FAULT POSSIBLE REASON SERVICE ACTION
E25 No water safety trip. • No water in the CH circuit
(pump blocked or exchanger
obstructed).
• CH flow NTC probe faulty.
• Electronic board faulty.
• Check pump operation (unscrew the front cap and
release the rotor with a screwdriver).
• Check the pump power input wiring.
• Check the CH flow NTC probe (*).
• Check whether the exchanger is clogged.
E26 CH delivery NTC probe
overheating safety trip.
• See the reasons indicated in E25. • See the actions indicated in E25.
E35 Parasite flame (flame
error).
• The electronic board is not
earthed.
• Flame sensing electrode faulty or
incorrectly positioned.
• Electronic board faulty.
• Check the continuity of the earth connections between
the electronic board (X4 connector) and the power
supply terminal block.
• Check the flame sensing electrode is in good
condition and correctly positioned (see the
POSITIONING THE IGNITION AND FLAME-
SENSING ELECTRODE section).
E36 Fumes NTC probe fault. • Fumes NTC probe faulty
(shorted).
• Fumes probe wiring shorted.
• Check the fumes NTC probe (**).
• Make sure the fumes probe wiring has not shorted.
E40 - E41 Shutdown due to probable
obstruction of air-flue duct
or insufficient gas inlet
pressure.
• No inlet gas pressure.
• Gas valve modulator wires not
connected.
• Flame sensing electrode faulty or
incorrectly positioned.
• Fumes NTC probe faulty or
incorrectly positioned
• Air-flue duct obstructed.
• Gas valve faulty.
• Electronic board faulty.
• Check the gas supply pressure (for natural gas
Palim.>9mbar).
• Check the connection of the gas valve modulator
wiring to the electronic board.
• Check that the pressure at the burner has been
correctly calibrated (see the GAS VALVE section).
• Check the flame sensing electrode is in good
condition and correctly positioned (see the
POSITIONING THE IGNITION AND FLAME-
SENSING ELECTRODE section).
• Check the fumes NTC probe (**).
• Make sure the air and flue ducts are not obstructed
and have been correctly installed (they must not
exceed the prescribed maximum lengths and must
be fitted with the correct diaphragm – see the
INSTALLING THE DUCTS section).
E42 No flame. • Fan not working (fault or no
power).
• Air-flue duct completely
obstructed.
• Electronic board faulty.
• Check that the fan power supply wiring is connected
to the electronic board.
• Make sure the air and flue ducts are not obstructed
and have been correctly installed (they must not
exceed the prescribed maximum lengths and must
be fitted with the correct diaphragm – see the
INSTALLING THE DUCTS section).
E43 Shutdown due to probable
obstruction of air-flue duct
or insufficient gas inlet
pressure.
• See the causes indicated in E40
- E41
• Input voltage V<180V
(automatically resets at V>185V
or by pressing “R”).
• Electronic board faulty.
• See the actions indicated in E40 - E41.
• Check whether the power supply reductions are due
to reasons other than the boiler. If so, contact the
electricity provider
E50 Shutdown due to fumes
NTC probe tripping for
overheating.
• Fumes temperature>180°C.
• Insufficient heat exchange on the
water/fumes exchanger.
• Fumes NTC probe faulty.
• Electronic board faulty.
• Check the heat exchange of the water/ fumes
exchanger: insufficient circulation or presence of
scale.
• Check the fumes NTC probe (**).
E55 Gas valve not
electronically calibrated
• The electronic board has not
been replaced and the gas valve
has not yet been electronically
calibrated.
• Electronically calibrate the gas valve (parameters F45
and F48) as described in the GAS VALVE section
E62
Safety shutdown if the
flame signal or fumes
temperature fail to
stabilise
• Flame sensing electrode faulty or
incorrectly positioned.
• Fumes NTC probe faulty.
• Electronic board faulty.
• Check the wire is uninterrupted and makes good
contact with the flame sensing electrode and the
ignition switch.
• Check the flame sensing electrode is in good
condition and correctly positioned (see the
POSITIONING THE IGNITION AND FLAME-
SENSING ELECTRODE section).
• Check the fumes NTC probe (**).
E65 Safety shutdown if the air-
flue duct obstruction test
fails frequently.
• See the causes indicated in E40
- E41.
• See the actions indicated in E40 - E41.
