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.318The 3-way motorised valve is not moving.The actuator/motor of the V3V (Ref. 0020020015) is seized, faulty, or without power, preventing position change; check by executing P.008 to force it to the middle position and measuring voltage/continuity to ensure the motor moves the stem.
F.326The hydraulic test of the sensor and the actuator has determined that at least two hydraulic components are not functioning.The motorised V3V is blocked or not responding (loose connector/interruption), causing autotest fault; check its stroke during the autotest (e.g., P.008) and inspect the motor connector/harness and ensure the actuator moves the shaft without obstructions.
