Water pressure sensor Gloworm 18sxi

[studmuffin]

Hi, is changeing a water pressure sensor on a gloworm ultracom 18sxi easy ? Could it be a diy job ?

Ive got F9 flashing up on my boiler when it fails to ignite, its not low water pressure as this was fixed last year with a new pressure exspansion vessel, and pressure is still at 1.3 bar, so im assuming changeing the water pressure will fix the problem....

Thanks guys

Firstly go to the Forum Index scroll down to Plumbing Forum and then across to 'Boiler Manuals', click, then down to Gloworm and look for your model installation; if _18sxi it will be under section 15.20; if model 2_18sxi will be 19.4.4 however the diagram numbering does not tie up with the text..
If another model mark be more specific.
Please report back so we can all learn!
