Drain
Functions:
Safety valve: opens towards the drain if the pressure exceeds 16-19 bar
Filling the circuit: the solenoid valve opens (drain position), the pump is controlled and automatically refills the
circuit by expelling the air in the pipe
Draining the unit: before the unit descends, it opens briefly, releasing the pressure created to prevent the unit from
spraying and making the pad drier
Coffee product: when a coffee beverage is selected, the pump is charged briefly during the grinding process and the
valve assumes the drain position for hot water to pass through the pipes.
