Possible Causes
Faulty gyroscope sensor, Loose sensor module, Firmware calibration error, Strong magnetic interference nearby
How to Fix / Troubleshooting
Safety: Turn OFF the mower and place it on a stable, level surface.
- Remove interference: Ensure there are no large speakers, transformers, or strong magnets near the charging station or mowing area.
- Reboot and recalibrate: Power ON and, if the Makita model supports it, run a sensor calibration or factory reset from the menu.
- Internal check: If you can open the housing, verify the gyro/orientation module is firmly mounted and its connector is secure.
- Test: After reset, run a short mowing cycle and observe for recurrence.
Persistent E17 indicates a failing gyro/orientation sensor module or main PCB, which should be replaced by a service technician.
