4. Place an empty container with a minimum capacity of 1.8
litres under the hot water spout (C6) and coffee spouts (A9)
(fig. 34); Press OK (B15);
Important! Danger of scalding
Hot water containing acid flows out of the coffee spouts and
hot water spout. Take care to avoid contact with splashes of this
solution.
5. The descale programme starts and the descaler liquid
comes out of the hot water and coffee spouts. A series of
rinses is performed automatically to remove all the scale
residues inside the coffee machine. This is the longest
phase and may account for more than half the total des-
caling time.
After completing the descaling cycle, the appliance is ready to
be rinsed through with clean water.
6. Empty the container used to collect the descaler solution.
Remove the water tank from the machine, empty it and
rinse under running water, then fill with clean water up
to the MAX level (fig 35) and reposition it in the machine.
7. Empty the container used to collect the descaler solution,
then position it under the coffee spout and the hot water
spout (fig. 34);
8. Press OK (B15);
9. Hot water is delivered first from the coffee spouts, then
from the hot water spout;

10. When the water in the tank has run out, empty the con-
tainer used to collect the rinsing water;
11. Take out the water tank and fill with fresh water up to the
MAX level.
12. If the water softener filter was removed, replace it in its
housing in the water tank, and reposition the tank in the
appliance;
13. Empty the container used to collect the descaler solution,
then position it under the hot water spout.
14. Press OK (B15).
15. Hot water comes out of the hot water spout;
16. At the end of the second rinse, remove, empty and replace
the drip tray (A15) and grounds container (A11).
17. Empty the container used to collect the rinse water; re-
move the water tank from the machine, empty it and rinse
under running water, then fill with clean water up to the
MAX level and reposition it in the machine.
The descaling cycle is now complete.
Please note!
• If the descaling cycle is not completed correctly (e.g. power
failure or disconnection from power supply), the machine
will prompt it to be completed when switched on again.
• WATER may find its way into the grounds container (A11)
during the descaling cycle: this is quite normal;
• If the water tank has not been filled to the MAX level, at
the end of descaling, the appliance requests a third rinse to
guarantee that the descaler solution has been completely
eliminated from the machine's internal circuits.
• The appliance may request descaling cycles at very short
intervals. This is normal and due to the appliance's ad-
vanced control system.
• THE descaling procedure can also be started by pressing
and holding the icon (B8).
18. SETTING WATER HARDNESS
The descaling alert is displayed after a period of time estab-
lished according to water hardness.
The machine is set by default for a hardness level of 4. The ma-
chine can also be programmed according to the actual hardness
of the local water supply, so that the descaling procedure will be
required less frequently.
18.1 Measuring water hardness
1. Remove the "TOTAL HARDNESS TEST" reagent strip (C1)
from its pack;
2. Immerse the strip completely in a glass of water for about
one second;
3. Remove the strip from the water and shake lightly. After
about a minute, 1, 2, 3, or 4 red squares will appear, de-
