The filter light resets after you replace the water filter cartridge

Your Samsung refrigerator's filter light turns on when the water filter has been in use for about six months or 300 gallons of water, whichever comes first. The light does not turn off by itself—you have to manually reset it after you install a new filter. The reset process takes less than a minute and requires no tools.

The exact steps depend on which Samsung model you own, because the control panel location varies. Some fridges have the reset button on the front panel near the water dispenser, others have it inside the fridge on the upper wall, and some models use a button on the ice maker itself. This guide covers the three most common locations.

Key Takeaways

  • The filter light indicates the cartridge has reached its six-month or 300-gallon limit and needs replacement, not that the water is unsafe to drink.
  • You must physically replace the filter cartridge before resetting the light, or the light will turn back on within hours.
  • The reset button location depends on your model: check your owner's manual or the fridge itself for a button labeled "Filter Reset" or an icon showing a water droplet.
  • Holding the reset button for three to five seconds clears the light on most Samsung models; some require a shorter press.
  • If the light does not turn off after reset, the button may not have been held long enough, or your model may use a different reset method.

Locate the filter reset button on your specific model

Before you reset anything, find where the button is on your fridge. Samsung places it in three main locations depending on the model year and style.

Front control panel: Look on the right side of the fridge door, near the water and ice dispenser buttons. The button is usually small, round, and labeled "Filter Reset" or marked with a water droplet icon. This is the most common location on French-door and side-by-side models made in the last ten years.

Inside the fridge: Open the fridge door and look at the upper right wall, just below the ceiling. Some models have the reset button mounted here, often inside a small plastic housing. You may need to remove a cover or panel to access it.

On the ice maker: If your fridge has an ice maker in the freezer, the reset button may be on the ice maker unit itself, usually on the front or side. Check your owner's manual if you cannot find it in the first two locations.

If you cannot locate the button by looking, your owner's manual will show you exactly where it is. You can also find the manual online by searching "Samsung [your model number] manual" — the model number is on a sticker inside the fridge, usually on the upper wall or the back wall.

Replace the water filter before resetting the light

The filter light will only stay off if you have actually installed a new filter cartridge. If you reset the light without replacing the filter, it will turn back on within a few hours or a few days, depending on your model.

To replace the filter, locate the cartridge housing. On most Samsung fridges, this is in the upper right corner inside the fridge, or in the lower right corner of the fridge exterior (behind a panel). Turn the old cartridge counterclockwise by hand until it comes free, then pull it straight out. Insert the new cartridge straight in and turn it clockwise until it stops—do not force it.

Run water through the dispenser for 30 seconds to flush the new filter before you reset the light. This removes air from the line and any loose carbon dust from the cartridge.

Press and hold the reset button for three to five seconds

Once the new filter is installed and flushed, press the reset button. On most Samsung models, you need to hold it down continuously for three to five seconds. You will hear a beep or see the light blink when the reset is complete.

Release the button and check whether the filter light has turned off. If it has, the reset was successful. If the light is still on, try holding the button again for a full five seconds—sometimes a shorter press does not register.

Some older Samsung models require only a quick press (one second) rather than a hold. If holding it for five seconds does not work, try a single quick tap instead.

What to do if the light does not turn off

If the filter light stays on after you have replaced the filter and pressed the reset button, the most common cause is that the button was not held long enough. Try again, this time counting to five slowly while holding the button down.

The second most common cause is that the new filter cartridge is not fully seated. Remove it, check that the housing is clean and free of debris, and reinstall the cartridge. Make sure it clicks or stops turning when you twist it clockwise—this means it is fully locked in place.

If the light still will not turn off after you have tried both of these steps, your model may use a different reset method. Check your owner's manual, or contact Samsung support with your model number. They can walk you through the exact process for your specific fridge.

Understanding what the filter light actually means

The filter light is a maintenance reminder, not a safety warning. It turns on based on time and water volume, not on whether the water quality has actually degraded. You can continue to drink the water after the light comes on, but the filter will become less effective over time.

Samsung recommends replacing the filter every six months for best taste and odor removal. If you use very little water, you might go longer between replacements. If you use a lot of water or have hard water in your area, you might need to replace it sooner than six months.

The filter light is separate from any error codes that might appear on your fridge's display. If you see an error code like "5E" or "1E" along with the filter light, that indicates a different problem and you should contact a technician.

Frequently Asked Questions

Can I turn off the filter light without replacing the filter?

You can reset the light, but it will turn back on within hours or days if you have not installed a new filter. The light is tied to the filter cartridge itself on most Samsung models, so it will not stay off without a genuine replacement. Resetting without replacing is not a permanent solution.

What type of filter do I need to buy?

You need a Samsung genuine replacement filter or a compatible third-party filter designed for your specific model. The model number is on a sticker inside your fridge. Search for that number plus "water filter" to find the correct cartridge. Using the wrong filter size or type can cause leaks or poor water quality.

Where do I buy a replacement filter?

Samsung filters are sold at most appliance stores, big-box retailers like Home Depot and Lowe's, online marketplaces, and directly from Samsung. Prices vary by retailer and model, typically ranging from $30 to $80. Check your owner's manual for the exact part number to may support you order the right one.

Do I need to turn off the water supply before replacing the filter?

No. Samsung filters are designed to be replaced without shutting off the water. You may see a small amount of water drip when you remove the old cartridge, so have a towel ready. If water continues to spray after you remove the cartridge, close the shutoff valve under the sink or behind the fridge until you have the new one installed.

Why does my filter light keep coming back on?

The most common reason is that the new filter is not fully seated in the housing. Remove it, clean the housing, and reinstall it firmly until it stops turning. If you have replaced the filter correctly and the light still comes back on within a few days, the reset button may not have been held long enough, or your model may require a different reset method—check your manual or contact Samsung support.
