Gardena Sileno: No Loop Signal
Having this problem with your Gardena Sileno? Start with the checks below before buying parts or resetting the mower.
First checks
- Check the charging-station indicator and confirm the loop/guide connectors are firmly seated.
- Inspect recent garden work, edging and joins for a damaged or disconnected cable.
- Test suspect connectors and splices before replacing mower electronics.
- If supported by your model, use a short temporary test loop to separate a lawn-wire fault from a mower/station fault.
Important: exact LED meanings, error codes and reset procedures can vary by model and firmware. Confirm your exact mower before replacing components.
What usually causes this type of problem?
Common fault areas include power or charging connections, installation/wiring, obstruction or contamination, positioning/connectivity, battery condition, or a model-specific sensor/motor fault. The exact order of checks depends on your mower model.
Find a boundary-wire cable break detector
If the checks point to a damaged perimeter or boundary cable, a signal cable tracker can help trace the wire and narrow down the location of a break before you start digging.
