      [Webinar] Electric Circuit Troubleshooting and EEPs   12/05/2016

      I have a special topic for tonight's Office Hours webinar on electric circuit troubleshooting and EEPs. If you've taken the Fundamentals course or watched any of my Youtube videos, you know that EEPs are a topic near and dear to my heart. EEPs = Electrically Equivalent Points. Identifying EEPs on a schematic is a key skill for any appliance tech today.  Another special feature about this Office Hours: in addition to the usual Academy students and Professional Appliantologist members, Senior Appliantology Fellows and Legacy Techs at Appliantology are also welcome to join us for this Office Hours. Just click into the topic below to RSVP and to get the connection info.

Buderus GB142-24 issues

2 posts in this topic

Just had the system installed and having some teething problems, hoping somebody can shed some light.

Install went with no real issues and boiler makes all the heat I need. It's setup to do Indirect hot water, made by Bradford-White model sw250rl.

Here's the issue, when calling for hot water I get error codes that I believe are casued by air pockets.

The system fires up and after about a minute I hear a solenoid open and I get some fluctuations in pressure which shuts the system down and gives either a "2F" or "4A" code.

These have nothing to do with either air pockets or fluctuation in pressure.

When making heat the system runs fine, no fluctuations and no trouble codes.Only problems when making hot water.

I've bled the system a few times and it seems to have helped but I can't seem to get it to run effortlessly.

I was told that both the heat loop and hot water loop are connected to each other so why is there only an issue on one loop?

I'm having the installer install another bleeder on the system but there has to be a better way for this thing to run.

Thanks for any help you guys can give me, Eric
