How to Fix / Troubleshooting
Safety: Turn OFF power at the breaker.
- Inspect light lens: Check the main underwater light lens for cracks or leaks.
- Access light wiring: From the equipment bay, locate the low-voltage light connector on the control pack and ensure it is firmly seated.
- Check for shorts: Inspect the light cable for cuts or pinch points where it passes through the shell or cabinet.
