I apologize your question has not been picked up yet. I just logged on and saw the question still open.
If you still need help use REPLY.
this sounds like a watchdog error.
At any time does the circulator pump run?...not the jets but the circ pump
ok this is the issue....we need too see if the pump is gettting power and not running (bad motor) or if the pump is NOT getting power (bad board)
make sure to measure wire to wire and not wire to ground.
if any questions let me know
If you have no power to the pump when you press for the pump to come on then the relay is most likely bad on the circuit board and you would need a new board, but if power to the pump and no operation it is the pump, check all fuses as some control boxes have fuses for the pumps. Replace all fuses if in doubt. Three dots usually indicate that the thermostat and or the high limit are not calibrated and need replacing but this can also mean no water flow so yes if all else is good the board must be replaced.
