Why is the UV light on my spa red and not green?



A red UV light usually indicates any one of the following:

1. A blown or broken bulb

2. Malfunctioning UV power box

3. Loose wires into the UV system

On the odd occasion, the UV light can show red when the UV light intensity diminishes as the bulb gets old. This will also change the UV light to red to tell you to change the UV bulb.
