how to clean a smelly washing machine

You can usually fix a smelly washing machine with a deep clean using hot cycles, vinegar, and baking soda, plus some habit changes so the odor doesn’t come back.

Quick Scoop

• Run an empty hot wash with vinegar and/or a machine cleaner to kill bacteria and dissolve buildup.

• Scrub the rubber door seal, detergent drawer, and filter where gunk and mold hide.

• Leave the door open, remove wet clothes promptly, and wipe moisture after cycles to prevent future smells.

Why Your Washer Smells

A “cleaning machine” smells bad when soap scum, fabric softener, body oils, and limescale build up in damp, dark spots and feed bacteria and mildew. This is especially common in low‑temperature, quick washes and when the door stays shut between cycles. Front‑loaders are more prone because the rubber gasket traps water and grime, but top‑loaders can smell too if the drum, agitator, or filter stay dirty.

Step‑by‑Step: Deep Clean (Front‑Loader)

1. Empty and prep
   • Remove all laundry and detergent pods.

 * If your machine has a “drum clean” or “clean washer” cycle, plan to use it.

2. Deodorize the drum with vinegar
   • Pour about 2 cups of white vinegar directly into the drum.

 * Run the hottest, longest cycle (or the dedicated clean cycle) with no clothes.

3. Boost clean with baking soda
   • Mix ¼ cup baking soda with ¼ cup water and pour it into the detergent drawer, or sprinkle ½ cup directly into the drum if you don’t have a dispenser.

 * Run another hot cycle to neutralize odors and loosen residue.

4. Scrub the rubber gasket
   • Gently pull back the door seal and check for slime, dark spots, coins, hair, or lint.

 * Spray or wipe with a mix of equal parts vinegar and water, then scrub with a cloth or soft brush and dry thoroughly.

5. Clean the detergent drawer
   • Remove the drawer, soak in warm soapy water, and scrub mold and residue with a small brush.

 * Wipe inside the cavity where the drawer slides in, then dry and reinstall.

6. Tackle the filter and drain (if accessible)
   • Unplug the machine, open the filter panel (usually at the front bottom), and place towels and a shallow tray underneath.

 * Slowly open the filter or drain hose to let out stale water, remove debris, then wash the filter in warm water and wipe the housing.

Step‑by‑Step: Deep Clean (Top‑Loader)

1. Empty the machine
   • Remove all clothes and any loose items from the drum or agitator.

2. Hot cycle with vinegar
   • Set the washer to the largest load size and hottest water.

 * Add about 4 cups of white vinegar to the drum, let it fill, then pause for 30–60 minutes to soak if possible.

 * Resume and let the cycle finish.

3. Second cycle with baking soda
   • Add about 1 cup baking soda directly into the drum and run another full hot cycle to deodorize and break down buildup.

4. Clean agitator and rim
   • Wipe the inside of the drum, under the rim, and around the agitator with vinegar or soapy water and a cloth or brush.

 * Don’t forget the lid underside and hinges, which can harbor mildew.

5. Clean dispensers and filter
   • Remove bleach/softener trays, wash in warm soapy water, scrub residue, rinse, and dry.

 * If your model has a lint/filter basket, remove and clean it as per the manual.

Quick Habit Changes to Keep Smells Away

• Run regular hot “maintenance” washes
  • Use a specialized machine cleaner or vinegar on an empty, hot cycle every 1–3 months (or about every 30 washes).

• Let the machine dry out
  • Leave the door and detergent drawer slightly open between washes so moisture can evaporate.

* After big loads, wipe the door glass and gasket with a dry microfiber cloth.

• Avoid over‑soaping
  • Use the correct amount of HE (high‑efficiency) detergent; too much creates sticky residue that traps odor.

• Empty promptly
  • Don’t leave wet laundry sitting in the drum for hours, as this quickly causes musty smells.

Front‑Load vs Top‑Load Odor Hotspots

[1][3] [3] [9][5] [5] [8][3] [7] [5] [5]

Area	Front‑loader issue	Top‑loader issue
Door seal / gasket	Traps water, lint, and soap scum; common mold spot.	Not present, but lid edges can grow mildew.
Detergent drawer	Powder/liquid buildup and mold if never removed and cleaned.	Softener/bleach cups can cake and smell.
Drum and hoses	Low‑temp washes leave biofilm and bacteria.	Residue forms under rim and around agitator.
Filter / drain	Clogged filter and stagnant water cause strong odors.	Some models have hidden filters that need periodic cleaning.

When You Might Need Help

• The smell is sewage‑like and persists even after deep cleaning, which can suggest a plumbing or drain trap issue rather than just the washer.

• The machine shows error codes, fails to drain, or leaks during cleaning—time to check the manual or call a technician.

“My washer smells like a swamp no matter how much I clean it.”
Often, the missing piece in forum stories like this is the drain filter or the habit of keeping the door shut 24/7—once those change, the odor usually goes away.

Quick TL;DR

• Run one or two empty hot cycles with vinegar and baking soda or a dedicated cleaner.
• Scrub the gasket, drawer, drum, and filter, and dry everything you can reach.
• Keep the door open, use less detergent, and do a hot “maintenance” clean every month or so to stop the smell coming back.
