Ideal W boiler

[benjamin]

Hello,
My boiler made a banging noise when I was upstairs. Now I can't seem to light the pilot. I depress the button to allow gas to pass, but no gas seems to be coming through.
Any ideas?
Thanks

check the pump - i bet its dead and not shifted any heat thus cutting out on the overheat stat. replace pump and reset over heat stat
