1998 cal spa hot tub won't heat up
I have a 1998 cal spa hot tub that won't heat up past 70 degrees. I took some advice on this site and have cleaned the filter and surrounding area and have checked for the heating element and for a switch- and found nothing (and I am not that savvy). To complicate matters, when I switched off the electrical box (recently installed) the clean the filter (GFI box, upgraded from old box), no electricity came back on. I checked- I have not blown a fuse or anything... Any advise? Any would be appreciated! I have had this Cal Spa for three weeks and STILL haven't been able to use it thanks to multiple issues like this one. Thank you!
