I followed every wire in the unit and could find nothing that looks like the flow sensor in the picture. In the Picture I posted where you can see inside the small panel the wire that come off the piece with the nut at the top when unplugged gives me the HL code which my book showed being an overheat error. On the circuit board where the last piece I posted the picture of plugs in it is labeled "in flow"

When I took a closer look I discovered the part in the picture that had a small tag on it lables "flow switch" it did not thread into the stainless pipe in any way. The flow switch just sat on the pipe with 2 small screw posts with nuts and a small plate that held it down. it appeared that one of the posts had broken off and was causing the piece to sit cock-eyed and was not flush against the pipe. I sat it on the pipe and made sure it was sitting flush and I'm still getting the FLO code.

This is the small panel below where the wiring comes in and above the heating element. I believe this is what I'm looking for.

I took the 3 filters out, and it is still giving me the FLO code. Now what it has warmed up a bit I do not think there would be any ice in the lines/pump. The jets seem to be at full flow so I believe both pumps are working properly. If it is the pressure switch where is it located and how would I go about changing it?

Hello I have an L. A. Spas Oasis tub. I work out of town and the electric had gone off while I was away and had been off long enough that aparently one of the main large pipes coming in/out of the heater unit had froze and broken the 2 piece collar. I replaced that and went over the rest of the tub and found no further damage/leaks. I turned the tub on and it went through its start up cycle, both pumps kicked on and seem to be working. Everything cycled through as normal except where it would normally display the current water temperature on the control panel it did not show anything. As soon as I tough the temperature control button to set it to my desired temperature it pops up the clde FLO on the screen.
