5. Troubleshooting

If you encounter issues with your Sunseeker L22 Plus, consider the following common troubleshooting steps:

• Mower not following boundary wire: Ensure the boundary wire is correctly installed, taut, and free from breaks. Check connections to the charging base.
• Mower getting stuck frequently: Clear the mowing area of any small obstacles (toys, branches) that might not be detected by sensors. Ensure the terrain is not excessively uneven or has deep ruts.
• Poor cutting performance: Check the blades for sharpness and replace if dull. Adjust the cutting height setting to suit your grass type and conditions.
• App connectivity issues: Ensure your mower is within Wi-Fi range and that your home network is stable. Restart both the mower and the app if problems persist.
• Mower not charging: Verify that the charging base is powered on and that the mower is correctly docked. Clean the charging contacts on both the mower and the base.
