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)
55PCB not calibrated.After replacing the PCB 7691279 or losing parameters, the boiler detects that the gas valve has not been electronically calibrated. Verify by entering the installer menu and execute the automatic calibration (or adjust F03/F12 according to the manual) and confirm that the error disappears.
135Internal fault of the card.Self-diagnosis of PCB 7691279 detects internal fault. Check power supply and connections; if after reset and checks the issue persists, the PCB is faulty and must be replaced.
83Communication problem between the boiler PCB and the control unit.Communication bus fault on PCB 7691279 (eBUS/OpenTherm) may prevent communication with the control board. Check wiring and test with a known control unit; if the issue persists, the PCB is the cause.
84Communication problem between the boiler PCB and the control unit.Same as E83: fault in the communication circuit of PCB 7691279 or short circuit in the bus. Check bus continuity and rule out the control board; if communication is still absent, the PCB is faulty.
86Communication problem between the boiler PCB and the control unit.Same as E83/E84: communication fault in PCB 7691279. Check bus and control board; if there is no improvement, replace the PCB.
87Communication problem between the boiler PCB and the control unit.Same as E83/E84/E86: communication interface fault on PCB 7691279. Check wiring/unit; if it persists, the PCB is the cause.
168EInternal error of the boiler PCB.In Platinum Compact 24/24F, this code indicates an internal anomaly of the PCB. After checking power supply and external interferences, if it is not restored, the PCB 7691279 is defective.
How do I know if this PCB is for my boiler?
Verify the reference 7691279 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.
