If the beverage does not dispense, follow these troubleshooting steps. First, identify what exactly does not dispense - Syrup, Carbonated Water, Plain Water, or Both. Make sure the water is turned on and water pressure is appropriate.
Note: Appropriate water pressure is 50 psi-60 psi. If you have low water pressure a water booster will be required. The booster will boost the water pressure up to 90 psi-110 psi. A water regulator will be required. Reference installation portion.
