How to Fix / Troubleshooting
Safety first: Turn off the robot and remove it from the dock.
- Power cycle and reset: Perform a full power cycle and, if available, a factory reset via the app or buttons.
- Check for obvious damage: Inspect the exterior for cracks or signs of liquid ingress that may have affected internal wiring.
- Update firmware: Use the app to ensure the robot is running the latest firmware.
- If E19 remains: Internal diagnostics indicate a communication problem between the main board and one or more sensors. Professional disassembly is required to inspect and reseat sensor harnesses or replace the main control board.
