Many people clean the outside of their washing machine regularly, but few realize that inside the machine is a small, often-overlooked part that plays a crucial role in hygiene. Appliance experts say opening and cleaning this component just once a month can significantly improve washing performance and eliminate unpleasant odors.

The Small Part Most People Forget

That part is the drain pump filter (also called the lint or debris filter). It is usually located at the bottom front of the washing machine, behind a small cover. Its job is to trap lint, hair, coins, buttons, and other debris before water is drained out.

Over time, this filter can become clogged with dirt, detergent residue, and stagnant water — creating the perfect environment for bacteria and mold.

Why You Should Clean It Monthly

When the filter is dirty:

• The washing drum may develop a musty smell

• Clothes can come out less clean or with odors

• Bacteria and mold can build up inside the machine

• Water drainage becomes less efficient

Cleaning the filter regularly helps keep the drum clean, improves water flow, and ensures your laundry smells fresh after every wash.

How to Clean It Safely

Experts recommend these simple steps:

1. Turn off the washing machine and unplug it

2. Open the small cover at the bottom front

3. Place a towel or shallow tray underneath to catch water

4. Slowly unscrew and remove the filter

5. Rinse it thoroughly under running water

6. Wipe the filter housing clean before reinstalling

The entire process usually takes less than 5 minutes.

Extra Tips for a Fresher Washing Machine

• Leave the washing machine door slightly open after use

• Avoid using too much detergent

• Run a hot empty cycle with vinegar or a machine cleaner once a month

The Bottom Line

A clean washing machine starts with attention to the small details. Opening and cleaning this tiny filter once a month can keep your washing drum hygienic, extend the life of your machine, and ensure your clothes always come out clean and pleasantly fresh.
