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)
F.63Fault: EEPROM.Defective EEPROM in the integrated control/display board; the equipment detects it as an electronics fault. Check if it reappears after a reset and, once spikes/wiring are ruled out, follow the manual: diagnosis and replacement of the PCB.
F.64Fault in the electronics / NTC.Short circuit in flow/return NTC or defect in the measurement channel (ADC) on the control board itself; if the NTCs and their wiring measure correctly, the cause is the electronics of the PCB. Verify by measuring NTC/cables and, if they are correct, replace the PCB.
F.70Invalid appliance code (DSN).After replacing the display and PCB simultaneously (integrated in this model), the DSN/coding resistor was not parameterized; the PCB remains without valid identification. Verify by entering d.93 and programming the correct DSN or checking the coding resistor.
How do I know if this PCB is for my boiler?
Verify the reference 0020028476 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.
