SERVICE FUNCTIONS

If enabled in the programming menu, some operations

Enter the relative password to:

- dispense several selections consecutively to fill in a jug

(jug facilities);

system only)

- lock-unlock the keyboard.

If the keyboard lock is active, the “INTERRUPTED

ging the mixer.

- cappuccinatore wash (models with cappuccinatore

only)

the cappuccinatore shall be washed whenever the milk

dispensing cycle is interrupted (for a period of time)

and/or at least every day.
