Is your spa wired for 110Volt or 220V?

SOURCE: I have a 2004 great lakes hot tub with a balboa

check to see that the flow switch is working properly, it may not have enough flow on low speed to allow the heater to turn on. Make sure your filter/s is/are clean. If you have a pressure switch instead of a flow switch, it may need to be adjusted or replaced.

YOU CAN RESET THE PANEL ON SOME HEATERS HOWEVER WHATS GOING ON IS ONE OF THE FOLLOWING TWO POSSIBLITIES:
TEMP SENSOR IS DEFECTIVE (VERY COMMON)
OR
TEMP SENSOR IS TOO FAR FROM HEATER DEPENDING ON YOUR SET UP IT COULD NOT BE BE SENDING IN-ACCURATE READINGS TO HEATER BECAUSE IT IS FATHER AWAY, THE FATHER AWAY THE COOLER IT BECOMES, SO THE HEATER KEEPS RUNNING UNTIL IT THINKS ITS REACH 140 WHEN REALLY ITS 109
THE WAY TO TELL THE DIFF IS SIMPLE
IF THIS PROBLEM HAS BEEN GOING ON SINCE INSTALL ITS OPTION 2
IF THIS THIS JUST STARTED ITS YOUR TEMP SENSOR THAT NEEDS REPLACEMENT
