I Have a smartouch digital control with an ePack spa control system. I keep getting a PSoC message. I tried to loosen some of the fittings going to the pump, as I read in the manual it could be an air lock in the circ. pump. The first time I did it, the message cleared, but none of the controls would work. I killed the power a second time and flipped it back on and the message came back. Any other suggestions would be greatly appreciated. Its cold up here and I need my tub! Thanks

This thing is plumbed with a small circ pump?

The error code is simply telling you you don't have enough water pressure.

Do you have water flow into the tub?

What brought on the error to begin with?

The pump is an Advantage 5 BHP pump. There is a code on it AE 1203. I don't know much else about it. The hot tub was working fine (it came with the house I bought) and then I started having some GFCI problems. I replaced the breaker and turned it back on and got the PSoC message. The tub was drained for about 3 months during the winter because I couldnt get to the guts (too much snow) and I just recently refilled it and began trying to figure this thing out. If you need any more info about the pump or whatever I can probably find it out if I know where to look. Thanks.
