Start up problems

Rachio 3 was installed last season and worked fine, shut down for winter no problems.
Turned on the water for the system and Rachio 3 immediately started watering without a schedule being set! Further, I could not stop it and ended up shutting the water again.Any thoughts?

@Fixxer - were the solenoid bleed screws left open after the winter shutdown (i.e. blowout)? If the Rachio is unplugged and water turned onto the system and water comes out of one or more zones then I’d think it would be a valve issue - stuck open or left open - rather than a Rachio issue.


What DLane said…there is an issue with the valve somewhere, either the bleeder left open, or maybe a diaphragm failed over the winter…
