mark3 Posted August 4, 2008 Report Share Posted August 4, 2008 Three months ago I replaced my heater element and flow sensor switch on my Nordic Sport hot tub. At that time, the pin lights kept blinking and the tub seemed to recycle more than usual. This morning, the temp dropped to 90 and has remained there. Any suggestions on what might be the problem?
