Reset the filter indicator light after you install a new filter

Most Samsung refrigerators have a water filter light that tells you when the filter needs replacing. Once you install a new filter, you need to reset this light manually — it does not turn off by itself. The reset process takes less than a minute and requires no tools.

The exact steps depend on your model's control panel. Some Samsung fridges have a physical reset button on the filter housing itself. Others use a button on the refrigerator's main display panel. A few models let you reset through the digital touchscreen menu. This guide covers all three methods so you can find the one that matches your fridge.

Key Takeaways

  • The water filter light does not reset automatically after you install a new filter — you must reset it by hand.
  • Most Samsung models have a reset button either on the filter housing under the sink or on the refrigerator's control panel.
  • Holding the reset button for three to five seconds until the light changes color or blinks confirms the reset worked.
  • If your fridge has a digital display menu, you can also reset the filter light through the settings without touching a physical button.
  • Resetting the light does not affect how the fridge runs — it only resets the timer that tracks filter age.

Find your filter and locate the reset button

The water filter on most Samsung refrigerators sits in one of two places: inside the fridge in the upper right corner, or under the sink in the water line. Check your owner's manual to confirm which model you have, but the reset button location follows the filter location.

If your filter is inside the fridge, look in the upper right corner of the interior. You will see a cylindrical filter cartridge. A small reset button sits directly on or near the filter housing — it is usually red, blue, or black and about the size of a pencil eraser. If your filter is under the sink, the reset button is on the filter housing mounted to the water line. Once you locate the button, you are ready to reset.

Reset using the physical button on the filter housing

This is the most common reset method on Samsung fridges. After you have installed your new filter cartridge, press and hold the reset button on the filter housing itself. Hold it down for three to five seconds until you see the light change — it usually goes from red to blue or from on to off, depending on your model.

Release the button and wait a few seconds. The light should now show that the filter is new and the timer has restarted. If the light does not change after five seconds, try holding the button for a full ten seconds. Some older Samsung models require a longer press. If the light still does not respond, move to the control panel method below.

Reset using the control panel button

Newer Samsung refrigerators often have a dedicated filter reset button on the main control panel, usually located on the front of the fridge near the ice and water dispenser. Look for a button labeled "Filter Reset," "Water Filter," or sometimes just a water droplet icon. The button may be recessed slightly into the panel.

Press and hold this button for three to five seconds. You should hear a beep or see the filter light on the display change color — typically from red to blue. Release the button and check that the change has taken effect. If your model has a digital display screen, the filter status should update within a few seconds. If nothing happens, your fridge may use the menu-based reset instead.

Reset through the digital display menu

Some Samsung models with touchscreen displays let you reset the filter through the settings menu instead of a physical button. Press the "Menu" or "Settings" button on your refrigerator's display panel. Navigate to "Water Filter" or "Filter Status" — the exact wording varies by model year.

Look for an option that says "Reset Filter," "Reset Water Filter," or "Filter Replacement." Select it and confirm when prompted. The display should show a message confirming the reset is complete, and the filter light should change color or turn off. If you cannot find a filter option in the menu, your model likely uses one of the physical button methods above. Refer to your owner's manual for the exact menu path on your specific model.

Confirm the reset worked

After you reset, the filter light should change appearance. On most Samsung fridges, a red light turns blue, or a lit light turns off completely. Some models show a percentage that resets to 100 percent. Wait a few seconds after pressing the reset button — the change may not happen when ready.

If the light does not change after waiting, try the reset process again. Make sure you are holding the button long enough — three to five seconds is the standard, but some models need up to ten seconds. If you have tried all three methods and the light still will not reset, the button itself may be stuck or faulty. Contact Samsung support with your model number, or consult your owner's manual for troubleshooting steps specific to your fridge.

What to do if you cannot find the reset button

If you have looked in all the places above and cannot locate a reset button, check your owner's manual first. The manual will show you exactly where the button is on your specific model — sometimes it is in an unexpected spot or labeled differently than you might expect.

You can find your manual online by searching "Samsung [your model number] manual" — the model number is usually on a sticker inside the fridge or on the back. If the manual shows no reset button at all, your fridge may reset the filter light automatically after a certain number of days or gallons of water used. Some very old Samsung models do not have a manual reset option. In that case, the light will turn off on its own once the timer reaches its limit.

Frequently Asked Questions

Do I have to reset the filter light right after I install a new filter?

Yes, you should reset it as soon as the new filter is in place. The light tracks how long the filter has been in use, so resetting it tells the fridge that you have just installed a fresh filter. If you do not reset it, the light will continue counting down from where the old filter left off, and you may miss the actual time to replace the filter.

What happens if I reset the filter light but do not actually install a new filter?

The fridge will not know that the old filter is still in use. The light will count down again as if you had installed a new one, and you may use a worn-out filter longer than is safe. This can affect water taste and quality. Always install a new filter before resetting the light.

Can I reset the filter light from my phone or a remote app?

Some newer Samsung smart fridges with Wi-Fi connection let you monitor filter status through the SmartThings app, but most do not allow you to reset the light remotely. You will need to reset it in person using one of the methods above. Check your manual to see if your model has smart home features.

The reset button is stuck and will not press down. What should I do?

Do not force it — you could break the button. Try gently wiggling it side to side while explore light pressure. If it still will not move, the button may be frozen or faulty. Contact Samsung support or a local appliance repair service. In the meantime, you can still use your fridge normally; the light just will not reset until the button is fixed.

How often do I need to reset the filter light?

You reset the filter light once every time you install a new filter cartridge. Most Samsung filters last six to twelve months depending on water usage. When the light turns red or alerts you, that is when you buy a new filter, install it, and reset the light. You do not reset it at any other time.
