3-way switch not working in "Auto"

[ceritz]

I am looking to see if someone could help me trouble shoot a Electric Brewery Supply BCS Control board that I had made for my brewery. It is a 50amp box with capability to run 2 electric elements. The BOIL switch, which is a 3-way switch does not work when switched to "Auto". The light does not come on and there is no sounds of the relays clicking when turned on. There are occasions, when turned back and forth from "Auto" to "Off" many times, the switch does come on but usually blinks and clicks on and off rapidly. There have been a couple times that it does stay on but only for several minutes. The switch works just fine in the "On" position. If there is anyone who may know what I could do to troubleshoot or know what parts I would need to replace, I am all ears.

Here are a few pics to help illustrate the issue.

Sounds like either the physical switch could be bad or the wiring of the auto input/output is not right. Have you checked with Electric Brewing Supply?

Hi JonW. I have checked in with Electric Brewing but I am still waiting to hear back from them. Just wanted to see if there was something blaring that I could troubleshoot. I'm not too great with the electrical side of things.

BTW, your brewery build (on HomeBrewTalk) was my inspiration for this one. Thank you for posting all that you did. So close to brewing now, just need that switch to work.

Thanks! I'd love to see more pics of your rig and especially the plumbing. Do you have it posted anywhere?

Not yet but I will soon. I will post when I take a few more pictures.
