i have model samsung+dwy80m2020us+dishwasher and the racks are so rusted i can no longer use the dishwasher. production date 09-2018.  they started rusting out approximately 11 months ago.  this is first time i own samsung appliances and have never had this problem with other manufacturers in past with racks rusting out in 2 years.  i  did not know samsung made such shoddy products.
