Check that the CO2 is full and the valves are open. The easiest way to check is the content gauge of your pop system. It should read above empty. For cylinders do not judge if a tank is full by the weight. An empty tank can weigh as much or more than an empty tank. Ensure that there is lots of ice on the cold plate. If you can see the bottom of the ice well or the cold plate, there is not enough ice. Add more ice. As a general rule there should be at least 6 inches of ice on the cold plate. Make sure the carbonator is plugged in and that it has cycled at least one time. There is always a chance that the syrup to water ratio could be off or there is irregular water pressure.
