The reset button is usually inside the refrigerator, on the filter housing itself

Most Samsung refrigerators have a water filter reset button built directly into the filter head — the plastic housing where the filter cartridge sits. After you install a new filter, you press this button to tell the refrigerator that the filter is fresh and reset the usage counter. The light on your display will turn off once the reset is complete.

The exact location varies slightly by model. On many Samsung French-door and side-by-side models, the reset button is a small circular or rectangular button on the front of the filter housing, usually in the upper right corner of the refrigerator interior. On some models, it sits on top of the filter head. You may need to look closely or use a flashlight to spot it — it is often the same color as the housing and blends in.

If you cannot find a physical button on the filter housing, your model may use a different reset method, which we cover below.

Key Takeaways

  • The water filter reset button is a small button on the filter housing inside your refrigerator, usually in the upper right area or on top of the filter head.
  • You must press the reset button after installing a new filter cartridge, not before — pressing it on an old filter will silence the warning light without actually replacing the filter.
  • If your model does not have a physical button, you can reset the filter through the refrigerator's control panel or display screen using the menu options.
  • The reset light should turn off within a few seconds of pressing the button; if it stays on, the button may not have registered and you should try again.
  • Resetting the filter light does not clean or maintain the filter itself — it only resets the usage counter, so you still need to replace the cartridge on schedule.

Step-by-step: pressing the physical reset button

First, make sure you have already removed the old filter and installed the new one. The reset button tells the refrigerator that a fresh filter is in place, so pressing it before you swap the cartridge will silence the warning without actually filtering your water.

Locate the filter housing. Open your refrigerator door and look in the upper right corner of the interior, or check the top of the filter head if your model mounts the filter vertically. Some models hide the filter behind a small panel or cover — if you see a plastic door or trim piece in that area, gently pull or slide it to reveal the filter housing.

Find the reset button on the housing. It is typically a small circular or rectangular button, often recessed slightly so it does not get pressed by accident. It may be labeled "Reset" or have a small icon, but many are unmarked. If the housing has multiple buttons, the reset button is usually separate from the release button that holds the filter in place.

Press and hold the button for three to five seconds. You should hear or feel a small click. The water filter light on your display panel should turn off within a few seconds. If the light stays on, release the button, wait a moment, and try again — sometimes the button needs a firm, deliberate press to register.

Resetting through the control panel or display screen

If your Samsung refrigerator has a digital display panel on the door or inside the fridge, and you cannot find a physical reset button on the filter housing, you can reset the filter through the menu. The exact steps depend on your model, but the general path is the same.

Press the menu or settings button on your display. This is often labeled "Menu," "Settings," or "Options." Look for a button with a gear icon or similar symbol. Once you enter the menu, scroll or navigate to find "Water Filter," "Filter Status," "Filter Reset," or similar wording. Highlight that option and press select or enter. The display will usually ask you to confirm the reset. Select "Yes" or "Confirm," and the light should turn off.

If you are unsure which button opens the menu on your specific model, check the user manual or look for a label printed on or near the control panel. Samsung also publishes model-specific guides on their support website — search for your refrigerator's model number (usually found on a sticker inside the fridge or on the back) plus "water filter reset" to find the exact instructions for your unit.

What to do if the light stays on after reset

If you pressed the reset button or went through the menu and the water filter light is still on, the reset may not have registered. Try pressing the button again, this time with a firmer, more deliberate press. Hold it for a full five seconds and listen for a click. Sometimes the button is stiffer than expected or requires more pressure than you might think.

If the light still does not turn off, check that you actually installed a new filter. If the old filter is still in place, the refrigerator will not reset — it knows the filter has not been changed. Remove the old filter, confirm it is truly spent (it should be discolored or clogged), and install the new one before trying the reset again.

If you have confirmed the new filter is installed and the reset button is not working, the button itself may be faulty or stuck. In that case, use the control panel reset method instead. If neither method works, the refrigerator's filter sensor may need service — contact Samsung support or a refrigerator repair technician.

Understanding what the reset button actually does

The reset button does not clean, flush, or maintain the filter. It straightforward resets the usage counter inside the refrigerator's computer. When you press it, you are telling the fridge "I have just installed a new filter, so start counting the days and gallons of water used again from zero."

The water filter light comes on because the refrigerator tracks how long the filter has been in use. Most Samsung filters are rated for six months or 300 gallons of water, whichever comes first. After that time, the light turns on to remind you to replace the cartridge. Pressing reset does not extend the life of the old filter or make a worn filter work better — it only silences the warning light.

If you press reset without actually replacing the filter, the light will turn off, but your water will not be filtered properly. The old filter will continue to degrade, and you will not get a reminder to change it. Always replace the cartridge first, then reset.

How often you need to replace the filter

Samsung water filters are typically rated for six months of use or 300 gallons of water, whichever comes first. If your household uses a lot of water or has particularly sediment-heavy tap water, you may need to replace the filter sooner. If you use very little water, the filter may last closer to six months even if you have not reached 300 gallons.

When the light comes on, that is your signal to order a replacement. Samsung filters are sold under the brand name "Aqua-Pure" and are available from Samsung directly, from appliance retailers, and from online marketplaces. Make sure you order the correct model number for your refrigerator — the model number is usually printed on the filter housing or in your user manual.

Replacing the filter is straightforward: turn the old cartridge counterclockwise to release it, pull it straight out, and push the new one in until it clicks. Then press the reset button. The whole job takes about two minutes.

Frequently Asked Questions

Can I reset the filter light without replacing the filter?

Yes, you can press the reset button without replacing the filter, and the light will turn off. However, you should not do this. The light is a reminder that your filter is no longer effective. Silencing it without replacing the cartridge means your water will not be filtered, and you will lose track of when the filter actually needs changing.

Where exactly is the reset button on my model?

The reset button is on the filter housing itself, usually in the upper right corner of the refrigerator interior or on top of the filter head. If you cannot find it after looking carefully, your model may use a digital menu reset instead. Check your user manual or search your model number plus "water filter reset" on Samsung's support website.

What if I press the reset button and nothing happens?

Try pressing it again with more force and hold it for a full five seconds. If the light still does not turn off, make sure a new filter is actually installed — the refrigerator will not reset if the old filter is still in place. If both are true and the button still does not work, try resetting through the control panel menu instead.

How do I know which filter to buy for my refrigerator?

Your refrigerator's model number is printed on a sticker inside the fridge, usually on the back wall or on the side wall. Write down that number and search it on Samsung's website or on the filter housing itself — the correct filter model will be listed. Most Samsung refrigerators use the same filter type, but some older or specialty models differ, so always confirm before ordering.

Does resetting the filter clean it or make it last longer?

No. Resetting the filter only resets the usage counter. It does not clean the cartridge, extend its life, or improve its performance. The filter itself wears out over time and must be physically replaced. Pressing reset just tells the refrigerator to start counting again from zero.
