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)
60-90Flame relay is not working properly or is stuck.The flame relay is on the PCB; if its contacts stick or its coil fails, the electronics do not manage/detect the flame and it locks out. Check the coil voltage and relay switching on demand on the PCB.
50-70-90Safety relay fault: does not close after demand.The safety relay is integrated into the PCB; if it does not close due to damaged contacts/cold solder joints or a control circuit fault, the PCB does not power the safety/gas chain. Check the PCB for coil activation and relay contact closure after the command.
40-60-70-90Safety relay: very long start-up timing.The ignition timing is managed by the PCB through the safety relay; if the relay/control circuit of the board does not switch in time, this code appears. Check control signals and timings on the PCB and the effective switching of the relay.
How do I know if this PCB is for my boiler?
Verify the reference 122123000 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.
