How to Fix / Troubleshooting
Safety first: Turn OFF the breaker before opening a wet charger. Do not touch internal parts while wet.
- Step 1 – De-energize and dry: Turn OFF power and open the enclosure. Allow the unit to dry completely for at least 24 hours in a warm, dry environment.
- Step 2 – Identify leak path: Inspect conduit entries, cable glands, and the door gasket for gaps or damage. Check for cracks in the display window.
- Step 3 – Reseal: Replace damaged gaskets or glands and apply appropriate outdoor-rated sealant where recommended by the installation manual.
- Step 4 – Inspect for corrosion: Look for rust or white mineral deposits on terminals and the PCB. Corroded parts may need replacement.
- Step 5 – Test after drying: Once fully dry and resealed, restore power and test. If faults persist, have the charger inspected professionally.
