SavyAndJoe Posted August 3, 2009 Report Share Posted August 3, 2009 Hello, I am absolutely a noob to hot tubs, but I was recently given a sundance 850 series spa, I believe to be in the early 2000s or maybe very late 90s, it seems like it's in good shape and the owner before me said it worked fine and he had recently replaced the circuit board and heater. I have wired in the new 220 line and I finally got it filled when I noticed that the sensor cable seems to be missing. and after I turned it on it displays 3 errors: Sn 1, Sn 3, and ILOC. I read up on what I think they are but honestly I think I'm in a bit over my head. Any help is welcomed. Thank you. Quote Link to comment Share on other sites More sharing options...
Peteyboy Posted August 4, 2009 Report Share Posted August 4, 2009 I wouldn't think anything of the errors until you have the sensor installed. If it's the temp sensor it should be in there somewhere - it would leak if the sensor was missing completely. Quote Link to comment Share on other sites More sharing options...
SavyAndJoe Posted August 4, 2009 Author Report Share Posted August 4, 2009 Yeah, I think I kind of figured out a couple of the sensors, but it was just the sensor harness and hi-limit sensor that were missing. Hopefully, I will have it worked out in a couple days, thank you, though, for the reply. Quote Link to comment Share on other sites More sharing options...
