Water fountain only runs when the main jet pump button is activated and shuts down when a lower jet setting is activated or when Jets are not enabled at all. Is this a circulation pump issue. The hot tub is only a year and a half old. I have tried shutting down the power to the hot tub and resetting it and this didn’t work. I will change my filter and see if that helps. I have ordered new filters as well, which should be here this next week.
