How do I change the water filter?

Shut off the water supply, then turn the water filter about 1/4 turn counter-clockwise and pull it out of the case filter. Insert the new filter into the filter case, push it in, and turn it clockwise until it locks. Touch the Crushed/Hold 3 sec for Filter Reset button for about 3 seconds to reset the water filter. If you turned off the water supply, turn it back on.
