How to Clean Dishwasher Filter (Simple & Effective Method)

What Is a Dishwasher Filter and Why It Matters

The dishwasher filter traps food particles, grease, and debris so they don’t clog the drain or get sprayed back onto dishes. Over time, this buildup can cause:

• Poor cleaning results

• Standing water at the bottom

• Bad odors

• Drainage problems

Regular filter cleaning prevents these issues.

Where Is the Dishwasher Filter Located?

Most dishwasher filters are located:

• At the bottom of the dishwasher tub

• Under the lower spray arm

You usually need to remove the bottom rack to access it.

How to Clean a Dishwasher Filter (Step by Step)

Step 1: Turn Off the Dishwasher

For safety, make sure the dishwasher is turned off. You don’t need to unplug it, but ensure it’s not running.

Step 2: Remove the Bottom Rack

Slide out the lower rack completely to expose the filter area.

Step 3: Take Out the Filter

Most modern dishwashers have a twist-lock filter.

• Turn the filter counterclockwise

• Lift it straight out

Some models have two parts: a cylindrical filter and a flat mesh screen.

Step 4: Rinse the Filter

• Rinse under warm running water

• Remove loose food particles

Avoid using very hot water if the filter is plastic.

Step 5: Scrub Gently

• Use a soft brush or old toothbrush

• Add a few drops of dish soap

• Scrub grease and stuck-on debris

Do not use steel wool or hard brushes. They can damage the filter mesh.

Step 6: Clean the Filter Housing

Before reinstalling:

• Wipe the area where the filter sits

• Remove food or debris from the sump

This helps improve drainage.

Step 7: Reinstall the Filter

• Place the filter back into position

• Twist clockwise until it locks firmly

Make sure it’s seated correctly. A loose filter can cause noise or poor cleaning.

How Often Should You Clean a Dishwasher Filter?

• Once a week: If you don’t rinse dishes before loading

• Every 2–4 weeks: If dishes are mostly pre-rinsed

• Immediately: If you notice odors or standing water

Regular cleaning prevents major dishwasher problems.

What Not to Do When Cleaning a Dishwasher Filter

These can damage the filter and reduce its lifespan.

Extra Tips to Keep Your Dishwasher Clean

• Scrape food off dishes before loading

Cleaning your dishwasher filter is one of the easiest ways to improve performance and prevent costly repairs. It takes less than 10 minutes and can solve common issues like bad smells, dirty dishes, and drainage problems.
