Possible Causes
How to Fix / Troubleshooting
Safety first: Turn the main power switch on the mower to OFF and unplug the charging station from the mains before working on the boundary system.
- Check charging station LEDs: Most Flymo robot stations have an LED that indicates loop status. A solid green usually means OK; flashing or off can indicate a loop fault. Refer to your specific model manual for LED meanings.
- Inspect boundary wire at the station: Ensure both boundary wire ends are firmly inserted into the correct terminals on the charging station. Remove, trim 5–10 mm of insulation, and reinsert if corroded.
- Walk the perimeter: Follow the boundary wire around the garden looking for visible cuts, chew marks, or places where the wire has been pulled up or damaged by edging tools.
- Test for breaks: If you have a multimeter, disconnect both ends of the boundary wire from the station and measure resistance between them. A very high or infinite reading indicates a break. Use wire repair connectors to join broken sections.
- Check couplers and splices: Open or replace any suspect gel‑filled couplers. Poor crimps or water ingress can interrupt the loop signal.
- Test the station: After repairs, reconnect the wire, plug in the station, and check that the LED shows a healthy loop. Turn the mower back ON and try to start a manual mow.
If the loop LED still indicates a fault and the wire is intact, the loop signal generator in the charging station may be defective and the station may need replacement.
