What matters on the Automower 305E NERA
This NERA model may be installed with a physical boundary wire or, where supported/configured, a wire-free EPOS setup. The correct diagnostic branch depends on the installation actually in use.
Use the exact error text shown by the mower or app. Similar wording across mower generations does not always mean the same component has failed.
Start with these checks
- Check internet/connectivity status.
- Check correction-data/reference-station path if applicable.
- Retest.
- Persistent fault → support.
- Record the exact message or behaviour before restarting the mower.
- Inspect the mower and the exact stopping area for obvious obstruction, contamination or installation issues.
Stop if: the mower has damaged wiring, a swollen/damaged battery, severe vibration, water inside electrical areas, or would require opening sealed electronics.
What this fault can mean
No correction data available. Similar symptoms can have more than one cause, so work through the checks in order rather than replacing parts immediately.
Diagnostic decision
- Connectivity restored → retest
- Still unavailable → support

Automower 305E NERA General mower fault FAQ
Can I keep mowing with this no correction data available fault?
If the mower is repeatedly stopping, vibrating, failing to charge/dock or reporting a safety-related warning, stop and diagnose the cause first. Continuing can turn a minor obstruction or installation problem into a larger repair.
Should I replace a part immediately on my Automower 305E NERA?
Do not order parts solely from the error wording. Confirm the failing system with the checks above first.
What information should I record before contacting a dealer?
Record the exact error/message, charging-station light or app status, when the fault occurs, whether it is location-specific, and any recent changes to the garden, station, map, boundary wire or mower firmware.
When should the Automower 305E NERA go to a professional repairer?
Use a dealer or qualified repairer when the fault persists after safe external checks, when sealed electronics or battery packs would need opening, when wiring/electrical testing is required, or when the manufacturer procedure calls for service.
