Pump basket not filling with water

If you have an above ground pool, the pump is usually below water level. Is this the case?

A bubble trapped in the lid is no big deal. They generally work their way out in a day or two, If the basket is really low and churning, you've got a restriction in the suction side.
 
I forgot to mention my filter pressure is normally 14 psi but is 24. I’m opening the pool with algae but use hairnets to capture gunk. Do you think a backwash might help? The deal is it would only fill 3/4 before I started the filtering process.
 
A clogged up hairnet could restrict the flow enough to make the pump starve.

And high pressure means a clogged filter, which doesn't help. I think the next steps are to backwash and clean the hairnet. And see how things run with the multiport valve set to bypass.
