Error code 201 on your Alfen charging station indicates a possible issue with the grounding. This means that the grounding of your electrical installation may be interrupted, unstable, or not properly connected.
We recommend contacting your electrician first. He can check whether the grounding of your home electrical installation is still functioning correctly (ideally with a grounding resistance of less than 100 Ohms).
If the grounding is found to be in order, please contact us via this form so that we can schedule an intervention to check your charging station.
