• You should use De’Longhi descaler only. Using unsuitable
descaler and/or performing descaling incorrectly may re-
sult in faults not covered by the manufacturer’s guarantee.
1. Turn the appliance on and wait until it is ready for use.
2. Empty the drip tray (A17) and grounds container (A13) and
put both back in the machine.
3. Empty the water tank (A9) completely and remove the
water softener filter (C4), if present.
4. Pour the descaler (C3) into the tank up to level
A
(corre-
sponding to a 100 ml pack) marked on the back of the tank,
then add a litre of water up to level
B
(fig. 32) and put the
water tank back in the appliance.

. Place a container with a
minimum capacity of 1.8
litres under the cappucci-
no maker (A18) and cof-
fee spouts (A12) (fig. 36).
6. Wait for the coffee lights
to come on steadily.
7.
Press and hold the
button (B5) for
at least 5 seconds to con-
firm that you have added
the solution and begin
the descaling procedure. The light in the button comes
on steadily to indicate that the descaling programme has
begun.
8. The
light flashes to indicate the hot water/steam dial
(A19) must be turned to the
I
position.
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.
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 and coffee spouts. A series of rinses
and pauses are performed automatically to remove all the
scale residues inside the coffee machine.
After about 25 minutes, descaling stops and the
and
lights flash on the control panel. Turn the hot water/steam dial
to the
0
position.
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: the
light flashes.
11. Place the container used to collect the descaler solution
empty under the cappuccino maker and coffee spouts (fig.
36).
12. Turn the hot water/steam dial to the
I
position to begin
rinsing. Hot water is delivered first from the cappuccino
maker, to continue and end with the coffee spouts.
13. When the water tank is completely empty, the
and
lights flash on the control panel. Turn the hot water/
steam dial to the
0
position.
14. Empty the container used to collect the rinsing water. Re-
move the water tank, replace the water softener filter (if
removed previously), fill the tank up to the MAX level with
cold water and insert in the appliance. The
steam
light flashes.
15. Place the container used to collect the rinsing water empty
under the cappuccino maker;
16. Turn the hot water/steam dial to the
I
position. Rinsing
continues from the cappuccino maker only.
17. When it finishes, the
steam light flashes on the con-
trol panel. Turn the hot water/steam dial to the
0
position.
18. Top up the water tank with fresh water to the MAX level
and put back in the machine.
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
(A13) to contain water.
16. SETTING WATER HARDNESS
Descaling is necessary after a period of operation established
according to the water hardness set.
The machine is set by default for a hardness value 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.
16.1 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
one level.
