Washing Machine Not Draining Completely

Introduction

A washing machine that won’t drain completely is a frustrating and potentially messy problem. It means wet clothes stay sitting in the drum, risking mildew and unpleasant odors. This issue can happen after any load, but you’re most likely to notice it after washing bulky items like blankets or towels. Addressing a draining problem quickly is important to prevent damage to your machine and avoid a flooded laundry room.

Common Causes of washing machine not draining completely

Several factors can cause your washing machine to retain water:

Clogged Drain Hose: The hose that carries water away from the machine can get blocked with lint, debris, or small objects.
Blocked Drain Pump Filter: Most washing machines have a filter to catch lint and small items before they reach the drain pump. This can become clogged.
Kinked or Damaged Drain Hose: A kink in the hose restricts water flow, while damage can cause leaks and prevent proper draining.
Faulty Drain Pump: The drain pump is responsible for pushing water out of the machine. If it’s malfunctioning, it may not be able to pump efficiently.
Blocked Drainpipe: The pipe in your wall where the drain hose connects can be clogged.
Air Lock: An air bubble trapped in the drain hose can prevent water from flowing freely.
Overloading the Machine: Too many clothes can restrict water flow and prevent complete drainage.
Lid Switch Problems: In some older models, a faulty lid switch can prevent the drain cycle from starting.
Control Panel Issues: A malfunctioning control panel might not properly initiate the drain cycle.

Symptoms Checklist

Use this checklist to confirm the issue:

Water remains in the drum after the wash cycle.
The machine makes a humming or buzzing noise during the drain cycle, but no water drains.
The drain cycle takes longer than usual.
Error codes related to draining appear on the machine’s display.
Water drains very slowly.
You can smell a musty odor from the washing machine.

How to Fix washing machine not draining completely Step-by-Step Guide

Unplug the Washing Machine: For safety, always disconnect the power before attempting any repairs.
Locate the Drain Hose: It’s usually at the back of the machine.
Check 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 (or standpipe). Have a bucket ready to catch any water.
Inspect and Clean the Drain Hose: Check for clogs. You can use a garden hose or a long, flexible brush to clear any obstructions.
Locate the Drain Pump Filter: Consult your owner’s manual for its exact location. It’s often at the front, near the bottom of the machine, behind a small access panel.
Drain the Remaining Water: Place a shallow pan or towels to catch the water that will spill out when you open the filter.
Clean the Drain Pump Filter: Remove the filter and clean it thoroughly. Remove any lint, hair, coins, or other debris.
Inspect the Drain Pump Area: With the filter removed, check the area where the pump sits for any obstructions. You might need a flashlight.
Reassemble the Filter and Hose: Securely reattach the drain pump filter and the drain hose.
Check the Drainpipe (Standpipe): If the issue persists, the drainpipe in the wall might be clogged. You can use a plumbing snake to clear it.
Run a Test Cycle: Plug the machine back in and run a short wash cycle to see if it drains properly.
Listen for Unusual Noises: If you hear a loud humming or buzzing sound during the drain cycle, the drain pump might be failing.
Check the Air Vent (if applicable): Some washing machines have an air vent to prevent siphoning. Make sure it’s not blocked.

Fix the Issue Without Buying Parts

Before considering replacements, try these free methods:

Reset the Washing Machine: Unplug the machine for 1-2 minutes, then plug it back in. This can sometimes reset the control panel and resolve minor issues.
Clean the Machine Regularly: Run an empty wash cycle with a washing machine cleaner or a cup of white vinegar every month to prevent buildup.
Inspect the Rubber Bellows/Gasket: If you have a front-load washer, check the rubber seal around the door for trapped debris.
Proper Loading: Avoid overloading the machine. Follow the manufacturer’s guidelines for load size.

When Replacement Might Be Necessary

If the problem persists after trying all the troubleshooting steps, a part might need replacing. The most common part to fail is the drain pump. A new drain pump typically costs between $50 and $150 USD. Consider professional help if you’re not comfortable replacing parts yourself.

Safety Warning

Always unplug the washing machine before attempting any repairs.
Be careful when handling water to avoid slips and falls.
Do not attempt to repair the machine if you’re not comfortable working with electricity.
Protect your eyes when cleaning the drain pump area.
Turn off the water supply valve if you suspect a leak.
