Location:
The electronic control board is located inside the rear of the dispenser. Access will also be needed to the temperature sensor, overflow tube temperature sensor, and liquid level probe located on the tank lid.
General:
This system controls the liquid level and water temperature of the dispenser. These two functions act independently of each other and should be tested separately.
