How do I clean a dishwasher filter?
Step-by-step cleaning
Most dishwashers have a cylindrical or flat filter at the bottom of the tub. Twist it counterclockwise or lift it straight up to remove it, depending on your model. Check your manual if it doesn't budge.
Rinse the filter under warm running water to remove loose food particles. Use a soft brush (an old toothbrush works well) and a drop of dish soap to scrub away grease and stuck-on bits. Avoid abrasive pads that can scratch the mesh.
For stubborn buildup, soak the filter in a mixture of equal parts white vinegar and warm water for 10–15 minutes, then rinse thoroughly. Reinstall the filter by reversing the removal steps and make sure it locks into place.
- Remove the bottom rack for easier access.
- Twist or lift out the filter—don't force it.
- Rinse away loose debris first.
- Scrub with a soft brush and dish soap.
- Soak in vinegar solution if greasy.
- Reinstall and lock the filter securely.
How often to clean
Aim to clean the filter at least once a month. If you run your dishwasher daily or often wash greasy dishes, clean it every two weeks. Some newer models have a self-cleaning filter that still needs occasional manual rinsing.
Signs it's time to clean: dishes come out gritty, water pools at the bottom, or you notice a bad odor. Regular cleaning also helps your dishwasher last longer and clean better.
Common mistakes
- Putting the filter in the dishwasher—most are not dishwasher-safe and can warp.
- Using harsh chemicals like bleach, which can damage plastic parts.
- Forgetting to reinstall the filter, which can clog the pump and cause leaks.
