How to Fix / Troubleshooting

Safety first: Turn OFF the mower and remove the battery if user-removable. Do not open sealed electronics if this voids warranty.

  • Power reset: Leave the mower powered off for several minutes, then power ON and observe behavior.
  • Check for moisture: Inspect the housing for signs of water ingress. If the mower was recently washed or rained on, allow it to dry indoors for 24–48 hours.
  • Update firmware (if supported): Use the Greenworks app or service tool to check for and install firmware updates.
  • Avoid harsh environments: Do not operate the mower in heavy rain or standing water.

If E019 continues, the main control board is likely defective and should be replaced by an authorized service center.
