An automatic fill system for a beverage dispenser includes a sensor system for monitoring the beverage level in the dispenser. The sensors are wired in series with a level control board mounted inside the frame of the beverage dispenser. Sensing points are connected in an electrical circuit for maintaining the proper water to beverage concentrate ratio in the mixing hopper of the beverage dispenser. Resistance in the circuit is monitored so that when the resistance in the circuit reaches a predetermined value, a relay and solenoid open to divert water to the mixing hopper for mixing with the beverage concentrate. Sensors in the hopper shut off the dispenser when the beverage level in the hopper exceeds maximum and minimum levels.
