To clean a Whirlpool dishwasher filter, remove the lower rack, take out the removable filter parts as your model's manual directs, and rinse them under running water. Reinstall each part securely before running the dishwasher.

Filter designs and removal steps vary by model, so check your owner's manual before twisting or lifting anything. Whirlpool provides manuals and literature by appliance model number.

How do you clean a Whirlpool dishwasher filter?

Rinse the removable filter parts under running water and clear loose debris gently. Use the removal and reinstallation steps for your exact model.

1. Turn off the dishwasher and let the interior cool if it has just run.
2. Pull out the lower rack to reach the filter area.
3. Remove the filter parts as your manual shows. Some models use a twist-lock filter; don't force a part that won't turn or lift.
4. Rinse off food particles and buildup. Use a soft brush only if your manual permits it.
5. Check the filter and its surrounding area for damage or debris.
6. Reinstall the parts in the correct position and secure them as directed.
7. Return the lower rack and run a cycle if you want to check that the dishwasher operates normally.

Don't use a knife, screwdriver, or other sharp tool to scrape the filter. If a part is stuck, stop and check the model's instructions rather than applying force.

For broader cleaning steps, see how to clean a dishwasher. If you need a general filter overview, our guide to how to clean a dishwasher filter covers the basic process.

How can you tell which filter parts your Whirlpool model has?

Use the model number to identify the filter parts and removal method. Look for the number on the appliance label, then find the matching manual.

Don't assume every Whirlpool dishwasher uses the same filter. The manual can show whether the filter lifts out, twists to release, or has multiple pieces that must be removed in a certain order.

If food remains on dishes after cleaning, inspect the filter for visible debris and check that it sits correctly. Also check the spray arms for blocked openings; our guide explains how to clean dishwasher spray arms.

What if the filter is damaged?

Replace a damaged filter only after confirming the replacement fits your model. Part numbers can apply to specific models and aren't universal across Whirlpool dishwashers.

The eHuangTools 645038 drain mesh is described for some specific dishwasher models and replacement part numbers. Its stated compatibility includes Bosch model numbers, so don't assume it fits a Whirlpool appliance; verify your exact model before considering it.

A filter that is merely dirty usually needs cleaning, not replacement. If it is cracked, warped, or won't stay in place, use the model manual or contact Whirlpool support to identify the right part.

Are W10872845 filter cups right for a Whirlpool dishwasher?

Some W10872845 filter cups are described as compatible with certain Whirlpool models, but the part number alone doesn't confirm a fit. Check your dishwasher's model and existing part number before ordering.

The Cenipar W10872845 filter cup is described as washable and compatible with Whirlpool and Kenmore dishwashers. Its listed replacement numbers include W10056425 and W10056426, among others.

AMI PARTS also offers a W10872845 filter cup described for certain Whirlpool, Kenmore, Amana, and KitchenAid dishwashers. Its guidance says to compare the filter cup's shape and locking-tab orientation before ordering.

These are replacement parts, not cleaning tools. Don't remove a working filter to install a replacement unless the old part is damaged or your manual calls for it.

What should you do if the filter area still looks dirty?

Remove only debris you can reach safely, then follow the manual for cleaning the filter area. Don't pour cleaner into the sump or reach into hidden openings unless the instructions allow it.

A filter rinse won't clear every part of the dishwasher. Check the spray arms and interior for visible food buildup, and make sure the filter is seated after cleaning.

For a separate cleaning method, read how to clean a dishwasher with vinegar. Follow your Whirlpool manual first, especially if it gives specific cleaning-product guidance.

What if the dishwasher still drains poorly?

A clean filter doesn't rule out a blockage elsewhere. Check your manual for any safe drain-area checks, and stop if the instructions require removing panels or reaching into the pump.

For countertop models, the hose is a separate part of the drain path; see how to clean a countertop dishwasher drain hose. If your built-in Whirlpool continues to hold water or shows an error, contact Whirlpool support or a qualified repair technician.

How often should you clean the filter?

Use the cleaning schedule in your Whirlpool manual, and inspect the filter when you notice visible buildup. Food particles and heavy use can make an earlier rinse useful.

After cleaning, check that the filter is secured and the lower rack moves freely. If the same debris or draining issue returns quickly, the cause may be elsewhere in the dishwasher.

For a Whirlpool owner deciding what to do next, clean a removable filter when it is dirty, and replace it only when it is damaged and the part is confirmed to fit. If cleaning doesn't improve drainage, check the manual's troubleshooting steps or contact Whirlpool support.

Frequently asked questions

How often should I clean a Whirlpool dishwasher filter?

Check and clean the filter as often as your Whirlpool owner's manual recommends. If you see food buildup or notice dishes aren't coming out clean, inspect it sooner.

Rinse away debris without using tools or cleaners that the manual says to avoid, and make sure the filter is seated correctly afterward.

Can I run a Whirlpool dishwasher without its filter?

Don't run the dishwasher without its filter or with a filter that isn't locked into place. The filter helps keep food debris from moving through the wash system.

Check your model's manual for removal and installation steps, and replace a damaged filter only with a part confirmed to fit your exact model.

Why is my Whirlpool dishwasher still not draining after I clean the filter?

A clean filter may not resolve a drain problem if debris is elsewhere or another part needs attention. Check the manual for the drain area and hose steps, and don't reach into areas you can't see or safely access.

If the problem continues, contact Whirlpool support or a qualified repair technician.
