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
boiler's normal working range.

Cure
Check the regular gas flow to the boiler and that
the air has been eliminated from the pipes
Check the wiring of the electrode and that it is
correctly positioned and free of any deposits
Check the gas valve and replace it if necessary
Check the gas supply pressure
Check the trap and clean it if necessary
Check the ionization electrode wiring
Check the card
Check the circulating pump
Vent the system
See fault 07
See fault 15
Check the position of the ionization electrode and
replace it if necessary
Check the burner
Check the Offset adjustment at minimum power
Remove the obstruction from the flue, fume
extraction ducts, air inlet and terminals
Check the trap and clean it if necessary
Clean the exchanger
Check the integrity of exchanger
Check the fume sensor or replace it
check water circulation
check water circulation
Check the wiring or replace the sensor
