My Samsung dryer DV50K7500GV/A3 with steam, did the exact same thing. Its exactly 17 monrhs old. Dryer stopped spinning, thought belt broke, plastic idler pulley melted and fell off pin, found on bottom of the dryer after my wife said she heard a loud bang. Samsung should offer new recall or new design, or replace free of charge. $1300 for a dryer I'm going to have to fix every year, NOT. Bought a ball bearing design idler pulley off eBay $23. Will go back to LG for sure, our LG HE easier and dryer lasted 10+ years without a hiccup .
