Hi guys
Does the worcester cdi have an internal bypass?
Long story short ive done some ufh on a worcester cdi not a big system 7 rads and ive added a 10m2 conservatory pack.
Both zone valves ( for ufh and radiators ) have been left locked open untill spark goes back. Just over a week later boiler developed EA fault and goes to lockout after 4 attempts sometimes it lights briefly.
Customer has got boiler cover so they have been out. First said the condense was blocked. Then something else. Now they saying its pressure build up as i havnt fitted a bypass.
Just want to double check before i tell him hes wrong
