Hi,
I am looking for some advise for an intermittent central heating problem. So far 4 senior engineers have visited 3 from insurance company & 1 privately & none could diagnose the issue. Below is the snippet:
Problem - Boiler runs for few minutes sometimes hours & then cuts out & goes into lockout mode.
Boiler make is Baxi main 15 HE - system boiler - installed November 2007 by previous owners
First Plumber Visit - Within 10 minutes engineer said the circulation pump needs changing as the boiler is running fine. Pump changed, system ran for a day just fine & then same problem reoccurred.
Second New Plumber Visit - Within 10 minutes engineer said the air pressure switch needs changing. Air pressure switch changed, system ran for a day or two just fine & then same problem reoccurred.
Third New Plumber Visit - Within 10 minutes engineer said now then you must have sludge in your system, power flush required. Insurance won't cover for that so get quotes & get it done privately.
Fourth New Private Visit - Called for Power flush so he drained the system, clear water coming out, no sludge in the radiators so he called off power flush & said not required. He cleared header tank which had some rust, checked cold water tank which was clear. Buffed boiler from inside & cleared any dust etc (serviced it essentially), installed magnaclean, poured inhibitor 1000.
Reset & Hurray Boiler working again but I knew it may not last long, come morning it's again in lockout mode 🙁.
We don't want to change the boiler as that should not be required. What's your thought & what are my options?
Thanks
