Hi, I have had a Rachio 2nd gen sprinkler controller (model 16ZULW-B) installed for a couple years now with no issues, but suddenly it has stopped working. The software and hardware seem to be working, but when the sprinklers are supposed to go off, or when I try to do a quick run, none of my sprinkler zones actually turn on.
I have manually opened the bleed on one of the solenoids and got some of my zones to work, so it appears that there isn’t a water delivery issue (i.e. closed water main valve somewhere).
I have also unplugged / plugged back in the controller, and I have unplugged the ‘C’ wire in the controlled and plugged it back in to see if that helped, but did not do anything.
Since the water is going to the zones ok, and since all the zones have stopped working together it seems like there is an issue with the controller. I don’t see any issue with wiring from the controller to the different zones.
Any help appreciated! I do have a multimeter, just need some guidance on how to use it to help in this case, thanks
