Potterton Ultra 2 "Need Help"

[David_D]

I have a Potterton Ultra 2 Boiler. When I went to turn on the Boiler it started making very strange noises. It seemed to be attempting to start and then can a a bang noise followed by a big green spark which blue the fuse on the spur. It looked like the spark was coming from the injector at the bottom left of the boiler. Has anyone ever had any experience of this type of fault before? Thanks for your help.

not familiar with this model but usually any big blue spark is going to leave a black mark which will help id where its coming from
