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)
ALL 88Internal error (component protection on the board).The PCB enters protection mode due to an internal hardware fault. Check voltages 230V/5V/12V on the PCB and isolate peripherals; if it reappears after reset/autocalibration, replace the PCB.
ALL 98Software error, card start-up.The microcontroller on the PCB does not complete the boot. Try reset and auto-calibration; check for stable power supply and, if the issue persists, reprogram or replace the PCB.
ALL 99Generic fault on the PCB.The PCB self-diagnosis detects a non-specific fault. Check the power supply and disconnect loads; if the error persists, replace the PCB.
ALL 77Maximum/minimum absolute limits error of current EV2 SGV.The driver stage of the board that controls the EV2 modulator delivers current out of range. Measure signal/current to the modulator and wiring; if the EV2 valve is OK, the probable cause is the PCB.
ALL 78EV2 SGV upper current limit error.Excess current in the modulation circuit controlled by the PCB. Check wiring and modulation current; if the EV2 valve is correct, replace/repair the PCB.
ALL 79Fault due to lower current limit EV2 SGV.Modulation current below threshold due to output/driver fault on PCB or wiring. Check the signal from the PCB and the condition of the gas valve; if it functions, the cause is the PCB.
ALL 95Fault due to micro interruptions in the flame signal.Unstable ionization reading due to flame entry fault on the PCB or noisy power supply. Measure ionization microamps and voltages on the PCB; if electrode/gas are OK, replace the PCB.
How do I know if this PCB is for my boiler?
Verify the reference 6324920 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.
