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.

CodeWhat does it mean?Cause and diagnosis (this part)
F36Main PCB faultThe boiler indicates a direct fault of the main board (CVBC). Check for moisture/damage on the board, absent control outputs, and correct power supply; if it persists, replace the PCB.
F25Software faultSoftware fault in the PCB; after cutting and restoring power, if the error persists, the documented solution is to check/reprogram or replace the CVBC. Check for abnormal resets and input voltages before replacing.
A02Flame signal present with burner offThe PCB may interpret an erroneous ionization signal (analog input 'stuck' or ignition stage fault). Check electrode/wiring and ionization reading; if they are correct and A02 persists, the cause is the PCB.
F04Configuración incorrecta de parámetros de tarjetaIncorrectly configured control board parameters (e.g., new PCB without parameterization). Check/load the manufacturer's parameters; if they cannot be saved or become corrupted, replace the PCB.
A23Card parameter errorInternal parameters error of the PCB. Check/adjust parameter settings according to the service manual; if the error reappears, the PCB is the cause.
A24Card parameter errorAnother error with the control board parameters. Check and reprogram parameters; if it doesn't correct or doesn't accept recording, replace the PCB.
How do I know if this PCB is for my boiler?
Verify the reference I39807690 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part. It is a Honeywell part.
What is it used for?
The PCB controls the ignition, modulation, sensor readings, and safety features of the boiler.
Is the boiler not igniting, locking out, or is the control board unresponsive?
After ruling out mains voltage, fuse, and connectors, a damaged PCB causes lockouts, blackouts, or erratic display. Repair the external cause before installing the new one.
Which models is it suitable for?
Part shared by various models (see Compatibility). If your model does not appear, send us a photo of the marking and we will confirm it.
Installation and recommendations
After installation, a technician must adjust the service parameters (type of gas, power settings) and check combustion and safety features.
What does refurbished mean and what coverage does it have?
Part removed from a boiler out of service, inspected and tested. Includes 1-year warranty and 14-day return policy. Delivery within 2–4 working days in the EU.
