Run a cleaning cycle monthly to prevent mold and odor buildup

Samsung front load washers have a Self Clean cycle built into the machine that cleans the drum and removes detergent residue, mold, and bacteria. You start it by pressing the Self Clean button (or selecting it from the menu on digital models), then running the cycle with no clothes inside. The machine uses hot water and agitation to scrub the interior. Most models complete this in about an hour.

If your washer does not have a Self Clean button, use the hottest water setting with a cleaning agent designed for washing machines — not regular detergent. Run a full cycle on the longest setting with an empty drum. Do this once a month, or more often if you live in a humid climate or notice odor between washes.

Key Takeaways

  • Run the Self Clean cycle monthly with no clothes inside to prevent mold and odor in the drum.
  • Clean the rubber gasket around the door by wiping it dry after each load and checking for trapped debris weekly.
  • Wipe the detergent dispenser drawer monthly and rinse it under running water to clear dried detergent buildup.
  • Leave the door open between washes so moisture can evaporate and mold cannot grow.

Clean the rubber gasket where mold grows fastest

The rubber seal around the door is where moisture and lint collect, creating the ideal environment for mold. After each load, wipe the gasket dry with a clean cloth, paying special attention to the creases where the rubber folds. Check inside the folds weekly for trapped lint, hair, or debris — use your finger or a soft brush to pull out anything you find.

If you see black spots or smell mold in the gasket, soak a cloth in white vinegar and wipe the entire seal thoroughly. Let the vinegar sit for 10 to 15 minutes, then wipe again with a damp cloth and dry completely. For stubborn mold, use a soft toothbrush to scrub the creases gently.

Empty and rinse the detergent dispenser drawer

Detergent and fabric softener dry inside the dispenser drawer and create buildup that can clog the lines and reduce cleaning power. Pull the drawer out fully — most Samsung models release with a button or by pulling straight out — and empty any remaining liquid or powder.

Rinse the drawer under warm running water, using a soft brush or old toothbrush to scrub away dried detergent from the corners and compartments. Dry it completely before sliding it back in. Do this once a month, or every two weeks if you use liquid detergent regularly.

Wipe down the drum and interior surfaces

Even after a Self Clean cycle, you may notice lint or detergent residue on the drum walls. Open the door and look inside — if you see white or gray buildup on the stainless steel, dampen a cloth with white vinegar and wipe the visible surfaces. You do not need to scrub hard; a gentle pass removes most residue.

Pay attention to the area around the drum opening where the gasket meets the metal. Lint collects there and can transfer to clothes on the next load. Wipe this seam dry after each use, especially after washing towels or blankets that shed.

Leave the door open to let moisture escape

The biggest cause of mold and odor in front load washers is trapped moisture. After each load, prop the door open — even just a few inches — for at least two hours so the interior can dry completely. If you run multiple loads in a day, leave it open between cycles.

If your home is very humid or you cannot leave the door open, run the Self Clean cycle more frequently — every two weeks instead of monthly. Some Samsung models have a "Dry" or "Ventilation" setting that runs a short cycle to evaporate moisture; check your manual to see if yours does.

Clean the water inlet filters if water flow slows

Samsung washers have small screens in the inlet hoses where water enters the machine. Over time, mineral deposits and sediment can clog these filters and reduce water pressure. If you notice the washer fills more slowly than it used to, the inlets may need cleaning.

Turn off the water supply at the wall, then unscrew the inlet hoses from the back of the washer. You will see a small mesh screen inside each connection. Rinse the screens under running water and use a soft brush to remove any buildup. If the screen is badly clogged, soak it in white vinegar for 30 minutes, then rinse and reinstall. Screw the hoses back on firmly and turn the water back on.

Use the right detergent to reduce buildup

Front load washers need high-efficiency (HE) detergent, which produces fewer suds and rinses out more completely. Using regular detergent or too much HE detergent leaves residue in the drum and gasket, which feeds mold growth. Check your washer manual for the recommended amount — most front loaders use significantly less detergent than top loaders.

If you have been using regular detergent or overdosing HE detergent, run two or three empty Self Clean cycles in a row to clear the buildup. Then switch to the correct detergent and amount going forward. This single change prevents most odor and mold problems.

Frequently Asked Questions

What should I use to clean a Samsung washer if I do not have white vinegar?

White vinegar is inexpensive and works well, but you can also use a commercial washing machine cleaner made for front loaders. Follow the product instructions — most require running a full cycle with the cleaner and no clothes. Avoid bleach unless your manual specifically recommends it, as it can damage rubber seals over time.

How often should I run the Self Clean cycle?

Once a month is standard for most households. If you wash heavily soiled items, live in a humid climate, or notice odor between cycles, run it every two weeks. If you leave the door open between loads and use the correct detergent amount, monthly cleaning is usually enough.

Can I use regular detergent in my Samsung front loader?

No. Regular detergent produces too many suds and does not rinse out completely, leaving residue that causes mold and odor. Use only HE (high-efficiency) detergent and follow the amount recommended in your manual — usually one to two tablespoons per load.

Why does my washer smell bad even after running Self Clean?

The gasket is likely the source. Run Self Clean, then thoroughly wipe and dry the rubber seal, checking the creases for trapped lint or mold. If the smell persists, soak the gasket area with white vinegar for 15 minutes, scrub gently, and dry completely. Leave the door open between loads to prevent moisture from returning.

Is it safe to use bleach to clean the inside of my Samsung washer?

Check your manual first — some Samsung models allow diluted bleach, while others recommend against it because it can degrade rubber seals. White vinegar is a safer choice that works just as well for mold and odor. If you do use bleach, dilute it heavily and run a full rinse cycle afterward.
