Open Question

FLC Code on Hot tub comes back after a few hours after reset.

I have have had a FLC code come up on our Hot Tub. The pump was making a racket, so I have replaced it to ensure there were no flow issues because of it. To reset the pressure switch I remove the pressure switch wiring from the electrical board itself, wait a minute and the code then shows FLO on the tub. Once I plug the wiring back into the board, the tub then shows the temp, the heater comes on, and everything seems fine. A couple of hours later, or when the tub comes up to temp, the FLC code comes back. Again it works over and over by resetting, but I want to fix the issue permanantly so I don't have to unplug and reset the pressure switch to get the tub to stay heated. Do I have a bad pressure switch? Are there other possiblities?

It is very easy to trace an air switch...go to the control panel and find where the air switches connect. put it in a cup of water and start pressing switches to see which one is which (bubbles). Make sure that they are dry before you reconnect them. Try switching the air hoses and then pressing the corresponding switch to turn on a function.

SOURCE: I have a flo-master 06620390-2 pump that failed.

You are generally better off replacing the pump with the same model. Hot tubs are noisy unless you have a really good insulation job. It is unlikely changing the pump will make it any different as far as noise goes. The flip side is that the manufacturer sized the pump to match the hydraulic load present within your specific tub and to provide the necessary flow rate to keep the water clean. It can lead to problems if you put in the wrong replacement unit.

SOURCE: My hot tub pump is getting loud. And if placed on

It sounds like the bearings have gone bad in the jet pump. A shaft seal leak will sometimes let water get into the bearings and the motor will get louder and louder. Running it on high can intensify the noise and heat created by bad bearings. Eventually, the bearings will seize and the motor will try to turn and since it can't, it will get really hot. The motor has built in high limits to keep from burning up completely but it will smell like it's burning. I would replace the pump motor and seal, should take care of the problem. The OH may have been caused by the pump not moving enough water to run the heater and tripped the heaters high temp sensor. I hope this helps.

check to see that the flow switch is working properly, it may not have enough flow on low speed to allow the heater to turn on. Make sure your filter/s is/are clean. If you have a pressure switch instead of a flow switch, it may need to be adjusted or replaced.

Hot tub pump will not start back up after cleaning hot tub


When you say the pump won't start back up, do you mean the electrical side of things and there is just no power going to the pump. Or are you saying that the pump is on but not pumping water.

I am going to think you mean the pump is on but not moving water. This is common after you clean and drain your hot tub. You have what is referred to as an airlock in your hot tub line. It is easy to remove the airlock by simply opening one of the unions near the pump. This will allow the air to release and water flow to begin again.

Make sure also that you have cleaned the hot tub filters, if they are dirty and reduce water flow that could shutdown your hot tub pump as well.

If it is the electrical side of things make sure your GFCI has not tripped and maybe you just need to reset this. If it is anything further on the electrical side make sure you involve a professional.

  • open a union to release any airlocks.
  • clean your hot tub filters.
  • check to make sure your GFCI is not tripped.

My hot tub is not coming on at all and is giving me a Pr code. What can I do?


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

Hello, and thanks for the question. Your error code is actually "SN" not "5N" but they are sometimes difficult to discern on the LCD topside display. The SN error code is for a Non-functional High temperature sensor which automatically kicks the heater off and trips the breaker. You can purchase new sensors for $75-$85 (it could be more, my pricing index is quite a few years out of date) I'm not sure where the sensor is located in that particular tub, although it is most likely in the heating canister. Make sure the power is off at the breaker before attempting any tub repair. if you have shut-off valves to the heating canister you may not have to drain the tub, remove the heating can and replace the sensor you will have to plug/unplug the sensors from the power pack/circuit board. I hope this helps =)

Will a flow switch stop the tub of any operation


Is the board getting power, is the control lighting up?
Do you see any error codes on the top side control?
Improper flow will give you an error code, caused by flow issues or a faulty flow switch. Make sure all gate valves are open and the water can flow freely.
If not then check your Hi Limit sensor. This is the overheat safety sensor if it fails the tub will not function at all.

What does FL mean on my hot tub?? water doesnt circulate but is still sort of warm...


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.

You should start with checking all your breakers to be sure the breaker did not pop just half of your breaker. This is something you should do with all your breakers. When you do this you should shut down all your 220v breakers so you don't get bleed back through the system. Other than that you need to look for resets on the tub. The heater is a good place to start and don't forget the gfci's on the tub or in the bath or laundry room.
