Possible Causes
Earth leakage in Andersen internal wiring, Faulty DC leakage sensor module, Moisture ingress causing tracking to earth, EV with internal insulation fault causing DC leakage
How to Fix / Troubleshooting
Safety first: Do not repeatedly reset an RCD/DC leakage fault without investigation. Turn off the charger at the isolator.
User steps:
- Check if the upstream RCD/RCBO in the consumer unit has tripped. If so, reset once after unplugging the EV.
- Inspect the exterior of the Andersen unit for signs of water ingress, cracks, or damage.
- Try charging a different EV if available to see if the fault follows the vehicle.
If E08 persists with different vehicles:
- Internal leakage or a faulty DC sensor is likely. This requires a qualified technician.
- The technician should test insulation resistance of the charger, inspect for moisture, and verify operation of the internal DC leakage sensor/RCD module.
- Replace the DC leakage sensor module or main control PCB as specified by Andersen.
