Rachio 2 dont stop watering

Hi, I have a friend he just bot a Rachio2. The issue is its dont turn off after a watering circle finish in the app. He already checked the solenoids all of them are working, and also a wiring is correct. He is using a 0.8 amp adapter.

Thanx

AC or DC adapter? One will work, the other will cause zones to stay on.
