Possible Causes

Dirty or corroded charging contacts, Misaligned mower in station, Faulty low-voltage power supply, Broken charging contact springs

How to Fix / Troubleshooting

Safety first: Unplug the charging station power supply before cleaning contacts.

  • Clean contacts: Wipe the metal contacts on both the mower and station with a dry cloth. For light corrosion, use a fine abrasive pad gently.
  • Check alignment: Place the mower in the station and ensure it sits fully against the stops and the contacts touch evenly.
  • Verify power supply: Confirm the transformer is plugged in and warm to the touch after some time. Replace if cold and no output is present.
  • Inspect contact springs: Ensure the spring-loaded contacts on the station move freely and are not stuck or broken.
