Hello,
I have a Hawkeye Jupiter hot tub that's about 8 years old. Today I noticed the water temperature was down to 94 when it's set at 99. It was last used two days ago and everything was fine. Last weekend I drained it and put a new cover on and am waiting for a new filter as the current one is several months old. When it was warming up after filling, I noticed it kept reverting to economy mode but that seems to have fixed itself. The pump currently comes on and heating icon is lit but the control panel has 3 blinking dots on it. When I adjust the temperature, the temperature jumps several degrees in that direction...like it's on crack. Any ideas what's going on here?
