jacuzzi j345 FL1 error

<< < (2/3) > >>

So I replaced the flow switch to no avail but upon closer inspection I think the circ pump is running the wrong way maybe a wrong circ pump. I will get a hold of my hot tub dealer and see which one they gave me could be any of these 3 6500-064 or -066 or -065

Jacuzzi Jim:
  Do you see water flowing through the switch with the little flapper thing hitting the post?   If not then something is wrong.

  The 6000-125 is for the Laing circ pump, Jacuzzi is now shipping a retro fit pump out because they quit carrying the Laing which might be what your dealer or whomever sold you?   Not sure the part number though.

After reading instructions a few times and finally looking at the diagram(go figure) they changed which side the output to the heater is so I think we put the pump in backwards will try it tomorrow. It looks like the flow switch flapper is going the wrong way when the circ pump is on

Jacuzzi Jim:
 Would love to see a photo of what you have, not the spa but the pump and how you have it hooked up.

thats the pump put in the exact same way as the old one was top was output side was input but according to the diagram on this one top is input and side is output so it needs to be swapped around so it pushes water through the heater
