Reset the filter light by holding the dedicated button for three seconds
The water filter light on a Samsung refrigerator resets with a single button press — usually the Ice/Water button or a dedicated Filter button, held for three seconds until the light goes dark. The exact button depends on your model, but Samsung places it either on the front panel below the dispenser or inside the fridge near the filter housing. You do not need to remove the filter or turn off the refrigerator.
The light comes on after the filter has been in use for six months or 300 gallons of water, whichever comes first. Resetting it tells the refrigerator to start counting down to the next replacement. If you replace the filter and forget to reset the light, the refrigerator will keep warning you even though the filter is new — resetting clears that false alarm.
The reset takes about five seconds total. If the light does not go off after holding the button, you may be pressing the wrong button, or your model may use a different reset method. Check your model number to confirm which button controls the filter light.
Key Takeaways
- Hold the Ice/Water or Filter button for three seconds to reset the light — do not press and release quickly.
- The light resets after you install a new filter so the refrigerator can track the next six-month cycle.
- If the light stays on after holding the button, check your model number in the manual to find the correct reset button.
- You do not need to turn off the refrigerator or remove anything to reset the light.
- The filter light is a reminder only — it does not stop the refrigerator from dispensing water if you ignore it.
Locate the filter light and reset button on your model
Samsung refrigerators have the filter light in one of two places: on the front panel near the water and ice dispenser, or inside the fridge on the door or wall near the filter cartridge. The light is usually small and round, colored blue or white when the filter is good and amber or red when it needs replacement.
The reset button is almost always the same button you use to dispense water or ice. On most models, this is labeled Ice/Water and sits on the front panel below the dispenser. On some newer models, Samsung added a separate Filter button nearby. If you have a built-in refrigerator or a model with the filter inside the fridge, the reset button may be on the interior wall or door frame instead.
If you cannot find the button or light, look up your model number — it is printed on a sticker inside the fridge, usually on the top wall or back wall. Search "[Your Model Number] filter reset" to see a photo of where the button is on your specific refrigerator.
Hold the button for the full three seconds
The most common mistake is pressing the button too quickly. A short tap will dispense water or ice, but it will not reset the filter light. You must hold the button down continuously for three full seconds. Count slowly: one-one-thousand, two-one-thousand, three-one-thousand. Keep your finger on the button the entire time.
You will usually hear a beep or see the light blink when the reset is complete. Some models show no visible change — the light straightforward stays off. If nothing happens after three seconds, release the button and try again, making sure you are holding it the full duration.
If you hold the button too long (five or more seconds), some models will start dispensing water. This is harmless — just release the button and try the three-second hold again.
Reset the light after you install a new filter
The filter light is meant to reset after you replace the cartridge. Samsung filters are designed to last about six months under normal use, and the light counts down from that point. When you install a new filter, the light should go off on its own — but if it stays on, you need to manually reset it.
Turn off the water supply to the refrigerator before you remove the old filter. Locate the filter housing (usually under the sink, in the basement, or inside the fridge), turn the cartridge counterclockwise to unscrew it, and pull it straight out. Insert the new filter by pushing it in and turning it clockwise until it stops. Do not force it — it should turn smoothly.
Once the new filter is installed, hold the reset button for three seconds. The light should go dark. If it does not, try holding the button again, or check that you are pressing the correct button for your model.
What to do if the light will not reset
If the light stays on after you hold the button for three seconds, first confirm you are holding the correct button. Press the Ice/Water button and watch what happens — if water or ice comes out, you are on the right button. If nothing happens, try the Filter button if your model has one, or look for a button on the interior of the fridge.
Second, make sure you are holding the button long enough. Set a timer on your phone and hold for exactly three seconds. Some models require a slightly longer hold — try five seconds if three does not work.
If the light still will not reset, the light sensor may be faulty or the filter cartridge may not be seated correctly. Remove the filter, check that the housing is clean and dry, and reinstall the filter, making sure it clicks or stops turning when fully inserted. Then try the reset again.
If the light remains on after all of this, contact Samsung support with your model number. A faulty sensor is rare but possible, and Samsung can walk you through a factory reset or arrange a service call if needed.
Understand what the filter light actually means
The filter light is a maintenance reminder, not a safety shutoff. If you ignore it and do not replace the filter, the refrigerator will continue to dispense water and ice normally. The light straightforward tells you that the filter has been in use for six months or has filtered about 300 gallons of water.
How quickly the filter fills depends on how much water you use. A household that fills a pitcher every day will reach 300 gallons in about ten months. A household that uses the dispenser rarely might take a year or more. The six-month timer is an estimate based on average use.
If you reset the light without replacing the filter, you are telling the refrigerator to start a new six-month countdown. The water quality will not change, but you are resetting the reminder. It is best practice to replace the filter when the light comes on, but the refrigerator will not force you to do so.
Frequently Asked Questions
Do I have to reset the light myself, or does it reset automatically?
Most Samsung models reset the light automatically when you install a new filter — the sensor detects the fresh cartridge and turns the light off. If the light stays on after you install a new filter, you must manually reset it by holding the button. Some older models always require a manual reset.
What if I press the reset button and water starts dispensing?
You are holding the button too long. Release it when ready and try again with a three-second hold. The water dispensing is harmless — just place a cup under the dispenser or let it run into the sink. The button controls both water dispensing and filter reset, so timing matters.
Can I reset the light without replacing the filter?
Yes, you can reset the light without replacing the filter. The light is only a reminder — it does not stop the refrigerator from working. However, Samsung recommends replacing the filter every six months for best water quality, so resetting without replacing means you will lose track of when the filter actually needs changing.
Where is the filter light on a Samsung French door refrigerator?
On French door models, the filter light is usually on the front panel below the water and ice dispenser, or inside the fridge on the upper right wall near the filter cartridge. Check your model number in the manual if you cannot locate it — the position varies by year and series.
How do I know which button is the filter reset button if my refrigerator has multiple buttons?
The filter reset button is almost always the Ice/Water button you use to dispense beverages. If your model has a separate Filter button, try that one. If neither works, search your model number online to see a diagram, or call Samsung support with the model number and they can tell you exactly which button to use.
