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)
F11No signal is reaching the main circuit (communication fault with the interface/MMI).The User Interface PCB (S1062000) or its MMI harness do not send/receive data to the main PCB; check 5 V/ground on the interface connector, continuity of the MMI cable, and test with a known good S1062000 interface.
F12No signal from the user interface or remote panel.The user interface (S1062000) is faulty or not powered, and the main PCB is not receiving its signal; check the power supply to the interface, inspect/clean the connector, and replace the S1062000 if it does not communicate.
F18Local user interface fault.Internal fault in the Interface PCB (keyboard/display S1062000) preventing correct operation; check that it powers on/reads keys, measure its power supply, and replace the S1062000 if the fault persists.
F20Interface software incompatible with the boiler.An incorrect interface/display has been installed (different version/software) or without proper coding; confirm S1062000 reference is correct for the model and replace with a compatible interface or reconfigure the appliance code if applicable.
How do I know if this PCB is for my boiler?
Verify the reference S1062000 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.
