Washing Machine Drain Pump Not Working

Introduction

A washing machine that won’t drain can be a major headache. Nobody wants a tub full of soapy water and wet clothes! This problem is often due to a malfunctioning drain pump, the component responsible for pushing water out of your machine after the wash cycle. It’s important to address this issue quickly to prevent mold growth, foul odors, and potential damage to your washing machine and home. Let’s explore how to troubleshoot the washing machine drain pump not working.

Common Causes of washing machine drain pump not working

Here are some common reasons why your washing machine’s drain pump might not be working:

Clogged Drain Hose: A kinked or blocked drain hose restricts water flow.
Clogged Drain Pump Filter: This filter traps debris like lint, hair, and small objects, and can become clogged over time.
Foreign Objects in the Pump: Socks, coins, or other small items can get lodged in the pump, preventing it from spinning.
Faulty Drain Pump Motor: The motor itself might be burned out or damaged.
Blocked Drainpipe: The drainpipe that your washing machine connects to could be clogged.
Wiring Problems: Loose or damaged wires connecting to the drain pump can interrupt its power supply.
Control Board Issues: In rare cases, a faulty control board might not be sending the correct signals to the drain pump.
Air Lock: Air trapped in the drain hose can prevent water from flowing freely.

Symptoms Checklist

Here are some indicators that your washing machine drain pump might be the problem:

The washing machine tub is full of water after the wash cycle.
You hear a humming or buzzing sound from the pump area, but no water is draining.
The washing machine displays an error code related to draining.
The drain cycle takes an unusually long time.
You notice leaking around the drain pump area.

How to Fix washing machine drain pump not working Step-by-Step Guide

Follow these steps to troubleshoot your washing machine’s drain pump:

Safety First: Unplug the washing machine from the power outlet before you begin. This is crucial to avoid electrical shock.
Locate the Drain Pump: The drain pump is usually located at the bottom of the washing machine, either at the front or the back. Consult your owner’s manual for the exact location.
Access the Drain Pump Filter: Many washing machines have a small access panel for the drain pump filter. Open the panel.
Prepare for Water: Place a shallow pan or towels under the access panel to catch any water that might spill out when you remove the filter.
Remove the Drain Pump Filter: Carefully unscrew or pull out the drain pump filter. Be prepared for some water to come out.
Clean the Filter: Thoroughly clean the filter under running water, removing any lint, hair, or debris.
Inspect the Pump Housing: Shine a flashlight into the pump housing and check for any obstructions like coins, buttons, or small objects. Use pliers or tweezers to remove anything you find.
Check the Drain Hose: Disconnect the drain hose from the back of the washing machine and inspect it for kinks or clogs. Straighten any kinks and flush out any blockages with water.
Reassemble: Reinstall the drain pump filter and secure the access panel. Reconnect the drain hose.
Check the Drain Pipe: Ensure the drain pipe where the washing machine connects to is clear and free of obstruction.
Test the Washing Machine: Plug the washing machine back in and run a short drain/spin cycle to see if the problem is resolved.
Listen for Pump Noise: During the drain cycle, listen closely to the drain pump. If you hear a humming sound but no water is draining, it could indicate a problem with the pump motor.

Fix the Issue Without Buying Parts

Before considering replacing any parts, try these free methods:

Reset the Washing Machine: Unplug the washing machine for 5-10 minutes, then plug it back in. This can sometimes reset the control board and resolve minor issues.
Check for Air Locks: Ensure the drain hose is not inserted too far into the drainpipe, as this can create an air lock. Leave some air gap.
Regular Cleaning: Regularly clean the drain pump filter (every 1-3 months, depending on usage) to prevent clogs.
Avoid Overloading: Overloading the washing machine can strain the drain pump. Avoid stuffing too many clothes into each load.
Use the Right Amount of Detergent: Using too much detergent can create excessive suds, which can clog the drain pump.

When Replacement Might Be Necessary

If you’ve tried all the troubleshooting steps and the drain pump still isn’t working, it might need to be replaced. This is usually necessary if the pump motor is burned out or damaged. A new drain pump typically costs between $50 and $200, depending on the washing machine model. Commonly failing parts besides the pump motor are the impeller (the part that spins to move water) and the pump housing itself if it becomes cracked.

Safety Warning

Please adhere to these safety guidelines:

Always unplug the washing machine from the power outlet before performing any repairs or inspections.
Be careful when working with water and electrical components to avoid electrical shock.
Clean up any spills immediately to prevent slips and falls.
If you are uncomfortable performing any of these steps, consult a qualified appliance repair technician.
