Front-Load Washer Smells Musty — How to Fix It
Front-load washers are efficient but notorious for a mildew smell, because the door seal traps water and the rubber gasket grows mold. The fix is cleaning the right hidden spots and changing a couple of habits.
Clean the Door Gasket
Peel back the rubber door boot and look in the folds — this is where water, lint, hair, and mold collect. Wipe it thoroughly with a 50/50 vinegar-water spray or a diluted bleach solution, getting into all the folds. This is the main source of the smell.
Clean the Detergent Drawer
Pull out the detergent dispenser drawer (most release with a tab) and scrub off the slimy detergent and softener buildup, plus the cavity it slides into. Mold grows here too.
Run a Tub Clean Cycle
Use a washing-machine cleaner tablet (or run the machine's "Tub Clean / Clean Washer" cycle with the recommended cleaner). Run it monthly. This clears the buildup you cannot reach.
Change Your Habits
Leave the door and the detergent drawer cracked open between loads so the drum dries out. Use far less detergent — front-loaders need only a tablespoon of HE detergent, and over-dosing is the biggest cause of buildup and smell.

Deep-clean the door gasket folds and the detergent drawer, run a tub-clean cycle with washer cleaner, then leave the door open between loads and use less HE detergent.
Front-loaders seal tightly and the door gasket traps water, creating a perfect spot for mold. Leaving the door open to dry is the key prevention.
