Possible Causes

How to Fix / Troubleshooting

Safety first: Turn off the charger’s breaker before inspecting the socket closely.

Steps:

  • Visual inspection: Check both the vehicle inlet and charger socket for bent pins, debris, or discoloration.
  • Clean contacts: Use a dry, soft brush or compressed air to remove dust. Do not use solvents or sprays.
  • Try another cable: If the problem disappears with a different cable, replace the original.
  • Check insertion force: Ensure the plug is fully inserted until it clicks. If it feels loose or wobbly, the charger’s socket contacts may be worn and should be replaced by a technician.
