Bosch Scheduling / Real-Time Clock Issue

Robot mower does not start at scheduled times, but can be started manually.

Possible Causes

Incorrect schedule settings, Time or date not set, Firmware bug affecting the scheduler, Weak internal backup battery (if present)

Safety: No special physical risk; no need to open the mower for basic checks.

Verify time and date: Use the mower menu or app to ensure the clock and calendar are correct.
Check the schedule: Confirm that mowing days and time windows are enabled and not blocked by a "vacation" or pause mode.
Update firmware: Install the latest firmware via the app or USB if available.
If the schedule still fails: The internal RTC (real-time clock) circuit or its backup power may be faulty, requiring main board service.
