IBERITAL
NOTE: If the machine has a display, follow the indications as they appear on the screen (see the section on display
operation).
2.3.2. Programming the electronic pre-brew (not available on all models)
The control unit has a function called 'pre-brew'. Pre-brew can be enabled or disabled. If your machine has a visual
display, it will be possible to carry out this action via an option on the display. If it does not have a display, the
function is performed in the following manner:
To enable pre-brew, switch off the machine's main switch and press the button 1 espresso, 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 coff ee, keep it pressed
and set the main switch to position 1 or 2, either will do, and the 1 coff ee 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 fi lling with water.
If the level sensor is not covered with water within one minute, the control unit safety control will stop the water
fi lling process and the motor.
The signal for the control unit alarm is the fi ve LEDs fl ashing simultaneously.
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 fi lling from being sent.
Warning: This alarm signal is always activated during the fi lling process when this immediately follows machine
installation. This is due to the fact that it takes more than 1 minute to fi ll the boiler. When this happens, set the switch
to zero and return it to the fi lling position in order to continue fi lling the boiler.
B. NO IMPULSES FROM THE FLOW METER (5 seconds)
If during feed there are no impulses from the fl ow meter, the control unit will detect it and the LED for the selection
being dispensed at that moment will light up and fl ash, but dispensing will not stop.
This alarm signal is produced due to a bypass of the signal from the fl ow 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 coff ee feed time is over 2 minutes, the control unit detects an excess in the normal coff ee feed time.
Coff ee feed will be stopped automatically and the LED for the chosen selection will remain fl ashing.
