14. DESCALING
Over time, calcium in the water may cause obstructions, reduc-
ing the eciency of the coee maker.
14.1 Descaling the espresso unit
It is recommended to descale the espresso maker when the
descaling notication ashes (the steam button (B3) will
emit a double ashing light) and this will occur with every 200
espressos that are brewed. This notication will not prevent any
function.
The notication 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 notication will
ash on the steam button. We recommend using commercially
available De’Longhi descaler.
Proceed as follows:
1.
Pour into the tank the descaling product following the in-
structions in the package. Fill the tank with water up to the
“max” level for the correct dilution.
2. The “Espresso ON/OFF” button (g. 12) light should be kept
OFF.
3. Make sure the portalter 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. While the machine starts dispensing water, open once
steam knob 2-3 seconds to discharge a little water from
the frother system.
The clock will switch to a countdown (27 min) during the
process and will revert back after the end of descaling.
The steam button (B3) will blink until the end of descaling.
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.
While the machine starts dispensing water, open once
steam knob 2-3 seconds to discharge a little water from
the frothing system.
8. Repeat operations 6 and 7 again.
If descaling is not performed regularly as required, the warranty
will be void if the repair is a result of damage to the coee maker
due to limescale.
14.2 Descaling the drip coee unit
It is recommended to descale the coee maker when the desca-
ling notication ashes (the Bold LED button will emit a double
ashing light) and this will occur with every 40 coees that are
brewed. This notication will not prevent any function.
The notication 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 notication will ash on the BOLD LED.
We recommend using commercially available DeLonghi descal-
er.
1.
Remove the antichlorine lter and pour into the tank the des-
caling product following the instructions in the package;
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. During the descaling cycle the “BOLD“ led will blink.
The clock will switch to a countdown (27 min) during the
process and will blink until the end of descaling.
6. Rinse at least 3 times by operating the machine with water
only (i.e. as in 7.5, but without coee)
