Charger shows E13 and LEDs flash rapidly; unit may have been exposed to water or installed outdoors without adequate protection.

Safety first: If you suspect water inside the charger, turn off power at the breaker immediately. Do not open the unit while it is energized.

• 1. External inspection:
  • Look for visible cracks, gaps, or missing screws on the housing.
  • Check the cable entry point and wall mounting area for signs of water trails or rust.
• 2. Drying procedure:
  • With power disconnected, remove the charger from the wall if necessary and open the housing.
  • Gently blot any visible moisture with lint-free cloths.
  • Allow the unit to air dry in a warm, dry location for at least 24–48 hours. Do not use direct heat guns on plastic parts.
• 3. Inspect seals and gaskets:
  • Check the perimeter gasket and cable gland for cracks or compression set.
  • Replace damaged gaskets or glands to restore the IP rating.
• 4. Reassemble and test:
  • Once fully dry, reassemble the housing carefully, ensuring all screws are tight and seals are properly seated.
  • Restore power and check if E13 clears.

If E13 returns or corrosion is visible on the boards, the main control board or entire charger may need replacement. Consider relocating or adding a weather shield if installed outdoors.
