What error 3111 actually means
The mower detected an Inertial Measurement Unit data fault affecting orientation and movement sensing. The code identifies the system reporting the fault, but it does not by itself confirm which component must be replaced.
The most useful owner checks concern a temporary IMU data interruption, orientation-sensor fault, or internal communication problem. Keep them external and reversible so you do not create a safety risk or remove useful diagnostic evidence.
Fix Navimow i2 AWD error 3111 step by step
- Press STOP. Make the mower safe before touching or moving it.
- Document the event. Photograph the error and note battery level, location, weather, task, and unusual sounds or movement.
- Inspect externally. Look for a temporary IMU data interruption, orientation-sensor fault, or internal communication problem.
- Follow the manufacturer sequence. Press STOP to clear the code, restart once if it remains, and contact support for a repeat fault.
- Run one short supervised test. Stay nearby and stop if operation is abnormal.
- Escalate a repeat fault. Save the serial number, firmware, app version, time, and video for support.

If it occurs once
Complete the official steps and supervise one short task. A single cleared alert may be temporary.
If it returns immediately
Stop repeated resets. An immediate recurrence points away from a one-time condition and toward a fault that needs manufacturer diagnosis.
Safety and mistakes to avoid
Turn the mower fully off before checking wheels, the underside, sensors, buttons, cables, or charging contacts. Do not open the battery pack, steering assembly, motors, ACU, IMU, or sealed electronics. Do not force wheels or steering parts.
