Rachio 2 zone won't turn off

@hk1975, to increase the odds that you’ll get a reply I’d mention @Retired (like that) in the post or send them a direct message by clicking on their icon and then the message button.

They may have tried what I suggested: turn off the water, remove the solenoid valve, turn on the water to flush out the valve through the solenoid opening, turn off the water and put the solenoid valve back in.
