Washer Won T Drain

Introduction

Finding a washer full of water after a cycle is never a welcome surprise. A washer that won’t drain can lead to standing water, potential water damage to your floors, and clothes that stay soaking wet. Acting quickly is important to prevent mold growth and further damage to your appliance and home. This guide will walk you through the common causes and troubleshooting steps to get your washer draining properly again.

Common Causes of Washer Won’t Drain

Several factors can prevent your washing machine from draining. Here are the most common culprits:

• Clogged Drain Hose: This is the most frequent cause. Lint, small objects, and soap residue can build up in the hose, blocking the water flow.
• Clogged Drain Pump Filter: Many washers have a filter to catch debris before it reaches the drain pump. A full filter restricts drainage.
• Drain Pump Malfunction: The drain pump is responsible for pushing water out of the washer. If it’s faulty, it won’t be able to do its job.
• Blocked Drainpipe: The standpipe that your drain hose connects to may be clogged.
• Lid Switch Problem: Some washers have a lid switch that prevents the machine from spinning and draining if the lid is open. A faulty switch can prevent draining.
• Belt Issues (for belt-driven models): A worn or broken belt connecting the motor to the pump can prevent the pump from working correctly.
• Control Panel/Timer Malfunction: Rarely, the control panel or timer may fail to send the signal to activate the drain pump.
• Kinked or Twisted Drain Hose: A simple kink can significantly restrict water flow.

Symptoms Checklist

Use this checklist to narrow down the possible causes:

• Washer fills with water but doesn’t empty after the wash cycle.
• You hear a humming or buzzing sound during the drain cycle, but no water is being pumped out.
• The washer stops mid-cycle and displays an error code related to draining.
• The drain hose feels unusually heavy or full.
• Water drains very slowly.
• You notice a foul odor coming from the washer.

How to Fix Washer Won’t Drain Step-by-Step Guide

Follow these steps to troubleshoot your washer:

1. Unplug the Washer: Safety first! Disconnect the washer from the power outlet before you begin.
2. Check the Drain Hose: Inspect the drain hose for kinks, twists, or pinches. Straighten any bends and ensure the hose isn’t crushed.
3. Detach the Drain Hose: Carefully detach the drain hose from both the washing machine and the standpipe (drainpipe in the wall).
4. Inspect the Drain Hose for Clogs: Hold the drain hose up and check for visible obstructions. Flush the hose with water from a garden hose or sink faucet to dislodge any blockages. You can also use a flexible wire or a plumbing snake to break up stubborn clogs.
5. Check the Standpipe: Make sure the standpipe isn’t clogged. Use a flashlight to inspect for any debris. A small brush or plumbing snake can clear any obstructions.
6. Locate and Clean the Drain Pump Filter: Most front-load washers have a drain pump filter located behind a small access panel near the bottom front of the machine. Top-load washers often have the filter inside the tub or near the pump. Consult your owner’s manual for the exact location.
7. Prepare for Water: Place a shallow pan or towels under the access panel before opening it, as some water will likely spill out.
8. Remove the Filter: Carefully unscrew or detach the drain pump filter.
9. Clean the Filter: Remove any lint, hair, coins, or other debris from the filter. Rinse it thoroughly with water.
10. Reinstall the Filter: Securely reattach the drain pump filter.
11. Reattach the Drain Hose: Reconnect the drain hose to the washing machine and the standpipe, ensuring it’s securely attached.
12. Check the Lid Switch (for Top-Load Washers): If your washer has a lid switch, try manually pressing it down to see if it allows the washer to drain. If the switch is faulty, it may need professional repair.
13. Plug in the Washer: Reconnect the washer to the power outlet.
14. Run a Drain/Spin Cycle: Select a drain/spin cycle to test if the washer is now draining properly.

Fix the Issue Without Buying Parts

Sometimes, a simple reset or maintenance can resolve the issue without needing to replace parts:

• Reset the Washer: Unplug the washer for 1-2 minutes, then plug it back in. This can sometimes reset the control panel and clear minor errors.
• Regular Cleaning: Run an empty washer cycle with a cup of white vinegar or a washing machine cleaner every month to prevent buildup of soap and mineral deposits.
• Avoid Overloading: Overloading the washer can strain the drain pump and prevent it from working efficiently.

When Replacement Might Be Necessary

If you’ve tried all the troubleshooting steps and the washer still won’t drain, the drain pump itself may be faulty. Replacing the drain pump typically costs between $80 and $250 (USD), including the part and labor if you hire a technician. The lid switch is another part that commonly fails and costs less to replace (around $50-$150). If your washer is old and the repair costs are significant, it might be more cost-effective to consider replacing the entire machine.

Safety Warning

• Always unplug the washer before performing any maintenance or repairs.
• Be careful when handling water near electrical outlets.
• Wipe up any spills immediately to prevent slips and falls.
• If you’re uncomfortable performing any of these steps, consult a qualified appliance repair technician.

Tools You May Need

• Screwdrivers (Phillips and flathead)
• Pliers
• Flashlight
• Shallow pan or towels
• Bucket
• Plumbing snake or flexible wire
• Garden hose
