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)
33Factory settings CRC error: invalid EEPROM data from "Masterreset" (CRC error in default values).Corruption of the EEPROM in the control board; after reset, if the code persists and the parameter plug/BCC is correct, the action indicated by the manufacturer is to replace the board. Verify 24 VAC/5 V voltages and connection of the parameter plug before replacement.
31Burner CRC error: invalid burner EEPROM data.Memory fault in the PCB/FA; if it persists after a reset, the manuals indicate replacing the PCB. Check wiring and power supply before replacement.
30Boiler CRC error: invalid EEPROM data for the 'boiler' assembly.Dataset corruption in the PCB; after a reset, if it is not corrected, the official procedure involves replacing the PCB. First, check voltages and ensure there are no pending parameterization/updates.
32Voltage fault 24V: fault in the 24 VAC supply (check fuse on PCB in *GB).Fault in the 24 VAC supply generated/monitored by the PCB (fuse/regulator on PCB). Measure 24 VAC at terminals and PCB fuse; if everything is correct and 32 persists, replace the PCB.
99Internal electronic/PCB error (combustion automation system fault).Internal fault of the control/FA on the PCB; the brand indicates checking connections (e.g., fan PWM and network) and resetting; if it persists, the PCB is faulty and must be replaced.
How do I know if this PCB is for my boiler?
Check the reference 2799110 printed and ensure your model is on the list of compatible ones; also compare the connections with the original 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.
