How Navimow H2 error codes work
Segway keeps a separate error code section in its Help Center for each Navimow series, with one article per code. This page covers the Navimow H2 series: the H210 and H220. Many numbers, like 6112 or 2105, also appear on other series, but Segway writes each series its own fix, so use the list for your model.
Codes in the 1100s cover the cutting motor, 2100s the battery, 3100s the wheels, 4100s and 4300s electronics, 6100s and 6300s maps, position, docking and getting stuck, 7300s the LiDAR and camera, and 7100s to 9100s data and software faults.
The general fix sequence
Segway's articles follow the same pattern for most codes. Use it before contacting support.
- Fix the physical cause: lift the mower out if it is stuck, move it back inside the boundary, or clear the dock.
- Press STOP on the mower to clear the code.
- Resume the task in the app.
- If the code comes back, restart the mower.
- If it still comes back, contact support with the serial number, the date and time of the error, and a video if you can.
Codes that need support
Segway gives no at home fix for 8101 (camera sensor calibration) or 4301 (incompatible ACU board), so contact Navimow support for those. 2107 and 2108 mean the battery is not a genuine Navimow battery for this model. US owners can email [email protected], and the app also has Live Chat.
