ALARM CONTROL
The electronic system of this espresso machine manages all machine functions and controls their
correct execution.
In case of anomalies, an alarm is recorded and/or displayed.
An alarm can be triggered also by an improper use of the espresso machine. In this case, it will
be sufficient to correct the improper use.
Some alarms are non-influential for the proper functioning of the machine and, more importantly,
for the user's safety. These alarms are not stored in the system memory. These alarms will be
marked with “A”.
Other alarms are displayed and recorded with their triggering date and time. They can block the
anomalously functioning part. These alarms will be marked with “ABP”.
Finally, there are a few alarms that totally block the machine and are marked as “ABT”.
