canadianguy86 Posted November 22, 2015 Report Share Posted November 22, 2015 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. Quote Link to comment Share on other sites More sharing options...
Spike454 Posted November 23, 2015 Report Share Posted November 23, 2015 I had a very similar problem with my 2005 sundance majesta that ended up being a circuit board issue . When I had mine on the standard setting, the circulation pump would just run nonstop as the tub would never reach its set temperature, and it would also get very hot. It sounds like that is what's going on, but can never be sure unless you have someone look at it. You don't notice anywhere where your feet would be that has a low flow of water coming out when you hear the buzzing from your circulation pump?

canadianguy86 Posted November 23, 2015 Author Report Share Posted November 23, 2015 No there's definitely no water going into the hot tub from the circulation pump.. I just took the pump apart and everything seems to be fine. The pump is a Laing, it's a really cool design I've never seen one like it where theres no shaft or anything.. I put it back together and put power to it directly and it turned on.. the pump obviously needs water to balance the drive mechanism. Anyways lost a lot of water and now I'm waiting for the hot tub to fill back up to see if that made any difference. Thanks for the information.

Brian VT Posted November 23, 2015 Report Share Posted November 23, 2015 I'm not familiar with that tub. Well...I'm only familiar with mine. ;-) Are there 1/4" hoses leading to the heater and circulation pump? Mine has these "bleeder" lines that, I think, help to prevent airlock. Also, did you fill the tub through the filter chamber? I've heard this also helps prevent airlocks. Quote Link to comment Share on other sites More sharing options...
