Clean dishwasher filter

Clean your dishwasher filter to restore cleaning performance and prevent odors.

Why it matters#

A clogged filter is the most common cause of dishes coming out dirty or gritty. Regular cleaning keeps your dishwasher working efficiently.

What you'll need#

Materials#

Dish soap
Warm water
Clean cloth or sponge

Steps#

1. Empty the dishwasher#

Remove all dishes and pull out the bottom rack to access the filter area on the floor of the dishwasher.

2. Locate the filter#

Look at the bottom center or back corner of the dishwasher. Most filters are cylindrical with a twist-off top or a flat mesh screen that lifts out.

3. Remove the filter#

For cylindrical filters: twist counter-clockwise and lift out. There may be a secondary flat filter underneath—remove that too. For flat filters: simply lift straight up.

4. Rinse under running water#

Hold the filter under warm running water to flush away loose debris and food particles.

5. Scrub with soapy water#

Apply a few drops of dish soap and use a soft brush to gently scrub the mesh. Work in circular motions to dislodge stuck particles. Avoid abrasive scrubbers that can damage the mesh.

6. Clean the filter housing#

While the filter is out, wipe around the filter housing with a damp cloth. Remove any debris or buildup you find.

7. Rinse thoroughly#

Rinse the filter under clean water until all soap is gone and the mesh looks clear.

8. Reinstall the filter#

Place the filter back in position. For cylindrical types, twist clockwise until it locks. Ensure it's seated properly—a loose filter won't catch debris.

Pro tips#

Clean the filter monthly for best performance, or more often if you don't rinse dishes before loading

Warnings#

Never use harsh chemicals or abrasive scrubbers on the filter mesh
A damaged filter should be replaced—torn mesh lets food particles recirculate onto dishes
Don't run the dishwasher without the filter in place

No professional needed for filter cleaning. However, if dishes remain dirty after cleaning the filter, the spray arms may be clogged or there could be a pump issue—consider calling an appliance repair service.
