the pump maybe airlocked.
switch off system and remove the large centre nut and bleed the pump of air.

or try the pump on the top speed first may shift the air sometimes.

Pump can sound as though it is running but not be circulating.

Have you looked for any air bleed points in the loft?

Have you tried bleeding the pump with the large silver screw in the middle of it as it is in the loft?
