Slowly rotate the cartridge one-quarter turn counterclockwise to disengage. Gently twist until the cartridge is free from the base. DO NOT pull. There will be water in the filter cartridge, so it is normal for a small amount of water to spill out.<br><br>3.

DO NOT overtighten.<br><br>5. After the new filter cartridge is installed, the first full bucket of ice produced should be discarded. This will help clean the water system and clear air from the line.
