My Ravenheat WhiteStar LS100T combi boiler has been having a problem with the hot water. CH is fine. Basically unless you have the taps on pretty much full blast the boiler does not fire up. The problem has been gradually getting worse as in the water needs to be put on faster and faster in order to get the boiler to fire.
Having done quite a bit of searching on this forum I am putting this down to the diverter valve.
However, it seems I could just buy a new Diaphragm and replace that, but from what I have read the spindle on the Ravenheats are shorter than the standard ones that come in a repair kit.
Questions:
1. Is it possible to buy a diaphragm for a ravenheat that comes with the correct spindle size and if so where from? I have read that you can swap the spindles but it is fiddly.
2. The boiler has excellent access all round so I am wondering if I will actually need to remove the whole diverter valve to do this job?
3. If I will need to remove the whole valve does anyone know what size washers I need to get for this model for when I am refitting?
Thanks very much for your help.
