The filter is at the bottom of the tub, under the spray arm

Your Samsung dishwasher has a removable filter assembly sitting on the floor of the tub, directly beneath the lower spray arm. It looks like a cylindrical cage with a fine mesh screen wrapped around it. On most Samsung models, you'll see it when ready when you open the door and look down — it's usually white or gray plastic, about 4 to 5 inches tall.

The filter traps food particles and debris so they don't recirculate onto your dishes or clog the spray arm holes. Over time, it collects bits of food, so cleaning it regularly keeps your dishwasher running properly and prevents odors.

Key Takeaways

  • The filter sits at the bottom center of the tub under the lower spray arm and lifts straight out by hand.
  • Most Samsung filters have two parts: an outer cage and an inner fine-mesh filter that twist apart for cleaning.
  • Rinse the filter under running water and use a soft brush to remove trapped food — do not use a dishwasher or scrub with a hard brush.
  • Clean the filter every two to four weeks, or more often if you rinse dishes heavily before loading.

How to remove the filter in three steps

Open the dishwasher door fully and look at the bottom of the tub. You'll see the cylindrical filter assembly sitting in the center, usually held in place by its own weight and a small notch or tab that keeps it from spinning.

Grasp the filter cage with your hand and twist it counterclockwise about a quarter turn. It should loosen when ready. Once it's loose, lift it straight up and out of the tub. Some models have a small handle or knob on top — if yours does, grip that instead of the cage itself.

Set the filter on a clean surface. You now have access to the filter well at the bottom of the tub, which you should also rinse out before putting the filter back.

Taking apart the filter to clean both pieces

Most Samsung dishwashers have a two-part filter: an outer cylindrical cage and an inner fine-mesh screen. To separate them, hold the outer cage in one hand and twist the inner filter counterclockwise. It will come free after a half turn or so.

Rinse both pieces under warm running water. Use your fingers or a soft brush — like an old toothbrush — to gently remove trapped food particles. Pay special attention to the fine mesh screen, which clogs easily. Do not use a hard-bristled brush or scrub aggressively, as you can tear the mesh.

If food is stuck on and won't rinse away, soak both pieces in warm water for 10 to 15 minutes, then rinse again. Never put the filter in the dishwasher itself or use hot water above 140°F, as high heat can warp the plastic.

Cleaning the filter well and spray arm

While the filter is out, take a moment to rinse the well — the recessed area where the filter sits. Food particles and grease can collect there too. Use a damp cloth or soft brush to wipe it clean, then rinse with water.

Check the lower spray arm for clogs. It's the rotating arm above the filter well. Look for small holes around its underside — these can get blocked by food or mineral buildup. If you see debris, use a toothpick or straightened paperclip to gently clear each hole. Do not force it or enlarge the holes.

Putting the filter back and when to replace it

Once both filter pieces are clean and dry, twist the inner fine-mesh filter back into the outer cage clockwise until it's snug. Then place the assembled filter back into the well at the bottom of the tub. Twist it clockwise until it stops — you should feel a slight resistance when it seats properly.

Most Samsung filters last two to three years with regular cleaning. If the mesh tears, cracks, or no longer rinses clean, it's time to replace it. You can order a replacement filter from Samsung's parts website or through a major appliance retailer — filters typically cost between $20 and $50 depending on your model number.

How often to clean and common mistakes to avoid

Clean the filter every two to four weeks if you use your dishwasher regularly. If you have a large household or rinse dishes heavily before loading, clean it every two weeks. If you live alone or use the dishwasher once a week, monthly cleaning is usually enough.

The most common mistake is scrubbing the fine mesh with a hard brush or scouring pad, which tears it. Another is leaving the filter in the dishwasher during a cycle — it can come loose and block the spray arm. Never soak the filter in bleach or run it through the dishwasher itself. If you notice water pooling at the bottom of the tub or dishes coming out dirty, the filter may be clogged — remove and rinse it right away.

Finding your model number if you need a replacement

Your Samsung model number is printed on a sticker inside the door edge or on the back wall of the tub. It usually starts with "DW" or "WD" and looks like "DW80R5061US" or similar. Write it down before you order a replacement filter, because filters vary by model and using the wrong one can cause leaks or poor cleaning.

You can also find the model number on your original paperwork or by searching your email for the receipt or warranty information. Once you have it, search Samsung's official parts site or call their customer service line — the number is on your warranty card or in the owner's manual.

Frequently Asked Questions

Can I run the dishwasher without the filter?

No. Without the filter, food particles will recirculate onto your dishes and clog the spray arm holes, leaving dishes dirty. The filter is essential to how the dishwasher works. Always replace it before running a cycle.

What if the filter won't twist out?

Make sure you're twisting counterclockwise, not clockwise. If it still won't budge, the filter may be stuck due to mineral buildup or food debris. Spray it with white vinegar and let it sit for 15 minutes, then try again. If it's still stuck, do not force it — contact Samsung support for guidance.

Is it normal for the filter to smell bad?

Yes, a musty or sour smell usually means food has been sitting in the filter too long. Clean it thoroughly and rinse the filter well. If the smell returns quickly after cleaning, you may be overloading the dishwasher or not rinsing dishes enough before loading. Cleaning the filter more often will help.

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

Discoloration alone doesn't mean the filter is broken. If it still rinses clean and the mesh isn't torn, it's fine to keep using it. Replace it only if the mesh tears, cracks, or no longer rinses clean even after soaking.

Where can I buy a replacement filter?

Samsung replacement filters are sold through Samsung's official parts website, Amazon, Best Buy, and major appliance retailers. You can also order through local appliance repair shops. Always confirm your model number before ordering to make sure you get the right filter.
