If you find anything, carefully take it out before re-starting the dishwasher.

While humming as well as buzzing sounds may be completely routine they could also indicate a fault. A damaged motor could produce a loud humming or even shrieking sound, if this happens it will usually need to be replaced.
A damaged pump may also produce a rattling noise.
