How to Fix / Troubleshooting

Safety: Moisture inside an EV charger is dangerous. Do not operate the unit until it is completely dry and inspected.

  • Immediately disconnect: Unplug from mains and vehicle.
  • Drying: Move the charger to a dry, warm, well-ventilated area. Allow at least 48 hours for drying. Do not use direct heat sources like heaters or hair dryers.
  • Inspect seals and glands: Check around cable entries and housing joints for visible gaps or cracks.
