LG Washer Smells Bad: Tub Clean Cycle, Door Seal, and ThinQ Reminders

Quick Answer

LG front-load washers develop odor from the door boot seal fold like all front-loaders. LG's specific advantage: ThinQ-connected models send a reminder notification when the Tub Clean cycle is due. Run Tub Clean monthly with no clothes and no detergent (or add 2 cups vinegar). LG's door boot seal design has a slightly wider fold opening than Samsung, making cleaning easier.
