Mower stops near the edge of the lawn and displays E05 boundary wire short or overload.

Safety: Power OFF the mower and unplug the dock before troubleshooting.

• Inspect recent work areas: Focus on places where soil was disturbed, edging was done, or heavy objects were placed. Look for pinched or cut wire.
• Check connectors: Open any in‑line boundary wire connectors and inspect for moisture or corrosion. Replace with new waterproof gel‑filled connectors if needed.
• Isolate sections: Temporarily disconnect half of the boundary loop at a mid‑point (using temporary connectors) to see if E05 clears when only one half is connected. This helps narrow down the shorted section.
• Remove from metal contact: Ensure the wire is not tightly wrapped around metal stakes, fences, or rebar that could cause interference or abrasion.

If the short cannot be located visually, consider using a wire break/short locator tool or contacting a technician.
