How to access Hayward Power Flo Matrix impeller?

[ChemicalBreakdown]

I have the dreaded humming pump and after reading several threads, I thought if we could spin the impeller, we may be able to free up something.
The problem is, I can't access the impeller. We have a Hayward Power Flow Matrix 1 hp that has only been used for 2 seasons. My husband took the pump apart on the wet end and you can see the impeller is behind another piece of plastic. You can see and touch the rounded end, but the blades are barely visible. I can get my finger in to touch them, but can't move them. Any suggestions?
I found a photo of the impeller for my model, an SP1510Z1XEHC, and am attempting to attach it to this post.
Thanks!

on the back end of the motor there may be a cover to remove and you can access the shaft at that end.

Thanks Bobo. We did access the other end and the impeller won't budge when trying to turn the shaft with a screwdriver. My husband also can't get the impeller off or get in from behind it to see if there is any debris in there.

Does the motor end have a nut on the shaft that you can put a wrench on? That'll give you more torque than a screwdriver. With it open like that, you can't turn the impeller at all? That whole piece should spin, not just the blades inside it. You should be able to hold the nut on the shaft, and spin the impeller counter-clockwise to unscrew it.

Looks as if the motor may have been sitting in some standing water or the seal has been leaking.
