I have a 04 J325 120V jucuzzi that came with the house I just bought. Continently right after I moved in the tub started throwing FL1 error. I could use some help, new to hot tubs but not new to electricity and troubleshooting. I am getting FL1 error code. Here is what I have done so far. Confirmed that flow switch works by romving and testing with a ohm meter. Circ pump is not running, but is getting voltage. Thought the pump was bad so I drained and replaced the cert pump, filled the tub and turned on, still getting a FL1 error!
Could the cert pump be air locked? How do I bleed that, the jet pump has a bleed screw but the circ pump does not. Should I just remove the discharge hose? I am worried about water getting all over everything down there... Any direction would be a great help, I am pretty competent, and I have the troubleshooting manual for assistance with volt checks.
Thanks,
Bill
