DESCALING
Descaling must be carried out at the latest when this
message is displayed. In spite of the message, the
machine does not stop working.
Furthermore, said display warning may be adjusted
according to the water hardness degree. The ma-
chine has been adjusted at the factory to 25
°
fH
value, which causes the display to switch on showing
the message descaling after approx 150 l.
The water hardness value may be changed, if
necessary, following the instructions shown on page
37.
The following adjustments are possible:
Hardness 4: high water hardness, over 29
°
fH (14
°
dH), approx. 80 l water passage.
Hardness 3:
medium water hardness, approx. 20
°
-
29
°
fH (7
°
-14
°
dH), approx. 150 l water passage
Hardness 2:
soft water, approx. 12
°
-20
°
fH (4
°
-7
°
dH), approx. 300 l water passage
Hardness 1:
less than 10
°
fH (3
°
dH), approx. 500
l water passage
In case of hard water, a filter should be used both to
improve the coffee quality and to protect the ma-
chine, thus reducing the descaling frequency.
Note:
for this purpose, use a descaling product
suitable for coffee machines. Never use vinegar to
clean the machine; it might damage it.
There are two ways to carry out the descaling of the
machine:
Automatic descaling
Set the machine on the programming mode (see
page 3ç).
Move the asterisk to the menu item Descaling using
the keys
and press MENU to activate it.
The display shows:
"DESCALING "
Pour a descaling solution into the water tank (accord-
ing to the instructions on the package). Place a large
container under the steam/hot water dispensing
tube and open the steam/hot water knob slowly. The
automatic descaling starts. Small quantities of
descaling solution are pumped into the circuit. Then
the pump stops to let the solution take effect.
The display shows:
"MACHINE IS "
"DESCALING "
This operation takes about 45 minutes. As soon as
descaling is completed, the display shows:
"DECALING "
"FINISHED "
and the pump stops.
Turn the hot water off. Press the
MENU' key. The
display shows that the machine needs to be rinsed to
clean any descaling remains.
"RINSE MACHINE "
"FILL WATERTANK "
Remove the water tank, rinse it and fill it with water.
Clean the machine using the hot water knob and let
the whole tank content flow out. The display shows:
"RINSING "
"FINISHED "
Turn the hot water off. Press the MENU' key. The
machine is now in the programming mode. Press the
ESC key. The machine is now in the normal mode.
After being heated, the machine will be ready for
coffee dispensing.
N.B. The descaling process can be interrupted at
any time using the MENU' key. Before that, how-
ever, turn the hot water valve off.
Standard descaling
Switch off the machine. Pour a descaling pro-
duct into the water tank (according to the instructions
