Hello all,
I have a Potterton (probably now Baxi/Potterton) Envoy 40 condenser boiler which is acting up. It seems to switch between apparently working ok (albeit briefly) then flicking between code 8 and code 0 before cutting back in for a few minutes before starting the cycle again. For the life of me, I can't find any worthwhile information elsewhere on this boiler.
Can anyone please spare my sanity and give me a step for a hint on what fault code 8 is?
Much obliged:
