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)
F11Communication error between the main PCB and the user interface.The PCB S1208500 manages the data bus with the interface; a fault in the electronics/power supply of the board or in its soldering can interrupt reception/transmission. Check the harness and PCB–display connectors and measure 5 V/eBUS on the board; if everything is correct, cross-check with interface/test board.
F12Communication error between the user interface and the main PCB.The S1208500 PCB may lose communication due to an internal fault (source/bus/micro) or loss of power to the interface. Check the interface-PCB wiring and voltages (5 V/eBUS) on the board; if OK, replace the PCB or the interface to rule out.
F13Main PCB fault.Inherent fault of the PCB S1208500 (EEPROM/CPU/power supply or tracks), which locks the equipment. Check the voltages on the board, inspect the solder joints, and confirm by replacing with a new S1208500 if necessary.
F20User interface incompatible with the main PCB.After changing the control board/interface without the correct coding, the PCB S1208500 detects incompatibility and locks. Verify compatibility of versions and product coding; reparameterize or replace the corresponding control board/interface.
How do I know if this PCB is for my boiler?
Check the reference S1208500 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part. It is a SYMS piece (SYMS17.0).
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.
