Robot mower shows E8 and stops; may occur randomly during operation.

Safety first: Turn OFF the mower and remove the battery if possible. Work in a dry environment and avoid static discharge when touching electronics.

Steps to check:

• Visual inspection: Remove the top cover and inspect the main PCB for signs of moisture, corrosion, or burnt components.
• Drying: If moisture is present, gently dry the area with a soft cloth and allow the mower to sit in a warm, dry place for 24 hours (do not use direct heat guns).
• Reseat connectors: Carefully unplug and replug the main wiring harnesses (display, sensors, motors) one at a time to ensure solid connections.
• Firmware update: If your Worx Landroid supports app‑based firmware updates, connect via Wi‑Fi or Bluetooth and check for updates. Apply any available update following Worx instructions.
• Test: Reassemble, power ON, and run a short test cycle.

When to call a technician: Persistent E8 usually indicates a failing main board. Replacement and firmware flashing should be done by an authorized Worx service center.
