15. TROUBLESHOOTING SERVICE FAULTS

The faults shown on the display are identified with the symbol "E" and a number (fault code). For a
complete list of faults, see the following table.
If "R" appears on the display the fault must be RESET by the user.
To reset, press and hold down

• Check that the gas valve is open and there is no air in
the gas supply circuit.
• Check the gas supply pressure.
• Check the wire is uninterrupted and makes good
contact with the flame sensing electrode and the
ignition switch.
• Check the connections between the gas valve and the
electronic board.
• Check the flame sensing electrode is in good
condition and in the right position (see the
POSITIONING THE IGNITION AND FLAME-
SENSING ELECTRODE section).
• Check pump operation (unscrew the front cap and
release the pump impeller with a screwdriver).
• Check the pump power input wiring.
• Check that the limit thermostat is undamaged and
replace it if necessary.
• Check the continuity of the limit thermostat wiring.
• Check the CH flow NTC probe (*).
• Check whether the exchanger is clogged.
• Set parameter F43 with the value indicated in the
table in the SETTING PARAMETERS section.
• See the actions indicated in E01.
• See the actions indicated in E42.
• Check the CH flow NTC probe (*).
• Check the continuity of the CH flow probe wiring.
• Make sure the wiring has not shorted.
• Check the DHW NTC probe (*).
• Check the continuity of the DHW probe wiring
• Make sure the wiring has not shorted.
• Check the fumes NTC probe (**).
• Check the continuity of the fumes probe wiring
• Check the continuity of the earth connections between
the electronic board (X4 connector) and the power
supply terminal block.
• Replace the electronic board.
• If the pressure in the CH circuit is < 0.5 bar, perform
filling (see the FILLING THE SYSTEM section).
• Check the hydraulic pressure switch works correctly.
• Check the continuity of the hydraulic pressure switch
wiring
• Check whether the power supply reductions are due
to reasons other than the boiler. If so, contact the
electricity provider.
