Jacuzzi Jim:
 Do you see water flowing through the flow switch?   Do you have a volt meter?  And when you say air blower, do you mean the little holes in the seats blowing bubbles that sounds like a vacuum cleaner in reverse or the jets? 

  The circ pump is like the heart of a hot tub.  If it's not running, it's not going to heat or run in many cases. 

SerjicalStrike:
What board is in there?  Which software version does it have?
When the bubble are on, is the icon on? 
When you try to turn the 1 speed pump on, does the icon come on?

PAhottub:
I can't answer the first 2 off the top of my head. Can I read that info off the board? I can check tonight. When the bubbles are on there is no icon on. When I push the button for the 1 speed pump no the icon does not come on.

SerjicalStrike:
No icon means they are not supposed to be running. So when you try to turn the 1 speed pump on, the board is not registering that you are attempting to turn it on.  That problem can usually be corrected by disconnecting the auxiliary touch pad.  Turn the power off, unplug the ribbon cable from the auxiliary touch pad, and turn the power back on.  You should now be able to turn the 1 speed pump on.

Depending on the board, you may either have a bad triac or a bad blower relay causing the blower to come on all the time, or they were plugged into the wrong spot on the board.

On the circuit board there is a chip about 3/4 of the way up, near the middle, that will have something like 1.28k or 1.28GX on it.  That will tell me what board you have

PAhottub:
So I fixed the circ pump / blower problem. Had the wires switched around. Plug them in correctly. Circ. pump and blower work as they should.

1 speed pump still not working I did already disconnect he aux. panel but that didn’t help.

Chip says 1.28G
