- A new, LG-approved water filter (check your refrigerator’s manual for the correct model).
- A clean towel or cloth.
-
Remove the Old Filter:
- Inside the Refrigerator: Open the filter compartment door. Twist the old filter counterclockwise (usually about 90 degrees) to release it. Gently pull the filter straight out. Some water may spill, so have the towel ready.
- Base Grille: Open the grille. Twist the filter cover (if applicable) to release the filter. Then, rotate the filter itself counterclockwise to unlock it and pull it out.
- External: Locate the filter housing. Depending on the model, you may need to push a release button or turn a valve to release water pressure before removing the filter. Carefully unscrew the old filter.
-
Prepare the New Filter:
- Remove the new filter from its packaging.
- Remove the protective caps from the end of the new filter.
-
Install the New Filter:
- Insert the new filter into the filter housing.
- Twist the filter clockwise to lock it into place. Ensure it is securely fastened.
- Close the filter compartment door or grille.
-
Flush the System:
- Dispense water from the water dispenser for approximately 5 minutes (about 2.5 gallons). This will flush any air or carbon particles from the new filter. The water may initially appear cloudy or discolored – this is normal.
- Check for leaks around the filter housing.
-
Reset the Filter Indicator Light:
- Refer to your refrigerator’s user manual for instructions on how to reset the filter indicator light. The reset procedure varies depending on the model. Common methods involve pressing and holding a button labeled “Filter Reset,” “Water Filter,” or similar for 3-5 seconds.
Common Mistakes to Avoid
Replacing the water filter is a straightforward process, but it’s essential to avoid common mistakes to ensure optimal performance and prevent damage to your refrigerator.
- Using a Non-Approved Filter: Always use an LG-approved or compatible filter. Using a generic or low-quality filter can compromise water quality and potentially damage the refrigerator.
- Forcing the Filter: If the filter doesn’t seem to fit or turn easily, double-check that you have the correct model and are inserting it correctly. Forcing the filter can damage the housing and prevent proper sealing.
- Skipping the Flushing Step: Flushing the system after installing a new filter is crucial to remove air and carbon particles. Skipping this step can result in cloudy or discolored water and reduced water flow.
- Not Resetting the Indicator Light: Failing to reset the filter indicator light will not accurately track the filter’s lifespan, and you may not know when to replace it again.
