Turn off the water supply before you remove the old filter
The first step is to locate your Samsung refrigerator's water shut-off valve, usually found behind the unit or under the sink if your fridge is connected to a water line. Turn the valve clockwise until it stops — you do not need to force it. This prevents water from spraying out when you remove the filter cartridge.
If you cannot find a shut-off valve or it will not turn, you can still change the filter, but water will leak into the drip tray beneath it. Have towels ready and be prepared to empty the tray several times during the process.
Locate and access your filter cartridge
Samsung refrigerators have filters in different locations depending on the model. Most commonly, the filter sits inside the fridge in the upper right corner, behind a small panel or grille. Some models place it in the base grille at the bottom front of the refrigerator. A few older models have filters in the back, accessible from outside.
Check your refrigerator's manual or look for a small button or latch near where you think the filter is. Press or turn it to release the panel. If you cannot locate your filter, search online for your specific model number — it is printed on a sticker inside the fridge, usually on the side wall or ceiling.
Remove the old filter by turning it counterclockwise
Once you can see the filter, grip it firmly and turn it counterclockwise (to the left). Most Samsung filters are designed to twist out like a light bulb. Turn slowly — you may feel resistance as the seal breaks. Continue turning until the filter comes free from its housing.
Water will drip from the filter and the opening where it was seated. Hold the old filter over a towel or bucket to catch the water. Do not panic if water continues to drip for a few seconds after removal — this is normal.
Key Takeaways
- Shut off the water supply valve behind or under your refrigerator before removing the old filter to prevent water from spraying.
- Samsung filters are located in different spots depending on your model — check your manual or search your model number online to find yours.
- Turn the old filter counterclockwise (to the left) like a light bulb until it twists free from its housing.
- Install the new filter by twisting it clockwise into the same opening until you feel it seat firmly, then run water through the dispenser for 30 seconds to flush the line.
- Replace your filter every six months or when the filter indicator light on your refrigerator turns red, whichever comes first.
Install the new filter by twisting it clockwise into place
Take your new Samsung filter out of its packaging. Some filters come with a protective cap on the inlet — remove this before installation. Align the filter with the opening where the old one came out and push it in gently until you feel it start to catch.
Turn the new filter clockwise (to the right) until it stops. You should feel it seat firmly, but do not over-tighten it. A quarter-turn past snug is usually correct. If the filter will not turn all the way, you may have it slightly misaligned — pull it out a little and try again.
Flush the water line and turn the supply back on
Turn the water shut-off valve counterclockwise to restore water flow. Wait a few seconds for water to reach the filter. Then hold a cup under your refrigerator's water dispenser and run water for 30 seconds without stopping. This flushes air and loose carbon particles from the new filter.
The water may look slightly cloudy or dark during this flush — this is normal and will clear after a few more cups. After flushing, check under the refrigerator and around the filter housing for leaks. If you see water dripping, turn off the supply valve and check that the filter is twisted all the way in.
Reset the filter indicator light on your refrigerator
Most Samsung refrigerators have a filter indicator light on the control panel or inside the fridge. Once you have installed the new filter and flushed the line, this light should be reset so it tracks when your next filter change is due. The reset method varies by model.
Common methods include holding a button labeled "Filter" or "Reset" for three to five seconds, or pressing a combination of buttons on the display panel. Check your manual for the exact steps for your model. If you cannot find the manual, search your model number plus "reset filter light" online — most manufacturers post this information.
Frequently Asked Questions
What happens if I do not turn off the water supply?
Water will spray or drip from the filter opening when you remove the old cartridge. It is not dangerous, but you will need towels and a bucket to catch the water. If you have a shut-off valve, using it takes 30 seconds and prevents the mess.
How do I know which replacement filter to buy?
Your model number is the key. Find it on a sticker inside your refrigerator, usually on the side wall or ceiling. Search that number plus "water filter" online, or call Samsung customer service with the model number and they will tell you the correct part number to order.
Can I use a non-Samsung filter in my Samsung refrigerator?
Third-party filters exist and are often cheaper, but Samsung refrigerators are designed for Samsung filters. Using a different brand may affect water pressure, taste, or fit. Check your warranty — some Samsung warranties do not cover damage caused by non-Samsung parts.
Why is my water still cloudy after I flushed the new filter?
Run water for another 30 to 60 seconds. New filters release fine carbon particles that take a few cups to clear completely. If the water is still cloudy after two minutes of running, turn off the supply and check that the filter is twisted all the way in — a loose filter will not work properly.
How often should I change the filter?
Samsung recommends every six months for most models, though this depends on your water quality and how much water you use. Your refrigerator's filter indicator light will turn red when a change is due. Do not wait for the light — change the filter at six months even if the light has not come on yet.
