How to Clean a Dishwasher Filter: Bosch, Whirlpool, GE, Samsung, LG & Frigidaire

A clean dishwasher filter is the secret to sparkling dishes and a longer-lasting appliance. Over time, food particles, grease, and soap residue can clog your dishwasher filter, reducing cleaning power and even causing unpleasant odors. The good news? Cleaning your filter is quick, easy, and doesn’t require special tools.

In this guide, we’ll walk you through how to clean the filter on several popular dishwasher brands and models.

Why Dishwasher Filters Need Cleaning

Modern dishwashers rely on filters to trap food debris and prevent it from redepositing on your dishes. When the filter gets clogged:

• Dishes come out cloudy or gritty.

• Water may pool at the bottom of the tub.

• The dishwasher can smell musty or sour.

• The pump and motor have to work harder, shortening their lifespan.

  
  

Experts recommend cleaning your filter at least once a month, or more often if you wash heavily soiled dishes.

General Steps to Clean a Dishwasher Filter

While each brand is a little different, here’s the basic process:

1. Turn off and empty the dishwasher.

2. Locate the filter. Usually found at the bottom of the tub, under the spray arm.

3. Remove the filter. Most twist out counterclockwise; some lift straight up.

4. Rinse under warm water. Use a soft brush or old toothbrush to scrub away debris.

5. Wipe the filter housing. Use a damp cloth to remove any gunk inside the dishwasher.

6. Reinstall the filter. Ensure it locks securely in place.

   
   

Now, let’s look at popular brands and models.

Frigidaire Dishwashers

• The filter is circular and located in the lower center.

• Twist and lift to remove.

• Many Frigidaire filters have fine mesh—be gentle when scrubbing.

  
  

Samsung Dishwashers

Pro Tips

• Avoid harsh cleaners: Don’t use bleach or strong chemicals—they can damage the mesh.

• Check spray arms too: If you’ve gone a long time without cleaning, food bits may also clog the spray arms.

• Re-seat carefully: An improperly installed filter can cause poor cleaning results or damage.
