Overview
If your dishwasher isn’t cleaning well, smells bad, or leaves residue on dishes, the filter is usually the problem. Food particles, grease, and soap buildup collect in the filter over time. The good news is that cleaning it takes only a few minutes and requires no special tools.
What You’ll Need
- Warm water
- Mild dish soap
- Soft brush or old toothbrush
- White vinegar (optional)
- Microfiber cloth
Step 1 — Remove the Bottom Rack
Pull out the bottom rack to access the filter. Most filters are located at the bottom center of the dishwasher. If you’re also cleaning nearby kitchen surfaces, see our guide on how to clean countertops.
Step 2 — Twist and Lift the Filter
Most dishwasher filters twist counterclockwise to unlock. Lift the filter straight out. If your dishwasher has a secondary mesh screen, remove that as well.
Step 3 — Rinse Under Warm Water
Rinse the filter under warm running water to remove loose debris. Use your fingers to dislodge food particles trapped in the mesh.
Step 4 — Scrub With Soap and a Brush
Apply a few drops of dish soap and scrub gently with a soft brush or old toothbrush. Pay attention to the mesh and edges where grease collects. For stubborn odors, soak the filter in a 1:1 vinegar and water solution for 10 minutes.
Step 5 — Clean the Filter Housing
Wipe the inside of the filter compartment with a microfiber cloth. Food particles often hide around the edges. If you’re dealing with kitchen grease elsewhere, see our guide on how to clean a greasy stove top.
Step 6 — Reinstall the Filter
Place the filter back into the housing and twist clockwise until it locks securely. Running the dishwasher without a locked filter can damage the appliance.
Step 7 — Run a Cleaning Cycle (Optional)
For extra freshness, place a cup of white vinegar on the top rack and run a hot cycle. This helps remove lingering odors and mineral buildup.
