The filter is at the bottom of your KitchenAid dishwasher, under the lower spray arm

Your KitchenAid dishwasher has a removable filter assembly located on the floor of the tub, directly beneath where the lower spray arm rotates. It looks like a cylindrical or basket-shaped cage, usually made of plastic or stainless steel. On most KitchenAid models, you'll see it when ready when you open the door and look down—it's not hidden behind panels or removable parts.

The filter traps food particles, grease, and debris so they don't recirculate onto your dishes or clog the spray arm holes. Because it catches everything, it needs regular cleaning to work properly. A clogged filter forces water to back up in the tub, leaving dishes wet or spotted, and can eventually damage the pump.

Key Takeaways

  • The filter sits on the floor of the dishwasher tub, directly under the lower spray arm, and is visible when you open the door.
  • Most KitchenAid filters twist counterclockwise to remove; some models have a handle or tab you pull straight up.
  • Rinse the filter under running water after every few loads, and soak it in hot water if food is stuck to the mesh.
  • Never run the dishwasher without the filter in place, as debris will damage the pump and spray arm.
  • If water pools at the bottom of the tub after a cycle, the filter is likely clogged and needs cleaning.

How to remove the filter from your KitchenAid

The removal method depends on your model, but most KitchenAid dishwashers use one of two designs. Open the door, pull out the lower rack, and look at the filter assembly on the tub floor. If it has a handle or knob on top, grip it firmly and twist counterclockwise until it stops, then lift straight up. If it has a tab or pull-handle instead, grasp that and pull straight up—no twisting needed.

Some newer KitchenAid models have a two-part filter: an upper cylindrical cage that twists out, and a lower flat screen underneath. If you see two pieces, remove the upper cage first by twisting, then lift out the flat screen below it. Check your model number in your owner's manual if you're unsure which type you have—the manual will show the exact removal steps with photos.

Once the filter is out, hold it over the sink and rinse it under warm running water, rubbing the mesh with your fingers to dislodge trapped food. If debris is baked on or the mesh looks dark, soak the filter in hot water for 10 to 15 minutes, then scrub gently with an old toothbrush. Never use a dishwasher or high-pressure spray, as that can damage the fine mesh.

Reinstalling the filter correctly

After cleaning, slide the filter back into the opening on the tub floor. Make sure it sits flat and level—it should not rock or tilt. If your model twists to lock, turn the handle clockwise until it stops; you'll feel resistance, but do not force it. If it has a pull-handle, it should drop into place with no twisting required.

Close the door and run a short rinse cycle (no dishes) to check that water drains properly. If water pools at the bottom after the cycle ends, the filter may not be seated correctly. Open the door, remove the filter, and reinstall it, making sure it's fully seated and locked in place.

When to clean the filter and what to watch for

Clean the filter every two to four weeks if you run the dishwasher regularly, or after every few loads if you wash heavily soiled dishes. Rinse it more often if you notice water not draining, dishes coming out wet, or a musty smell inside the tub. These are all signs the filter is clogged and restricting water flow.

If you see grease buildup that won't rinse away, soak the filter in a mixture of hot water and a few drops of dish soap for 15 minutes, then scrub with a soft brush. Never use abrasive scrubbers or bleach, as these can scratch or degrade the mesh. If the mesh is torn, cracked, or has holes, the filter must be replaced—a damaged filter will let debris into the pump.

What happens if you run the dishwasher without the filter

Never operate your KitchenAid without the filter in place. Without it, food particles and grease flow directly into the pump and spray arm, where they can jam the moving parts or block the spray holes. This damage is expensive to repair and is not covered by warranty because it results from user error, not a defect.

If the filter is missing or you've removed it for cleaning, always reinstall it before starting a cycle. If you've lost the filter or it's damaged beyond repair, order a replacement from KitchenAid using your model number. The part typically costs between $20 and $50 and takes a few days to arrive.

Finding your model number and ordering a replacement filter

Your KitchenAid model number is printed on a label inside the door edge or on the side wall of the tub. It usually starts with "KDFE" or "KDTE" followed by numbers. Write this number down and search for it on the KitchenAid website or call their parts line to order the correct filter for your machine.

You can also contact a local appliance parts supplier with your model number, or search online retailers. Installation is straightforward—straightforward drop the new filter into the opening and lock or seat it the same way you would the old one. Keep the old filter until the new one arrives, so you can still use the dishwasher if needed.

Frequently Asked Questions

Can I put the filter in the dishwasher to clean it?

No. The high heat and spray pressure of a dishwasher cycle can damage the fine mesh and warp the plastic frame. Always rinse it by hand under warm running water and soak it if needed.

Why is there standing water at the bottom of my tub after a cycle?

The most common cause is a clogged filter. Remove it and rinse thoroughly under running water, rubbing the mesh to clear trapped food. If water still pools after reinstalling a clean filter, the drain hose or pump may be blocked—contact a service technician.

How do I know if my filter needs to be replaced instead of cleaned?

If the mesh has visible tears, holes, or cracks, or if it's warped and no longer sits flat, it must be replaced. A damaged filter will allow debris to reach the pump. If cleaning doesn't restore water drainage, replacement may also be necessary.

Is there a filter in the door or spray arm I should clean too?

Some KitchenAid models have small screens in the spray arm holes or inlet ports, but these are not user-serviceable. Focus on the main filter assembly at the bottom of the tub. If you suspect a clog elsewhere, consult your owner's manual or contact KitchenAid support.

What should I do if the filter won't twist out?

Do not force it—you may crack the frame. Make sure you're turning counterclockwise, not clockwise. If it still won't budge, soak the filter in hot water for 10 minutes to soften any stuck debris, then try again with a firm, steady grip. If it remains stuck, contact a service technician.
