FL could be a code for low flow. If you have no circulation this sounds like it. If your pump runs and you have no flow you could have a problem with your pump. Or if you have the tub drained then it could be an air lock, if you open the drain valve till you get water out that should fix that. Also check to be sure the isolation valves are open under the spa. I hope this helps.

Drain the water weekly. IF you really want to dish out the money you can get an Ultraviolet sanitizer or even an ozone generator but those are made to work with chemicas like chlorine or bromine, not stand alone, also for pools. And even then you would have to manage the ph somehow and that can only be done by replacing water or some kind of acid. Chlorine tabs now a days usually take care of both trichlor being slightly acidic for such a small body of water takes care of both. If you have some kind of chlorine smell from your spa and you are not sitting right next to a chlorine floater then you have a problem with the chemical balance and is a byproduct of chloramines.

Can't find the type of probe or even a picture of it, so if you could Look for it and if it looks like the first probe then you can turn that little nut to calibrate it usually. If the second then you either need to calibrate it within the spa controls or even might need to replace it.

This sounds like your motor is going out. When they get noisy and run really hot is when they go outRodUS Parts Center

You need to make sure that it is a real GFCI and not a spark detection fault interrupter. When the pump is turned all the way up it may be causing a large spark that the SGCFI is detecting. If it is not that then there is a parasitic floating fault that is causing the issue.

If the water flow according to each pumps spec's match up and the plumbing lines up, with little or no modification, then all is good. but... remember this, if the water flow does (GPM's) not matchup, you will ever overdrive your hydraulics system causing premature leaking, or if undersized, your jet action will be diminished! you can find this information by obtaining the "Pump Curve" chart from each pump manufacturer. btw... The numbers you provided don't help much. Make and model name of each pump??

The ball bearings from your spa are from a roto head jet. Typically they are from one of the larger sized jets and they make the swivel action in the roto swirl jets function smoothly. You can determine which jet is coming apart by the loose function of the center nozzle. The jet can be removed and replaced to solve this problem. Most jets screw out but when they have deteriorated a lot, you may need plyers to take the jet out in pieces.

Your spa is in Economy mode. You have a basic Balboa Controller likely a Value Series.

please follow this steps and fix it. God bless you If the unit won't start, make sure power is on at the electrical panel or the electrical panel . Then test the pump and the motor. Check for and repair broken wires or loose or corroded terminals. If necessary, have the pump switch control tested and serviced professionally. If the jets do not work, clear a blocked water intake of hair and other particles (see below) or replace a broken jet (see below). If the water in your spa or hot tub is too hot or too cold, check to see if the high-limit reset switch has been tripped and, if needed, reset it. Adjust the thermostat setting and have the thermostat serviced if the problem persists. If necessary, test and replace a faulty heating elements

My first question would be about the outside temperature. What is the outside temperature? Hot tubs that are designed to operate on 115v only have 1.5kw heaters and if the outside temperature is below 50 deg F they tend to not keep up to 103 deg water while being used. They are also designed to not heat while the high speed pump is operating. Does it stay up to temperature on a normal basis? ROD US Parts Center

That is in your manual. Not all are the same and we do not know what you have,
