I can' change the mode [its stuck on economy mode] and i can't turn on the jets either low speed or high speed .The light and air buttons still work. Also the tub is going through its timer cycle correctly, the low speed pump comes on and circulates properly and heats to the set temperature. I bought this tub used but with a new circuit board. Worked great for two months. The question is how do you know if its the topside control panel or circuit board without buying them because they are yours after you purchace them. Also is there anyway to jumper the high speed side of the pump so it will come on and wire in a toggle switch to turn it off and on when you want without damamging the circuit board or logic. If possible I think this could work since its cycling and heating fine. Thanks for any help or advice.
