How to Fix / Troubleshooting
Safety first: Turn OFF the mower before inspection.
- Check for obstructions: Inspect the right wheel for stones, branches, or wrapped grass.
- Spin test: Rotate the right wheel by hand. Compare resistance to the left wheel.
- Test run: Start a short test and see if only the left wheel moves. If so, the right drive system is at fault.
- Inspect wiring (advanced): Check the right motor connector and cable for damage or corrosion.
- Replace component: Replace the Right Drive Motor Assembly if the motor is defective. If E14 remains, the main board motor driver may be faulty.
