Possible Causes
Failed real‑time clock (RTC) circuit on main PCB, Depleted backup battery or supercapacitor, Firmware bug affecting schedule storage
How to Fix / Troubleshooting
Safety first: No disassembly is required for basic troubleshooting.
- 1. Re‑enter settings: Set the correct time and date in the SilverCrest app or on the robot. Recreate cleaning schedules.
- 2. Keep on dock: Leave the robot on the charging dock continuously for 24 hours to recharge any internal backup capacitor.
- 3. Firmware update: Check for and install any firmware updates that may address scheduling or memory issues.
- 4. Observe behavior: If the robot still loses time and schedules every time it is powered off, the RTC or backup circuit on the main PCB is likely faulty.
- 5. Board replacement: Replace the SilverCrest main control board if E19 persists and scheduling is critical.
