water pressure in the boiler, expressed in atmosphere, time and date.
Note: The water temperature can be displayed by pressing MODE key: the display shows temperature,
expressed in Celsius degrees:
• To return to the operational message, press MODE.
PRESS MODE TO GO OUT OF PROGRAMMING MODE.

7. TROUBLESHOOTING AND SOLUTIONS
CAUSES
• Group is blocked: In continuous delivery, if delivery is
not stopped manually using the STOP key within the time
limit of 120 sec.
• Should the turbine operate irregularly, the fault will be
signalled by the blinking of the block red LED on the
push-button pad of the group involved in the fault.
In this case delivery is not dosed, but if the operator does
not intervene manually with the STOP key, blocking oc-
curs when the time limit is reached.
• If the water level control solenoid valve remains open
for more than 90 sec., it is automatically switched off and
the fault is signalled by the block red LED blinking on all
the push-button pads.
• The water mains tap or the softener taps are shut.
• The water entry union filter is obstructed.
• The jet is obstructed
• The injector is obstructed
• (Only for versions with electronic dosing) the flowmeter
connection is obstructed.
• The solenoid valve will not open:
• The coil is not getting power.
• The coil is broken.
• The core is blocked.
• Air bleeding of the boiler did not occur during the water
heating stage.
• The water heating circuit is partially obstructed (except
lever machine).
• The heating element is broken.
• The heating element is not receiving power.
• The safety thermostat, pressure switch and main switch
are faulty.
• The level sensor/control centre electrical connection is
broken.
• The frame earthing/control centre electrical connection
