What does fault code A33 mean in Ariston?

Problem with the fan (lockout type A). The Fime GR00540P extractor does not start or spins out of range; the PCB detects absence/anomalous signal from the tachometer and locks out. Check power supply to the fan, free rotation of the impeller, and Hall/tachometer signal to the PCB.
