grundfos alpha 2 L15-60 130 noise

Hi all

Have had the above pump in the house for 5+ years and it has worked really well. Just recently though it has started making a "knocking" noise when set to III (which it always has been). If I turn it down to II then it goes away - video attached

Any thoughts or suggestions on what to do? Is it on its way out?

Thanks in advance
