Recently my old baxi solo pf 30 has been making a vibrating shaking noise after it has finished it's cycle, usually around 5 mins after, the boiler seems to be working fine, occasionally the fan will struggle to get going but this is remedied by turning the boiler on and off, the pcb was replaced soon after I moved in, does this sound like a fan issue, it doesn't make this noise when the boiler is running. But for a millisecond when I first turn it on.
