Gardena smart SILENO sense 400: No GPS signal

What this fault means

Wireless SILENO cannot establish the navigation position required for mapped mowing.

Safety: Stop the mower and follow the manufacturer safety instructions before physical inspection.

Step-by-step checks

1. Move the mower into open sky and allow positioning to stabilise.
2. Check mobile/Wi‑Fi connectivity in the smart app.
3. Confirm the charging station has not been moved since mapping.
4. Inspect recent app/firmware changes before deleting the map.
5. Persistent no-GPS state in open sky should be escalated with model and firmware.
