How often should I replace the water filter, and how do I reset the filter status?

You should change the water filter every six months, or after 200 gallons/757 liters of water has flowed through the system. After replacing the filter cartridge, press and hold the Water Filter button on the Ice & Water Dispenser control panel for three seconds until the display changes from 'Red' to 'Green' to reset the status.
