Robot lawnmower base station LED flashes or changes color indicating a loop fault, but mower has not yet shown an error.

Safety first: Unplug the base from mains before touching boundary wiring.

• Check terminal connections: Tighten and clean the boundary wire terminals on the Hyundai charging station.
• Inspect splices: Locate and re-make any splices using gel-filled waterproof connectors.
• Use a wire tester: If available, use a boundary wire tester or multimeter to locate high-resistance sections.
• Replace damaged sections: Cut out and replace any visibly damaged wire segments.
