Where the filter is and why it matters
Your Samsung dishwasher has a removable filter at the bottom of the tub that traps food particles and debris. Over time, this filter clogs and reduces water flow, which means dishes come out dirty and the machine has to work harder. Cleaning it takes about five minutes and should happen once a month, or more often if you rinse dishes heavily or run the machine daily.
The filter sits in a cylindrical cage at the lowest point inside the tub. You'll see it when you open the door and look down — it's usually made of plastic mesh and looks like a small cup or basket. Samsung makes several models, and the exact shape varies, but the removal and cleaning process is nearly identical across all of them.
Key Takeaways
- The filter is located at the bottom center of the dishwasher tub and should be cleaned monthly to keep water flowing freely.
- Most Samsung filters twist counterclockwise to unlock and lift straight out — no tools needed.
- Rinse the filter under hot running water and use a soft brush or old toothbrush to scrub away trapped food and grease.
- If the filter is cracked, discolored, or no longer fits snugly after cleaning, it may need to be replaced with a genuine Samsung part.
Step-by-step removal and cleaning
Start with an empty dishwasher. Open the door and look at the bottom of the tub. You'll see a cylindrical cage with a filter inside. Grasp the top of the filter cage with one hand and twist it counterclockwise — usually a quarter turn is enough to unlock it. Once unlocked, pull straight up and out. The cage and filter come out as one unit on most models.
Separate the two pieces. The outer cage usually twists or slides off the inner filter. Hold the filter under hot running water and rinse away loose food and debris. Use a soft brush — an old toothbrush works well — to gently scrub the mesh surface and remove stubborn buildup, especially grease. Pay attention to the underside and the edges where particles collect. Rinse again until the water runs clear.
While the filter is out, take a moment to rinse the cage and the filter well in the tub. Use your brush to clean the opening where the filter sits, since debris can accumulate there too. Once everything is clean and dry, reassemble the cage and filter, then twist it clockwise back into the tub until it sits flush and snug. You should feel a slight resistance when it locks into place.
What to do if the filter is stuck or won't come out
If the filter won't twist, it may be caked with mineral deposits or grease. Fill a bowl with equal parts white vinegar and hot water, submerge the filter cage, and let it soak for 30 minutes. The vinegar softens mineral buildup and makes the plastic easier to grip. After soaking, try twisting again with a dry cloth for better grip.
If it still won't budge, do not force it — you risk cracking the plastic. Instead, run the dishwasher empty on a hot cycle with a cup of white vinegar in the bottom. This heats and loosens the deposits throughout the machine. After the cycle finishes and the tub cools, try removing the filter again. If you still cannot remove it after two attempts, the cage may be damaged and you may need to contact Samsung support or a repair technician.
Signs the filter needs to be replaced
A filter that has been cleaned regularly can last several years, but damage or wear means replacement. Look for cracks in the mesh, permanent discoloration that doesn't rinse away, or a warped shape that no longer fits snugly in the cage. If the mesh has holes or tears, water bypasses the filter and debris reaches the pump, which can cause bigger problems down the line.
You can order a genuine Samsung replacement filter through the Samsung website, Amazon, or appliance parts retailers. The part number varies by model — check your dishwasher's manual or the Samsung support page for your specific model number. Replacement filters typically cost between $20 and $40 and take five minutes to install using the same twist-and-lift method.
How often to clean and what affects the schedule
Monthly cleaning is the standard recommendation, but your situation may call for more frequent attention. If you run the dishwasher daily, have a large household, or rarely rinse dishes before loading, clean the filter every two weeks. If you live alone and run the machine once or twice a week with rinsed dishes, monthly is sufficient.
Hard water and high mineral content also speed up buildup. If you have hard water, you may notice mineral deposits on the filter even after light use. In that case, add a rinse aid to your dishwasher — it reduces mineral spotting and buildup on all interior surfaces, including the filter. Check the rinse aid dispenser on the inside of the door and refill it when the indicator shows empty.
Troubleshooting poor cleaning results after filter maintenance
If dishes still come out dirty after you've cleaned the filter, the problem may be elsewhere. Check the spray arms — the rotating parts that spray water during the cycle. Food particles can block the small holes in the arms, reducing water pressure. Remove the spray arms (they usually pull straight out or twist off) and rinse them under hot water, using a toothpick or small brush to clear any blocked holes.
Also inspect the drain at the bottom of the tub, separate from the filter cage. Debris can collect there and prevent water from draining, which affects the next cycle. If water pools at the bottom after a cycle finishes, the drain may be clogged. Run a cycle with vinegar as described above, or contact Samsung support if the drain remains blocked after cleaning.
Frequently Asked Questions
Can I run the dishwasher without the filter?
No. The filter protects the pump from large food particles and debris. Running the machine without it can damage the pump, which is expensive to repair. Always reinstall the filter before running a cycle, even if you're just rinsing it out.
What's the difference between the filter and the drain?
The filter traps food particles during the wash cycle. The drain is a separate opening at the bottom that lets water exit the tub after washing. Both need to stay clear, but they serve different purposes. If your dishwasher isn't draining, the problem is usually the drain, not the filter.
Is it safe to put the filter in the dishwasher to clean it?
Yes, you can place the filter in the top rack of the dishwasher during a hot cycle to clean it, but hand-rinsing under hot water is faster and just as effective. If you do run it through the dishwasher, remove it before the drying cycle, since high heat can warp plastic filters over time.
How do I know what model Samsung dishwasher I have?
The model number is printed on a label inside the door frame, usually on the left side near the hinge. It starts with letters like DW or DWF followed by numbers. Write this down and keep it handy — you'll need it if you ever order replacement parts or contact support.
What should I do if the filter cage is cracked?
A cracked cage allows debris to bypass the filter and reach the pump. You'll need to replace the entire cage assembly, not just the filter. Order the correct part for your model number and follow the same removal and installation steps. If you're unsure which part to order, contact Samsung support with your model number.
