How to Clean a Washer Drain Pump Filter Safely

Why this maintenance matters

• Lint, coins, buttons, hair, small fabric items, and detergent residue can collect in a user-accessible pump filter.
• A clogged filter can restrict drainage and contribute to standing water or odor.
• A loose filter cap or residual-water hose cap can leak after cleaning.
• A clean filter does not rule out a restricted drain hose, household drain issue, pump fault, wiring issue, or control problem.

Safe steps in order

1. 1

   Confirm your washer actually has a user-serviceable filter

   • Find the exact model number and owner manual before opening anything.
   • If the manual does not show an access door and cleaning procedure, do not remove panels or assume a hidden filter is owner-serviceable.
2. 2

   Power off, cool down, and prepare for water

   • Turn the washer off and unplug it when the manufacturer procedure directs. Empty the drum.
   • If a hot or sanitize cycle just ran, wait until the water has cooled. Samsung specifically warns that residual water can be hot enough to burn.
   • Place towels and a shallow pan at the access door because residual water can release suddenly.
3. 3

   Drain residual water using the model procedure

   • If the washer has a small residual-water hose, pull out only the amount shown in the manual and drain it into a shallow pan before removing the filter.
   • Do not yank or overextend the hose. LG warns that pulling it too far can kink it.
4. 4

   Remove only the documented pump filter

   • Turn or release the filter exactly as the manual shows. Expect a small amount of additional water.
   • Stop if the cap is seized, cracked, unusually hard to turn, or access requires removing a service panel.
5. 5

   Clean the filter gently

   • Remove visible lint, coins, buttons, hair, and debris. Rinse with warm water and use a soft brush or sponge when the manufacturer allows it.
   • Do not use knives, wire brushes, drain chemicals, compressed air, or power tools.
6. 6

   Inspect the accessible opening without reaching deeper

   • Wipe only what is clearly reachable at the filter seat. Do not put fingers into an unseen pump cavity or force an impeller.
   • If sharp debris, damaged plastic, or an obstruction is beyond the owner-accessible area, stop and request service.
7. 7

   Reinstall, close, and test for leaks

   • Reinstall the filter squarely and securely, replace the residual-water hose cap, return the hose, and close the access door.
   • Run one short rinse/drain test while watching the filter area. Stop immediately if water appears around the cap or access door.
