8.2 Cleaning the tray and the cup support grill
The lower cup support grill 5 must be kept clean at all times; during the normal use of the machine, it is suffi-
cient to clean it with a sponge or a moist cloth. At the end of the working day, clean the tray and the grill also
in the internal areas using warm water and neutral detergent.
8.3 Cleaning the steam spout
Clean the steam spout with a sponge or a moist cloth at the end of the working day to remove all traces of milk or other
substances that inevitably form during the normal operation of the machine. Open the steam tap, placing the spout in
the tub, to remove any residues which may have accumulated in the spout.
8.4 Substitution of boiler water
To change the water inside the boiler, proceed as follows:
1) Cut off the power supply to the machine by turning the main switch
1 to position 0 (zero).
2) Remove the tub and the cup support grille and open the boiler drain tap.
3) Open a steam drawing valve to facilitate the draining of the water until the end of the operation.
4) When water no longer comes out of the boiler, close the boiler drain and the steam drawing tap.
5) Charge the machine with water following the instructions of paragraph “Charging the water in the boi-
ler”.
