9. Place an empty 67.62 fl oz / 2 l container under the spouts
(fig. 41). Press "Next" to start descaling ("Back" to go back
to the previous screen or "X" to exit the procedure, remem-
bering to remove the descaling solution from the tank)
Important! Danger of scalding
Hot water containing acid flows out of the spouts. Take care to
avoid contact with splashes of this solution.
10. IThe 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;
After about 40 minutes, the descaling action ceases;
11. The appliance is now ready to be rinsed through with clean
water. Empty the container used to collect the descaler
solution. Remove the water tank, empty, rinse under run-
ning water, fill with fresh water up to the MAX level and
put back in the appliance (fig. 42). Press "Next";
12. Place the container used to collect the descaler solution
empty under the spouts and press "Next" to start rinsing;
13. Hot water is delivered from both the hot water spout and
coffee spouts;
14. When the water in the tank has run out, empty the con-
tainer used to collect the rinsing water;
15. Extract the water tank and put back the water softener fil-
ter if removed previously. Press "Next" to continue;
16. Fill the tank with fresh water up to the MAX level, put back
in the appliance and press "Next" to continue;
17. Place the container used to collect the descaler solution
empty under the spouts and press "Next" to start another
rinsing cycle;
18. When the water in the tank has run out, empty the con-
tainer used to collect the rinsing water, remove and empty
the drip tray (A15) and grounds container (A10), then put

20. The descaling process is now complete". Press "OK". The ap-
pliance performs a rapid preheat cycle and then goes back
to the homepage.
Please note:
• If the descaling cycle is not completed correctly (e.g. elec-
trical power failure) it is advisable to repeat the procedure;
• After descaling, it is normal for the grounds container
(A10) to contain water.
• If the water tank has not been filled to the MAX level after
descaling, the appliance prompts for a third rinse to ensure
that the descaler solution has been completely eliminated
from the machine's internal circuits. Before starting rins-
ing, remember to empty the drip tray.

18. SETTING WATER HARDNESS

The descaling alarm is displayed after a period of time established
according to water hardness. The machine 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" indicator paper (D1) from
its pack (attached to the Quick Guide).
2. Immerse the paper 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 appear, depending
on the hardness of the water. Each square corresponds to
1 level.
18.2 Setting water hardness
1. Press the settings menu icon (C3) on the homepage (C);
2. Scroll the pages and select "Water hardness";
3. Press "Set";
4. Carry out the procedure described in the previous section
and measure water hardness;
5. Press the dot corresponding to the water hardness meas-
ured previously as indicated in the following table:
