Hello. I've got an older CalSpa 2000 and it runs well during the summer, heating to 100+ degrees as needed, but the outdoor temps tended to be from 75-95 degrees. It appeared to heat well simply by having the cover on, but I noticed if I had the temp set to 100, it would drop to mid-90s even during the summer. The pump would run constantly and the heat light would never come on unless I turned the pump to high speed with the "jets" button and that only lasts about 15 minutes each time. So, I'd have to wait around and hit the jets button every so often to get it to (and keep it at) the desired temperature. During this last winter (I'm in Michigan), I could not get it to heat above 78 degrees, even while "activating" the heat with the jets on. My thought is it should heat to temperature regardless of whether the jets are on high or not. I'm not getting any errors codes and it's certainly never overheated. Underheating is my issue. How can I fix this? Thanks.
The Story behind the tub. i purchased a balboa hot tub from a spa company in my city and this tub is a 1998. when i first set everything up they forgot to send me the pump so when i called them they couldnt find it and gave me a brand new ultra jet pump. when i wired everything up the lite leader board wasnt putting out the right voltage so i had to get it replaced. once i finally had everything said and done the problem im having is the following When i wired the pump up the diagram on the lite leader showed brn blu and blk going to pump as high low and common. and the wires that i have for my pump are black red and white. so finally i found a diagram on the internet for lite leader that had those 3 colors and i wired it up. the problem im having is when i first boot up the hot tub it begins heating with the pump on low speed. which is my understanding thats how it should be but unfortunately it wont heat up the tub past 80 degrees. but when i switch the high and low wire so that it heats with the pump on high it heats the tub to 104. the issue im having is that this will use much much more electricity. Anyone have any ideas on what could be going on? Any help is appreciated it!
