After several lighting attempts, the electronic controller shuts down the boiler.
Pilot burner nozzle dirty - Clean with compressed air
Check the regular gas flow to the boiler and that the air has been eliminated from the pipes.
Make sure the electrodes are correctly positioned and free of any deposits (see fig. 11).
Make sure the boiler is connected to an efficient earthing system.
Check the connections to the ignition and ionisation electrodes.
The electrodes are not discharging in the ignition phase.
Make sure the electrodes are correctly positioned and free of any deposits (see fig. 11).
Check the power supply.
Check the connections to the ignition and ionisation electrodes.
Check the connections to the electronic flame controller.
Make sure PHASE-NEUTRAL are not inverted and that the earth contacts are efficient.

Make sure the gas pressure is sufficient and that the boiler shell is not dirty.
The control thermostat switches on again with too great a temperature difference
Make sure the thermostat bulb is properly inserted in the sheath.
Check the 2-stage control thermostat.
The boiler produces condensation water
Make sure the boiler is not operating at too low temperatures (below 50°C).
Make sure gas consumption is regular.
