sounds like the pump is stuck, it is trying to rotate but can't.
try whacking it with a spanner, hard but not too hard.
you can check if it is rotating by removing the screw in the middle, you will have a little bit of water, but not much, won't even fill a glass.
if you take of the screw completely, insert a screwdriver in it, you will notice if it is running or not. just don't jam it hard in there.
