I’ve recently received a “Zone fault detected” while running master valve. The weird thing is, I’ve had the master valve disabled in the app the entire time I’ve had the Rachio (around a year). When we bout the house, the master valve was causing us issues but I could not find it so I used the work around of ignoring the master valve and it worked on my old controller as well as the Rachio until this week. I rebooted the Rachio and enabled then disabled the master valve in the app but my zones still won’t come on. Before I rebooted, I got the error and the zone light would flash red on all zones. After the reboot and master valve enabling/disabling, the light flashes blue again on the zones but nothing comes on. Any thoughts?
I have not yet checked voltage as I figured I’d try here to see if any recent updates have been pushed that might have caused an issue or change.
I have the Rachio Gen 3.
