The machine must be rinsed so as to eliminate the residues of descaling
solution from inside the machine. Proceed as follows:
•
remove the water tank, rinse it and fill it with clean water.
•
reposition the tank.
•
empty the collection container (located under the milk frother) that is
full of liquid, and then replace it under the milk frother.

the descaling program finishes after an hour and the machine is ready
to make coffee again.

be started again from the beginning.
IMPORTANT: THE GUARANTEE IS NOT VALID IF THE ABOVE
DESCALING OPERATION IS NOT PERFORMED REGULARLY.
10.4 SETTING THE WATER HARDNESS
The
light (chap. 12 - point 5) switches on after a preset period of operation,
set in the factory, considering the maximum quantity of lime scale that may be
contained in the mains water. If necessary, this period of operation can be exten-
ded, thus making the descaling operation less frequent, by programming the machi-
ne based on the actual lime content in the water used. Proceed as follows:
•
after having removed the "Total hardness test" strip (enclosed on page 2)
from its packaging, dip it fully in the water for a few seconds, then pull it out
and wait around 30 seconds (until it changes colour and a number of red
dots are formed);
•
check that the machine is off (all the indicator lights are off);
•
press the
button (Fig. 14) and hold it for at least 5 seconds. The four
