What does the fault code A09 mean in Cointra?

Gas valve anomaly The gas valve may be faulty or have interrupted actuator/wiring, preventing its opening or modulation; check the continuity of the wiring and power supply to the actuator and ensure that the valve opens on demand.

What does fault code A16 mean in Cointra?

Gas valve anomaly Fault in the valve or its actuator/wiring; check continuity of the modulating actuator and presence of control signal from the PCB, replacing the valve if it does not operate correctly.

What does the F50 code mean in Cointra?

Gas valve anomaly Modulating actuator error (interrupted wiring) or faulty valve; check actuator/coil continuity and control voltage, and replace the valve if it does not respond.

What does fault code A62 mean in Cointra?

There is no communication between the control board and the gas valve. The valve may be faulty or not responding to the control board's signal; check connectors and wiring between the PCB and the valve, presence of control signal, and replace the valve if it does not communicate.

Fault codes related to this part (not the entire boiler). They usually have more possible causes: first rule out electrodes, wiring/connections, and gas supply. Verified with ≥3 sources.

Code	What does it mean?	Cause and diagnosis (this part)
A09	Gas valve anomaly	The gas valve may be faulty or have interrupted actuator/wiring, preventing its opening or modulation; check the continuity of the wiring and power supply to the actuator and ensure that the valve opens on demand.
A16	Gas valve anomaly	Fault in the valve or its actuator/wiring; check continuity of the modulating actuator and presence of control signal from the PCB, replacing the valve if it does not operate correctly.
F50	Gas valve anomaly	Modulating actuator error (wiring interrupted) or faulty valve; check continuity of the actuator/coil and control voltage, and replace the valve if it does not respond.
A62	There is no communication between the control board and the gas valve.	The valve may be faulty or not responding to the signal from the control board; check connectors and wiring between the PCB and the valve, presence of control signal, and replace the valve if it does not communicate.
