23. "Fill tank": empty the container used to collect the rinse
water, remove the water tank and fill with fresh water up
to the MAX level, then put back in the appliance.
Descaling is complete.
Please note!
• If the descaling cycle is not completed correctly (e.g. no
electricity) we recommend repeating the cycle;
• After descaling, it is normal for the grounds container
(A20) to contain water;
• 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 complete-
ly eliminated from the machine's internal circuits. Before
starting rinsing, remember to empty the drip tray.
• The appliance may request descaling cycles at very short
intervals. This is normal and due to the appliance's ad-
vanced control system.

16. SETTING WATER HARDNESS

The descaling request is displayed after a period of time
established 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 hardness of the
mains water in the various regions so that the machine needs to
be descaled less often.

from its pack (attached to the English instructions);
2. Immerse the paper completely in a glass of water for one

about a minute, 1, 2, 3, or 4 red squares form, depending
