Robot mower base station LED flashes or changes color, but mower shows no error and behaves unpredictably.

Safety first: Unplug the charging station from mains before touching wiring.

• Tighten terminals: Remove the boundary and guide wires from the station, trim the ends, and reinsert firmly into the correct terminals.
• Clean corrosion: If terminals are corroded, clean them carefully or replace the station if badly damaged.
• Check for new interference: Consider any recent installations (electric fences, cables) near the boundary and move them if possible.
• Monitor LED: After reconnecting, plug the station back in and verify that the LED indicates a stable, healthy loop.
