Why Do None Of The Buttons On My Spa Controller Work?Updated a year agoIf none of the functions on your spa control work, you may have inadvertently put the spa in to child safe mode. To enter child safe mode, press and hold the up and down button together for at least 3 seconds. The temperature will briefly flash once, confirming you have entered child safe mode. No function will work in this mode. To exit child safe mode, simply press and the hold the up and down buttons together for another 3 seconds. All functionality is now restored.
