Possible Causes

Damaged housing seals or gaskets, Cracked top cover, Missing or improperly seated cable grommets, Washing the mower with a hose or pressure washer

How to Fix / Troubleshooting

Safety first: Switch OFF the mower, remove the key, and disconnect from the charging station. Do not operate with visible moisture inside.

  • Dry the unit: Move the mower to a dry, warm indoor area and allow it to air dry for 24–48 hours. Do not use high heat.
  • Inspect seals: Check the top cover gasket, display seal, and cable grommets for damage or misalignment. Replace damaged seals.
  • Check for cracks: Examine the housing for cracks that could allow water entry and replace the cover if necessary.
  • Avoid hosing: Clean the mower with a brush and damp cloth only; never use a pressure washer.

If erratic behavior continues after drying, the main PCB or display module may have been damaged and require replacement.
