Im Stumped....

[SigSauer417]

Hello all,

I have never posted here and just thought I would give you all a try at helping me figure out whats going on with my hot tub....

We recently bought a house with a hot tub already in it. The hot tub was up and running when we bought it. I drained, cleaned and filled it and it ran perfect for about 2 months. One day I noticed the temp was at 100 and would not reach the 103 setting that I had it at. Thinking it was a flow issue, I changed the filter and it heated right back up and ran perfect for about 2 more weeks. It again dropped temp, but this time to 102 and would continually run at 102 and never turn off (trying to reach the 102 setting) . I bought a new filter and changed it with no luck as it still ran continually.

I did a bit of research and changed both temp probes thinking they were sending a false temp reading. After I drained it, changed the probs, re-filled it it heated up to my 103 setting and turned off.

The next day, the temp is again at 102 and runs continually trying to reach 103.

I decided to pull the filter out and see if it was again a bad filter.... it ran at 102 for 2 hours continually and never reached 103.

Im not sure what else is going on... anyone else have the same issue?

Its a 2004 Colman Maxx Spa, 631 series.

When you say temp sensor do you mean the one in the tub itself? The one that reads the temp of the body of water.

Do you own a Sig?

If there are no error codes on the display the controller may be in economy mode. Switch to standard mode and you should be set.
