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)
97EFrequency of the PCB (control board) incorrectly configured (Hz).The PCB remains with 50/60 Hz incorrectly programmed (typical after replacing or reconfiguring it). Verify and correct the frequency in service parameters; if it does not accept or reappears, replace the PCB.
98EInternal PCB fault.Self-diagnosis detects an internal fault in the PCB (contacts/relays, micro or parameters). Check voltages/grounds and connections to the gas valve; if it persists after reset, replace the PCB.
99EInternal PCB fault.Same as 98E: internal fault documented in the PCB. Check power supplies and wiring; if it repeats, replace the board.
55PCB not calibrated/not programmed.After changing the PCB or data loss, the boiler requires calibration/adjustment of the board. Execute the service calibration function; if it fails or does not save, reprogram or replace the PCB.
135Internal PCB fault.The boiler's self-diagnosis detects an internal fault in the PCB; some guides suggest checking the wiring between the board and the gas valve. Verify connections/grounds and, if they are correct, replace the board.
How do I know if this PCB is for my boiler?
Verify the reference V9158641 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part. It is an Ineco 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.
