I have a balboa 2000 le controller in my hot tub. It has worked great for 3 years. The other day the top side contriller woun;t work and the display was jumping between mod (std-slp-eco) amd the temp of the tub. I turn the power off and on it would run through pr and go back to the same problem. cleaned filters, ran with out filters. still same thing. Can some one point me in the right direction.
