Samsung Washer Smells Like Mildew? Here's How to Clean It

Why Does My Samsung Washer Smell Bad?
Here's the short answer: to clean a smelly Samsung washer, air the tub, wipe damp areas, run the cleaning cycle, clear old water, and reduce detergent buildup.
So, these checks show how to get rid of mold when the Samsung washer smells like mildew, and where to look if it smells like rotten eggs.
Use the Cleaning Directions in the Manual
In many cases, run the Samsung cleaning cycle with an empty tub and only the cleaner or bleach amount allowed in the manual. If there is no named cleaning cycle, follow the model's regular cleaning directions.
Remember, never mix bleach with vinegar, ammonia, or another cleaner. Extra product does not clean better and may leave more residue.
The cleaning cycle on your Samsung sometimes need only a simple correction while you look over the machine.
Keep the Detergent Drawer Clean
Also, use the detergent type and amount listed for the Samsung washer. Too much soap leaves a film that traps lint, moisture, and odor.
So, if the drawer is stuck, wet, or leaving soap behind, follow the full steps for a Samsung washer that is not dispensing detergent. That guide explains how to clean a smelly washer drawer without forcing it.
This detergent buildup problem sometimes come and go on a Samsung as you inspect it.
Clean Reachable Damp Areas
Before moving on, use a soft cloth and a cleaner approved for the Samsung washer. Wipe reachable seal folds on a front loader, or the tub rim, lid, and reachable wash plate area on a top loader.
In many cases, wear gloves and never scrape a seal with a sharp tool. A cracked or deeply molded seal should be replaced by a technician.
This part around the seal area often get forgotten on a Samsung washer during your first check.
Remove Wet Clothes Promptly
As you work, take wet laundry out of the Samsung washer soon after the cycle. Wipe visible moisture and leave the door or lid open when the machine is unused, as long as children and pets cannot get inside.
Before moving on, a closed damp tub lets a mildew smell return quickly. Giving it time to dry can clear a light odor and slows new growth.
A small damp tub problem on the Samsung often cause a much bigger symptom while you look for the cause.
Clean the Drain Filter Safely
At this point, standing water can make the Samsung washer smell like rotten eggs. If the manual shows a user accessible pump filter, unplug the machine, prepare for water, and clean it as directed.

So, straighten the drain hose and check for a reachable blockage. If the smell is strongest at the wall drain or other fixtures, ask a plumber to inspect the household drain.
