How to Fix / Troubleshooting

Safety: Turn OFF the mower and unplug the charging station before modifying boundary wiring.

Check layout: Ensure the boundary wire is installed according to Mammotion guidelines, with required distance from metal fences and other cables.
Identify interference sources: Temporarily turn off nearby electric dog fences, irrigation controllers, or other RF/inductive systems to see if the error clears.
Re-route wire: If the boundary wire runs parallel to mains cables or metal structures, move it further away where possible.
Station check: Inspect the charging station for damage and ensure the boundary terminals are tight.
If E019 continues with a clean layout and no external sources, the station's boundary transmitter may be defective.
