Buderus GB 142 shuts off, code 4A, code 2 18, P 117
I built my home in Windsor, MA 2006-2007. Moved in in June ‘07. Had Buderus GB 142 with IDHW. Ran ok for about 6 yrs. Then started having constant problems. Changed service providers, and they months or so, then some of same problems. They were and are a Buderus service provider. Any idea of who in Western Massachusetts knows what they’re doing on this complicated box. Seems like it cost me $500 to $700 every time something goes wrong. Would I be better off just getting a more reliable boiler rather than trying to keep fixing this “High Efficiency “ one?
