Brew group valve

(3 - 5 bars)

Needle

Solenoid pilot function:

Brew group drain:

before the group is lowered, the solenoid pilot opens brieﬂy creating a depression

that in turn opens the valve in the opposite direction from dispensing, allowing any

water left in the group to be drained and keeping the pad dry.

Coffee ready after steam:

when a coffee or water are selected, the solenoid pilot opens the drain valve

to lower pressure in the heater.

Prime heater:

after a period in standby or when the appliance has not been used for an extended period

(1st coffee), the pump loads brieﬂy during grinding to get rid of any water between the

heater pin and heater, and to pre-heat the elements.

Fill circuit:

the solenoid pilot discharges and recharges automatically. The discharge occurs via the drain

pipe and not via the valve.

Relief valve:

the solenoid pilot also serves as a relief valve (not present on pump), opening in the event

of pressure in excess of 16-19 bars.

Lower pressure:

pressure is lowered by the circuit being discharged for 10 seconds after water or steam

have been dispensed (see variables A and B).

Conﬁguration with dual-sensor valve card (water/steam position Milk Island posi-

tion sensor):

After water has been dispensed - > the solenoid pilot opens to the discharge side as soon as the sensor is

disengaged.

Immediately after steam has been dispensed - > the solenoid pilot opens to the discharge side as soon as

the sensor is disengaged.

Water dispensed after steam has been dispensed -> the solenoid pilot opens to the discharge side as soon

as the sensor is disengaged.

- After each beverage has been dispensed -> the solenoid pilot opens to the discharge side.

- Each time the appliance is switched on and the temperature is reached -> the solenoid pilot opens to the

discharge side.

- When the temperature is reached -> the solenoid pilot opens to the discharge side.

Conﬁguration with three-sensor valve card (water/steam closed position

milk island position sensor):

In addition to the functions described in conﬁguration A, the following also occur:

Each time the closed position central sensor is disengaged -> always open the solenoid pilot towards the

discharge side.
