I can only imagine! It ran all night, should be good to go!

Got my pump installed. When i pulled the old pump i did find a piece of foam in the inlet tube near the pump. How that got past the filter i have no idea! Pulled the old pump apart, magnets still stick, no scale or residue of any sort.

Will do. Thanks guys!

So here is todays development. I jumped the flow switch terminals and restarted the tub. The circ pump ran for about 45 min until i went out and checked it. There was no flow past the flow switch and there was no fl1 error code. I turned the breaker off and back on again with no change, no flow. I left the breaker on and turned the temp up to see if the circ pump would kick in. The heater kicked on and instantly there was air in the flow switch but no real flow. Ive never seen air in it before today....and the pump never attempted to run this time.

thank you guys for the tips on this. Usually the error comes up within two hours or so. Ill turn the temperature down so the heater doesn't run while im testing it.

Is your circ pump totally stopping or does it work intermittently?

I did check the flow switch amd was getting 2.5 ohms of resistance when it was was closed and the circ pump was running. I figured it should have been 0 ohms so i replaced the switch and now have 0 ohms when the switch is closed. The intermittent magnet issue in the pump might be the problem though! I am also going to make a jumper and jump the two pins for the flow switch on the board and see if the problem comes back. If it does I guess im buying a board or a pump. Any other tests I can try on the board or the pump?

Thanks for the reply! Yes the flow switch was replaced and was installed correctly. When i reset the breaker you can see the flow fully close the flow paddle against the stand in the switch. This spa is about a 2005 i believe

I have a jacuzzi j365. Over the winter we started having an fl1 error start coming on. I have cleaned the filters, run it without the filters, topped the water off, tried forcing the "airlock" through the circ pump with a garden hose and changed out the flow switch.....to no avail. Can anyone help me figure out why i keep getting this message?

Hi all, I have a jacuzzi j365 hot tub. This morning I noticed the water was very cold, the heater had stopped working and I had an error code of fl1. I removed the filters, topped off the spa to no avail. After doing some more checking I noticed I had no flow coming from the circ pump. I checked voltage going to the pump and across the two hot leads I have 230v, yet the pump doesn't run. The only way to make the pump run is to shut the power off at the breaker and turn it on again. The pump will then run for about an hour and then throws fl1 code again. Any ideas here? Thanks!
