6. Troubleshooting

If you encounter issues with your Rachio 3 controller, consider the following troubleshooting steps:

• No Power/Light Bar Off:
  • Verify the power adapter is securely plugged into both the controller and a working electrical outlet.
  • Check your home's circuit breaker to ensure power is supplied to the outlet.
• Wi-Fi Connectivity Issues:
  • Ensure your Wi-Fi network is 2.4 GHz, as the Rachio 3 primarily uses this band for initial setup and consistent connection.
  • Restart your Wi-Fi router and the Rachio controller.
  • Move the controller closer to your Wi-Fi router or consider a Wi-Fi extender if the signal is weak.
  • Refer to the in-app Wi-Fi troubleshooting guide for specific steps.
• Zones Not Watering:
  • Check the wiring connections for the affected zone(s) at the controller. Ensure wires are firmly seated.
  • Verify that the zone is enabled in the Rachio app and that no skips (Rain Skip, Freeze Skip, Wind Skip) are active.
  • Manually run the zone from the app to test if the solenoid is functioning.
  • Inspect the sprinkler heads and lines for any physical obstructions or damage.
• Inaccurate Weather Skips:
  • Confirm your location settings in the Rachio app are accurate.
  • Adjust the Weather Intelligence Plus thresholds (e.g., rain amount for skip) in the app settings if needed.
