Okay guys heres my problem. I have a 2000 catalina spas cat 100 and for some reason 2 days ago the tub started to run the low speed jets all the time. I can switch between high and low jets no problem but when i go to switch the jets off it turns on low speed jets after 2 seconds. The tub heats fine and shuts off heat when up to temp. I do not have a circulation pump only a 2 speed jet. I tried changing filter cycle to 8 hours but with no change. If i power off the tub it will work normally for 30 seconds and the go back to low speed jets. I know low speed on the tub turns on to heat water, but kt always used to stop the jets once up to temp. Please help me out!
