Thanks in advance to anyone's input into this issue.
I have a 5 year old Jacuzzi J-340. Earlier this year, the circulation pump started sounding like it was grinding up rocks and I eventually replaced it with another new Laing pump. Several months later, the pump is again making quite a racket.
Could the noise be air that is trapped in the pump? Do you need to "prime" these pumps once they are installed? Or could it be that I just received a bad pump. For what it's worth, I have definately isolated the noise to be coming from the pump. ABout a week ago, I was out of town for several day and when I came back and checked the tub, the temp had dropped 12-15 degrees and the pump was not running at all. I powered down the spa using the GFI and when it came back on, an F-1 error was showing on the display. AFter several minutes, the situation resolved itself and the temp came back up to where it should be, and I could hear the circ pump running again.
Can anyone give me your thoughts on this issue.
Cheers,
mike
