Reset the filter light by pressing and holding the filter button for three seconds
The filter light on a Samsung refrigerator tells you when the water filter needs replacing. Once you install a new filter, the light does not turn off by itself — you have to reset it manually. The reset process takes less than a minute and requires no tools.
The filter button location depends on your model. On most Samsung refrigerators, it is on the front control panel, usually labeled "Filter" or showing a water droplet icon. Some models have the button inside the refrigerator, on the upper right wall or near the ice maker. Check your model number on the back wall of the fridge or inside the door frame if you cannot find it on the front panel.
Press and hold the filter button for three seconds until the light turns off or changes color. The light may blink during the reset, then go dark or return to blue. Release the button once the change happens. The reset is complete, and your new filter is now registered in the system.
Key Takeaways
- The filter button is usually on the front control panel but may be inside the refrigerator on some models.
- Hold the filter button for three seconds to reset the light after installing a new filter.
- The light will turn off or change color when the reset is successful.
- You must reset the light manually each time you replace the filter; it does not reset on its own.
- If the light does not respond after holding the button, try unplugging the refrigerator for five minutes and plugging it back in.
Where to find the filter button on common Samsung models
Samsung refrigerators come in several layouts, and the filter button placement varies. On French-door and side-by-side models, the button is usually on the front control panel between the ice and water dispensers or above them. Look for a small rectangular button or a touch-sensitive area labeled with a water droplet or the word "Filter."
On some bottom-freezer models, the filter button is on the interior wall of the refrigerator section, typically on the upper right side near the ice maker or water line. You may need to open the fridge door and look at the back wall to locate it. A few older Samsung models have the button on the side of the refrigerator near the water and ice dispensers.
If you cannot find the button after checking the front panel and interior walls, consult your model's manual. You can find the manual by searching your model number on Samsung's website or by checking the documentation that came with your refrigerator. The manual will include a diagram showing the exact location for your specific model.
What happens if the filter light does not reset
If you hold the button for three seconds and the light stays on or does not change, the reset may not have registered. Try holding the button for five to ten seconds instead of three. Some models require a longer hold time, and the light may not respond when ready.
If a longer hold does not work, unplug the refrigerator from the wall outlet for five minutes, then plug it back in. This resets the refrigerator's control board and often clears a stuck filter light. Wait for the refrigerator to power back on fully before attempting the reset again.
If the light still does not turn off after unplugging and resetting, the control board may have a fault, or the filter sensor may not be reading the new filter correctly. At this point, contact Samsung support or a refrigerator repair technician. The light will not affect the refrigerator's operation, but a technician can determine whether the sensor needs replacement.
How to know when your filter actually needs replacing
The filter light is a reminder based on time or water usage, not a direct measure of filter condition. Samsung filters are typically rated for six months of use or 300 gallons of water, whichever comes first. If you use less water, your filter may last longer than six months even if the light comes on.
You can also check filter condition by looking at the water quality. If water from the dispenser tastes off, smells like chlorine, or comes out slowly, the filter is likely clogged and should be replaced regardless of whether the light is on. A clogged filter reduces water pressure and may affect ice maker performance.
Keep track of when you installed your current filter. If it has been less than three months and the light came on, the filter may be fine to use longer. If it has been six months or more, replace it even if the light has not come on yet. Replacing on schedule prevents water quality issues and keeps the ice maker working properly.
Steps to replace the filter before resetting the light
Before you reset the light, you need to install the new filter. Most Samsung refrigerators use a cartridge filter that twists in and out. Locate the filter housing, which is usually in the upper right corner of the refrigerator interior or under the sink if your model has an external filter.
Turn the old filter counterclockwise by hand until it comes free. Some filters are tight, so grip firmly and turn slowly to avoid spilling water. Once the old filter is out, water may drip from the housing, so have a towel ready. Wipe the housing opening with a clean cloth to remove any debris.
Insert the new filter into the housing and turn it clockwise by hand until it stops. Do not over-tighten; stop when you feel resistance. Run water through the dispenser for 30 seconds to flush the new filter and remove air from the line. The water may look cloudy at first — this is normal and will clear after a few seconds of running.
Resetting the light on ice maker and water dispenser models
If your Samsung has both an ice maker and water dispenser, the filter light controls the main water filter that serves both systems. Resetting the light tells the refrigerator that a new filter is in place and the water is clean again. The reset applies to both the ice and water functions at the same time.
After you reset the filter light, run water and make ice for a few minutes to may support both systems are working. If the ice comes out cloudy or the water tastes off after resetting, the new filter may not be seated correctly. Remove the filter, check that the housing is clean, and reinstall it, making sure it turns all the way until it stops.
Frequently Asked Questions
Can I reset the filter light without replacing the filter?
Yes, you can press the button and reset the light without installing a new filter. However, this defeats the purpose of the light, which is to remind you when water quality may decline. If you reset the light without replacing the filter, you lose track of when the filter actually needs changing.
How long does the filter light stay off after I reset it?
The light will stay off for approximately six months or until the refrigerator estimates that 300 gallons of water have passed through the filter, whichever comes first. The exact timing depends on how much water and ice you use. Heavy use will trigger the light sooner than light use.
What if I press the button and nothing happens?
Make sure you are pressing the correct button and holding it for at least three seconds. If the button does not respond at all, the control panel may have a fault. Try unplugging the refrigerator for five minutes and plugging it back in to reset the system. If the button still does not work, contact Samsung support.
Does the filter light reset automatically when I install a new filter?
No. The light does not turn off on its own when you replace the filter. You must manually press and hold the filter button for three seconds after installation. This is by design so that the refrigerator knows you have replaced the filter and can start counting down to the next replacement.
Is there a difference in resetting between ice maker filters and water dispenser filters?
Most Samsung models have one main filter that serves both the ice maker and water dispenser, so the reset process is the same. Some models have separate filters, but they are reset using the same button-hold method. Check your manual if you are unsure whether your model has one filter or two.
