Base station vibration

[paternis]

Hello,
one of my base stations is making a strong vibration sound. The noise is trigger in full use and is rather strong. However, it still works, but it seems to me to be ready to give up. What should I do ?

I fixed the two bases on the wall and they are well fixed. they have not moved since they were put in place.

I will play the guarantee as it is still valid.
