How to Fix / Troubleshooting

Safety: Water inside electrical equipment is dangerous. Turn off the breaker immediately and do not use the charger.

  • De‑energize and dry: With power off, remove the cover and allow the interior to dry completely. Use only gentle airflow; do not use heat guns.
  • Inspect seals: Check the perimeter gasket, cable gland, and conduit fittings for cracks, gaps, or improper installation.
  • Correct mounting: Ensure the Wall Connector is mounted plumb and flat so the enclosure seals properly.
  • Prevent future ingress: Reseal conduit entries with appropriate fittings and sealant as per Tesla's installation manual.
  • If corrosion or damage is present: Replace the Wall Connector; moisture can compromise insulation and safety.
