How to Fix / Troubleshooting
Safety first: Do not operate the heater with water inside the electrical compartment. Turn off power before inspection.
- Inspect gaskets: Check the control panel door and top cover gaskets for cracks or gaps. Replace if deteriorated.
- Seal openings: Ensure all conduit entries are sealed with appropriate fittings and that unused knockouts are closed.
- Dry components: Gently dry wet boards and connectors with a low‑heat source and allow time before re‑energizing.
- Relocate spray sources: Adjust sprinklers or water features so they do not spray directly on the heater.
