Robot mower frequently loses boundary and drives outside the lawn area without showing a code

Safety: Unplug the charging station before modifying the boundary wire.

• Check wire depth: Ensure the boundary wire is at the recommended depth (often on the surface or shallowly pegged, not deeply buried).
• Inspect splices: Replace any non-original or corroded connectors with Bosch-approved gel connectors.
• Shorten loop if possible: Remove unnecessary detours to reduce total loop length.
• Re-route away from interference: Keep the wire away from mains cables and metal structures.
