Help with JC Spot Free

[slash007]

I noticed that my reject meter was staying at 0 when spot free was in production, so I figured it was the flush valve. I checked it and everything was good with the valve itself. I actually just replaced it two years ago, so it's fairly new. I then tested while it was running and the flush valve does not seem to be getting 24v, which would explain the issue if I'm testing correctly. Issue is that I have no idea why it wouldn't get 24v and where to look in the electrical cabinet to find the issue. Any insight would be appreciated.

On the super saver the spot free is controlled by the PLC.

I'm not sure of the specific wiring but last year I was having some issues and had to recently change my PLC out on a 1999 pump unit. The replacement PLC was around $600 or so IIRC.

Well that sucks lol. Explains why I couldn't find the wire. I tried tracing it and it seemed to go to the PLC, but I thought that was wrong, so I stopped. Is it a separate PLC from the one that controls the triple foam?

No it is the same one. That's the main thing the PLC does is triple foam and RO functions
