Bad Odors (Mildew smell)

Wiki Article

That musty, sour smell emanating from your Samsung washing machine is more than just unpleasant—it’s a sign of microbial growth. The culprit is almost always mildew or bacteria thriving in the damp, dark recesses of your machine. Fortunately, Samsung has designed specific maintenance cycles and features to combat this. Below is a step-by-step, professional-grade solution to banish the odor for good.

## Understanding Why It Happens

Before solving the problem, understand the cause. High-efficiency (HE) washers, including Samsung’s Ecobubble or AddWash models, use less water than old agitator machines. While great for the environment and fabric care, this design means moisture lingers in the door gasket, the detergent dispenser, and the drain hose. When combined with fabric softener residue, body oils, and cold water cycles (which don’t kill mold spores), you create a breeding ground for mildew. **The smell isn't a defect—it's a hygiene issue** that requires regular maintenance.

## Step 1: The Immediate Clean – Self Clean+ or Eco Drum Clean

Samsung washing machines come with a dedicated **Self Clean+** cycle (sometimes labeled Eco Drum Clean on older models). This cycle uses super-heated water and high spin speeds to sterilize the drum.

1.  **Empty the machine completely.** Remove all clothes, including any stuck in the door seal.

2.  **Add cleaning agents.** Pour 300ml (about 1 cup) of liquid chlorine bleach OR 500g (2 cups) of citric acid powder directly into the empty drum. **Do not use both together.** Do not put detergent in the dispenser.

3.  **Run the cycle.** Press the Self Clean+ button or navigate to that cycle in the menu. For top-loaders, hold the “Aqua Jet” or “Extra Rinse” button for 3 seconds to activate the drum cleaning cycle.

4.  **Let it complete fully.** The cycle takes about 60–90 minutes. It will heat water to 70°C (158°F), killing 99.9% of bacteria and dissolving residue.

*If your machine lacks a self-clean cycle, run a “Heavy Duty” cycle on the hottest water setting with bleach or a washing machine cleaner like Affresh.*

## Step 2: Deep Clean the Gasket (The Main Offender)

The rubber door gasket (the seal around the door) traps water every cycle. Run your finger under the lip—you will likely feel slime. Here’s how to fix it:

- **Mix a solution:** 1 part distilled white vinegar to 1 part water, plus a few drops of dish soap.

- **Pull back the gasket:** Use a soft cloth or an old toothbrush dipped in the solution. Scrub deep into the folds and the drain holes at the 6 o’clock (bottom) position.

- **Check the drain hole:** At the bottom of the gasket, there is a small hole to let water drain back into the drum. If clogged with lint or coins, water pools permanently. Use a paperclip or toothpick to unclog it.

- **Wipe and dry:** After scrubbing, wipe away all black/grey residue. Then, manually dry the entire gasket with a microfiber towel. Leave the door **wide open** for at least 2 hours after cleaning.

## Step 3: Decontaminate the Detergent Drawer

The soap drawer is a hidden reservoir for black mold, especially if you use liquid fabric softener (which contains oils and animal fats that feed mildew).

1.  **Pull out the drawer:** Press the release lever in the center or on the right side (Samsung design varies). Pull straight out.

2.  **Remove the inserts:** Most Samsung drawers have a blue or white siphon cap and a liquid detergent plate. Pop these off.

3.  **Scrub everything:** Use hot soapy water and an old toothbrush. Focus on the softener compartment (often marked with a flower or star). Scrub the recess inside the machine where the drawer sits—spray it with vinegar.

4.  **Rinse and dry:** Rinse thoroughly with hot water. Leave the drawer and the cavity to air dry completely before reinserting.

## Step 4: The Drain Filter Emergency Clean

A foul smell often originates from stagnant water in the drain pump filter. If you’ve never cleaned it, prepare for a pungent experience.

- **Locate the filter:** On the front bottom-right (or bottom-left) of the machine, there is a small rectangular service door.

- **Place towels:** Water will spill. Put a shallow tray or towels on the floor.

- **Drain emergency hose:** Pull out the small black hose, remove its plug, and drain the water into your tray. That water will smell like swamp.

- **Unscrew the filter:** Turn the large circular filter counter-clockwise. Pull it out. Clean off lint, coins, hairpins, and black slime. Rinse it under hot water.

- **Clean the housing:** Shine a flashlight inside the pump housing. Use a bottlebrush or wet/dry vacuum to remove debris. Wipe it dry.

- **Reassemble:** Screw the filter back in clockwise firmly (not over-tightened), replace the hose plug, and close the door.

## Step 5: Long-Term Prevention – Change Your Habits

Cleaning once is useless if you return to bad habits. To keep your Samsung washer smelling fresh permanently:

- **The door rule:** After every wash, leave the door **fully open** for at least 4–6 hours. Also pull the detergent drawer open a few inches. This single habit eliminates 80% of mildew problems.

- **Ditch liquid softener:** It is the #1 cause of biofilm slime. Use white vinegar in the softener compartment instead (½ cup per load). Vinegar kills spores and softens fabric naturally.

- **Use powder detergent occasionally:** Powder has less fat and residue than liquid. Run a powder cycle once every two weeks.

- **Monthly maintenance:** Run the Self Clean+ cycle once a month, even if you don’t smell anything.

- **Wash warm:** Cold water cycles are energy-efficient but do not kill mold. Wash towels, bedding, and underwear in warm or hot water weekly to sanitize the machine.

## When to Call Samsung Support

If you have completed all five steps (cleaned the gasket, drawer, filter, and run a Self Clean+ cycle) and the odor returns within 24 hours of a single load, you may have a **biofilm infestation inside the internal hoses** that you cannot reach. In this case, call Samsung customer service. A technician may need to disassemble the outer tub or replace the drain hose. Also, if you smell a burning or chemical odor (not mildew), unplug the machine immediately—this indicates an electrical or motor issue.

**Final Verdict:** A clean Samsung washing machine never smells. The solution is 50% elbow grease (scrubbing the gasket and filter) and 50% behavior (leaving the door open and ditching fabric softener). Perform the deep clean described above once, then adopt the monthly Self Clean+ routine. Your laundry will smell fresh, and your machine will last for years.
