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)
302Communication error (internal electronics)The main PCB may lose communication with the display/modules (bus) due to a fault in the PCB itself (transceiver/5V/3.3V) or cold solder joints. Check voltages on the PCB, harness, and connectors; rule out the display by testing another one and, if the issue persists, replace the PCB.
303Main PCB faultThe self-diagnosis detects a fault in the PCB (CPU/memory/regulators) that prevents control. Check the power supplies and grounds of the board, and if there are no external causes, confirm by replacing the PCB.
305Main PCB faultInternal fault of the PCB causing a safety lockout. Check 230V/5V, grounds, and connectors; if everything is correct and the error reappears, replace the PCB.
306Main PCB faultRecurrent fault in the PCB (circuitry/relays/regulation). Check sources and communications on the board; if there are no external anomalies and the error persists after a reset, replace the PCB.
307Main PCB faultInternal fault of the PCB detected by self-check. Check voltages/bus and inputs; if sensors and wiring are OK, the solution is to replace the PCB.
How do I know if this PCB is for my boiler?
Verify the reference 65116585 06 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.
