Guys
Just wanted to say thanks for the feed back, I desided to get the experts in and you where right when you identified the fan modulation board.
The DHW can continue to function in a normal manner whilst the CH fails to ignite correctly. The Gas guy who looked at the boiler was himself...
Thanks Pete. will check out guarantee,
SortedPlumbing, would fan module be issue if DHW is working correctly? as in both DHW and CH the fan has to run full speed before ignition, could you please explain further
thanks KevinJP
I have a Ravenheat CSI 85 A (T) combi condensing boiler which is approx 14 months old.
Until today it has been working fine when a fault appeared on the CH side
The fault only affected the CH aspect and the DHW is working completely normally.-
Normal ignition cycle. Fan Full speed...
