My Saluspa has been working fine until yesterday when it turned itself off. I turn it off and on by unplugging it and also by cycling the GFI switch. We turned on the display panel lights up for a few seconds and then dims and only shows the water temp. in Celsius(I had it set to farenhite). The lock/unlock button will not respond and all other lights are off. Any ideas for what the problem might be and solutions?
