Bad connection: check the wiring and connectors.
Incorrectly fitted sensor: check that the sensor has been correctly fitted
Faulty sensor: replace the sensor
No flow or insufficient flow:
Check the circulation (direction, pump, valves)
Check the water pressure
Check the cleanliness of the heat exchanger
Maximum flue gas temperature exceeded:
Wait until the flue gas temperature has decreased
(1)

8.2 Lock out
If the blocking conditions still exist after various start attempts, the boiler
goes into lockout (also called error). The boiler will also lock out if an error
is signalled anywhere in the boiler. An error code will appear on the dis­
play. The error code is displayed as follows:
In a red flashing display:
