The machine has been adjusted on a 25
°
òH
value, which causes the warning light to switch
on after 150 l approx.
Should it be necessary, the water hardness value
may be exactly programmed, following the
instructions shown at page 82.
The following adjustments are possible:
Hardness 4:
high water hardness, over 29
°
òH
(14
°
dH), i.e. 80 l water approx.
Hardness 3:
medium water hardness, approx.
20-29
°
òH (7-14
°
dH), approx. 150 l water
passage.
Hardness 2:
soft water, approx. 12-20
°
òH
(4-7
°
dH) approx. 300 l water passage
Hardness 1:
very soft water, less than 10
°
òH
(3
°
dH), approx. 500 l water passage
In hard water regions, a filter should be used both
to improve the coffee quality or to protect the
machine, thus reducing the descaling frequency.
Note:
for this purpose, use a descaling product
suitable for coffee machines.
Never use vinegar!
Descaling can be performed in two ways:
Automatic descaling
Select this mode in the programming menu (see

package). Switch the machine on the programming
mode. Place a large container under the steam/
hot water spout and open slowly the steam knob.
The automatic descaling starts: Small amounts of
descaling solution are pumped into the circuit.
Then the pump stops to let the solution take effect.
During this phase, the following message is
displayed:
