Working to reset
Press the RESET key for 5 seconds: The status signals will flash red quickly and the boiler will start its reset proce-
dure.If the error code continues to display, search for the cause in the error table and apply the solution.

Circulation
Check the wiring.
Check that the sensors are operating correctly
Check that the sensor has been correctly fitted
Vent the air in the heating system
Check the water pressure
Check the cleanliness of the heat exchanger
Check the circulation (direction, pump, valves)
Replace the sensor if necessary

Check that the gas valve is fully opened
Check the supply pressure
Purge the gas supply to remove air
Check the operation and setting of the gas valve unit
Check that the air inlet and flue gas discharge flues are not blocked
Replace the ionization/ignition electrode
No ignition
Ignition arc, but no
flame formation
Presence of the flame
but insufficient
ionization (<1μA)
External draught over
the boiler
Defective gas/air unit
Check for adequate draw on the chimney connection
Replace the gas/air unit
Bad connection
Safety parameters not
found
Check the wiring
Several possible
causes
The fault codes can be read with a suitable controller or the service
tool
