Where the filter is and why it needs cleaning

Samsung washers have a drain filter that catches lint, coins, buttons, and other debris before they reach the drain pump. Over time this filter clogs, which slows drainage and can leave water pooled at the bottom of the drum after a cycle ends. Cleaning it takes about ten minutes and requires no tools.

The filter sits behind a small panel at the bottom front of the machine. On most Samsung models, you'll see a rectangular or circular access door, usually white or stainless steel to match the washer. Some models have the filter on the left side, others on the right—check your manual if you're unsure, but the panel is always at the bottom of the front face.

You should clean this filter every month or two, or sooner if you notice water draining slowly or pooling inside the tub after the wash cycle finishes. Lint buildup is normal and not a sign anything is broken.

Key Takeaways

  • The drain filter is a small cylindrical or flat cartridge behind the bottom front panel of your Samsung washer that traps lint and debris.
  • You can access and clean it yourself by opening the access door, unscrewing the filter by hand, and rinsing it under running water.
  • Cleaning the filter takes about ten minutes and should be done every month or two to keep water draining properly.
  • If water still pools after cleaning the filter, the drain hose or pump may be blocked, and you should check those next before calling a technician.

How to open the access panel

Start with the washer empty and unplugged. Locate the small rectangular or circular panel at the bottom front of the machine. On most Samsung models, this panel either pops off by hand or is held by a single screw.

If it pops off, grip the edges and pull gently toward you—it should release without force. If it's screwed on, use a flathead screwdriver to turn the screw counterclockwise. Once the panel is off, set it aside where you won't step on it. You'll now see the filter cartridge, which looks like a short cylinder or flat disc with a handle or knob on the end.

Have a shallow pan or towel ready before you touch the filter. Even after draining, a small amount of water may spill when you open the filter housing.

Remove and rinse the filter

Grip the filter handle or knob and turn it counterclockwise by hand. It should unscrew without much force—if it's stuck, wrap a cloth around it for grip and try again, but do not force it. Once it's loose, pull it straight out toward you.

Hold the filter under warm running water and rinse both the inside and outside surfaces. Use your fingers or a soft brush to loosen lint and debris. Do not use a wire brush or scrub aggressively, as the filter material can tear. Rinse until the water runs clear and no lint comes away.

While the filter is out, look inside the filter housing (the opening where the filter was). Wipe away any lint or debris you see with a damp cloth or paper towel. This step prevents debris from clogging the pump again right after you reinstall the filter.

Reinstall the filter and close the panel

Insert the clean filter back into the housing, aligning the handle or knob with the opening. Turn it clockwise by hand until it's snug. Do not overtighten—hand-tight is enough. If you turn too hard, you risk cracking the filter or stripping the threads.

Close the access panel. If it pops on, press it firmly until you hear or feel it click into place. If it screws on, insert the screw and turn it clockwise until snug, again without forcing it.

Plug the washer back in and run a short cycle (like a rinse and spin) to confirm water drains normally. If water still pools at the bottom after the cycle, the blockage may be further down the drain line or in the pump itself.

What to do if the filter is cracked or won't drain

If you see cracks in the filter cartridge or if water still drains slowly after cleaning, the filter may need to be replaced. Samsung sells replacement filters for most models—search for your model number plus "drain filter" to find the right part. Replacement filters cost between $15 and $40 and install the same way you just cleaned it.

If the filter is clean and intact but water still pools, the drain hose may be kinked or blocked, or the drain pump itself may be stuck. Check that the drain hose (the rubber tube at the back of the washer that leads to your standpipe or sink) is not bent or pinched. If the hose is clear and water still won't drain, the pump may need professional service.

How often to clean and signs you've waited too long

Clean the filter every month or two as routine maintenance. If you wash heavily soiled loads (work clothes, garden clothes, towels with lots of lint), clean it monthly. For lighter use, every two months is usually enough.

Signs the filter needs cleaning include water draining slowly, water pooling at the bottom of the tub after a cycle, a musty smell from the washer, or error codes related to drainage (like "5E" or "5C" on Samsung models). If you see any of these, clean the filter before running another load.

Waiting too long can cause the pump to work harder and wear out faster, and standing water in the tub can develop mold or mildew. Regular cleaning prevents both problems and keeps your washer running normally.

Frequently Asked Questions

Can I clean the filter while the washer is plugged in?

No. Always unplug the washer before opening the access panel or touching the filter. This is a safety precaution even though the filter itself is not electrical. Unplugging takes five seconds and prevents any risk.

What if I can't unscrew the filter by hand?

Wrap a dry cloth around the filter knob to improve grip and try again. If it still won't budge, let the washer sit for an hour—sometimes mineral deposits or lint can cause it to stick. Do not use pliers or a wrench, as these can crack the filter. If it remains stuck after waiting, contact a Samsung technician rather than force it.

Is it normal for water to spill when I open the filter?

Yes. A small amount of water stays in the filter housing even after a drain cycle. Have a towel or shallow pan ready before you unscrew the filter. This is not a sign anything is wrong.

How do I know which replacement filter to order?

Find your washer's model number (usually on a sticker inside the door frame or on the back of the machine) and search for "[model number] drain filter" on Samsung's parts website or a major appliance parts retailer. The correct filter will be listed for your specific model.
