How do you know when it is time to change your Onzen Spa Boy Salt Cell / Electrode? Watch this video to find out!

If you have our Onzen Spa Boy Automated Salt Water System you will need to replace the salt cell when it wears out. Usually they will last about a year. However, you can use the indicator on the app to let you know when it is time to change it.

If you open up the app and swipe to the Onzen Spa Boy Screen, you will see a little battery icon. This battery icon is actually showing the life of the salt cell. When it is green, you are good. Yellow means that it is still working but needs to be changed. Red means that it is not working and needs to be changed.

Check out our other video on replacing the salt cell if you need instructions on how to replace it.
