Possible Causes

Mower colliding with solid object at speed, Mis‑laid boundary wire too close to walls, Damaged impact sensor on chassis, Loose internal mounting of sensor

How to Fix / Troubleshooting

Safety first: Turn OFF the mower and inspect the area where the error occurred.

  • Check boundary layout: Ensure the boundary wire is laid at the recommended distance from walls, trees, and steps so the mower slows before contact.
  • Inspect chassis: Look for cracks, bent plastic, or loose internal components that could cause false impact readings.
  • Test operation: Move the mower to an open area and restart. If E16 appears immediately, the internal impact sensor or its mounting may be damaged.
  • Repair: Replacement of the impact sensor or chassis components may be required if physical damage is found.
