So I have a J315 Jacuzzi brand hot tub. A few years ago the display/controls started freaking out, flashing digits and such which I ignored and then the heater failed-just wouldn't heat.
Eventually had the local pool store come out and they replaced the control board which fixed everything.
well guess what, the controls/display are doing the same thing again...All the controls work fine but the digits for temperature flash so you only get 1 digit at a time 1.....0......3......., but everything works fine.
Sound like a control board issue again? Exact same symptoms as before....Real question is, replace the board now or ignore this minor issue and see what happens? (just don't want a repeat of last time when it failed when it was like 5 degrees outside....
