Alarms
Besides managing all machine
functions, the electronic system
of this espresso machine con-
trols their proper execution. In
case of anomalies, an alarm is
recorded and displayed.
WARNING
The incorrect use of the machi-
ne can also generate an alarm.
In this case it is sufficient to
correct improper use.
Some of the alarms are non-
influential for the proper func-
tioning of the machine. These
alarms are only displayed and
not stored in the system memory.
This type of alarms is marked as
"A". Other alarms, indicating ano-
malies regarding safety or correct
functioning of machine parts, are
displayed and recorded with their
triggering date and time. They
can block the anomalously func-
tioning part and are marked as
"ABP". Only some alarms totally
block the machine functioning
and are marked as "ABT".
