My Rachio has worked perfectly for the last few years, but suddenly it has stopped. 
My unit says its working and the app says it is watering zones, but none of them turn on anymore. I haven’t changed or touched the wiring or any of the plumbing/water. I’ve tried reprogramming the unit, changing app settings and power cycling the system but the system will not water. I have tried to manually turn on one zone, and the app shows it is functioning, but there is no water. I physically am able to get zones watering from the controller (not Rachio, the manual controller).
I have a version 1 Racho with 16 zones (I was one of the very first buyers).
