I am trying to figure out what is going on with my 1999 Marquis Destiny hot tub. I purchased this from my boss and actually saw it run and be drained for me to haul home. It is in mint condition with brand new pumps, control panel and overlays. I understand the light is on an automatic timer and kicks off after being on for one hour. Every time the light kicks off one of the pumps starts incessantly kicking from high to low every few seconds. You can push the button to turn on the light again and it runs fine again until the light goes off an hour later. Could this be the light or possibly the ozonator causing this problem?
