Having a hot tub that works as it should is a great way to relax after a long day. But when there is an error or fault code, you may be left scratching your head trying to figure out what it means. Hot tub lingo can be confusing, but don’t fret. In this article, you’ll learn what many of the most common error codes mean and how to diagnose and fix the problem.

Flow & Pressure Codes

Flow Codes

Flow codes indicate that the hot tub is either not getting adequate water flow or is over-flowing. It’s important to diagnose this issue quickly so that the pump isn’t damaged by lack of water or the heater isn’t damaged by overflow.

If you get a flow code, start your diagnosis by checking the spa filter and skimmer. Both the filter and skimmer can reduce water flow and cause a flow error code to appear on your hot tub’s display. Make sure the filter has been recently cleaned and that the skimmer basket isn’t blocked with debris.

Pressure Codes

Pressure codes indicate that there is a blockage of some kind that is preventing the water from circulating in the hot tub. If you get a pressure code, first check for any blockages in the plumbing system. This could be caused by a kink in a hose or a clog in a pipe. If you don’t notice any blockages, check to make sure all the jets and valves are open.

Temperature & Heater Codes

Temperature Codes

Temperature codes are usually caused by a faulty temperature sensor. This means the hot tub isn’t getting accurate readings from the sensor and thinks the water temperature is too hot or cold. If you get a temperature code, first try disconnecting and reconnecting the power to the hot tub. This will reset the temperature sensor and often correct the issue.

If that doesn’t work, check to make sure the water temperature is within the recommended level for your hot tub. If it isn’t, adjust it to the recommended level. If nothing seems to be working, you might need to replace the temperature sensor.

Heater Codes

Heater codes are almost always caused by a lack of water flow. First make sure the flow error code has been cleared and that there is adequate water flowing in and out of the hot tub. If the water flow is adequate, check to make sure the heater has been set to the correct temperature. If all of these conditions are met, you might need to replace the heater.

Circulation & Time-Out Codes

Circulation Codes

Circulation codes usually indicate an issue with the hot tub’s circulation pump. This is the pump that circulates the water and keeps it moving around the tub. If you get a circulation code, check the circulation pump to make sure it’s running properly.

If it isn’t, you might need to replace the pump. If it is running properly, check for any blockages in the pump or plumbing system. These could be caused by debris or a kink in a hose. If the blockage is cleared, the circulation error code should go away.

Time-Out Codes

Time-out codes indicate that the hot tub’s timer has timed-out and needs to be reset. Resetting the timer should clear the error code. If resetting the timer doesn’t clear the code, you may need to replace the timer or reset the hot tub’s circuit breaker.

People Also Ask

What is the most common hot tub error code?

The most common hot tub error code is a flow code, indicating that the hot tub is either not getting adequate water flow or is over-flowing.

What does a low flow error mean?

A low flow error indicates that the hot tub is not getting enough water flow and the pump is not running properly. This can be caused by a clogged filter or skimmer basket or a kink in a hose.

What does a circulation error mean?

A circulation error code indicates an issue with the hot tub’s circulation pump. This is the pump that circulates the water and keeps it moving around the tub. Check the circulation pump to make sure it’s running properly and look for blockages in the pump or plumbing system.

What is a temperature sensor error?

A temperature sensor error is usually caused by a faulty temperature sensor. This means the hot tub isn’t getting accurate readings from the sensor and thinks the water temperature is too high or too low. Try disconnecting and reconnecting the power to the hot tub. This will reset the temperature sensor and often correct the issue.

What does a heater error mean?

A heater error is almost always caused by a lack of water flow. First make sure the flow error code has been cleared and that there is adequate water flowing in and out of the hot tub. If the water flow is adequate, check to make sure the heater has been set to the correct temperature. If not, adjust it to the correct level.

Final Words

Hot tub error codes can be confusing, but understanding what they mean and how to diagnose and fix the issue can save you time and money. Armed with this information, you should now be prepared to tackle any problems that arise in your hot tub. Good luck and happy hot tubbing!
