For the last few months my 10-year-old Hot Spring Vanguard has been acting weird. The jets mysteriously go on and off multiple times per day. Also, the heater seems to go to the highest temperature on it's own. I'll have it set at 103 or 104, and later when I get in the water is scalding hot...this also happens on its own. Could these two issues be related to one another? Any ideas or help is greatly appreciated.
