To enable pre-brew, switch off the machine's main switch and press the button 1 espresso on the left button pad
(group 1), keep it pressed and set the main switch to position 1 or 2, either will do, and the 1 espresso LED will
light up.
Release the button and set the switch to zero (OFF) and then set it in the working position (position 2).
To disable pre-brew, set the machine's main switch to zero (OFF) and press the button 1 coffee, keep it pressed
and set the main switch to position 1 or 2, either will do, and the 1 coffee LED will light up.
Release the button and set the switch to zero (OFF) and then to position 2.
2.3.3. Alarm signals
A. EXCESS BOILER WATER FILLING TIME
The control unit has a waiting time for when the boiler is filling with water.
If the level sensor is not covered with water within one minute (two minutes Expression Pro), the control unit
safety control will stop the water filling process and the motor.
The signal for the control unit alarm is the five LEDs flashing simultaneously. (In all groups).
This alarm signal could be caused by a lack of mains water supply to the machine, an obstruction of the water inlet
or a problem with the control unit that is preventing the signal for automatic water filling from being sent.
Warning: This alarm signal is always activated during the filling process when this immediately follows machine
installation. This is due to the fact that it takes more than 1 minute to fill the boiler. When this happens, set the switch
to zero and return it to the filling position in order to continue filling the boiler.
B. NO IMPULSES FROM THE FLOW METER (5 seconds)
If during feed there are no impulses from the flow meter, the control unit will detect it and the LED for the selection
being dispensed at that moment will light up and flash, but dispensing will not stop.
This alarm signal is produced due to a bypass of the signal from the flow meter cover, or due to a poor connection,
or lastly due to some internal problem in the control unit. If this occurs contact the after-sales service.
C. EXCESS FEED FROM THE FLOW METER
If the coffee feed time is over 2 minutes (3 minutes Expression Pro), the control unit detects an excess in the
normal coffee feed time.
Coffee feed will be stopped automatically and the LED for the chosen selection will remain flashing.
This alarm signal is either due to an obstruction to the flow of water, and the control unit receives slower and more
drawn out impulses than during the normal feed time, or because the coffee is ground very finely or packed in the
filter too tightly, causing excess weight, thus preventing the water from flowing with suitable fluidity.
D. DEPOSIT LEVEL INDICATORS (only portables machines)
This machine has a system for indicating both minimum and maximum levels, which works as follows:
Minimum Level – When the water tank reaches its minimum level, the control unit cuts the current to the
button pad and the heating element, in order to prevent damage to both the element and the pump due to a
lack of water. At that moment the LEDs on the button pad will begin to flash, advising the user that the deposit
must be filled.
When we begin to fill the deposit manually and the water covers the minimum level sensor, the LEDs will turn off
