Navimow X4 Error Code 9103: Database Reading Error
Error 9103 means the X4 encountered a problem reading its internal database, potentially affecting maps, settings, or mowing tasks. Start with a controlled reset, not a factory reset.

Quick answer
Navimow defines code 9103 as “Database Reading Error.”
Press STOP to clear the code. If it persists, restart the mower, then place it on the charging station and check again. Do not delete maps or perform a factory reset unless Navimow support specifically directs you to do so.

Follow this diagnostic sequence
- Press STOP once. See whether the code clears and remains cleared.
- Do not edit or recreate the map yet. The code identifies a database-reading problem, not proof that the lawn map itself is wrong.
- Restart the mower. Let it shut down fully before powering it back on.
- Dock it on the charging station. Confirm that the mower sits correctly and has stable power, then check whether 9103 returns.
- Escalate a persistent error. Preserve screenshots and the failure time for support rather than repeatedly resetting the unit.
Do not erase useful evidence
A factory reset or map deletion may remove information without repairing an underlying storage or software fault. Navimow’s code-specific instructions call for STOP, restart, and docking. They do not instruct owners to erase the mower.
What this code actually tells you
The mower’s internal database can contain information needed for maps, preferences, and tasks. A reading error means the system could not retrieve something it expected. The code alone does not reveal whether the interruption is temporary or whether internal service is required.
After the prescribed restart, check whether your maps and settings appear normally. Avoid starting an unsupervised task if the app shows missing or inconsistent boundary information.
How 9103 differs from a GNSS problem
Error 7106 identifies the GNSS positioning module. Error 9103 concerns reading the internal database. Both can affect navigation, but their first-line procedures and likely escalation details are different.
Before contacting Navimow support
Prepare the mower serial number, the exact date and time the error occurred, and a screenshot or video showing the message. Also note whether the mower was mowing, docking, charging, starting, or communicating with the app when the code appeared.
Frequently asked questions
No. That is not part of Navimow’s published procedure for 9103 and may remove useful information.
First confirm the expected maps and settings are visible, then use a short observed task rather than immediately resuming unattended operation.
Contact Navimow support with the serial number, exact time, and screenshots or video.
