Bosch Charging Failure Without Error Code

Robot mower will not charge; the battery icon stays low even after hours in the dock.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Dirty charging contacts, Faulty charging station power supply, Damaged charging cable, Internal battery fault

Safety: Unplug the charging station from the mains before cleaning or inspection.

Clean contacts: Gently clean the charging contacts on both the mower and the dock with a dry cloth.
Check the power adapter: Verify the adapter output voltage with a multimeter and ensure it matches Bosch specifications.
Inspect the cable: Look for cuts or kinks in the low-voltage cable from the adapter to the dock.
Test with another outlet: Rule out a faulty mains socket.
If still not charging: The battery pack or charging station PCB may be defective and require replacement.
