How to Clean Your Washing Machine Drain Filter (Step-by-Step)
A clogged drain filter is the #1 cause of washer drain errors. This guide shows you exactly how to clean it on front-load and top-load washers.
Why Cleaning the Drain Filter Matters
The drain pump filter captures lint, coins, buttons, and other debris before they can reach the pump impeller. When it gets clogged, the machine can't drain properly — resulting in OE, E18, F9E1, 5E, and similar error codes.
Most manufacturers recommend cleaning the filter every 1–3 months.
Step 1: Gather Your Supplies
Step 2: Locate the Filter
On most front-load washers, the filter is behind a small access panel on the lower-front of the machine. On some models it's at the end of a short drain hose inside the same panel.
Step 3: Drain Residual Water
Place your pan under the access panel. Open the panel and slowly loosen the filter cap (counterclockwise) — water will flow out. Let it drain completely before removing the filter.
Step 4: Remove and Clean the Filter
Pull out the filter and remove all debris — lint, hair, coins, etc. Rinse under running water and scrub with an old toothbrush if needed.
Step 5: Reinstall and Test
Screw the filter back in firmly (hand-tight). Close the access panel. Run a short rinse cycle to confirm the code is cleared.
Maintenance Tip
Set a monthly reminder to check the filter. A 5-minute cleaning now prevents a service call later.
