Fixing 'Power Off' Errors on an Orbit 6-Zone Timer

Orbit Timer Shows "Power Off" After Solenoid Replacement

The "Power Off" message indicates the controller detected a short circuit. If it persists after replacing a solenoid, the fault may be in the field wiring or the wrong solenoid was replaced.

Isolate the Fault

1. Disconnect the two wires from the suspect solenoid at the valve.
2. Activate that zone from the controller.
3. If "Power Off" still appears, the short is in the wiring between the controller and the valve.
4. If the message disappears, the solenoid (or its connection) was the culprit—ensure the new solenoid is correctly wired and the valve operates smoothly.

Also verify that the common wire is intact and all wire nuts are waterproofed.
