Many side-by-side refrigerators come with water and ice dispensers in the door. You should prime the water system in the refrigerator after completing the installation or replacing the water filter. Priming a refrigerator's water dispenser is a matter of running water through the system until all the air is out of the water lines and the water is not cloudy. Priming the system ensures that you have clean drinking water and ice at your fingertips.
Open the freezer door and turn off the ice maker. Look for either a wire arm that you push up or a switch that you turn to the "off" position. This prevents running unfiltered water through the ice maker.
Hold a large drinking glass against the water dispenser paddle until water begins to spurt from the dispenser. This process begins filling the tank and running the water through the filter. Once the glass is full of water, empty the glass into a nearby sink.
Place the glass against the dispenser paddle again and continue filling the glass. The water will spurt and be discolored as the line is purged of air and the water begins flowing through the filter.
Continue filling the glass and emptying it until the water runs through the dispenser without air bubbles and the water is clear. Open the freezer door and turn on the ice maker.
