I have a Sundance optima and all of a sudden my jets are turning on and off randomly. Today I went out and they would start for a few seconds, stop, and then start again. Right now it is running and I can't stop them with the button. I turned the breaker on and off but still nothing. My control panel is not displaying any error message. Pretty cold here this weekend so don't want to turn it off but also don't want th tub running all weekend. Any help would be appreciated
