Changd water in hottub yesterday and noticed that it would not heat when refilled, during investigation it was noticed that a jumper wire betwen items K1 and K2 on the PCB board was burnt in half. I am thinking that this may be the reason for the heater issue but can find no info on these two items or what function they perform. Want to be surre that there is no issue with the PCB itself. Only info on the PCB I could locate was " Controller Board 850 LCD". Anyone know where I can get info onthis or a wiring diagram. Tub is a Sundance Optima, purchased in April 1997. Any information would be appreciated.
