If the spa reboots to this screen after cycling the power on and off and is unresponsive you can try this to diagnose things. Your spa should have an auxiliary control panel on the opposite side of the tub. See if it will control the jet pumps and lighting. If it does, then it is likely that the main control panel will need to be replaced. If that aux panel doesn't work, the main panel could still be the issue but it may be something else that may require a service tech to check out. You can try unplugging all of the peripheral cables from the main circuit board. Peripherals would be such things as the four light cables, a salt system, music or television. Not the temperature sensors or pressure switch nor the topside and auxiliary control pads. You're trying to determine if any of the "extras" are creating interference that is keeping the circuit board from processing properly and "glitching." It's also possible the software for the system (EU 2.03. See attached) may need to be reflashed from a USB drive. The problem is usually the topside panel though. Warranty should be 5 years from date of installation. Hope this helps Mike fw(EU203) (2).hex
