3.4 Troubleshooting
Diagnostics
The boiler is equipped with an advanced self-diagnosis system. In case of a boiler fault, the display lights up indicating
the fault code and, in case of cascade connection, the module number.
•
There are faults that cause permanent shutdowns which can be reset by pressing the
OK
button for one second or
with the
RESET
button on the remote timer control (optional) if installed. If the boiler fails to restart after resetting, it
is necessary to eliminate the fault first.
•
Other faults cause temporary shutdowns which are automatically reset as soon as the value returns within the boil-
er's normal working range.

Fault
code
Fault
Possible cause
Cure
01
No burner ignition
No gas
Check the regular gas flow to the boiler and that
the air has been eliminated from the pipes
Ignition/detection electrode fault
Check the wiring of the electrode and that it is
correctly positioned and free of any deposits
Faulty gas valve
Check the gas valve and replace it if necessary
Insufficient gas supply pressure
Check the gas supply pressure
Trap blocked
Check the trap and clean it if necessary
02
Flame present signal
with burner off
Electrode fault
Check the ionization electrode wiring
Card fault
Check the card
03
Overtemperature pro-
tection intervention
No water circulation in the system
Check the circulating pump
Air in the system
Vent the system
04
Fume extraction duct
safety device interven-
tion
Fault F07 generated 3 times in the last 24 hours
See fault F07
05
Fan protection interven-
tion
Fault F15 generated for 1 hour (consecutive)
See fault F15
06
No flame after ignition
phase (6 times in 4
minutes)
Ionization electrode fault
Check the position of the ionization electrode
and replace it if necessary
Flame unstable
Check the burner
Gas valve Offset fault
Check the Offset adjustment at minimum power
air/fume ducts obstructed
Remove the obstruction from the flue, fume
extraction ducts, air inlet and terminals
Trap blocked
Check the trap and clean it if necessary
07
High fume temperature

overtemperature indica-
tion
(Viewable only in His-
tory Menu)
insufficient system water circulation
check water circulation
09
