Possible Causes

Failed LED driver on front panel PCB, Loose ribbon cable between HMI and main board, Moisture damage to display, Aging LEDs

How to Fix / Troubleshooting

Safety first: The HMI is low voltage but inside a high‑voltage enclosure. Only qualified persons should open the unit.

  • Power cycle: Turn the breaker OFF for 2 minutes, then ON to reset the HMI.
  • Check via app: Use the VW wallbox app to confirm status and errors if the front indicators are unreliable.

If indicators remain faulty, the front panel/HMI module or its cable likely needs replacement. Charging can often continue safely if all other functions are normal, but diagnosis by a technician is recommended.
