What does oh mean on a hot tub

Many hot tubs come equipped with a display panel that shows the current temperature and various error codes or messages that may appear when something is not working correctly. For example, one code that may appear on your hot tub display is “OH,” which can be confusing if you’re not sure what it means. In this article, we’ll explore what “OH” means in a hot tub and what you can do to fix any issues causing it.

What Does “OH” Mean on a Hot Tub Display?

“OH” stands for “overheat,” and it means that the water in your hot tub is too hot. The specific temperature at which this code will appear will vary depending on the make and model of your hot tub, but it is typically around 104-108 degrees Fahrenheit.

What Causes the “OH” Error Code?

There are a few different things that could cause the “OH” error code to appear on your hot tub’s display:

  • The thermostat is not working correctly: The thermostat is responsible for regulating the water temperature in your hot tub. If it is not functioning properly, it may cause the water to become too hot and trigger the “OH” error code.
  • The heater is malfunctioning: If the heater in your hot tub is not working correctly, it can cause the water to become too hot and trigger the “OH” error code.
  • The circulation pump is not working correctly: It is responsible for circulating the water in your hot tub, which helps keep it at a consistent temperature. If the circulation pump is not working correctly, it can cause the water to become too hot and trigger the “OH” error code.

What Should You Do if You See the “OH” Error Code?

If you see the “OH” error code on your hot tub’s display, here are a few steps you can take to try and fix the issue:

  • Check the thermostat: If you suspect it is causing the “OH” error code, try adjusting it to a lower temperature. If the error code persists, it may be time to replace the thermostat.
  • Check the heater: If you suspect it is causing the “OH” error code, try turning it off and back on again. If the error code persists, it may be time to replace the heater.
  • Check the circulation pump: If you suspect it is causing the “OH” error code, try turning it off and back on again. If the error code persists, it may be time to replace the pump.

It’s also a good idea to check the filters and ensure they are clean, as dirty filters can cause issues with your hot tub’s circulation and temperature control.
