We have experienced a list of problems with this spa. We have replaced the top side and today the circuit board. The display reads 145 degrees. Drop in thermometer reads a nice 103. We press the Jets button, nothing. The indicator light is one, but no jet or air, for that matter. Any thoughts?

We have replaced thermostat twice in 2 years. It had new pumps installed 3 years ago. Any thoughts?

Turn off the power for at least 30 minutes, this should give ANY system a full reset, if the temperature display shows 145 immediately upon power up then there is definetely a problem with the temperature sensor and therefore the sensor will most likely have to be replaced, if the temp shows normal and proceeds to rapidly climb it could be a relay problem on the circuit board causing the heater to activate pre-maturely or possibly even an Air lock caught somewhere in the heater.
