- I’m getting an error on my heater “EO5” If I shut the Heater off and turn it back on the heater works. The error message usually appears when I turn on the Spa through my mobile app. and if I then go to the Heater Unit and shut it off and then push the “Spa On” button the heater works. On a few occasions the heater has stopped heater and the error message shows up right away again but most times it keeps working. Also on a few occasions it has just randomly shut off and the error message shows up.
Please provide suggestions on how I can fix it.
