As you all know I got my new tub On Thursday. Got it hooked up and tested GFCI and it did what it was supposed to do. All was well. No tripping or anything from operation, tub went through its entire boot sequence. My hose water was 77 degrees from the start and I began to heat it at around 1:14pm on Friday. By 3:30 it was about 88 degrees and by 6pm it was 97 heating like a champ. Thats where it stopped, I walked out to look at 8:30 2 hours after my last check and it was still 97 and the heater indicator and circ pump still on. Since Friday evening it has only risen from 97 to 100 degrees. I went through the filter mode and heat mode and its supposed to filter 8 hours a day and the heater is set to auto, which means its supposed to keep the desired temperature. My initial temp I have set is 102. But the circulation pump continued to run and has been running since Friday afternoon and only shut off when I lowered the temperature before. Everything else works perfectly on the tub. The lights, pumps and controls etc...
What I have done to possibly troubleshoot
-I lowered the temperature to under current tub temp and the heater symbol disappears and the circulation pump soon follows. I raise the temp and the heater logo re-appears and then the circulation pump comes back on.
I had the install team set up for 60AMP logic and when i turn both pumps on the heater remains on or so the control panel symbol is there.
I also checked the circuit board connections to the flow sensors and water temp sensors and they are secured.
The only thing I haven't attempted yet was removing the filters to see if there is some obstruction, but don't understand how that could be since the tub is literally 48 hours old.
My only thinking is that I have a defective heater or something wrong with the heating unit. I guess I will be calling a Jacuzzi technician sometime Monday. Just hope because its so new they will waive a dispatch fee.
