Kenmore dishwasher making very loud buzzing noise (video link)

[CGood]

The model number is 665.13492K600.
I think something is definitely broken, as when I pushed on of the racks in, it wouldn't close and I heard a crack when I pushed it a bit too hard. I just need to figure out what part should be replaced, so any advice is greatly appreciated. Thank you!

Sorry but I cannot guess at what you broke.

Open it up, remove the lower rack and take a look!!!!
Pull the upper rack out and then push it in to see if it is something to do with how this tray fits/seals to the back.
