went to a breakdown on a procombi HE other day, no ignition. Removed venturi and cleaned then replaced .. still nothing. Checked APS and that was fine so i was a bit stumped. Rang eric @ technical and he reckons its an airflow problem .. and he wasnt wrong! removed a small boxing cover at top of boiler which was in kitchen to find this beauty!
I had to stand back for 2 mins in shock! boiler was installed in 2011 and had services every year by same engineer. No benchmark filled/paper work .. nothing. I asked him who it was and its a local guy round our way that seems to eb doing alright for himself.
Flue was too short, not sealed inside and out. inner flue connected at elbow but not terminal .. and to top it off condensate was hanging a meter off the wall dripping into space.
Capped off as customer couldnt afford the repairs unfortunately.
