I just bought a home with a j245 jacuzzi hot tub. After a few months the control panel display started blinking one number at a time. So if the temperature is at 100 degrees, only one number is displayed at a time (i.e. the 1 first, then the 0, then the second 0). There is no error code that I can find that matches this and I can't find any info through a google search. It seems as though everything is working fine. Does anyone know what this means?
