New Samsung Washer Smells
It is normal for all things to smell a little bit when they are brand new. (Think "new car smell"), but in your case, I think this goes past a factory fresh scent. You should consult your washing machine manual on how to run a "cleaner" cycle. Typically it is like 1/4 cup bleach or something on an empty cycle. This should get rid of any smells coming from it!
