Neptune auto top off failing

Whoa that sucks.

But maybe something else is awry?
I'm new to controllers and I'll tell ya there's quite the learning curve and I found it quite frustrating to figure out on my own.

For my set up, my top up reservoir (brute can) has a water level higher than my sump, so although the ATK comes with a check valve, I needed to get the solenoid to make it work properly.
