How to Fix / Troubleshooting
Safety first: Moisture inside an EVSE can cause arcing and shock. Turn off power immediately.
- De‑energize: Switch off the upstream breaker and do not use the charger until it has been inspected.
- External check: Look for cracks, missing screws, or loose glands where cables enter the Webasto unit.
- Drying: A technician should open the housing in a dry environment, carefully dry internal components, and assess for corrosion or damage.
- Restore sealing: Replace damaged gaskets, glands, or the enclosure cover with Webasto-approved parts and ensure correct torque on all fasteners.
