One Plastic Bottle Is All You Need to Clean Your Washing Machine Filter

The washing machine is one of the hardest-working appliances in the home, yet many people forget that it requires regular maintenance.

One of the most important parts to clean is the drain-pump filter. Its job is to catch lint, coins, hair, buttons, tissues, and other small objects before they enter the drainage system.

When the filter becomes clogged, the machine may drain slowly, leave clothes soaking wet, develop unpleasant odors, or display an error code. In severe cases, a neglected filter can contribute to leaks or expensive repairs.

Fortunately, an empty plastic bottle can make the cleaning process much easier and help prevent dirty water from spilling across the floor.

Why You Should Clean the Washing Machine Filter

During every wash cycle, small particles can travel through the drum and collect inside the filter.

Over time, this buildup may lead to:

Slow or incomplete drainage
Bad smells inside the machine
Excess water remaining in the drum
Unusual noises during draining
Longer wash cycles
Reduced washing performance

Checking the filter regularly can help your washing machine operate more efficiently and may prevent avoidable service calls.

What You Will Need

Prepare the following items:

An empty plastic bottle
Scissors or a utility knife
An old towel
A shallow tray or container
A small cleaning brush or old toothbrush
Warm water
Protective gloves

Step 1: Switch Off the Washing Machine

Before opening the filter compartment, turn off the machine and unplug it from the electrical outlet.

If the appliance has just completed a hot cycle, allow the water inside to cool before continuing.

Step 2: Locate the Filter

The drain-pump filter is commonly found behind a small access panel near the bottom front of the washing machine.

The exact location may vary between models, so consult the appliance manual when necessary.

Place a thick towel on the floor beneath the access panel. Even after a cycle has finished, some water may remain inside the machine.

Step 3: Turn a Bottle into a Water Catcher

Take an empty plastic bottle and cut off the upper section.

Next, remove part of one side so that the bottle can fit beneath the filter opening. The cut bottle should form a small channel that directs water into a bowl or tray instead of allowing it to spread across the floor.

Smooth any sharp plastic edges before using it.

Step 4: Drain the Remaining Water

Position the cut bottle directly beneath the filter.

Some washing machines have a small emergency drain hose beside the filter. When present, remove its cap and slowly drain the water into a container.

Otherwise, carefully turn the filter counterclockwise a small amount. Do not remove it completely at once.

Allow the trapped water to flow through the bottle and into the tray. Tighten the filter temporarily whenever the container needs to be emptied.

Continue until no more water comes out.

Step 5: Remove and Inspect the Filter

Once the water has drained, unscrew and remove the filter completely.

You may find:

Lint
Hair
Coins
Buttons
Small pieces of fabric
Paper or tissues
Other trapped debris

Remove all visible material by hand while wearing gloves.

Step 6: Clean the Filter Thoroughly

Rinse the filter under warm running water.

Use an old toothbrush or small cleaning brush to scrub around the grooves and reach areas where dirt has accumulated.

Avoid using excessive force, as some filter parts are made from plastic and may become damaged.

Step 7: Clean the Filter Housing

Use a damp cloth to wipe the opening where the filter sits.

Carefully check inside for any remaining debris. Depending on the model, you may also be able to see the small pump impeller at the back of the compartment.

It should move slightly when gently touched, but never force it. If it appears jammed or damaged, consult a qualified appliance technician.

Avoid pouring large amounts of water directly into the filter housing unless the manufacturer specifically recommends doing so.

Step 8: Reinstall the Filter

Place the clean filter back into its housing and turn it clockwise until it is secure.

Do not overtighten it, but make sure it is properly sealed to prevent leaks.

Close the access panel and wipe the surrounding area dry.

Step 9: Run a Short Test Cycle

Reconnect the washing machine and run a short rinse or drain cycle without clothes.

Watch the filter area carefully to make sure there are no leaks.

If water appears around the filter, stop the machine, unplug it, and check whether the filter has been installed correctly.

Don’t Forget the Detergent Drawer

The detergent drawer can also collect soap residue, fabric softener, mold, and stagnant water.

Remove the drawer according to the manufacturer’s instructions and soak it in warm, soapy water.

Scrub the compartments with a toothbrush, rinse thoroughly, and allow the drawer to dry before reinstalling it.

Also wipe the cavity where the drawer sits, as residue often builds up in this hidden area.

Be Careful with Dishwasher Tablets

Some household tips recommend dissolving a dishwasher tablet to clean the detergent drawer.

Although this may remove stubborn residue, dishwasher detergents are highly concentrated and are not designed for every washing-machine component. They may irritate the skin or damage certain finishes.

Warm water and dish soap are usually sufficient for routine cleaning. For stubborn buildup, use a product approved by the washing-machine manufacturer.

How to Use Laundry Capsules Properly

Laundry capsules can leave residue when they do not dissolve completely. However, this does not mean they must always be used above 40°C.

Modern capsules are generally designed to dissolve at lower temperatures, but problems can occur when:

The drum is overloaded
A very short cycle is selected
The capsule is placed in the detergent drawer
The capsule becomes trapped between clothes
Too many capsules are used
Water pressure is low

Place the capsule at the back of the empty drum before adding clothes. Follow the dosage and temperature instructions printed on the product packaging.

If residue repeatedly remains on clothing, consider switching to liquid or powdered detergent.

How Often Should You Clean the Filter?

The ideal schedule depends on how often the machine is used.

For most households, inspect the filter approximately every one to three months. Check it more frequently if you wash pet bedding, heavily soiled clothes, or garments that release a lot of lint.

You should also inspect the filter when:

The machine stops draining properly
Clothes remain unusually wet
You hear rattling during drainage
The appliance develops a persistent odor
A drainage error appears

Additional Washing Machine Maintenance Tips

To keep the appliance fresh and working properly:

Check pockets before every wash.
Avoid overloading the drum.
Use only the recommended amount of detergent.
Leave the door slightly open after washing.
Wipe the rubber door seal regularly.
Remove wet laundry promptly.
Clean the detergent drawer frequently.
Run a manufacturer-approved maintenance cycle when needed.
Check the drainage hose for bends or blockages.

Important Safety Reminder

Always unplug the washing machine before cleaning the filter.

Never open the filter while the machine is running or while the drum contains hot water. Follow the instructions in your appliance manual, as filter designs and drainage procedures vary between manufacturers.

If the filter cannot be removed, the machine continues leaking, or the pump makes abnormal noises, contact a qualified technician.

Final Thoughts

A simple plastic bottle can make washing-machine filter cleaning far less messy.

By guiding trapped water into a container, the bottle helps protect your floor while you remove lint, coins, hair, and other debris from the filter.

Cleaning this small component regularly can improve drainage, reduce unpleasant odors, and help your washing machine perform reliably for longer.
