I replaced the circulation pump and now I have circulation but the red and green lights still flash. When I turn on the hot tub the the heater light on the main board lights up of for a millisecond and then goes out, a minute later the panel lights flash.
I jumped the wires to the pressure switch connection on the main board and I have the same results.
This is the 3rd time this has happened...... I checked the voltage at the outlet and it reads 122.6 volts
Could it be another faulty board?
