Prof Paddle Posted March 20, 2017 Report Posted March 20, 2017 My hot tub is 3 years old and has a ClearRay UV sanitizer system installed. I have changed the UV bulb once, about 8 months ago. When the filtration pump is running then the ClearRay system signals that is working by illuminating two indicator lights. Both of the lights are out and I am wondering how I should start troubleshooting the system. Thanks in advance. Quote
