I have this boiler to heat and provide hot water for my home. I have had a total of three of these boilers. The first two were recalled by Viessman and replaced. The problems with the recalled boilers was I had to keep replacing ionization and ignition electrodes. There was also some risk of carbon monoxide leakage.
The last one was replaced in 04/2021. So it's been working fine for over a year. Recently (October 2022) it's been shutting off with error code EE (combustion failure) every day, sometimes multiple times per day. I just had my plumber come out (Nov 2022) and replace the ionization electrode for $300. The plumber said this is a constant problem with this boiler and be prepared for the failures to continue. I'm getting a bad feeling again about this boiler again.
I've been to Viessman's website where you can input your serial number and see if it's a recall boiler. My number (75547031010311120 -B2HB 160) was not a recall boiler for now.
I have a question if any customers or professional plumbers are aware of this issue and can share any advice?
