Possible Causes
Failed Hall sensor in right drive motor, Damaged right motor encoder cable, Loose connector on main PCB, Internal gearbox sensor failure
How to Fix / Troubleshooting
Safety first: Turn OFF the mower and disconnect the battery before servicing the wheels.
- Inspect right wheel: Remove debris and ensure the wheel rotates freely by hand.
- Check motor wiring: Follow the right drive motor cable to the main board. Inspect for damage and reseat the connector.
- Functional test: In a flat, open area, power the mower and observe right wheel motion during start and turns. Lack of smooth motion suggests feedback issues.
- Diagnostic swap (advanced): If possible, swap left and right motor connectors at the board to see if the error changes sides, helping isolate the fault.
Persistent E17 typically indicates a defective right drive motor/gearbox assembly.
