AUTOMATIC OPERATION
Pressing BREW button energizes the solenoid valve, allowing water from an external water supply to flow into the basin pan and then into the hot water tank. This forces an identical amount of hot water out of the tank and through the spray head into the brew chamber
The solenoid uses a flow control device so that flow is consistent between 20 p.s.i. and 90 p.s.i.
Length of time the solenoid is open is controlled by the timer.
