Samsung Dishwasher Leaving Brown Residue on Silverware

I am looking to fix a relatively new Samsung Dishwasher. The dishwasher works fine for the most part, but it consistently leaves a brown sticky residue on our silverware. I have tried to clean the dishwasher, the dishwasher filter itself, run on high heat settings, use citric acid, vinegar, pretty much anything you can find on Google. My dishes come out great, it’s just the silverware that comes out with this brown gunk on it. (We do rinse dishes and silverware before putting them into the dishwasher)

Are there any additional steps that I can take to troubleshoot this?

Also, could be related, but the dishwasher also emits a wet dog smell when running.

Any guidance is much appreciated on this as I’m a new homeowner.
