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.20Safety shutdown: temperature limiterIf the 3-way valve (priority valve) is disconnected/seized/blocked, it does not switch the circuit and the water stagnates in the primary, causing overheating and triggering F.20. Check by reading d.35 (valve position) and actuating/adjusting it from d.70 or during bleed tests (the boiler sets the valve in the middle position) and check the motor connection and possible mechanical blockage.
How do I know if this 3-way valve is for my boiler?
Verify the reference S1079100 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 3-way valve diverts the water between the heating circuit and the domestic hot water (DHW) circuit.
Does it provide hot water but not heat the radiators (or vice versa)?
Typical symptom that the valve or its motor is not switching; check the actuator motor and ensure the body is not seized.
