Alarms

As well as recording the pro-
gramming of all the above de-
scribed functions, the electronic
board of this espresso machines
also controls their proper exe-
cution.
The incorrect execution of any
of these functions triggers an
alarm, showed on the display

and machine gives out 3 beeps.
To cancel the alarm, turn the
main switch of machine off and
back on. This alarm could be
triggered due to strong spikes
in the power supply. In case of
memory loss, machine will ope-
rate with factory (default) para-
meters.

and 9 turn on and machine gives
out a continuous beep. To cancel
the alarm turn the main switch

of load from the safety transfor-
mer, therefore all solenoid val-
ves stop operating.
