detergent: Using too much detergent can lead to excessive suds that interfere with the draining process.

Symptoms Checklist

Here’s how to tell if your laundry washer is not draining properly:

Water remains in the drum after the wash cycle.
The washer makes unusual noises during the drain cycle.
You notice wet laundry after a completed cycle.
The drain hose is visibly kinked or blocked.
Error codes related to drainage appear on the washer’s display.

How to Fix Laundry Washer Not Draining Step-by-Step Guide

Follow these steps to troubleshoot a laundry washer that won’t drain:

Unplug the Washer: For your safety, disconnect the washer from the power outlet before starting any repairs.
Locate the Drain Hose: It’s usually a flexible hose connected to the back of the washer.
Inspect the Drain Hose for Kinks: Straighten out any kinks or bends in the hose.
Detach the Drain Hose: Carefully disconnect the hose from the drainpipe in the wall or standpipe.
Check for Clogs in the Drain Hose: Hold the hose up and look through it to see if anything is blocking it. You can use a straightened wire hanger or a plumbing snake to dislodge any debris. Flush it with water to clear any remaining blockage.
Check the Drainpipe: If the drain hose is clear, the problem might be in the drainpipe in the wall. Shine a flashlight down the drainpipe to look for clogs. If you see something, try to remove it with a plumbing snake or pliers.
Locate the Drain Pump Filter: This is usually located on the front of the washer, near the bottom. Some washers have a small access panel you need to open. Check your owner’s manual if you can’t find it.
Drain Remaining Water (Carefully!): Place a shallow pan or towels beneath the drain pump filter access panel to catch any water that spills out when you remove the filter.
Remove and Clean the Drain Pump Filter: Unscrew the filter cap (it might be tight) and pull out the filter. Clean any lint, hair, or debris from the filter.
Reinstall the Drain Pump Filter: Replace the filter and screw the cap back on tightly.
Check the Drain Pump (If Accessible): In some models, you can visually inspect the drain pump impeller (the little fan inside) to see if it’s blocked by anything.
Try a Rinse and Spin Cycle: After checking everything, plug the washer back in and run a rinse and spin cycle to see if it drains properly.
Check the Lid Switch: Make sure the lid switch is engaging correctly. Sometimes, it can be faulty. (Refer to your washer’s manual for testing).
Reduce Detergent Usage: Try using less detergent in future loads to prevent excessive suds.

Fix the Issue Without Buying Parts

Before you think about replacing parts, try these free methods:

Washer Reset: Try unplugging the washer for 5-10 minutes, then plugging it back in. This can sometimes reset the computer and resolve minor issues.
Recalibration: Refer to your washer’s manual to see if there’s a recalibration procedure. This can help the washer relearn its settings.
Regular Cleaning: Clean your washer regularly to prevent buildup of detergent and debris.
Inspect Hoses Regularly: Check the drain hose and inlet hoses for any signs of damage or wear.

When Replacement Might Be Necessary

If you’ve tried all the troubleshooting steps and your washer still won’t drain, the drain pump itself might be faulty and need replacement. Drain pump replacement can range from $80-$200, depending on the washer model. The lid switch is also another possible replacement, cost is around $30-$75.

Safety Warning

Always unplug the washer before attempting any repairs.
Be careful when dealing with water; mop up any spills immediately to prevent slips.
If you’re not comfortable with electrical or plumbing repairs, it’s best to call a qualified technician.
