How do I change the water filter?

Turn off the ice maker, then push on the end of the filter to remove it. Slide the old cartridge out and discard it. Using the alignment guide, slide the new PureSource 3™ filter cartridge gently into the housing until it stops, then push firmly until you hear a click. After installation, press a glass against the water dispenser to check for leaks and continue flushing for about 4 minutes. Finally, press and hold the Water Filter button for three seconds until the display changes from Red to Green. (Page 18)
