Possible Causes

Worn or loose contacts in Type 2 plug, Corroded pins increasing resistance, Undersized or damaged tethered cable, Poor contact in vehicle inlet

How to Fix / Troubleshooting

Critical safety: Overheating connectors can lead to melting or fire. Stop using the charger immediately if the plug is too hot to hold.

  • 1. Stop charging: Use the app or vehicle to stop the charge, then unplug once safe.
  • 2. Inspect plug: Look for discoloration, melting, or deformation of the plastic around the pins. Any such damage means the cable must be replaced.
  • 3. Check vehicle inlet: Inspect the vehicle's charge port for similar signs of heat damage or contamination.
  • 4. Reduce current: Until inspected, if you must charge, reduce the current in the Ohme app and monitor temperature closely. This is only a temporary measure.
  • 5. Replace components: A technician should replace the tethered cable assembly if the plug contacts are worn or damaged. If the vehicle inlet is at fault, contact the vehicle dealer.
