As the others have said, apparently the new Silent Spinners can be stiff so worth seeing how freely it runs. Have you checked the bedding underneath? I know my Syrian Cleo pushes hers around a bit so it doesn't look look it's blocking it but the bedding is just wedged enough to stop it turning properly or made it tip backwards a fraction. Of it's attached the bars, has it over tightened itself? You may be able to loosen it a bit.
