Hi, I have an older coast spa, pump was just serviced last fall but during the winter the spa stopped working. I narrowed it down to the pressure switch failing, I replaced it but not when I power up the system I hear the heater engage but the pump will not kick in. I hear the relay click when I push the button but nothing from the pump. is there anyway to tell if the temperature sensor is also damaged and not letting the pump kick in? I am not even getting s basic circulation form the pump.
thanks
