thanks for the help!
Ill check for tightness but pretty sure its tight. SO what's bets option and how do I ensure this doesn't happen again?
This hot tub did get flooded last year , which is why I replaced circuit board, controller, and pump. The heater did not get replaced. Is there anything that could be bad on actual heater from the flood that is causing this? Everything has functioned perfect for the last year
Should I look into spaguts and swap out the unit?
