How to Clean Your Dishwasher Filter (Step-by-Step)

renovated kitchen, with a new dishwasher

Let’s face it — most of us load the dishwasher, press start, and don’t think about what happens after. But over time, food particles, grease, and soap scum can build up in the filter, leaving your dishes less-than-sparkly and your dishwasher working harder than it should.

The good news? Cleaning your dishwasher filter is quick, easy, and something you can totally handle on your own (no tools required).

Here’s exactly how to do it — from your local Vaughan appliance repair pros at Best Appliance Repairs.

Why Cleaning the Filter Matters

If your dishwasher’s been smelling funky, leaving residue on glasses, or making weird noises mid-cycle, the filter might be to blame.

Over time, buildup in the filter can lead to:

  • Poor cleaning performance

  • Drainage problems

  • Musty or sour smells

  • Extra wear and tear on the motor

And the worst part? It’s totally avoidable with just a little maintenance.

Step-by-Step: How to Clean Your Dishwasher Filter

Step 1: Open the Bottom Rack and Locate the Filter

Start by pulling out the bottom rack so you have a clear view of the floor of the dishwasher. Look in the back corner or right in the center — most filters twist out with a quick turn counterclockwise.

  • Not sure where yours is? Check your owner’s manual or search the model number online.

Step 2: Remove the Filter Gently

  • Once you locate the filter, give it a gentle twist and lift it out. Some models have a mesh screen and a cylindrical filter — remove both if possible.

  • Be careful not to force it. If it feels stuck, it might just be a buildup of grime. (Gross, but fixable.)

Step 3: Soak and Scrub

Fill your sink or a large bowl with warm, soapy water. Let the filter soak for a few minutes to loosen up grease and gunk.

  • Use a soft brush or old toothbrush to scrub away buildup.

  • Avoid anything abrasive like steel wool — it could damage the mesh.

Pay attention to the crevices — food bits love to hide there.

Step 4: Wipe the Inside of the Filter Area

While the filter is out, grab a damp cloth or sponge and wipe around the inside of the filter housing. You might find slimy residue or hidden food bits there too.

No need for harsh chemicals — warm water and a little dish soap do the trick.

Step 5: Reinstall the Filter

Once it’s clean and dry, pop the filter(s) back in place. Make sure it’s seated properly and locked in — otherwise, your dishwasher might not run correctly.

That’s it! You’re done in under 10 minutes, and your dishes (and nose) will thank you.

How Often Should You Clean the Filter?

For most homes, once a month is ideal.
If you run your dishwasher daily or often skip rinsing food off dishes, clean it every 2–3 weeks.

Bonus tip: Always rinse heavy food debris off plates before loading the dishwasher. Your filter (and your drain) will last longer.
