LG LTCS24223S how to replace the water filter
When the Filter Exchange indicator turns on, about every 6 months, when the water dispenser output decreases, or when the ice cubes are smaller than normal.
You need
- Cloth to catch water
- Replacement filter ADQ72910906
Steps
- Turn off the household water supply.
- Turn the old filter counterclockwise, then pull it down and out. Rotate it down completely before pulling it out of the manifold hole, and hold it upright to keep remaining water from spilling.
- Remove the red cap from the new filter.
- Insert the new filter into the filter receptacle on the left side of the refrigerator compartment.
- Push the filter up into the receptacle and rotate it clockwise until it locks and cannot be turned further.
- Replace the shelf in its initial position and turn on the household water supply.
- Dispense 2.5 gallons (9.46 liters) of water in cycles of 30 seconds on and 60 seconds off, pressing and releasing the dispenser pad.
- Open the refrigerator door and check the shelf area for water leaks.
Replacing the filter drains about 1 oz (25 cc) of water. Keep the substitute cap: if the filter is removed and not replaced, reinstall the cap to prevent water leaks from the filter housing.
