Hey Everyone,
First off I'd like to start by saying I'm a new member on this forum and also a new hot tub owner as of last week. So here's the situation, a friend of ours gave us her old hot tub which is a 2001 Sundance Caprio. We got the hot tub home, hooked up the power, and filled it up. Everything seemed to be working fine, the jets were running the control panel lit up and there were no errors. I put the cover on and came out a few hours later to find that the temperature had only gone up a degree or two and the jets had been on most of that time.
My first thoughts were that the heater must be broken so I hooked the heater up the control panels power directly and it heated up almost instantly so I ruled out that. When inside the control box I noticed that the connection to the circuit board where the heater was coming out was black and fried. I then went online and purchased a new circuit board which will be her in a few days. Another concern I have is that I'm not sure how the circulation pump works, I can definitely here it humming but I'm not sure if it's actually running or not. The circulation pump definitely gets really hot and even heats up the water lines coming out of it. I don't see any water coming out on the inside of the hot tub, is there a dedicated jet or is it the big round thing on the side my the feet thats about 4-5 inches in diameter and has a bunch of tiny holes in it? Or maybe the pressure just isn't enough to be visible from the surface of the hot tub. Also, would the circulation pump still operate even if the heater wasn't working? Sorry, I know I have a lot of questions I just don't want to put a $250 circuit board in and then have it fry because something else was messed up originally.
I've read a lot of forums and topics based on the Sundance Caprio and it seems this is a common problem for the circuit board to go after 10+ years. Thanks for any help or insight anyone could give into my situation.
