Reset the filter light by holding the button for three seconds

The water filter light on a Samsung fridge resets by pressing and holding a button on the control panel or inside the fridge door, depending on your model. Most Samsung refrigerators have a dedicated filter reset button that you hold for three seconds until the light goes off or the display shows a confirmation message. The button is usually labeled "Filter Reset," "Ice/Water," or has a water droplet symbol.

The exact location and method vary by model year and fridge type. Some Samsungs have the button on the front control panel above or below the ice and water dispenser. Others have it inside the fridge, on the wall near the water line or on the ice maker itself. Check your model number on the back wall of the fridge or inside the door frame, then look up the specific reset steps for that number on Samsung's support website.

Key Takeaways

  • Most Samsung filter lights reset by holding a button labeled "Filter Reset" or with a water droplet icon for three seconds.
  • The button location differs by model — check your fridge's manual or Samsung's website using your model number to find yours.
  • The light should turn off or display a confirmation message when the reset is complete.
  • Reset the filter light only after you have physically replaced the water filter cartridge, not before.
  • If the light does not turn off after holding the button, try unplugging the fridge for five minutes, then plugging it back in.

Locate the filter reset button on your specific model

Samsung makes several fridge styles, and the reset button is not always in the same place. On French door and side-by-side models, the button is usually on the front control panel, either above the water dispenser or on the upper right corner of the door. On bottom freezer models, it is often inside the fridge, on the right wall near the water inlet line. On top freezer models, the button may be on the ice maker itself or on the interior wall.

The fastest way to find it is to search your model number plus "filter reset button" on Samsung's website. Your model number is a combination of letters and numbers printed on a sticker inside the fridge, usually on the back wall or on the side wall near the top. Write it down and search for it on samsung.com/us/support — the result will show you a diagram or photo of where the button is on your exact fridge.

Replace the water filter before resetting the light

The filter light tells you when the cartridge has been in use long enough that its filtering power is declining. You should replace the physical filter first, then reset the light. If you reset the light without replacing the filter, the fridge will not remind you when the old filter actually needs changing, and your water quality will suffer.

Most Samsung water filters are located behind a panel in the fridge, usually in the bottom right corner or in the upper right corner, depending on the model. The cartridge twists out counterclockwise by hand. Before you install the new one, run water through the dispenser for about five seconds to flush the line. Then twist the new filter in clockwise until it stops — do not force it. Once the new filter is in place, hold the reset button for three seconds.

What to do if the light does not turn off

If you hold the reset button for three seconds and the light stays on, the button may not be making contact, or the fridge's control board may need a restart. Unplug the refrigerator from the wall outlet and leave it unplugged for five minutes. This clears the fridge's memory and often resets the filter light without pressing any button. Plug it back in and check whether the light is off.

If the light is still on after the power reset, try holding the button again for a full five seconds instead of three. Some older Samsung models require a longer hold. If it still does not work, the control panel button itself may be stuck or broken, and you may need to contact Samsung support or a repair technician. Do not ignore a stuck filter light — it will not turn off on its own, and you will lose track of when your filter actually needs replacing.

Understand what the filter light means

The water filter light turns on after the fridge estimates that the filter has been in use for about six months or has filtered a certain volume of water — usually around 300 gallons. This is not a hard important date; the light is a reminder, not a warning that the water is unsafe. However, once the light is on, the filter's effectiveness begins to drop, and you should plan to replace it within a few weeks.

If you use your ice maker and water dispenser heavily, you may need to replace the filter sooner than six months. If you use them rarely, you might stretch it to eight or nine months. The light is Samsung's best guess based on average use. Resetting it tells the fridge to start counting down another six months from that point.

Find your model number quickly

Your Samsung fridge's model number is printed on a white or silver sticker and is usually located on the back wall of the fridge, near the bottom. It is also often on a sticker inside the fridge door frame or on the side wall. The number looks like this: RF28R7201SR or RS25J500DSR — it starts with letters and includes numbers.

Once you have the model number, go to samsung.com/us/support, click "Refrigerators" in the product category, and search for your model. The support page will show you the manual, filter replacement instructions, and a diagram showing exactly where your filter reset button is located. This takes two minutes and saves you from guessing.

Frequently Asked Questions

How often should I reset the water filter light?

Reset it only after you physically replace the water filter cartridge. The light is designed to turn on roughly every six months of use. Once you install a new filter, hold the reset button to tell the fridge to start counting down another six months.

Can I reset the filter light without replacing the filter?

You can, but you should not. Resetting the light without replacing the filter means the fridge will not remind you when the old filter actually needs changing. Your water quality will decline, and you will lose track of the filter's age.

What if I cannot find the reset button on my fridge?

Look up your model number on samsung.com/us/support. The support page includes a manual with a diagram showing the button's exact location. If your fridge is very old, the button may be in an unusual spot, and the manual is the only reliable way to find it.

Does the filter light reset automatically after I replace the filter?

No. You must hold the reset button for three seconds after installing the new filter. The light will not turn off on its own, even with a brand-new cartridge in place.

What if the reset button is broken?

If holding the button for five seconds does not work, and unplugging the fridge for five minutes does not reset the light, the control panel button may be stuck or the control board may need repair. Contact Samsung support or a local appliance repair technician.
