How to Fix / Troubleshooting

Safety first: Turn OFF the mower before cleaning or opening covers.

  • Step 1 – Check settings: In the Sunseeker menu/app, ensure the rain sensor function is enabled and delay times are set.
  • Step 2 – Clean sensor: Wipe the rain sensor area clean and ensure it is exposed to the sky.
  • Step 3 – Inspect wiring: Verify the rain sensor cable is connected to the main board.
  • Step 4 – Simulate rain: Lightly dampen the sensor with water (with mower OFF) and then power ON to see if it responds after the configured delay.
