gered.
Air-break
The machine is locked if after 10 selections the micro-switch
has never signalled the lack of water.
Volumetric counter
Failed computation of the volumetric counter within a maxi-
mum given time.
Boiler
The machine will lock if after the maximum time of heating
from the machine start, or from the last selection, the boiler
fails to reach the operating temperature.
CAN-BUS board
