Washing Machine Intermittently Not Draining

Introduction

A washing machine that intermittently doesn’t drain is a common, and frankly, annoying problem. Imagine your clothes are clean, but they’re sitting in a pool of dirty water! This issue can occur sporadically sometimes the machine drains perfectly fine, and other times it leaves you with a soggy mess. Addressing this promptly is crucial to prevent mold growth, foul odors, and potential damage to your clothing and washing machine. This guide walks you through the steps to diagnose and fix the problem without necessarily resorting to expensive repairs.

Common Causes of Washing Machine Intermittently Not Draining

Here are some common reasons why your washing machine might be occasionally refusing to drain:

Clogged Drain Hose: The hose that carries water from the machine to the drain can become blocked with lint, hair, or small objects.
Clogged Drain Pump Filter: Many washing machines have a filter near the drain pump to catch debris. This can get clogged over time.
Kinked or Blocked Drain Hose: A kink in the hose can restrict water flow, or something might be lodged inside.
Faulty Drain Pump: The drain pump is responsible for pushing water out of the machine. If it’s failing, it might work intermittently.
Blocked Drainpipe: The drainpipe in your wall where the washing machine hose connects could be clogged.
Air Lock in Drain Hose: Air trapped in the drain hose can prevent proper drainage.
Control Panel or Timer Issues: In some cases, problems with the washing machine’s control panel or timer can cause drainage issues.
Overuse of Detergent: Excess detergent can lead to suds buildup, hindering drainage.

Symptoms Checklist

Use this checklist to confirm that you are experiencing intermittent drainage problems:

Water remains in the washing machine drum after the wash cycle completes.
The washing machine drains sometimes but not other times.
You hear a humming or buzzing sound from the drain pump, but no water is draining.
You may notice a musty odor emanating from the washing machine.
Clothes are excessively wet after the spin cycle.
Error codes related to drainage issues are displayed on the machine’s control panel (if applicable).

How to Fix Washing Machine Intermittently Not Draining Step-by-Step Guide

Unplug the Washing Machine: For safety, always disconnect the washing machine from the power outlet before attempting any repairs.
Locate the Drain Hose: This hose is usually located at the back of the washing machine.
Inspect the Drain Hose for Kinks: Ensure the hose isn’t bent or pinched, as this can restrict water flow. Straighten any kinks you find.
Detach the Drain Hose: Carefully disconnect the hose from both the washing machine and the drainpipe in the wall. Have a bucket ready to catch any remaining water.
Flush the Drain Hose: Run water through the hose to dislodge any blockages. You can use a garden hose for this.
Check the Drainpipe: While the drain hose is detached, check the drainpipe in the wall for clogs. You can use a drain snake or a wire hanger to clear any obstructions.
Locate the Drain Pump Filter: Consult your washing machine’s manual to find the location of the drain pump filter. It’s usually located at the bottom front of the machine, behind a small access panel.
Clean the Drain Pump Filter: Carefully remove the filter and clean it thoroughly. Remove any lint, hair, coins, or other debris.
Inspect the Drain Pump: With the filter removed, visually inspect the drain pump for any visible obstructions. If you see something, try to carefully remove it with pliers or tweezers.
Reassemble and Test: Reattach the drain hose to the washing machine and the drainpipe. Reinstall the drain pump filter. Plug the washing machine back in.
Run a Test Cycle: Select a short wash cycle and observe if the washing machine drains properly.
Check for Air Locks: If the machine still doesn’t drain, try gently tilting the washing machine forward or backward to release any trapped air in the drain hose.
Reduce Detergent Use: Try using less detergent in future washes to prevent excessive suds buildup.
Run a Cleaning Cycle: Some washing machines have a self-cleaning cycle that helps remove buildup and debris. Run this cycle according to the manufacturer’s instructions.

Fix the Issue Without Buying Parts

Before considering replacing any parts, try these free methods:

Reset the Washing Machine: Unplug the machine for a few minutes, then plug it back in. This can sometimes reset the control panel and resolve minor issues.
Regular Cleaning: Clean the washing machine regularly with a washing machine cleaner to prevent buildup of detergent, lint, and mildew.
Maintenance: Leave the washing machine door slightly ajar after each wash to allow air circulation and prevent mold growth.
Inspection Tips: Visually inspect the drain hose and pump filter regularly for any signs of clogs or damage.

When Replacement Might Be Necessary

If you’ve tried all the troubleshooting steps and the washing machine still intermittently fails to drain, the drain pump may need replacement. A new drain pump typically costs between $50 and $150 USD, depending on the model of your washing machine. Control boards can also cause intermittent issues, and these range from $100-$300. Before replacing, it’s recommended to consult a qualified appliance repair technician. They can properly diagnose the problem.

Safety Warning
