Robot mower displays E11 and stops near the charging station or boundary transitions

Safety: Unplug the charging station from mains before working on wiring.

• Check station connections: Verify the guide wire is connected to the correct terminals on the Makita charging station and that screws are tight.
• Inspect guide path: Follow the guide wire route from station into the lawn. Look for cuts, exposed copper, or damage from tools or rodents.
• Repair damage: Use waterproof connectors to repair any breaks. Ensure joints are buried or pegged securely.
• Continuity test: With both ends disconnected, measure resistance across the guide wire. Infinite resistance indicates a break.
• Power and test: Reconnect, power the station, and check for normal guide wire indicator. Clear E11 on the mower and test docking/undocking.

If the guide wire is intact but E11 remains, the guide output circuit on the charging station may be defective and need replacement.
