i have a vokera excell 80 SP combi boiler.
My problem is that the boiler is not firing up for either HW or CH.
i know i should leave it all to the experts, but you know what people are like. the boiler will fire up if the front cover is off but the moment you refit the cover and tighten all the screws the boiler goes out.
i have looked on the internet and as far as i can tell the fan is running as soon as the HW or CH call for heat. (but its not running all the time)
To me (bearing in mind i know nothing) it seems like it is not getting any air as the boiler shuts down as soon as i put the cover on it. Will run fine if the cover is left off so its getting air . my theory is probably all wrong. but would appriciate any help suggestions of what may be wrong. and how i cure it
