I got a FLO error on my Jacuzzi J-385 and found that my 220v circulation pump (see photo) had suddenly stopped working. I checked the pump’s power source at the board (TB2) and discovered that only one of the pump’s two power wires (white) was getting 120 volts; and, the second power wire (black) was only getting 3 volts (see photos). Do you think it’s possible the board’s TB2/circulation pump connector is the problem…yielding only 123 volts with both connections versus the required 220 volts? Or, am I missing something else? Also, I found an empty connection terminal on the board (TB4) with a hot 120-volt output…so I’m thinking I can just move the pump’s black wire to it and fix the low voltage problem…but, I’m afraid Ill mess up something up and fry my new board—as it’s was replaced back in March, and the pump has been wired the same way (to TB2)/working fine since then.
Any suggestion/inputs would be appreciated.
Thanks, Jimbo
