How to Fix / Troubleshooting

Safety first: Turn off power before opening the heater after exposure to water.

  • Dry interior: Open the cover and allow the interior to dry completely. Use a gentle warm air source if needed.
  • Inspect seals: Check door gaskets, cable glands, and conduit entries for gaps or damage. Replace or reseal as necessary.
  • Add shelter: If installed outdoors, consider adding a small roof or enclosure to protect the Elecro unit from direct rain and splashing.
  • Check for corrosion: Clean any early signs of corrosion on the PCB or terminals with appropriate contact cleaner.

Persistent moisture problems can lead to permanent PCB damage and should be corrected promptly.
