Most people wipe down the exterior of their washing machine or run an occasional cleaning cycle, but there’s a small, hidden component that’s crucial for machine hygiene and fresh-smelling laundry: the drain pump filter. Appliance experts emphasize that cleaning this filter just once a month can prevent foul odors, improve washing performance, and extend the life of your machine.

What Is the Drain Pump Filter?

It’s a small, cylindrical filter—usually located behind a small access panel at the bottom front of your washing machine. Its job is to catch lint, hair, coins, small objects, and debris before water is pumped out of the drum.

Why Clean It Monthly?

When the filter becomes clogged:

Problem	Consequence
Stagnant water left in the filter area	Causes musty smells and mold growth
Poor drainage	Clothes come out soapy or damp
Bacteria buildup	Odors transfer to your laundry
Reduced efficiency	Machine works harder, may overheat

A clean filter ensures proper drainage, prevents mold, and keeps your drum—and clothes—fresh.
