Husqvarna Automower 430XH Robotic Lawn Mower BOUNDARY WIRE BREAK Error Fix: Confirmed Boundary Wire Break

The system has confirmed that the boundary loop wire is physically broken — this is more specific than "No Loop Signal" which can also be caused by a station power issue; the charging station diagnostic typically indicates the loop status; use the station test function or an AM radio tuned to a low frequency near the wire to help locate the break (the signal is audible until the break point); repair the wire with weatherproof connectors and test the loop before restarting the mower; consider burying wire splice connections to protect them from mechanical damage
