I have an 8 year old Jacuzzi J-345. Recently I noticed that the lights on the waterfall started to flicker intermittently, where it will be set on one color (red for example) then suddenly it will flicker a bit through other colors, then maybe go back to solid red for a bit, then flicker...etc. Kind of like lighting...a quick flash here and there, and then normal for a bit. I thought it was only the waterfall lights, and thought about tearing apart the waterfall, but last night I noticed it's the light behind the head pillows too, and it's all flickering at once in unison. Interestingly enough the lights at the cup holders is not flickering...they are staying on whatever color is set. I have no idea where to begin troubleshooting this? Anyone experienced this, and/or have ideas where to start?
