Check for a water leak in the electrical areas of your spa... specifically look closely around the heater terminals, look for wet and corroded connections... If this spa is wired to a plug-in outlet, look at the GFCI plug assembly as well... You can also try disconnecting the blower, pump, heater, etc, from the control pack (one at a time) to determine which item is causing the tripping.
