How to Clean a Washing Machine Filter (Easy Step-by-Step Guide)

What Is a Washing Machine Filter?

The washing machine filter (also called the drain pump filter) traps:

• Lint and fabric fibers

• Coins and small objects

• Hair and debris

It protects the drain pump from damage and helps the washer drain properly.

When Should You Clean the Washing Machine Filter?

Clean the filter if you notice:

• Water draining slowly

• Bad smell from the washer

• Clothes not coming out clean

• Washer stopping mid cycle

• Unusual noise during draining

As routine maintenance, clean it every 1–3 months.

Things You Need

• Towel or old cloth

• Shallow tray or bowl

• Soft brush or old toothbrush

• Warm water

Always unplug the washing machine before starting.

Step 1: Locate the Washing Machine Filter

In most washers, the filter is located:

• Behind a small panel at the front bottom

• Near the drain pump

For top-load washers, the filter may be inside the drum or along the agitator.

Step 2: Prepare for Water Drainage

• Place a towel under the filter area

• Keep a tray ready to collect water

• Some water will spill out when you open the filter

This step prevents flooding.

Step 3: Open the Filter Carefully

• Slowly turn the filter knob counterclockwise

• Let the water drain gradually

• Once water stops flowing, fully remove the filter

Do not pull it out forcefully.

Step 4: Clean the Filter Thoroughly

• Remove lint, hair, coins, and debris

• Rinse the filter under warm running water

• Use a soft brush to remove stubborn dirt

Make sure all holes in the filter are clear.

Step 5: Clean the Filter Housing

• Look inside the filter cavity

• Remove any visible debris

• Wipe the area with a damp cloth

Check that the drain pump impeller spins freely.

Step 6: Reinstall the Filter Properly

• Insert the filter back into position

• Turn clockwise until it is snug

• Do not over-tighten

A loose filter can cause leaks.

Step 7: Test the Washing Machine

• Plug the washer back in

• Run a short rinse or spin cycle

• Check for leaks around the filter

If there is no leakage, the job is done.

Common Mistakes to Avoid

• Opening the filter without preparing for water

• Forgetting to unplug the washer

• Over-tightening the filter

• Ignoring debris inside the housing

• Never cleaning the filter at all

Extra Tips for Best Results

• Check pockets before washing clothes

• Clean the filter more often if you wash heavy fabrics

• Clean after washing pet bedding

• Keep the filter dry and clean

What Happens If You Don’t Clean the Filter?

A clogged filter can lead to:

• Drain pump failure

• Persistent bad odors

• Washer not draining

• Costly repairs

Regular cleaning prevents these problems.

Knowing how to clean a washing machine filter helps your washer drain better, smell fresher, and last longer. This simple maintenance task takes less than 15 minutes and can save you from expensive repairs.
