Rain Bird ESP-16-LX+ "Fuse" Display: Finding the Faulty Zone

ESP-16-LX+ shows "Fuse" on display. Need to locate which zone/circuit has the short.

Manual Zone Testing

1. Manually activate Zone 1
2. If "Fuse" appears immediately → Zone 1 circuit fault
3. If not, continue Zone 2, 3, etc.
4. First zone triggering "Fuse" = problem circuit

Field Verification

• Locate that zone's valve
• Check/replace solenoid (most common cause)
• Inspect wiring for damage

Solenoid shorts are 90% of "Fuse" cases. Wiring faults less common but possible.
