How to Fix / Troubleshooting
Safety: This is an electronic fault; blades should remain stopped while adjusting settings.
- Reset time and date: In the mower menu or Yarbo app, manually set the correct time, date, and time zone.
- Clear and recreate schedule: Delete all existing mowing schedules and create a new one from scratch.
- Firmware update: Check the Yarbo app for firmware updates that may address RTC issues.
- Power cycle: Turn the main power switch OFF for 1 minute, then ON, and verify that the time remains correct.
If E24 continues and the time resets frequently, the internal RTC circuit or backup battery on the main board may be failing.
