To help you understand and address these problems effectively, this post will delve into the world of hot tub error codes. By decoding these codes and providing troubleshooting tips, you’ll be better equipped to keep your hot tub running smoothly and enjoy uninterrupted relaxation.

Understanding Hot Tub Error Codes

Hot tubs are equipped with advanced control systems that monitor various components and functions. When something goes wrong, the control panel displays an error code to indicate the specific issue. These error codes can vary between manufacturers, but they typically consist of a series of letters or numbers that represent a specific problem, though some hot tubs also use a variety of flashing lights or dots as error messages.

Hot Tub Error Code FLO

Other variations include LF, FL, FL1, or three flashing dots

Probable Cause: Low Flow

Recommended Actions:

  • Check that your filters are clean and in a fair condition.
  • See if the circulation pump is still moving the water around when calling for heat.
  • Make sure that there is enough water in the hot tub.
  • If you have a pressure switch it may need adjusting.

Hot Tub Error Code OHH

Other variations include OH, HFL, DY, DRY

Probable Cause: Heater Dry or Overheat

Hot Tub Error Code SN

Other variations include SNT, SNH, SNS, S1, S2

Probable Cause: More often than not, sensor errors are down to sensor failure; however, they can also be a problem with the PCB.

Recommended Actions:

  • Is this caused by Tripping Electrics?
    • When does it trip, is there a set pattern? If your spa trips when you press a particular button it is usually the component you are trying to operate.
    • Check to see if the spa trips when the heat indicator comes on as this may indicate a problem with the heater.
  • Is the Spa Leaking?
    • Sensor errors can also be caused by leaks, so check how much water it is losing over 24hrs or a week.
    • Remove the inspection panel to see where it is coming from.
    • Check that all of the unions are tight.
