Functions:
Safety valve: serves as safety valve by opening towards the discharge when the pressure exceeds 16-19 bar.
Circuit charging: the solenoid valve opens (discharge position), the pump is activated and automatically recharges
the circuit, discharging any air out of the conduit.
Assembly discharge: before the assembly comes down, it opens briefly to discharge the accumulated pressure and
avoiding spraying from the assembly and keeping the plug nut drier
Coffee product: when a coffee product is selected, the pump briefly charges during the grinding phase, the valve
goes into discharge mode to bring hot water back into the conduits.
