How to Reset the Water Filter Light on Your Samsung Refrigerator

Reset the filter indicator after you install a new filter

After you put a new water filter into your Samsung refrigerator, the filter indicator light will not turn off by itself. You have to reset it manually so the refrigerator knows it is counting down from a fresh filter. The reset button or menu option is different depending on your model — some have a physical button you hold for three seconds, others use the control panel display.

The reason Samsung requires this step is practical: the refrigerator cannot tell whether the filter inside is actually new or old. It only tracks time and water flow. Resetting tells the machine "start the timer again from zero." If you skip this step, the filter light will stay on even though your filter is fresh, and you will get false warnings when the filter still has months of life left.

Key Takeaways

• Most Samsung models reset the filter light through the control panel display by pressing and holding a button labeled "Filter" or "Reset" for three seconds until the light blinks or disappears.
• Some older or French-door models have a physical reset button on the filter housing itself that you press after installation.
• Check your refrigerator's model number on the back wall or inside the door frame, then look up the exact reset steps in your manual or on Samsung's support site.
• The filter light will return after roughly six months or 300 gallons of water, whichever comes first, depending on your water quality and usage.

Find your model number and locate the reset control

Your Samsung model number is printed on a sticker inside the refrigerator, usually on the back wall near the top or on the inside of the door frame. It starts with "RF", "RS", "RH", or "RT" followed by numbers. Write it down or take a photo — you will need it to find the exact reset instructions for your machine.

Once you have the model number, go to samsung.com/us/support, enter it in the search box, and download the user manual as a PDF. The manual will show you a diagram of your control panel and tell you exactly which button to press and how long to hold it. If you cannot find the manual online, call Samsung customer service at 1-800-726-7864 and they will walk you through it over the phone.

Reset through the control panel display

On most modern Samsung refrigerators, the reset control is on the front panel near the ice and water dispenser buttons. Look for a button labeled "Filter", "Reset", or sometimes just an icon that looks like a water droplet or filter symbol. Press and hold this button for three seconds. You will usually see the light blink, dim, or disappear entirely — that means the reset worked.

Some models require you to press the button once to enter a menu, then press it again to confirm the reset. Others have a small screen that displays "Filter Reset" or "Filter OK" when you are done. If nothing happens after three seconds, try holding it for five seconds instead. If the light is still on after that, check your manual again — a few older models use a different sequence, such as pressing two buttons at once.

Reset a physical filter button on the filter housing

Older Samsung models and some side-by-side refrigerators have a small reset button built into the filter cartridge housing itself, usually located inside the refrigerator near the top right or bottom right corner. After you screw in the new filter, look for a small red or black button on the filter cover. Press it firmly until you hear a click or feel it pop inward.

This type of reset is mechanical — it does not depend on electronics or batteries. Once you press it, the light should go off immediately. If it does not, make sure the filter is screwed in all the way. A loose filter can trigger the light even after you reset the button. Tighten it by hand and try the reset button again.

What to do if the filter light stays on after reset

If you have held the button for the full time and the light is still on, the most common cause is that the filter itself is not installed correctly. Remove the filter, check that the rubber gasket or seal is clean and properly seated, and screw it back in firmly. Then try the reset again.

A second possibility is that you are pressing the wrong button or holding it for the wrong length of time. Go back to your manual and follow the steps exactly as written. Some models are sensitive to timing — if you release too early, the reset does not register. If the light still will not turn off after a second attempt, the control panel may have a fault. Contact Samsung support with your model number and they can arrange a service visit or replacement if the refrigerator is still under warranty.

When the filter light comes back on

After you reset the filter light, it will stay off for roughly six months under normal household use. The exact timing depends on how much water you dispense and how hard your water is. Hard water clogs filters faster, so the light may come on in four or five months. Soft water or light use may stretch it to eight months.

When the light comes back on, it is time to order a replacement filter. Samsung filters are sold under the part numbers DA29-00003G, DA29-00003A, DA61-00159A, and others depending on your model. You can buy them from Samsung directly, from appliance parts retailers, or from online marketplaces. Always check your manual to confirm which part number fits your refrigerator — using the wrong filter can damage the water system or let unfiltered water through.

Frequently Asked Questions

Do I have to reset the filter light, or will it turn off on its own?

No, it will not turn off by itself. The light stays on until you manually reset it through the control panel or the physical button. This is by design — Samsung wants you to confirm that you have actually installed a new filter, not just ignored the warning.

What happens if I do not reset the filter light?

The light will stay on, but the water will still flow and the refrigerator will still work normally. The light is just a reminder. However, you will lose the ability to know when the filter actually needs replacing, because the light will not turn on again at the right time. It is worth the 30 seconds to reset it properly.

Can I reset the filter light without installing a new filter?

Technically yes, but you should not. Resetting the light tells the refrigerator to start a new countdown timer. If you reset without changing the filter, you will go months without a warning when the old filter becomes clogged and stops working. Always install a new filter before you reset the light.

My refrigerator has a touchscreen. How do I reset the filter on that?

Touchscreen models usually have a "Settings" or "Appliance" menu. Tap it, look for "Water Filter" or "Filter Status", and select "Reset" or "Replace Filter". The exact path varies by model, so check your manual or call Samsung support with your model number for the step-by-step sequence.

Is there a way to know how much filter life is left before the light comes on?

Most Samsung refrigerators do not display a percentage or countdown. The light simply turns on when the timer or water flow sensor reaches its limit. Some newer models with touchscreens may show "Filter Status: Good" or similar, but they do not give you a precise number of gallons or days remaining.
