Drain Pump Washing Machine Blocked

Introduction

A blocked drain pump in your washing machine is a frustrating problem that prevents your clothes from being properly cleaned and can even lead to standing water in the drum. This usually happens when small objects like coins, lint, or even socks find their way into the drain system. Addressing a blocked drain pump promptly is important. Ignoring the problem can lead to more serious issues like pump failure or even water damage to your home. This guide will walk you through troubleshooting and fixing the problem yourself.

Common Causes of Drain Pump Washing Machine Blocked

Here are some of the most common culprits behind a blocked drain pump:

Small Objects: Coins, buttons, and other small items can slip through the wash and get lodged in the pump.
Lint Buildup: Over time, lint and fabric fibers accumulate and can clog the pump filter.
Hair: Hair strands can wrap around the pump impeller, hindering its ability to function.
Socks or Underwear: These smaller clothing items can sometimes squeeze past the drum and block the drain.
Soap Scum: Excessive use of detergent can lead to soap scum buildup in the drain pump area.
Sediment: Hard water can deposit minerals, leading to sediment buildup.
Broken Parts: Occasionally, small plastic pieces from worn or broken washing machine parts can cause a blockage.
Pet Hair: If you wash pet bedding or clothing, pet hair can easily clog the drain.

Symptoms Checklist

Here are some telltale signs that your washing machine drain pump might be blocked:

Washing machine is not draining properly.
Standing water remains in the drum after a wash cycle.
The washing machine makes a humming or buzzing sound during the drain cycle.
Error code related to draining appears on the washing machine display.

How to Fix Drain Pump Washing Machine Blocked Step-by-Step Guide

Follow these steps to troubleshoot and fix a blocked drain pump:

Unplug the Washing Machine: Safety first! Disconnect the washing machine from the power outlet.
Locate the Drain Pump Access Panel: This panel is usually at the bottom front or back of the machine. Consult your owner’s manual if you’re unsure.
Prepare for Water Spillage: Place a shallow pan or towels under the access panel to catch any water that may spill out.
Open the Access Panel: Use a screwdriver or your fingers to carefully open the access panel.
Locate the Drain Pump Filter: The filter is usually a round cap that you can unscrew.
Carefully Remove the Filter: Unscrew the filter slowly. Be prepared for water to come out.
Clean the Filter: Remove any lint, hair, coins, or other debris from the filter. Rinse it thoroughly with water.
Inspect the Drain Pump Housing: Look inside the drain pump housing for any obstructions. You might need a flashlight to see clearly. Use pliers or tweezers to remove any visible debris.
Check the Drain Hose: Disconnect the drain hose from the drain pump. Inspect it for kinks or blockages. Flush it out with water to remove any debris.
Reassemble the Filter: Reinstall the cleaned filter securely, making sure it’s tightly screwed in.
Close the Access Panel: Close and secure the access panel.
Reconnect the Drain Hose: If you disconnected it, reattach the drain hose to the drain pump.
Plug in the Washing Machine: Plug the washing machine back into the power outlet.
Run a Test Cycle: Run a short wash cycle to see if the washing machine drains properly.
Monitor for Leaks: Check for any leaks around the drain pump area during the test cycle.

Fix the Issue Without Buying Parts

Before resorting to replacement, try these methods:

Reset the Washing Machine: Unplug the washing machine for 5 minutes, then plug it back in and try running a cycle. This can sometimes clear error codes.
Vinegar Cleaning Cycle: Run an empty washing machine cycle with a cup of white vinegar to help dissolve soap scum and mineral deposits.
Inspect the Drain Hose: Ensure the drain hose isn’t kinked or bent, which can restrict water flow.
Check the Height of the Drain Hose: Make sure the drain hose is properly elevated to prevent siphoning. The correct height is usually specified in the washing machine’s manual.

When Replacement Might Be Necessary

If cleaning and troubleshooting don’t resolve the issue, the drain pump itself might be faulty. Signs of a failing pump include a loud grinding noise, complete failure to drain, or persistent error codes. A replacement drain pump typically costs between $50 and $200 USD, depending on the washing machine model. The impeller (the spinning part inside the pump) and the pump motor are common components that fail.

Safety Warning

Always unplug the washing machine before performing any maintenance or repairs.
Be careful when handling water near electrical components.
Avoid flooding the area by having towels or a pan ready for spills.
If you are uncomfortable performing these steps, consult a qualified appliance repair technician.
