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)
F.70Invalid product code (DSN).This appears when the user interface board (display) and/or the main board have been replaced simultaneously without resetting the device identification (DSN) or with incorrect/missing power coding resistors; check the coding/DSN in service mode and, if applicable, try with the original display or reprogram/adjust the coding.
ConnectionNo communication between the main PCB and the user interface.A fault in the display PCB (0020195591), its power supply, or the harness/connector can interrupt communication with the main PCB; check power supply voltages to the screen, connectors/wiring, and, if possible, temporarily replace the screen with a known working one to rule out the main PCB.
How do I know if this PCB is for my boiler?
Verify the reference 0020195591 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.
