Researched APP for existing problem stories for my model. Contacted APP Tech support and learned from Stanley Rymer that Samsung had revised the drain pump design and released a new assembly kit of parts to fix problem and a new assembly location. I did not buy the kit, but bought
AP5669738 bracket, DC67-00601A hose and DC97-17417A hose and relocated the pump to the washer outer frame base, connected new hoses and electrical connections to the pump. I could not have done this repair without APP tech and APP user resources
