Question i recently aquired a 2002 sundance camrio spa when i purchased a home. It was empty when i bought the house. I was able to fill the spa up and get everything working so i thought. The spa heated the water and it appeared all the jets were working properly. I was going to get in it for the firt time a day later and i saw "OH" on the control panel. i looked up the error code on line and saw that the water was too hot but when i felt the water it did not appear to be too hot at all. i tried to turn the jets on but nothing would work so i turned off the breaker and turned it back on the next day. Everything seems to work for a short time then i got this, "--d" on the control panel. The water was warm but not hot. I know nothing about spas and have not been able to find any type of error code "--d" any help would be appreciated.
