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

The Hidden Part of Your Dishwasher

Most people don’t realize that dishwashers have filters — and that those filters need to be cleaned regularly. When they’re neglected, they can quietly affect how well your dishwasher works, how your dishes come out, and even how long the machine lasts.

Cleaning your dishwasher filter is a small home maintenance task, but it has a surprisingly big impact.

What Is a Dishwasher Filter (and Why It Matters)

A dishwasher filter sits at the bottom of the machine and is designed to trap food debris, grease, and particles so they don’t redeposit on your dishes or clog the drain.

When the filter is dirty, it can lead to:

• Unpleasant smells

• Grit or residue left on dishes

• Poor cleaning performance

• Extra strain on the dishwasher over time

Keeping the filter clean helps your dishwasher run more efficiently and last longer.

How Often Should You Clean Your Dishwasher Filter?

A good general guideline is:

• Every 1–3 months for most households

• Monthly if you run your dishwasher frequently

You may need to clean it more often if:

• You don’t pre-rinse dishes

• You have a large household

• You cook frequently or from scratch

Signs your filter needs cleaning:

• A musty or sour smell

• Grit or debris on clean dishes

• Standing water at the bottom of the dishwasher

  
  

Dishwasher Filters Often Have Two Parts

Many dishwashers actually have two filter components:

• A cylindrical mesh filter

• A flat filter plate underneath

The flat piece is easy to miss, but it’s just as important. Food and grease often collect between the two layers, so if you’re only cleaning the removable cylinder, you’re only doing half the job.

How to Clean a Dishwasher Filter (Step by Step)

Step 1: Remove Both Filter Pieces

Remove the bottom rack.

Twist and lift out the cylindrical filter, then carefully remove the flat filter underneath.

Set both aside.

This is the main filter part.

Don't forget the second filter part

Step 2: Rinse Off Debris

Rinse both pieces under warm running water. A steady stream is usually enough to dislodge trapped food particles. Avoid harsh tools or forceful spraying that could damage the mesh.

Step 3: Deep Clean If Needed

If there’s greasy buildup:

• Add a drop of dish soap

• Use a soft brush or toothbrush

• Soak briefly in warm water with a splash of vinegar if needed

Rinse thoroughly once clean.

A strong jet is often enough to dislodge particles.

The filter should be thoroughly cleaned before being put back in place.

Rinse the second filter part as well.

Step 4: Reinstall the Filter Correctly

Make sure both pieces are fully clean and locked back into place. A loose or misaligned filter can affect dishwasher performance.

Common Mistakes to Avoid

• Using harsh chemicals

• Running the dishwasher without the filter

• Forgetting to clean the surrounding area

  
  

How This Fits Into a Simple Cleaning Routine

Cleaning your dishwasher filter fits easily into a regular home maintenance routine. It’s a great task to pair with a monthly fridge clean-out, refreshing your sink drains, or doing a seasonal reset around the house. Bundling small, quick tasks together like this makes home maintenance feel far more manageable and helps prevent bigger issues down the line.

This is one of those small habits with a big payoff. A clean dishwasher filter means cleaner dishes, a fresher-smelling kitchen, and a longer-lasting appliance.

If you’re already cleaning your home, this is one task that shouldn’t be skipped.
