Clean your Samsung washing machine monthly to prevent mold, odor, and buildup

A Samsung washing machine needs cleaning roughly once a month, depending on how often you use it and whether you use cold water. Detergent residue, fabric softener, and moisture create an environment where mold and bacteria grow — especially in the rubber gasket around the door and inside the drum. The good news is that most Samsung models use one of two cleaning methods: a dedicated cleaning cycle, or a manual clean using vinegar and baking soda. Both take less than an hour and cost almost nothing.

The exact steps depend on whether your model has a Self Clean cycle (newer machines) or requires manual cleaning (older models). Either way, you will be working with the same problem areas: the rubber door gasket, the detergent dispenser, the drum itself, and the filter at the bottom front of the machine.

Key Takeaways

  • Samsung washing machines with a Self Clean cycle run it at high temperature for about 40 minutes and require no manual scrubbing.
  • Machines without Self Clean can be cleaned by running hot water with two cups of white vinegar, then baking soda, on the longest cycle available.
  • The rubber door gasket traps the most debris and mold; pull it back and wipe the groove with a damp cloth after every few loads.
  • The detergent dispenser drawer slides out on most Samsung models and should be rinsed under running water monthly.
  • The drain filter at the bottom front of the machine catches lint and coins; empty it every month to prevent clogs.

Using the Self Clean cycle on newer Samsung models

If your Samsung washing machine has a Self Clean button or cycle option on the control panel, use it. Press the button or select the cycle from the menu, then start the machine. The cycle runs hot water and agitation for roughly 40 minutes with no clothes inside. You do not add anything — no vinegar, no baking soda, no detergent. The heat and motion alone clean the drum and internal parts.

Run Self Clean once a month, or more often if you notice odor or visible mold. Some Samsung models will display a notification on the screen when cleaning is due; if yours does, follow that prompt. After the cycle finishes, leave the door open for at least an hour so the drum dries completely. Moisture left inside will breed mold again within days.

Manual cleaning with vinegar and baking soda for older models

If your Samsung washing machine does not have a Self Clean cycle, you can clean it manually using two common household items. Fill the detergent dispenser with two cups of white vinegar (not cleaning vinegar, which is too strong). Select the longest, hottest cycle available — usually labeled "Heavy Duty" or "Sanitize" — and start the machine with no clothes inside. Let it run to completion.

Once that cycle finishes, sprinkle half a cup of baking soda directly into the empty drum. Run the longest hot cycle again. The vinegar loosens buildup and kills bacteria; the baking soda removes odor and any remaining residue. After the second cycle finishes, wipe down the inside of the drum with a damp cloth to remove any baking soda dust, then leave the door open to dry.

Cleaning the rubber door gasket

The rubber gasket around the door is where mold and mildew grow most often, because water and detergent get trapped in the groove. You can see it as a thick rubber ring that the door presses against when closed. Pull the gasket gently away from the metal drum to expose the groove underneath, and wipe it with a damp cloth or an old toothbrush. Pay special attention to the bottom of the gasket, where water pools.

Do this every few loads, or at least once a week if you use the machine frequently. It takes two minutes and prevents the black spots and smell that signal mold growth. If mold has already appeared, soak a cloth in white vinegar, tuck it into the groove, and let it sit for 30 minutes before scrubbing. For stubborn mold, use a soft brush — do not use a scouring pad, which can tear the rubber.

Emptying and rinsing the detergent dispenser

The detergent dispenser drawer — the small compartment on the left side of the door on most Samsung models — collects detergent residue and fabric softener buildup. Slide it out by pressing the release button or lever (usually in the center of the drawer), then rinse it under hot running water. Use an old toothbrush to scrub the corners and the slot where the drawer slides in.

While the drawer is out, look inside the cavity where it sits. You may see dried detergent or mold. Wipe this area with a damp cloth. Rinse the drawer one more time and slide it back in. Do this once a month, or more often if you use fabric softener regularly — softener leaves more residue than detergent alone.

Checking and cleaning the drain filter

At the bottom front of your Samsung washing machine, usually behind a small panel or door, is a drain filter that catches lint, coins, and other debris. Open the panel by pressing or unlatching it — the method varies by model, so check your manual if you are unsure. You will see a cylindrical filter that you can twist counterclockwise to remove.

Hold the filter over a sink or bucket and rinse it under running water. Use an old toothbrush to scrub away lint buildup. If the filter is clogged, soak it in hot water for 10 minutes before scrubbing. Twist it back in clockwise until snug — do not force it. Check this filter every month, or more often if you wash heavily soiled clothes or have pets that shed. A clogged filter can cause the machine to drain slowly or not at all.

Preventing buildup between cleanings

The easiest way to keep your Samsung washing machine clean is to prevent buildup in the first place. Leave the door open after every load so the drum dries completely. Use the correct amount of detergent — too much leaves residue that feeds mold. If you use cold water most of the time, run a hot water cycle with vinegar once a month, because cold water does not kill bacteria as effectively.

Wipe the door gasket groove every few loads, and empty the drain filter monthly. These small habits take minutes and will keep your machine fresh and odor-free without needing a deep clean as often. If you notice a smell developing, do not wait for the next scheduled cleaning — run a Self Clean cycle or vinegar cycle right away.

Frequently Asked Questions

Can I use bleach instead of vinegar to clean my Samsung washing machine?

Bleach works but is harsher on rubber seals and metal parts than vinegar. If you choose bleach, use one cup in the detergent dispenser on the hottest cycle, then run an empty rinse cycle afterward to flush out any remaining bleach. Vinegar is gentler and equally effective for monthly cleaning.

What does the Self Clean cycle actually do?

The Self Clean cycle heats water to a high temperature and agitates the drum for 30 to 40 minutes with no clothes inside. The heat kills bacteria and mold; the motion dislodges detergent residue and debris from the drum walls and internal components. It is the fastest way to clean a Samsung machine if your model has it.

Why does my washing machine still smell bad after cleaning?

The smell usually comes from the door gasket, which traps moisture and mold in its groove. Wipe the gasket thoroughly after cleaning, and leave the door open for several hours to dry completely. If the smell returns within a week, the gasket itself may be damaged or the drain filter may be clogged — check both before running another cleaning cycle.

How often should I clean the drain filter?

Check and rinse the drain filter once a month as part of routine maintenance. If you wash heavily soiled clothes, have pets, or notice the machine draining slowly, check it every two weeks. A clogged filter is one of the most common reasons a washing machine stops draining properly.

Is it safe to run the Self Clean cycle with clothes inside?

No. The Self Clean cycle uses very hot water and strong agitation designed to clean the drum, not wash clothes. Running it with clothes inside can damage fabrics and may void your warranty. Always run it on an empty machine.
