Automower EPOS No Correction Data: Positioning Checks
Automower NERA/EPOS showing No correction data? Check correction source, satellite view, connectivity and installation before remapping.
Quick answer
EPOS faults are positioning-system faults, not boundary-wire faults. Confirm which correction source and installation your mower is using before changing the map.
Check these in order
- Confirm the mower is actually configured for EPOS/wire-free operation.
- Check sky view around mower and docking point.
- Confirm reference/network correction service is available for your setup.
- Update app/firmware using manufacturer-supported methods.
- Avoid deleting a good map until positioning has been checked.
Safety: Switch off and isolate the mower before touching blades, exposed wiring, charging contacts or internal components. Do not bypass safety systems.
What the symptom tells you
The useful question is not just “which part could be bad?” but where in the system the failure begins. Record the exact message, LED/status indicators and whether the problem happens everywhere or only in one part of the lawn. That evidence helps separate installation, positioning, charging, connectivity and mower-hardware causes.
If a basic check does not clearly identify the cause, avoid replacing multiple parts by trial and error. Use the guided MowerFix AI diagnosis or a qualified dealer for internal electrical and safety-critical work.
