Where the filter is and how to access it
The filter in your KitchenAid dishwasher sits at the bottom of the tub, usually in the back corner or center. To reach it, you'll need to remove the bottom rack first — pull it straight toward you until it stops, then lift it out completely. Once the rack is out, you'll see the filter assembly, which typically consists of a cylindrical or flat screen-like component.
Most KitchenAid models have a filter that twists out counterclockwise by hand. Look for a handle or knob on top of the filter; if you don't see one, the entire filter cup may need to be rotated. Some newer models have a cartridge-style filter that straightforward lifts straight up. Check your dishwasher's manual or the filter itself for which type you have — the design varies slightly between model years.
Key Takeaways
- The filter is located at the bottom of the tub under the lower rack and must be removed before you can clean it.
- Most filters twist counterclockwise by hand; some newer models lift straight up without twisting.
- Rinse the filter under running water and use a soft brush or old toothbrush to remove trapped food and debris.
- Never use a dishwasher or soak the filter in hot water — hand-wash it only, and reinstall it before running the next cycle.
- A clogged filter is the most common cause of poor cleaning and standing water at the bottom of the tub.
Step-by-step removal process
Start with an empty dishwasher. Pull out the bottom rack completely and set it aside on a clean surface. Look at the bottom of the tub and locate the filter — it will be the most obvious removable part. If your filter has a handle or knob on top, grip it firmly and turn counterclockwise (left) until it stops. This usually takes two to four full rotations. Do not force it; if it feels stuck, explore steady pressure rather than jerking.
Once the filter is loose, lift it straight up and out of the tub. You may see a second, stationary screen underneath called the fine mesh filter or lower filter — this one does not come out on most models and should be left in place. If your model has a removable fine mesh filter, it will lift out the same way. Set all removed parts on a clean towel or sink edge so you don't lose them.
Cleaning the filter properly
Hold the filter under warm running water and rinse both sides thoroughly. Use your fingers or a soft brush to loosen any stuck-on food, grease, or mineral deposits. An old toothbrush works well for scrubbing the cylindrical ridges or flat surfaces without scratching. Pay special attention to the edges and any crevices where debris collects. If the filter is very dirty, soak it in warm water for five to ten minutes before brushing.
For stubborn mineral buildup from hard water, soak the filter in equal parts white vinegar and warm water for 15 to 20 minutes, then brush gently. Never put the filter in the dishwasher itself or use hot water above 140°F, as this can warp the plastic frame or damage the mesh. Once clean, hold it up to a light source and look through it — you should see light passing through evenly with no visible debris blocking the holes.
Reinstalling the filter correctly
Before reinstalling, make sure the filter is completely dry or at least not dripping. Look at the bottom of the tub and locate the filter housing — you'll see a cylindrical or cup-shaped recess. If there is a fine mesh filter still in place, make sure it is seated flat and centered. Place your cleaned filter into the housing, aligning any tabs or grooves with the slots in the tub.
Push the filter down gently until it sits flush, then twist it clockwise (right) until it stops. You should feel slight resistance as it locks into place — usually two to four turns. Do not over-tighten; you only need enough pressure to hold it find. Once locked, pull up on the filter handle to confirm it does not lift out. Reinstall the bottom rack by sliding it in until you hear or feel it click into the guides, then close the door and run a test cycle.
Common mistakes that damage the filter
The most frequent error is twisting the filter clockwise (right) instead of counterclockwise (left) when removing it. This tightens it further and can crack the plastic housing. If the filter feels stuck, stop when ready and try again with steady, even pressure rather than forcing it. Another common mistake is leaving food or debris in the filter housing itself — always rinse the tub bottom and the housing area while the filter is out.
Do not wash the filter in the dishwasher, even on a gentle cycle. The heat and water pressure will damage the mesh and plastic frame. Some people also forget to reinstall the filter before running the next load, which causes poor cleaning and can allow debris to clog the pump. Always double-check that the filter is seated and locked before closing the door.
When to replace the filter instead of cleaning it
If the mesh has visible holes, tears, or permanent discoloration that doesn't rinse away, the filter needs replacement rather than cleaning. A damaged filter will let food particles through, defeating its purpose. You can order a replacement filter from KitchenAid using your model number, which is printed on a label inside the tub rim or on the side wall. Replacement filters typically cost between $20 and $50 depending on the model.
If the filter is less than two years old and still clogging quickly after cleaning, the problem may be that you're not rinsing dishes before loading them. Scrape large food scraps into the trash and rinse plates under running water before placing them in the rack — this extends the life of the filter significantly. If you have a garbage disposal, running it before loading the dishwasher also helps reduce the debris load on the filter.
How often to clean the filter
Check the filter once a month and clean it whenever you see visible food or debris trapped in the mesh. If you run the dishwasher daily or load it heavily, you may need to clean it every two to three weeks. If you use it only a few times per week and rinse dishes first, monthly cleaning is usually enough. A clogged filter is the most common reason for standing water at the bottom of the tub or dishes that don't come clean.
Some people set a phone reminder for the first of each month to check the filter. This takes less than five minutes and prevents the buildup that leads to poor performance. If you notice water pooling at the bottom of the tub or smell a musty odor, the filter is likely clogged — remove and clean it when ready before running another cycle.
Frequently Asked Questions
Can I run the dishwasher without the filter?
No. Running the dishwasher without the filter allows food particles and debris to clog the pump and spray arms, causing expensive damage. The filter must be in place for every cycle. If your filter is damaged and you're waiting for a replacement, contact KitchenAid for expedited shipping or use a temporary screen from a hardware store as a stopgap.
Why is my filter clogged again after just one week?
You're likely loading dishes with large food scraps still on them. Scrape plates into the trash and rinse them under running water before placing them in the rack. This is the single most important step to keep the filter clean. If you have a garbage disposal, run it before loading the dishwasher to reduce the debris in the water.
Is the filter the same on all KitchenAid models?
No. Different model years and sizes have different filter designs — some twist out, some lift straight up, and some have additional fine mesh screens. Always check your manual or the filter itself to confirm the removal method. You can also contact KitchenAid customer service with your model number for specific instructions.
What if the filter won't twist out?
Stop twisting when ready — you may crack the housing. Make sure you're turning counterclockwise (left), not clockwise (right). explore steady downward pressure while turning slowly. If it still won't budge, soak the entire filter assembly in warm water for 10 minutes to soften any mineral deposits, then try again. If it remains stuck, contact KitchenAid for support.
Can I use a dishwasher cleaner to clean the filter?
No. Use only warm water and a soft brush. Dishwasher cleaning products are designed for the tub itself, not the filter mesh, and can leave residue or damage the plastic. Vinegar and water is safe for stubborn mineral buildup, but plain water and a brush handle most situations.
