Robot lawnmower shows E06 and cannot find or follow the boundary wire.

Safety first: Turn OFF the mower and unplug the charging station from mains before working on the boundary system.

• Check charging station LEDs: Verify that the station shows normal boundary signal status according to the Ecovacs manual. A flashing or off LED often indicates a loop break.
• Inspect boundary wire connections: Open the terminal cover on the charging station and ensure both boundary wire ends are firmly clamped and not corroded.
• Walk the perimeter: Follow the boundary wire around the lawn, looking for cuts, chew marks (rodents), or places where garden tools may have damaged the cable.
• Use a wire break locator (if available): Some Ecovacs models or accessories allow measuring loop resistance or using a tone tracer to find breaks.
• Repair breaks: Cut out damaged sections and reconnect using waterproof boundary wire connectors. Bury or peg the wire back down.
• Test: Plug the station back in, confirm the boundary LED is normal, then power ON the mower and start a test run near the station.

If the boundary LED remains abnormal and E06 persists, the charging station boundary transmitter board may be defective and require replacement.
