Greenstar 12i boiler not working

[jamesosborne]

Hi, my Greenstar 12i has stopped working. No fault lights at all? I turned off the cental heating during the day because it was getting to hot, turned it back on and nothing. I have re-set boiler and turned off then on and still nothing, the house is freezing. Would it be the out side pipe? I would be very grateful of any help.

Do the boiler lights do anything if you turn off at the wall and turn back on? Have you checked the fuse?

When I turn it off from the master switch all the lights momentarily come on for a second, then nothing.

Is there a gurgling noise when you turn the boiler on?

How is it wired, is it a built in timer or external clock?

Are there any zone valves?

No noise at all when I turn on the boiler. There are valves going into it, gas and what looks like water. Pressure is down to 1. Not sure if it has an external clock or not, how will I know?
