14. DESCALING
Over time, calcium in the water may cause obstructions, reduc-
ing the eciency of the coee maker.
14.1 Descaling the espresso unit
It is recommended to descale the espresso maker when the
descaling notication ashes (the steam button (B3) will
emit a double ashing light) and this will occur with every 200
espressos that are brewed. This notication will not prevent any
function.
The notication could be temporarily postponed by pressing
the espresso side push buttons. At the end of the next brew
cycle, if descaling has not been completed, the notication will
ash on the steam button. We recommend using commercially
available De’Longhi descaler.
Proceed as follows:
1. Fill the tank with the descaler solution (use sample provid-
ed in the package), obtained by diluting the descaler with
water following the instructions on the package.
2. Press the “Espresso ON/OFF” button (g. 12) to turn the
machine on. The integrated light ashes.
3. Make sure the portalter is not attached and position a
bowl under the boiler outlet.
4. Press and hold the steam button (B3) for at least 6 sec.
This will start the automated Descaling Process.
5. The descaling process will take about 30 minutes to be
completed. In the meantime, the descaling button will
blink. While the machine starts dispensing water, open
once steam knob 2-3 seconds to discharge a little water
from the frother system.
6. To eliminate residues of solution and scale, rinse the tank
well, then ll it again with fresh water (without descaler).
7. Press the button (g. 15) and deliver water until the
tank is completely empty.
8. Repeat operations 6 and 7 again.
If descaling is not performed regularly as required. The warran-
ty will be void if the repair is a result of damage to the coee
maker due to limescale.
14.2 Descaling the drip coee unit
It is recommended to descale the coee maker when the desca-
ling notication ashes (the Bold LED button will emit a double
ashing light) and this will occur with every 40 coees that are
brewed. This notication will not prevent any function.
The notication could be temporarily postoned by touching any
touch icon of the drip side.
At the end of the next brew cycle, if descaling has not been com-
pleted, the notication will ash on the BOLD LED.
We recommend using commercially available DeLonghi descal-
er.
1. Remove the antichlorine lter and pour the descaling
product into the tank;
2. Fill the tank with water up to the “max” level for the correct
dilution;
3. Place the carafe on the warming plate;
4. Press and hold the “BOLD” touch icon for at least 6 seconds
to start the “descaling” cycle.
5. The “descaling” cycle will take about 30 minutes. During
the descaling cycle the “BOLD“ led will blink.
6. Rinse at least 3 times by operating the machine with water
only (i.e. as in 7.5, but without coee)
