I have a 2015 Sundance Optima hot tub with a light problem. All lights seem to be working but when we cycle the colors, the reds are gone (no pink, purple, etc. Anything that might use the red spectrum for color). Foot well lights show red, but nothing at the waterfall or jet controls. I understand there is a light bar under the waterfall that generates and controls the colors. However I've been unable to locate a parts diagram or find out what part I may need to order to fix this.
Any help or pointers appreciated.
