Yes, KitchenAid dishwashers have filters you need to maintain

Every KitchenAid dishwasher has a filter system that traps food particles and debris during the wash cycle. Unlike older dishwashers that used disposable filters, KitchenAid models use a permanent filter assembly that you clean by hand after each load or every few days, depending on how much you use the machine. The filter sits at the bottom of the tub and catches particles before they can recirculate onto your dishes or clog the drain.

The filter is not optional—it is a working part of the machine. If you do not clean it regularly, water will drain slowly, dishes will come out dirty, and you may see standing water at the bottom of the tub. Most KitchenAid owners find that a quick rinse under running water takes less than a minute and prevents problems before they start.

Key Takeaways

  • KitchenAid dishwashers have a permanent filter assembly at the bottom of the tub that you remove and rinse by hand.
  • You should clean the filter after every load or at least once a week to prevent slow drainage and poor wash results.
  • The filter comes apart into two pieces—an upper fine-mesh filter and a lower coarse filter—and both rinse clean under running water.
  • If water drains slowly or dishes come out spotted, a clogged filter is usually the first thing to check.
  • Replacement filters are available from KitchenAid if the mesh becomes damaged, though the filter itself rarely needs replacing with normal use.

Where the filter is located and what it looks like

The filter assembly sits in a cylindrical housing at the bottom center of the dishwasher tub, directly below the spray arm. To find it, open the door, look down at the floor of the tub, and you will see a round or oval cage-like structure. On most KitchenAid models, the filter twists counterclockwise to release—you do not need tools, just your hands.

Once you pull it out, you will see it is made of two parts. The upper piece is a fine-mesh filter that catches smaller particles. The lower piece is a coarser filter basket that holds larger debris. Both pieces work together to keep the drain clear. The whole assembly is usually made of plastic with stainless steel or plastic mesh screens.

How to clean the filter after each load

After the cycle ends, let the dishwasher cool for a few minutes, then open the door and twist the filter counterclockwise until it releases. Lift it straight up and out of the housing. Hold it under warm running water and rinse both the upper and lower sections. Use your fingers or a soft brush to gently rub away any stuck-on food or film. Do not use a dishwasher or put it in the sink with other dishes—hand-rinsing takes 30 seconds and keeps the mesh from getting damaged.

Once it is clean, twist it back into the housing clockwise until it sits flush with the tub floor. You will feel it click or seat firmly when it is in the right position. If water still pools at the bottom after cleaning, check that the filter is fully seated and that nothing is blocking the drain opening below it.

When the filter needs deeper cleaning

If rinsing under water does not remove all the buildup—especially if you notice a smell or see a film on the mesh—soak the filter in warm water with a little white vinegar for 15 to 20 minutes, then scrub gently with a soft brush. This removes mineral deposits and grease that plain water sometimes misses. Rinse thoroughly and let it air-dry before reinstalling.

Some KitchenAid owners also remove the lower spray arm (it usually twists out) and rinse the holes to make sure they are not clogged. A clogged spray arm combined with a dirty filter is the most common reason dishes come out poorly washed. Both take just a minute to check.

Signs your filter needs attention right away

Water pooling at the bottom of the tub after a cycle is the clearest sign the filter is clogged. Dishes coming out with spots, film, or food residue also points to a dirty filter—the water cannot circulate properly if the filter is blocked. You might also notice the dishwasher running longer than usual or hear the drain pump working harder than normal.

If you clean the filter and the problem persists, check the drain hose under the sink to make sure it is not kinked or clogged. A blocked drain line can cause the same symptoms as a dirty filter, and both should be checked before you assume the dishwasher itself has a problem.

Replacing the filter if it becomes damaged

The filter mesh can tear or wear out if it is scrubbed too hard or if something sharp gets caught in it. KitchenAid sells replacement filter assemblies for most models, and they cost between $30 and $60 depending on the model. You can find the part number in your user manual or by searching your model number on the KitchenAid website.

Installation is the same as cleaning—twist out the old filter, twist in the new one, and make sure it seats fully. You do not need a technician for this. However, with normal hand-rinsing and care, the original filter usually lasts the life of the dishwasher. Replacement is rare unless the mesh is visibly torn or the plastic housing cracks.

How often you should clean the filter

The safest routine is to rinse the filter after every load, especially if you rinse dishes before loading them (which most people do). This takes 20 to 30 seconds and prevents any buildup. If you run the dishwasher only once or twice a week, you can clean the filter every few days instead of after each load, but do not go longer than a week without checking it.

Heavy use—such as running the dishwasher daily with large pots, pans, and plates—means you should clean the filter more often. If you notice water draining slowly or dishes not coming clean, move to cleaning after every load until the problem clears. Once you get into the habit, it becomes automatic and takes almost no time.

Frequently Asked Questions

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

No. The mesh can tear in the wash cycle, and the filter needs to be rinsed by hand under running water. It takes less than a minute and keeps the filter in good condition for years.

What if my KitchenAid filter is stuck and will not twist out?

Let the dishwasher cool completely, then try again with a dry cloth for grip. If it is still stuck, soak the area around the filter housing with warm water for a few minutes to loosen any mineral deposits. Twist gently—do not force it, as the plastic can crack.

Do I need to replace the filter if it looks discolored?

Discoloration from minerals or staining does not mean the filter is broken. If water still drains and dishes come clean after you rinse it, the filter is working fine. Soak it in vinegar if the appearance bothers you, but replacement is only needed if the mesh tears or the plastic cracks.

Why does my dishwasher smell bad even after I clean the filter?

A smell usually means bacteria or mold is growing in the drain line or spray arm, not just the filter. Clean the filter, then run an empty cycle with a cup of white vinegar on the bottom rack to freshen the whole machine. If the smell returns, the drain hose under the sink may need cleaning.

Is the filter the same on all KitchenAid models?

Most KitchenAid dishwashers use a similar two-part filter system, but the exact shape and part number vary by model. Check your user manual or the KitchenAid website with your model number to confirm the filter type and find replacement parts if needed.
