Turns out my off-brand (Coral Box) was super easy to open - case has screws instead of rivets. BUT... as luck would have it, the fuse was blown! Cheap fix, if that's all it was.
@fishy408 Question: is your backup still warm/hot to the touch at all times? Mine is. I have an old version and a new one. They also smell a bit like chlorine, maybe how you described a smell like rubber.
Maybe I need to look up EcoTech's setup, but my enclosed instructions are confusing and I already looked it up online. Do you have your backup power supply and your pump power supply plugged in at all times?
