Questions and answers
Fallo A1 en caldera
Error A01 on the Ferroli ECONCEPT TECH 25 A boiler indicates that the burner fails to light. Possible causes include no gas supply, an ignition/detection electrode fault, a faulty gas valve, insufficient gas supply pressure, or a clogged trap. To resolve this, check the gas flow, ensure the air is removed from the pipes, inspect the electrode wiring and cleanliness, verify the gas valve function, check the gas supply pressure, and clean the trap if necessary. Press the RESET button for 1 second to restore operation after addressing the issue.
