Hot tub keeps running all night keeping me awake. How do you shut it off? It's a Great Lakes.


If the system is the Jacuzzi 52221-05 system mentioned in the subject header, there could be a stuck relay causing the problem and you might need to get a spa technician out to assist you in repairing the problem. However...

If it is a Great Lakes system as mentioned in your message body, then there could be a programming issue allowing the filter cycle to run continuously. Provide a model number off of the Balboa control. Then we can provide you an instruction manual or reference card to assist you in resolving this problem. you can also search our online manuals at our website. You can find them online at:

We have a Great Lakes spa with a Balboa control panel, manufactured in 1992. When you plug the spa in, it will shut down and read Sn on the topside control panel. We have replaced the high limit/temp...


Contact Balboa's Customer support department directly at 800-645-3201, follow the prompts to customer tech support (or press 0 and ask for customer support). You will need to be at the spa, control panel open and ready to read off the chip number, and you will need to be proficient with a test meter (AC voltage). The SN error is related to a bad sensor(s), but can also indicate a failed board. An incorrect sensor set will also create this problem, so confirm you used the exact or compatible replacement. If the SN code issue is no longer a problem, but the spa is still not heating, look and see if the heater led is on. If it is, you likely have some burned relays on the board, which can be replaced cheaper than replacing the board. If you need more help, email me at info@coastsideservices.com

Error code reads "5n" or "Sn" on the panel. Great lakes hot tub. chuck


'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.

I have a dream maker and my heater will not turn on. I had this problem once before when I drained it. However I cannot get the SN error code to go away. Any help would be great


Dream Makers do not have traditonal heaters. You may have an airlock. Look for a plug on top of the pump or some part of the plumbing, loosen to let the air out.

When I put power to my unit. A Sn code appears. Great Lakes spa 1996 260E balboa wiring


If the SnS or Sn Message is Alternating with the Water Temperature on the Display, it is a Possible Sensors Out of Sync Message.
If the SnS or Sn Message is Blinking or Flashing OFF and ON without showing Water Temperature, it is a Verified Sensors Out of Sync Message.
