How to Fix / Troubleshooting

Safety: Network troubleshooting does not require opening the mower; only open it if hardware inspection is needed.

  • Check signal strength: Ensure the TerraMow charging station is within range of your Wi-Fi router. Test with a smartphone at the station's location.
  • Reset network settings: Use the mower menu or app to forget and re-enter your Wi-Fi credentials.
  • Power cycle: Turn the mower OFF and unplug the charging station for 60 seconds, then restore power and retry the connection.
  • Inspect antenna (advanced): If comfortable, open the housing and verify that the Wi-Fi antenna cable is securely attached to the TerraMow connectivity module.
  • Replace module: If E16 persists and other devices connect fine, the TerraMow Wi-Fi module may need replacement.
