The float valve is in place just to stop the water flow from the pump in this case where the optical sensors have failed.
the pump will still run if the float if up /closed but no water will get into your sump once it's all the way up.
prevents overflowing basicly. sounds like some kind of electronic issue with the sensors, best to contact apex directly they will take care of you quickly.

good luck!
