8. CLEANING THE APPLIANCE
Important!
• Do not use solvents, abrasive detergents or alcohol to clean
the coffee machine.
• Do not use metal objects to remove encrustations or coffee
deposits as they could scratch metal or plastic surfaces.
• Should the machine remain idle for more than a week, it
is advisable to carry out a rinse cycle before preparing any
beverages.
Danger!
• Never immerse the coffee maker in water when cleaning: it
is an electrical appliance.
• Before commencing any cleaning operation on the outside
of the machine, turn it off, unplug it from the mains socket
and wait for it to cool down.

9. CLEANING THE COFFEE MILL
1. Clean the attachment area with the brush (C9) (fig. 27).
2. Use the brush to clean the coffee guide (fig. 28).
Efficient grinding
The burrs are subject to wear over time. As time goes by, to
achieve the perfect quantity, you need to turn the dial (B4)
towards the highest numbers. When you reach a setting of be-
tween 30 and 40, you need to set the extra grinding range (see
section “7. Settings menu” - “Extra grinding range”).
When the quantity of ground coffee becomes less than expect-
ed, contact a service centre to have the burrs replaced. With the
new burrs fitted, adjust the coffee mill by accessing the settings
menu and selecting the first range of the “extra grinding adjust-
ment” setting. Next, turn the ground coffee quantity dial (B4) to
the Min position and set the quantity as for first-time use (see
“La “dose perfetta””).
10. WATER HARDNESS
The descale light (B3) comes on following a predetermined
period of operation that depends on a water hardness setting.
The machine can also be programmed according to the actual
hardness of the local water supply, in which case descaling may
be required less frequently (see section “7. Settings menu”).
1. Remove the "TOTAL HARDNESS TEST" indicator paper (C5)
from its pack.
2. Immerse the paper completely in a glass of water for about
one second (fig. 29).
3. Remove the strip from the water and shake lightly (fig. 30).
