Press both buttons over three to ten seconds.
After the descaling operation has been requested
by pressing the two buttons simultaneously, the
operation CANNOT be cancelled any more and
the descaling cycle will have to be performed to
the end.
The machine will start the warming phase:
ESPRESSO orange light;
ESPRESSO LUNGO white light;
Both buttons will blink (0.5 sec. ON / OFF) until the
warming process is over.
Once the warming process is over, the ESPRESSO
button with a steady orange light will be the
only one available to start the descaling operation.
If no operation is carried out, the machine will be set to
the stand-by mode after nine minutes; moreover, you
will have to repeat the sequence to get access to the
descaling process.

Press the ESPRESSO
ling cycle.
Pressing the button over a long time will have no ef-
fects on the machine.
The descaling procedure involves supplying 2 oz (60 ml)
of solution alternating with a fifteen seconds' pause, until
the tank is emptied.
During the descaling process, the ESPRESSO
button will blink to an orange light (1 sec. ON / OFF).
Once the descaling process has been activated, it
cannot be interrupted until when the machines deliv-
ers the full quantity of descaling solution and water
needed for rinsing.
This means that, if the machine is set to the stand-by
mode owing to a power cut-off, the process will be
resumed from the point where it has been interrupted.
The sequence will be repeated until the "tank empty"
condition is achieved (approximately 15.5 oz/500 ml,
equal to six supply instances).
