There is a height proximity limit switch on the right side of the machine undo the covers...verify that is still mounted properly and operational
Fixed it, kind of. It seemed to be stuck up for some reason. Once I got onto the force and hit the button it went down. It was kind of sticking at first, but after going up and down a few times, it started going back down on its own just fine.
With the weight of 4 lead acid batteries and yet it wouldn't drop on its own seems strange. So the valve was clicking open and working just fine, it was just stuck up.
