How to Fix / Troubleshooting
Safety: Disconnect the charger from mains before inspecting. Do not open the battery pack casing.
- Check charger output: Use a multimeter to verify the Siemens charger outputs the rated voltage. If there is no output, replace the charger.
- Inspect contacts: Clean the charging contacts on both the cleaner and the charger with a dry cloth. Ensure there is no corrosion or debris.
- Allow battery to cool: If the pack is warm, let it cool to room temperature and then attempt charging again.
- Try a different outlet: Plug the charger directly into a wall outlet, avoiding extension cords.
If the battery still does not charge or the error persists, the battery pack or internal charging PCB may need replacement. Lithium-ion battery service should be performed by an authorized Siemens technician.
