Can you clean a KitchenAid dishwasher filter? Yes, absolutely! Cleaning your KitchenAid dishwasher filter is a simple, vital task that keeps your dishes sparkling and prevents bad smells. This article will walk you through all the necessary steps to clean KitchenAid dishwasher filter easily. We will cover everything from removing KitchenAid dishwasher filter parts to the best way to clean dishwasher filter assemblies. Regular care prevents many common issues, like poor washing performance or that frustrating musty odor.
Why Filter Cleaning Matters for Your KitchenAid Dishwasher
Your dishwasher filter is the unsung hero of clean dishes. It catches food scraps, grease, and other bits before they clog the wash arms or drain pump. If this filter gets too dirty, water flow slows down. This means less effective spraying and dirty dishes coming out of the machine. Plus, trapped food particles start to rot, leading to that awful smell. Consistent KitchenAid dishwasher filter maintenance keeps your appliance running smoothly for years.
Signs You Need to Clean the Filter
How do you know it’s time for a clean? Watch for these clues:
- Dishes are still gritty or have food stuck to them after a full cycle.
- You notice standing water at the bottom of the dishwasher tub after a cycle ends.
- A noticeable foul odor comes from the dishwasher when you open the door.
- The wash cycle seems much louder than usual.
If you spot any of these issues, grab your gloves! It is likely time for unclogging KitchenAid dishwasher filter components.
Locating and Accessing Your KitchenAid Dishwasher Filter
The first hurdle is finding the filter. Most modern KitchenAid dishwashers use a removable cylinder filter system located at the bottom center of the tub, right under the lower spray arm.
Step 1: Prepare for Filter Removal
Before you start, safety first!
- Turn Off Power: Unplug the dishwasher or switch off the power at the circuit breaker. This is crucial for safety.
- Empty the Dishwasher: Make sure the dishwasher is completely empty. You need clear access to the base.
- Gather Supplies: You will need a soft cloth, a mild dish soap, an old toothbrush, and running water.
Step 2: Removing KitchenAid Dishwasher Filter Components
The system is usually designed for easy removal. It often involves two main parts: a coarse filter screen and a fine filter cylinder.
Accessing the Lower Spray Arm
First, you must move the lower spray arm out of the way.
- Grasp the lower spray arm firmly.
- Twist it counter-clockwise (usually) until it unlocks from its base.
- Lift the spray arm straight up and set it aside somewhere clean. Be careful not to damage the plastic clips.
Taking Out the Coarse Filter
Directly below where the spray arm sat, you will see the main filter assembly.
- Look for the cylindrical filter element. It usually has a handle or a grip area.
- Twist the cylinder part counter-clockwise, often about a quarter turn. You will feel it release from the locking base underneath.
- Lift the cylinder straight out. This is the primary filter unit.
Taking Out the Fine Filter Screen (If Present)
Beneath the main cylinder, there might be a flat, mesh screen called the cleaning KitchenAid dishwasher drain screen.
- Carefully lift this flat screen out of its housing.
- Set all parts (cylinder, coarse screen, fine screen) on a towel near the sink.
If you have an older model, the filter might look slightly different, but the twist-and-lift motion is standard for removing KitchenAid dishwasher filter parts. Check your owner’s manual if you cannot locate the latch mechanism.
Deep Cleaning KitchenAid Dishwasher Filter: The Right Way
Now that the parts are out, it is time for the deep cleaning KitchenAid dishwasher filter session. This process removes stubborn grease and debris.
Step 3: Initial Rinsing
Take all the removed filter parts to your sink.
- Hold the parts under warm running water. Let the water flow through the mesh and openings.
- Gently shake the parts to dislodge loose food particles.
- Rinse until most visible debris washes away.
Step 4: Scrubbing Away Grime
This is where soap and a soft brush come into play.
- Apply a few drops of mild dish soap to a soft sponge or cloth. Do not use harsh chemicals, bleach, or abrasive scouring pads, as these can damage the delicate filter mesh.
- Gently scrub both the inside and outside surfaces of the cylindrical filter. Pay special attention to the screen mesh areas.
- Use an old, soft toothbrush to carefully scrub the crevices and the fine mesh of the cleaning KitchenAid dishwasher drain screen. This is often the key to unclogging KitchenAid dishwasher filter blockages.
Step 5: Addressing Stubborn Smells
If you are fixing smelly KitchenAid dishwasher filter issues, a vinegar soak can help sanitize and deodorize.
- Prepare a bowl of warm water mixed with one cup of white distilled vinegar.
- Submerge the clean filter parts in this solution for about 15 to 30 minutes.
- After soaking, give them a final rinse under clear, running water to wash away any vinegar residue.
Tip: If you notice mineral deposits (white, chalky buildup), soaking in straight vinegar for longer might be necessary before scrubbing.
Step 6: Inspecting the Filter Housing
While the filter parts are soaking, take a moment to look at the area where the filter sits inside the dishwasher tub.
- Wipe down the base plate using a damp cloth.
- Ensure no stray food scraps or broken glass shards remain in the sump area before you put the clean filter back. This preventative step supports good overall KitchenAid dishwasher filter maintenance.
| Cleaning Tool | Recommended Use | Caution |
|---|---|---|
| Mild Dish Soap | General grease and food residue removal. | Never use abrasive cleaners or scouring powders. |
| Soft Sponge/Cloth | Gently wiping the filter surfaces. | Avoid stiff brushes that might tear the mesh. |
| Old Toothbrush | Scrubbing tight corners and fine mesh. | Use only soft bristles. |
| White Vinegar | Sanitizing and dissolving mild mineral deposits. | Rinse thoroughly after soaking. |
Reassembling the Filter System Correctly
Putting everything back together correctly is as important as the cleaning itself. Incorrect assembly can lead to leaks or poor filtration.
Step 7: Reinserting the Fine Screen (If Applicable)
- Place the fine mesh screen (if you have one) back into its flat base slot first. Ensure it sits perfectly flush with the floor of the dishwasher tub.
Step 8: Reinserting the Main Filter Cylinder
- Take the cleaned cylinder filter. Align its base with the housing opening.
- Gently push the cylinder down until it seats firmly.
- Twist the cylinder clockwise until it locks securely into place. You should feel a distinct click or stop. It should not spin freely. If it spins freely, it is not locked, which will cause leaks and poor washing.
Step 9: Replacing the Lower Spray Arm
- Align the lower spray arm over the center post.
- Push it down firmly, then turn it clockwise until it locks.
- Test it by spinning it by hand; it should move freely in a circle without rubbing against anything. Make sure it does not interfere with the filter assembly.
Step 10: Restoring Power and Testing
- Plug the dishwasher back in or flip the circuit breaker switch back on.
- Run a short rinse or quick cycle without any dishes.
- Check immediately under the door seal while water is spraying to ensure no water is leaking from the filter base. If you see leaks, power down and re-check that the filter cylinder is fully locked (Step 8).
Following these KitchenAid dishwasher filter cleaning instructions diligently will maximize performance.
Frequency of Filter Cleaning: How Often is Enough?
How often should you perform this routine maintenance? The answer depends on how heavily you use your dishwasher and what kind of food you wash.
- Light Use (Once or twice a week): Clean the filter every 2 to 3 months.
- Heavy Use (Daily): Check and clean the filter monthly.
- If Dishes Come Out Dirty: Clean it immediately, regardless of the schedule.
Consistent cleaning is the best way to clean dishwasher filter in the long run, as it prevents buildup that requires intense scrubbing later. Aim for proactive maintenance rather than reactive fixing.
Advanced Scenarios: Troubleshooting Common Filter Issues
Sometimes cleaning alone isn’t enough. Here are solutions for deeper problems related to the filter system.
Dealing with Stubborn Clogs and Slow Drains
If you’ve cleaned the filter but the water still drains slowly, the clog might be past the filter, deeper in the drain line or pump.
- Check the Chopper Blade Area: Some KitchenAid models have a small area near the filter sump that contains a chopper blade meant to grind up tough food debris. If this area is blocked (often by a piece of broken glass or a seed), water flow stops. Use needle-nose pliers (with power off!) to carefully probe this area for foreign objects. Do not stick your fingers deep into the sump.
- Inspect Wash Arms: Ensure the tiny holes in the upper and lower spray arms are clear. Mineral deposits or food bits can block these holes, leading to poor spray action even with a clean filter. Use a toothpick to poke through any clogged holes.
When is KitchenAid Dishwasher Filter Replacement Necessary?
Even the best cleaning cannot save a damaged part. You might need a KitchenAid dishwasher filter replacement if:
- The plastic locking tabs on the cylinder are cracked or broken, preventing a secure seal.
- The fine mesh screen is visibly ripped or has holes larger than pinpricks. A torn screen lets large debris into the pump, which is a major repair risk.
- The filter assembly seems warped due to excessive heat or harsh cleaning chemicals used previously.
Replacement parts are usually inexpensive and easy to install—often just involving removing the old unit and snapping the new one into place, similar to the removal steps detailed above. Always verify your model number when ordering a KitchenAid dishwasher filter replacement to ensure compatibility.
Fathoming Filter Operation: Coarse vs. Fine Filtration
KitchenAid often uses a multi-stage filtration system. It is important to know the role of each piece when performing KitchenAid dishwasher filter cleaning instructions:
- Coarse Screen/Cylinder: This traps the largest debris (rice, large seeds, bone fragments). This part gets dirty fastest.
- Fine Filter (Sump Screen): This is a finer mesh that catches smaller particles (grit, grease film). It protects the drain pump.
If you only clean the large cylinder, you miss the fine filter, which is a common reason for lingering grime and odors.
Maintaining a Fresh-Smelling KitchenAid Dishwasher
Odors usually happen when decaying food sits in the filter or sump for days between uses. Regular cleaning prevents this, but sometimes extra deodorizing is needed.
- The Baking Soda Boost: After a deep clean, place half a cup of baking soda on the bottom rack. Run a short, hot water cycle (without detergent). Baking soda is excellent at absorbing residual smells.
- Lemon Power: Running a cycle with slices of lemon or a cup of lemon juice (added to the detergent dispenser) can leave a fresh, clean scent. This is a great addition after fixing smelly KitchenAid dishwasher filter problems.
This proactive approach to KitchenAid dishwasher filter maintenance is far easier than dealing with a seriously blocked or smelly machine later on.

Frequently Asked Questions (FAQ)
Q1: Can I run my KitchenAid dishwasher without the filter installed?
A: No, you must never run your dishwasher without the filter installed, even for a short test cycle. The filter protects the drain pump and circulating pump from food debris. Running the dishwasher without it will almost certainly cause clogs, damage the pump, and require costly repairs.
Q2: What kind of soap is safe for cleaning the KitchenAid dishwasher filter?
A: Only use mild dish soap, like the kind you use for hand-washing dishes. Avoid strong detergents, bleach, or abrasive cleaners. Harsh chemicals can degrade the plastic housing or damage the fine mesh material of the filter.
Q3: My filter looks clean, but my dishes are gritty. What should I check next?
A: If the filter is clean, the next step in unclogging KitchenAid dishwasher filter related issues is checking the spray arms. Food particles often get lodged in the tiny holes of the spray arms, preventing proper water distribution. Use a toothpick or thin wire to clear every hole in both the upper and lower arms.
Q4: How often should I look at the fine drain screen?
A: If your model has a separate fine drain screen, you should inspect it every time you clean the main cylindrical filter. This component traps the smallest particles that cause odors and long-term drainage issues.
Q5: Is it hard to find a KitchenAid dishwasher filter replacement?
A: No. KitchenAid dishwasher filter replacement parts are generally easy to find online through appliance parts retailers or directly from KitchenAid. You will need your dishwasher’s model number, usually found on a sticker inside the door frame, to ensure you order the correct part kit.
