One moment while I get some information for you!

Expert:  Appliance Guru replied 2 months ago.

How loud is the noise and is the wash arm bumping against anything possibly?

Customer: replied 2 months ago.
Is the arm supposed to be loose?
Expert:  Appliance Guru replied 2 months ago.

They are wobbly yes, but make sure the nut is tight..note it tightens counterclockwise. And then check the upper wash arm for rotation and any blockages, often a slow thumping noise is wash arm related. See if you find anything on either arm.
