Warnings: in case of interruption of the washing
by turning off the machine (manual or acciden-
tal), an alarm message will be displayed at the
first start. It is very important that a complete rins-
ing of the group head is carried out to remove
any residual detergent product from the coffee
circuit.

ing, tank washing, etc.).
To change the value, access the maintenance
screen from the settings menu.
To achieve this:
