No water to icemaker

The replacement valve was identical to the old one, so I didn't have to use any of the adapter parts sent with the new valve. This made the installation rather simple. After removing the back cover on the lower part of the refrigerator, I turned off the water and electrical supplies, and removed the water supply line to the valve. Then I removed the two screws securing the valve to the refrigerator. Next, I removed the two electrical connections from the valve, and unscrewed the plastic nuts holding the tubing to the valve. I didn't have to use a wrench to do this as they were hand tight, so when I attached the tubing to the new valve I tightened the nuts hand tight. This seemed to be sufficient and avoided the possibility of stripping the nuts. After checking for leaks, I attached the electrical connections and secured the new valve to the refrigerator. Then I attached the water supply line, but before replacing the back cover, I turned on the refrigerator, and let it cycle through it's first load of ice.
