Rachio 3 Blinking white 10 times then 1 Red in quadrant 1. Continues endlessly. Not connected to app. Tried rebooting, then reset and now has lost water schedule in memory.
That sounds like a boot error. Check out this link to get assistance on troubleshooting.
I tried that already. Sill goes back on to a boot error every time.
You may need to replace the unit. I bet it is under warranty and Rachio is awesome about sending replacements, hassle free and quickly.
That was the fix. Just to replace it.
