Thanks for responding. I didn't fill cube....not in the set-up instructions. However, after spending over an hour ocd-ing about it, following the instruction booklet's fixes, I unplugged the filter cube (like I should have when I removed the water
) and turned the entire cube upside-down, removed the filter, rinsed it, put it back, turned the cube back over and turned it on. Eureka! It worked!
Sometimes following the rules doesn't work and you just gotta think for yourself! lol
