How to Reset a Samsung Refrigerator Water Filter Light

This guide shows you how to turn off the water filter indicator light on your Samsung refrigerator after replacing the filter. The reset process takes less than a minute and requires no tools. You’ll need to know your refrigerator’s model type (with or without an ice maker in the door) to choose the correct steps.

What You’ll Need

• A new Samsung water filter (if you haven’t already installed it)
• Access to the control panel or dispenser area
• A small towel to catch any water drips (optional but helpful)

Step-by-Step

For Models with a Dispenser Control Panel (Most Common)

1. Install the new filter – Remove the old filter by turning it counterclockwise (about a quarter turn) and pulling it straight out. Insert the new filter, push it in firmly, and turn it clockwise until it locks. Run 2–3 gallons of water through the dispenser to purge air and any carbon fines.
2. Locate the control panel – On the front of the dispenser, you’ll see buttons for water, ice, and a lock. The exact layout varies by model, but the reset is always done using these buttons.
3. Press and hold the “Ice Maker” and “Filter” buttons – On most Samsung refrigerators, press and hold the Ice Maker and Filter buttons simultaneously for 3–5 seconds. The filter light will blink and then turn off. Release the buttons.
4. If the light stays on – Try pressing and holding the Ice Maker and Cold Water buttons for 3 seconds instead. Some newer models use this combination.
5. Confirm the reset – The red or orange filter indicator should go off. If it doesn’t, repeat the hold for a full 10 seconds.

For Models Without a Dispenser (Filter Inside the Fridge)

1. Locate the filter – It’s usually at the top right or bottom left inside the fresh food compartment. Twist it counterclockwise to remove, install the new one, and twist clockwise to lock.
2. Find the reset button – On the ceiling of the fridge compartment, near the filter housing, there is a small button labeled “Filter Reset” or a tiny pinhole. Press and hold it for 3 seconds.
3. If there’s no button – On some models, you hold the “Fridge” and “Freezer” buttons on the external dispenser for 3 seconds. If your fridge has no dispenser at all, consult your manual for the exact button combo.

For Models with a Smart Display (Family Hub)

1. Open the Family Hub screen – Tap the home icon on the display.
2. Go to Settings – Tap the gear icon, then select “Refrigerator” or “Water Filter.”
3. Select “Reset Filter” – Follow the on-screen prompts. The light will reset automatically.

Common Mistakes

• Holding the wrong buttons – The most common error is pressing the “Filter” button alone or with “Lock.” It must be the Ice Maker + Filter (or Ice Maker + Cold Water) combination on dispenser models.
• Not holding long enough – A quick tap won’t work. You need to hold for at least 3 seconds, sometimes up to 10.
• Resetting before installing the filter – The light will just come back on if you reset it without actually replacing the filter. Always install the new filter first.
• Forgetting to purge the water – If you don’t run water through the new filter, air bubbles can cause sputtering and the light may not reset properly on some models.
• Using the wrong reset method for your model – The button combo differs between models. If one combo doesn’t work, try the other before assuming the light is broken.

Tips

• Keep your manual handy – The exact button combo is listed in the troubleshooting section of your user manual. If you’ve lost it, search online for your model number (found on a sticker inside the fridge) + “water filter reset.”
• Replace the filter every 6 months – Samsung recommends changing the filter every 6 months or after 300 gallons (about 1,136 liters) of water, whichever comes first. The light is a reminder, not a sensor – it’s based on time/usage.
• Use genuine Samsung filters – Third-party filters may fit, but the reset light may not recognize them. If you use a compatible filter, the reset procedure is the same.
• Run the water after reset – Even after a successful reset, run 2–3 gallons of water to clear the system. This also helps prevent the light from flashing due to low pressure.
• If the light blinks rapidly – This can indicate a leak or a filter that isn’t seated properly. Remove and reinstall the filter, ensuring it locks into place.

Troubleshooting

The light won’t turn off after multiple attempts.

• Check the filter installation – Turn the filter clockwise until it stops. If it’s not fully seated, the fridge may not recognize it. Remove and reinstall.
• Power cycle the fridge – Unplug the refrigerator for 2 minutes, then plug it back in. This resets the control board. After it powers up, try the reset again.
• Try a different button combo – On some models, it’s Ice Maker + Filter; on others, it’s Ice Maker + Cold Water. Some older models use “Fridge” + “Freezer” for 3 seconds. Test each.
• Check if the light is actually blinking – A steady red light means the filter is due. A blinking light often indicates a different issue (like a water leak). If it’s blinking, inspect the water lines for leaks.
• If nothing works – The control board may need a firmware update (on smart models) or the light may be a hardware fault. Contact Samsung support with your model number.

Frequently Asked Questions

How long does the filter light stay on after reset?

It should turn off immediately after the correct button hold. If it stays on, the reset didn’t register – repeat the hold for 10 seconds.

Do I need to reset the light every time I change the filter?

Yes, the light is a manual timer. It doesn’t automatically detect a new filter, so you must reset it each time.

What if I don’t reset the light?

Nothing bad happens – the light will just stay on. The water will still work, but you’ll lose the reminder for the next filter change.

Can I reset the light without changing the filter?

Technically yes, but it’s not recommended. The filter is likely exhausted, and resetting without replacing it means you’ll be drinking water from an old filter.

Why is my filter light blinking red?

A blinking red light usually indicates a problem beyond just a filter reminder – often a water leak or a filter that’s not seated properly. Check the filter and water lines.

Does the reset process differ for a French door vs. side-by-side model?

Not usually – the button combo is the same for most dispenser models. The difference is mainly between models with a dispenser and those without. Check your manual if unsure.
