Possible Causes
How to Fix / Troubleshooting
Safety first: Disconnect mains power before cleaning contacts or moving the base.
Steps to check:
- Clean contacts: Thoroughly clean the mower and base charging contacts.
- Check base LED: Ensure the base indicates normal operation when the mower is docked.
- Test power supply: Verify the AC adapter is warm (not hot) and its LED (if present) is on.
- Battery age: Replace an old battery that may be self-discharging excessively.
When to call a technician: If a new battery still drains on the base, the charging base PCB or mower charging circuit likely needs replacement.
