10. CLEANING THE COFFEE MILL
1. Clean the attachment area with the brush (C9) (g. 29).
2. Use the brush to clean the coee guide (g. 30).
Ecient 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 “8. Menù impostazioni” - “Range di macinatura extra”).
When the quantity of ground coee becomes less than expect-
ed, contact a service centre to have the burrs replaced. With the
new burrs tted, adjust the coee mill by accessing the settings
menu and selecting the rst range of the “extra grinding adjust-
ment” setting. Next, turn the ground coee quantity dial (B4) to
the Min position and set the quantity as for rst-time use (see
“La “dose perfetta””).
11. WATER HARDNESS
The descale indicator
(B3) lights up following a prede-
termined period of operation that depends on the hardness
of the water. 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 “8. Menù
impostazioni”).
1. Remove the "TOTAL HARDNESS TEST" indicator strip (C5)
from its pack.
2. Immerse the strip completely in a glass of water for about
one second (g. 31).
3. Remove the strip from the water and shake lightly (g. 32).

ONLY
Softballs (C7) are an innovative treatment system able to pro-
long the life of the machine, without altering the properties
of the water, while ensuring consistently creamy and aromatic
coee. To optimize the eectiveness of the treatment, leave
Softballs in water overnight before use.

13. DESCALING
Important!
• Before using the descaler, (C6)read the instructions and the
labelling on the pack.
• Use De’Longhi descaler only. Using unsuitable descaler
and/or performing descaling incorrectly may result in
faults not covered by the manufacturer’s guarantee.
• Descaler can cause damage to delicate surfaces. If the prod-
uct is accidentally spilt, dry immediately.
