So about 2 weeks ago I started having the following problem...
I have a 2004 Sundance Altamar inside my house, running dichlor.
My circ pump is set to run 24 hours a day, I keep it in 'standard' mode and I keep the water temp set at 100 degrees.
My filter cycle runs 4 times a day for 30 minutes each time.
Now my issue, recently I have been going to use the hottub and it is NOT up to temp, and on the display I see flashing 'FLO'. So looking into the manual it says that 'FLO' means there is a problem with the circulation pump or something I think.. when the 'FLO' is flashing the heater is NOT on so the water does NOT stay up to temp.
Now, the ONLY way to get the heater to turn on is by turning on Jet #1... as soon as I turn on Jet #1 then the heater icon comes lite and I can feel hot water coming into the tub from the heater. When the Jet #1 is on, the display does NOT show 'FLO' anymore.
So how do I go about fixing this? is there a way to reset the tub computer such as disconnecting power for a certain amount of time, etc.? I don't see why all of a sudden this 'FLO' problem would have started happening anyhow? my tub is inside and always has been, never had any issues.

Buy a new filter would be my guess!! Remove the circ pump filter completly and see if it comes on my guess is it will.
-
which filter are you talking about? I only have the filter under the lid on the hottub.. it's a 2-piece filter, one side is pleated and the other side is like a foam filter.
But I don't think these are the filters that would affect the circ pump right? if no, is there another filter someplace like behind the wooden panel that I need to remove to get to?

pull your filter, see if the flo goes away, if it does it is time to replace the filter, both parts,,,, if that does not change the FLO code , it could be your pressure switch, most likely a reed style, you should be able to see it , it is clear, you may have junk on it,,,, if not possibly issue with circ pump.....

okay... where do I find the pressure switch?
also, another thing I noticed is that sometimes the tube goes into overheat mode and flashes "OH"... and the set temp is only within 2 degrees of the current temp... and when the 'OH' is flashing it seems that my heater stays running and then the water gets SUPER HOT... so I have to disconnect the breaker from the electrical box to totally shut down the tub for some time to let the water cool back down...

pressure switch is located in the equipment area, pretty much hits you right in the face, it looks like a t . its clear with a little flapper inside of it...i would check the filter.......

I had the FLO come on my Jacuzzi J-470 after a fresh fill and it was an air pocket. I had one a while back and I bought a new filter and it went away.

You have a bad circulation pump. If the flow switch was bad, it would not correct itself when the 2 speed pump is on.
