Setting Water Hardness; Measuring Water Hardness - DeLonghi ECAM35X.15 Series Instructions For Use Manual

5. Pour the descaler (C3) into the tank up to level A (corre-
sponding to a 100ml pack) marked on the inner surface of
the tank, then add a litre of water up to level B (fig. 24) and
put the water tank back in the appliance;
6. Place a container with a minimum capacity of 1.8 litres
under the cappuccino maker (A20) and coffee spouts (A19)
(fig. 25);
Important! Danger of burns
Hot water containing acid flows from the cappuccino maker and
coffee spouts. Take care to avoid contact with splashes of this
solution.
7. Press the OK icon to confirm that you have added
the descaler solution. The descaling procedure begins;
8. After a few minutes, the

9. When the dial has been turned to the l position, the des-
cale programme starts and the descaler liquid comes out
of the cappuccino maker. A series of rinses and pauses are
performed automatically to remove all the scale residues
inside the coffee machine;
After about 35 minutes, the appliance interrupts descaling and
the light (B3) flashes.
10. The appliance is now ready for rinsing through with clean
water. Empty the container used to collect the descaler
solution. Extract the water tank, empty, rinse under run-
ning water, fill with fresh water up to the MAX level and
put back in the appliance;
11. Place the container used to collect the descaler solution
empty under the coffee spouts and cappuccino maker (fig.
25);
12. Press the OK icon:

15. The appliance is now ready for a second rinse with clean
water. Empty the container used to collect the rinse water.
Extract the water tank, empty, rinse under running water,
fill with fresh water up to the MAX level, replace the water
softener filter (if previously removed) and put back in the

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
(A11) 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 completely
eliminated from the machine's internal circuits.

20. SETTING WATER HARDNESS

The light (B5) comes on 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 mquaachine
needs to be descaled less often.

20.1 Measuring water hardness

1. Remove the "TOTAL HARDNESS TEST" indicator paper (C1)
from its pack (attached to the English instructions);
2. Immerse the paper completely in a glass of water for one
second;
3. Remove the paper from the water and shake lightly. After
about a minute, 1, 2, 3, or 4 red squares form, depending
on the hardness of the water. Each square corresponds to 1
light
level;
