How to Clean Inside the Dishwasher Filter

Tools:

- E-Cloth
- Soft brush (such as an old toothbrush)
- Warm running water
- Dish soap
- Small bowl or basin

Remove the Filter

Open your dishwasher and locate the filter at the bottom. If you're not sure where it's hiding, a quick peek at the manual might help.
Gently lift the filter out—no brute force needed. It should come out fairly easily.

Rinse Off Loose Debris

Hold the filter under warm running water to wash away food particles and buildup.
If some stubborn gunk sticks around, give it a gentle scrub with a soft brush.

Shake and Inspect

After rinsing, give the filter a little shake to dislodge any remaining debris.
Double-check that it’s clean and free of buildup before placing it back in the dishwasher.

Safety Precautions

Unplug or turn off the dishwasher at the circuit breaker before starting to avoid accidental activation.
Wait until the dishwasher is cool—never clean the filter right after a cycle, as hot water and steam can cause burns.
Wear rubber gloves to protect your hands from sharp debris and cleaning agents.
Handle the filter gently to avoid damaging delicate mesh or plastic parts.
Do not use harsh chemicals or abrasive tools; stick to a soft brush and mild soap if needed.
Ensure the filter is completely dry before reinstalling to prevent mold growth.

How to Maintain Cleanliness Inside the Dishwasher Filter: Extra Tips

Regular Rinsing of the Filter

Quick Removal: Take out the dishwasher filter at least once a week to remove food particles and grease buildup.
Rinse Thoroughly: Use warm water to rinse off loose debris. Avoid using harsh chemicals that might damage the filter.

Title

Soak in Warm Soapy Water

Deep Cleaning: Soak the removed filter in warm water mixed with a few drops of dish soap for about 10-15 minutes.
Gentle Scrub: Use a soft brush or an old toothbrush to gently scrub the mesh and surrounding areas.

Title

Inspect and Clean Hidden Areas

Spot-Check: Look for stubborn grease or debris near the edges and corners of the filter.
Use a Toothpick: Carefully remove any clogging particles using a toothpick or a similar tool.

Reassemble and Run an Empty Cycle

Proper Reinstallation: Ensure the filter is fully dry and properly reinserted into your dishwasher.
Empty Cycle: Run an empty cycle with a dishwasher cleaner or a cup of white vinegar to clear any remaining residue.

Common Mistakes When Cleaning Inside the Dishwasher Filter

Don't Skip Pre-Cleaning: Remove Large Debris

Leaving clumps of food or gunk in the filter can clog the system and reduce cleaning performance.
Make sure to manually knock off or gently rinse away visible particles before starting a cycle.
This step prevents odors and buildup that could lead to permanent damage.

Avoid Harsh Chemicals and Improper Tools

Using abrasive brushes or strong chemical cleaners can damage the delicate mesh and plastic parts of the filter.
Opt for soft brushes and mild detergents to maintain the filter’s longevity.
Harsh treatments may leave residues or scratches that impede proper water flow.

Don't Wait Too Long Between Cleanings

Infrequent maintenance allows buildup to become stubborn, making thorough cleaning harder.
Schedule regular checks to remove light residues and food particles before they harden.
Regular maintenance helps preserve optimal dishwasher performance and extends the filter's life.

How Often to Clean Inside the Dishwasher Filter

Cleaning Frequency for Your Dishwasher Filter

Monthly Check: For most households, cleaning the dishwasher filter once a month strikes the perfect balance. Regular monthly maintenance prevents stubborn food buildup and keeps the dishwasher running efficiently.
Heavy Use Considerations: If your household runs the dishwasher frequently or you often cook meals that result in greasy residue, consider inspecting and cleaning the filter more often. This additional check can help avoid odor issues and lower cleaning performance.
Long-Term Benefits: Sticking to a monthly routine avoids the risk of clogged filters that can reduce water flow and lead to potential mold accumulation. A clean filter means your dishwasher can do its job without extra strain, helping extend its lifespan.
