you may have a circuit board error that is not allowing you to operate the controls or the top side may need replacing.

It sounds like it is 120/240 volt and that one of the lines is not working. Try turning off the breaker and turning it on again. You may have to use a tester to see where the fault is.

What do you mean "Jump it"?Check with a meter, ACROSS both hot wires to get a reading of 220-240 volts. do not test across 1 hot and the meter lead on ground! You probably are not getting proper voltage to the hot tub. Or you may have a burned system fuse normally 20-25-or 30 amp fuse, which is found within the control box of the spa.

This means your top side control is dead, the spa will continue to operate itself in an economy/maintenance mode to prevent damage.
