Possible Causes
Worn or contaminated Type 2 socket contacts, Loose internal cable terminations, Undersized supply cable for configured current, Continuous operation at maximum current in high ambient temperature
How to Fix / Troubleshooting
Safety first: If the enclosure or cable is too hot to touch comfortably, stop charging immediately and turn off the charger at the consumer unit.
User steps:
- Reduce the maximum charge current in the Andersen app (e.g. from 32A to 16–20A) and monitor temperature on the next session.
- Ensure the cable is fully unwound from any storage hooks so heat can dissipate.
- Check that the Type 2 plug is fully inserted and latched.
If overheating persists even at reduced current:
- A technician should open the unit and check all terminations (supply and tethered cable) for tightness and signs of overheating.
- Inspect the Type 2 socket contacts and replace the socket or cable assembly if there is pitting or discoloration.
- Verify that the supply cable size matches the configured current and derate if necessary.
