How to Fix / Troubleshooting
Safety first: If you suspect water inside the charger, switch off the breaker immediately and do not use the unit.
- Inspect exterior: Look for cracks, gaps around cable entries, or missing grommets.
- Check mounting: Ensure the charger is mounted vertically as specified; tilting can allow water to enter.
- Dry environment: Allow the area to dry out; do not attempt to open the charger yourself unless qualified.
A technician should open the VW wallbox, inspect for corrosion, dry and clean internal components, replace any damaged seals or housings, and test insulation resistance before returning to service.
