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.

SOURCE: Error code reads

'Sn' is a general error message relating to the temperature sensors.

Assuming that you have a Balboa spa pack (M7 version), turn off the power and remove the spa pack cover, you'll find two temperature sensors mounted in the top of the heater tube one at each end. Follow the wiring from the sensor to the plug(s) on the PCB and check that the connections are good, they have a habit of devekoping a poor connection.

If you have a multimeter you could also check the resistance of the two sensors. They should both be the same. If they aren't the same you'll probably have to replace them.

One final thing just to check... Ensure that there are no blockages within the heater. Unless you have service/gate valves you will have to drain the hot tub, unscrew the unions and check inside the heater for debris within the heater assembly.

If you're from the UK I may be able to help regarding parts etc.

Kind Regards,
Ian.

Great lakes hot tub


Normally f2 is not an error code.
It is informing you that you are in a "Filtration" mode. In this case Filter Mode #2
But, if we knew what make & model of the control system you have, will assist us better in helping you. Spa manufacturers normally do not use their own proprietary control systems. They will use a 3rd party vendors unit & install them on their spa.

F2 error code


An F2 error code means usually that you have a flow issue in your hot tub or you have a part malfunction. The best thing to do with an F2 error code is to go through a trouble shooting diagnosis. Start by cutting the power and letting the unit cool down and then do a reset of the equipment. If that does not fix your issue then do a water flow check, clean your filters, release air locks, remove debris from your intakes and returns. If your problem still remains look to replace or repair fuses, heater elements, or your circuit board. I hope this helps. http://www.thecoverguy.com/backyard-blast/f2-error-code-trouble-shooting/

The power went out in town, the power came back on, and the power is on to the hot tub, but we got an F2 code, and it isn't going on to cycle and the temp is at 54 now. What is the F2 code. We have a great...


I need to know what kind of control pack your tub has. If you can open the side panel and tell me what brand the pack is I can tell you what the error code is for.

I have a 2004 great lakes hot tub with a balboa controler. My hot tub heats up fine when the pump runs on high but the temp light never comes on when the pump runs in low.
