Error code 104 on your Alfen charging station indicates an internal fault, specifically a low voltage on the internal power supply of the powerboard.
First of all, we ask you to restart your charging station.
Switch off the fuse of your charging station, wait a few minutes, and then switch it back on.
You can also do this remotely!
For a charging station at home, you can do this via the app. Read more here.
