Smell on towels (by 2 users)

I also have had issues with a bad smelling LG Tromm 2277 washer when we leave the door closed after using it. One note on the LG site mentions that soap/scum buildup on the washer drum can encourage mold growth. They suggested running an empty wash load and then pause it after the water fills and add a hot tub cleaning product (Whirl Out - I got it at Lowe's) and restart the load. This stuff should help remove the soap scum and limit the smelly mold growth. My washer does not smell as bad after using it. I also have run an empty cycle with only bleach using the very hot sanitary load setting.
