Possible Causes

Disabled Bluetooth/Wi‑Fi in settings, Failed wireless module on main board, Antenna cable disconnected or damaged

How to Fix / Troubleshooting

Safety: Wireless troubleshooting does not require opening high‑voltage components, but keep the mower stationary and blades stopped.

  • Check settings: On the mower display, ensure Bluetooth/Wi‑Fi is enabled. In the Yarbo app, remove and re‑add the mower if necessary.
  • Reduce distance: Move your phone within 1–2 m of the mower and avoid interference from other strong Wi‑Fi devices.
  • Restart devices: Power cycle the mower and restart your phone. Try pairing again following Yarbo's pairing procedure.
  • Inspect antenna (advanced): If you can safely access the antenna area, verify that the antenna cable is firmly connected to the wireless module or main board.

If E17 remains and no wireless connection is possible, the Yarbo Wireless Communication Module or main control board may require replacement.
