Robot mower stops near the boundary and displays E2; may occur intermittently when approaching the edge of the lawn.

Safety first: Switch OFF the mower and unplug the charging station before adjusting the boundary system.

• Check for nearby metal: Look for metal edging, rebar, metal drainage grates, or buried cables running parallel to the boundary wire. Move the wire 10–20 cm away from such objects.
• Shorten or simplify the loop: If you have long narrow corridors or many islands/exclusions, temporarily simplify the layout to see if the error clears. Excessive loop length or complex routing can weaken the signal.
• Inspect all connectors: Replace any green/white gel connectors that look damaged, corroded, or waterlogged. Poor joints can attenuate the signal.
• Check wire depth: Ensure the boundary wire is pegged close to the surface (or buried shallow as per Flymo instructions). Very deep burial can weaken detection.
• Test station output: With the wire disconnected, some models allow a loop test mode. If the LED still indicates a fault, the charging station electronics may be failing.

If relocating the wire and renewing connectors does not resolve the issue, the charging station assembly may need replacement.
