How to replace water filter on lg refrigerator?


Replacing the water filter on an LG refrigerator is an essential maintenance task that ensures clean and fresh-tasting water. In this article, we will guide you through the step-by-step process of replacing the water filter on your LG refrigerator, ensuring that you can enjoy the benefits of filtered water for you and your family.

Step 1: Identify the Water Filter Location

The first step is to locate the water filter on your LG refrigerator. The filter is typically located in the upper right-hand corner of the refrigerator compartment. Look for a rectangular or cylindrical cartridge that is connected to the water supply line.

Step 2: Turn Off the Water Supply

Before replacing the water filter, it is important to turn off the water supply to prevent any leaks or spills. Locate the shut-off valve behind the refrigerator or under the sink and turn it clockwise to shut off the water supply.

Step 3: Remove the Old Water Filter

Once the water supply is turned off, you can proceed to remove the old water filter. Twist the filter counterclockwise to unlock it, and then pull it straight out. Be prepared for a small amount of water to spill out, so it’s a good idea to have a towel or a container ready to catch any drips.

Step 4: Prepare the New Water Filter

Before installing the new water filter, it is important to prepare it properly. Remove the protective cap from the new filter and locate the O-rings on both ends. If the O-rings are missing or damaged, transfer them from the old filter to the new one.

Step 5: Install the New Water Filter

Insert the new water filter into the filter housing, making sure it is aligned correctly. Twist the filter clockwise to lock it in place. You should feel it lock securely. Give it a gentle tug to ensure it is properly installed.

Step 6: Turn On the Water Supply

Once the new water filter is securely installed, it’s time to turn the water supply back on. Locate the shut-off valve and turn it counterclockwise to restore the water flow. Check for any leaks around the filter and tighten the connections if necessary.

Step 7: Flush the Water Filter

To ensure the best water quality, it is recommended to flush the new water filter before using it. Run several gallons of water through the dispenser to remove any carbon fines or air bubbles. This will help to eliminate any initial cloudiness or off-taste in the water.

Step 8: Reset the Water Filter Indicator

Many LG refrigerators have a water filter indicator that needs to be reset after replacing the filter. Consult your refrigerator’s manual to find out how to reset the indicator. This step is important to ensure that you receive accurate notifications for future filter replacements.


Replacing the water filter on your LG refrigerator is a straightforward process that can be done by following these simple steps. Regularly replacing the water filter will help maintain the quality and taste of the water dispensed from your refrigerator. Remember to consult your refrigerator’s manual for specific instructions and recommendations.
