Alpha cb24 fan fault or blocked flue

[mutley racers]

Hi all. I just want confirmation on my diagnosis of a cb24 fault. Basically pump runs but fan doesn't and no 240v at fan terminals on fan or pcb. So it's a PCB fault? Lights flashing simultaneously which is a flue fault. Alpha technical not answering, only taking messages.

Thanks

Yes mut pcb if you haven't got voltage at the fan connector or even at the aps
