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.
