I have the above boiler which was working fine. I switched it off at the mains to clean the magnaflow. When I switched back on the blue light is flashing. Reset does not clear it. Any adeas or advice?

My money would be on fan PCB, you'll need a gas bod to sort it.

Is it the standard 24i junior or Greenstar 24i junior?

I dont think so, I turned them 90 deg . Or are you suggesting 1 is jammed closed? I could take the magnaclean of and open in a bucket?
