Rain Bird ESP-6TM Won't Turn On Zones, Valves Stuck Open: Valve Mechanical Failure

Controller Buttons Work, But Sprinklers Won't Auto-Start; Main Valve On → Sprinklers Run Uncontrolled

Problem is in the automatic valve, not controller. Valve stuck open (diaphragm or solenoid).

Find faulty valve, rebuild or replace. See irrigationtutorials.com.
