DIAGNOSTIC CODES
In this generation of PCB it's possible to have more detailed fault signals
compared to the past. This is made to give to the service the chance to know
with an higher level of precision where the problem is, and avoid in this way
loss of time and/or the unnecessary substitution of functioning components.

CODE TYPE MEANING
10 Final End of available attempts: this alarm is generated because the boiler failed the ignition
for the 5 attempts available.
It's necessary to reset the boiler.
Post pump time 30", Post purge time for 5".
Or Condense electrode intervention.
11 Temporary False flame: this alarm is generated because the boiler sensed the flame before the
IGNITION PHASE (spark +gas operators). The boiler stops the ignition and goes in
stand-by mode.
If the situation resets, the boiler will work, otherwise appears on the display the fault
code 15.
12 Temporary Unsuccessful ignition in the second attempt: this alarm is generated from the 2nd
attempt.
If the ignition is successful the boiler will work at the requested thermal load, otherwise, if
the 5th attempt is failed appears on the display the fault code 10.
Condense electrode intervention.
13 Temporary This alarm is generated because there is a problem on the bridge on the wiring harness.
Check the plug J13 between 3&4.
14 Final
15 Final Flame presence without reasons in stand-by: This alarm is generated as the
evolution of error code 11. Check the electrode connections, the ignition transformer, the
wiring harness.
CODE TYPE MEANING
20 Final Limit thermostats: this alarm is generated because the boiler sensed the intervention
of one of the two thermostats described in the section "LIMIT THERMOSTATS" of this
presentation.
It's necessary to reset the boiler.
Post pump time for 30", Post purge time for 5".
21 Temporary NTC FLUE TEMPERATURE probe disconnected.
22 Final Wiring harness: this alarm is generated because there is a problem on the bridge on
the wiring harness.

FAULT CODES
Fault codes take priority over all display functions in the event of a system
fault occurring.
There are TWO different kind of faults (temporary-final) and THREE kind of
signals are displayed, as you can see here under:
Only KEY
CODE
matically (in the meanwhile it will go on working).
If the correct functioning is not reached, we can have two different situations:
1X
(A) the KEY
or (B) KEY
2X
A RESET DURING THIS PHASE WILL HAVE NO EFFECT.
(A) Only RESET
3X
The fault is due to a random situation. If the alarm is repeated in the time, is
4X strongly suggested to call the After Sales Service.
(B) KEY
5X
If alarm 12 code is temporarily displayed at ignition (with flame burn-

persists.
