E20
C
YES
-Flag (flame failure after 3 ignition attempts) caused by:
-problems on the gas supply network: lack of gas; low gas
pressure in the network; gas meter / defective network regulators;
presence of condensate (water) in the combustion gas;
-problems to the elements of the internal combustion circuit of
the boiler: connections / electrodes / ignition transformer / plate;
Specific condensation boilers: problems on the condensate
drain.
Manual reset from RESET button

C
YES
-defence in the flame detection phase, invalid ionization current
signal.
Manual reset from RESET button
E23
C
YES
- the current ionization outside the combustion cycle.
Manual reset from RESET button
E25
C
YES
-supply voltage variation / interruptions / gaps / variations of
frequency / higher / lower frequency variations than standard
ones may lead to permanent blocking in the E25 error,
depending on the state of boiler.
