How to Fix / Troubleshooting

Safety first: Turn the mower OFF and disconnect from the base station. Wear gloves when working near the blade.

  • Visual inspection: Turn the mower on its side and inspect the blade motor area for signs of burning, melted plastic, or moisture.
  • Check motor cable: Follow the cable from the blade motor into the chassis. Look for cuts, crushed sections, or exposed wires. Do not operate the mower with damaged insulation.
  • Dry the unit: If the mower was recently washed or used in heavy rain, allow it to dry indoors for 24 hours before retrying.
  • Test without load: With the blade removed (following the manual), attempt to start the mower. If E11 still appears, the motor or driver is likely faulty.
  • Do not bypass fuses: Overcurrent protection is critical. If E11 persists, have the blade motor and main board tested and replaced by a professional.
