Replace the water filter in your Samsung refrigerator

Samsung refrigerator and water filter replacement

You need a clean water filter to get fresh, filtered water. We recommend that you replace the water filter every six months. The refrigerator's water filter light will let you know when those six months are up and should be reset after changing the filter.

Note: Only use Samsung Genuine Filters that are designed to work with your Samsung refrigerator. You can purchase them directly on our website. Do not use third-party water filters, which may leak and damage the refrigerator.

Determine which water filter you need

There are three types of Samsung water filters, so you’ll want to make sure you're choosing the correct one for your fridge.

First, locate the filter in your fridge model. The location will vary depending on your model, so please check your user manual if you’re unsure. Then, check the model number on the filter itself. This will let you know which of the following filter types you’ll need to purchase.

Water filter model HAF-CIN
Water filter model HAF-QIN
Water filter model HAFCU1

Replace the water filter

Replacing your water filter is simple and should only take a few minutes. If you’re unsure about whether you need to replace the filter, check the indicator light on your fridge.

After six months, the indicator will change. On some models it lights up when it wasn't lit before, and on others it will turn red. At this time, you should change the filter right away. 

HAF-CIN and HAF-QIN filter types:

  1. First, turn off the water supply and then locate the filter. If you are unsure where it is, please consult your user manual.

  2. Open the water filter cover and then rotate the old filter counterclockwise to unlock it.

  3. Then, pull it straight out to remove it from the filter housing.

  4. To insert the new filter, first remove the protection cap from the top of the filter. Then, push it straight into the filter housing and turn it clockwise.

  5. Make sure the lock symbol matches up with the indicator line.

HAFCU1 filter types:

  1. First, turn off the water supply and then locate the filter. If you are unsure where it is, please consult your user manual.

  2. To remove the old filter, twist it to the left. This will unlock it.

  6. After replacing your filter, dispense a few gallons of water to flush out any impurities or air. Then, make sure to reset the water filter light on your fridge. Please see the next sections for more information.

Reset the water filter light

The water filter light on your fridge operates on a timer and will turn on after six months. For models where the indicator is always lit, it will turn red after six months.

Depending on the quality of the water in your area and the amount of water you dispense, you may want to change the filter more or less frequently than the light suggests. To determine if a new filter is needed, dispense water first with the filter installed and then with the filter removed. If the speed the water dispenses at is significantly different, you should replace the filter whether the indicator is lit or not.

Note: Some models have panels that automatically lock after inactivity. On these types of panels, you will need to unlock the panel and then perform the following steps before the panel locks again.

You can use the following steps to reset the filter light:

  1. Find the Filter Reset button on the control panel, if it's available. It is sometimes the secondary function of another button on the panel.

  2. Once located, touch and hold the correct button for three seconds until the light resets.

  3. The filter icon will either turn off or change back to its normal color when it's reset. This starts the six month timer over again.
