If your GE washer smells like mildew, you’re likely dealing with a frustrating, persistent odor that just won’t go away. That damp, musty smell can transfer to your clothes, making freshly washed laundry smell anything but clean. This is a common issue with front-load and top-load GE washing machines, especially when routine maintenance is overlooked. Fortunately, you don’t need to replace your washer—just adopt a few simple cleaning strategies and consistent habits to solve the problem for good.
Let’s explore what causes this odor, how to clean your GE washer, and how to stop mildew from coming back in the future.
Why Your GE Washer Smells Like Mildew
A GE washer smells like mildew when moisture, detergent residue, and organic matter combine to create the perfect breeding ground for mold and bacteria. This is especially common in high-efficiency (HE) models, which use less water during wash cycles and leave more residue behind. Over time, detergent buildup and fabric softener scum cling to the drum, door gasket, detergent dispenser, and internal hoses.
Without proper airflow, these damp, soapy surfaces don’t fully dry, especially in humid laundry rooms. Mold spores can settle in, creating a foul smell that builds up each time the washer runs. The issue is particularly common in front-load washers, where the rubber door boot can trap moisture and grime.
In addition to poor airflow and detergent buildup, mildew smells can also stem from:
-
Lint trapped in the drain pump filter
-
Unwashed detergent drawers or softener compartments
-
Leaving wet clothes in the washer too long
-
Using too much detergent or the wrong kind
How to Clean a GE Washer That Smells Like Mildew
Cleaning a GE washer that smells musty isn’t difficult, but it does require a few intentional steps. Whether you have a front-load or top-load model, a thorough deep clean will remove mildew-causing residue and freshen up your appliance.
GE Top-Load Washer Cleaning Steps
Top-load GE washers are more ventilated than front-load models, but mildew can still accumulate inside the drum and along the lid seal. Here’s how to clean it:
-
Remove any laundry and make sure the washer is empty.
-
Set the cycle to the hottest water temperature setting.
-
Pour 2 cups of distilled white vinegar directly into the tub.
-
Optional: Add 5–10 drops of tea tree oil for its natural antifungal and deodorizing properties.
-
Run a full wash cycle with no detergent or laundry.
-
After the cycle ends, wipe the tub walls, lid, and agitator with a rag soaked in a 1:1 vinegar-water solution.
-
Use an old toothbrush to scrub around the agitator base and under the rim.
-
Repeat this process once a month to prevent future buildup.
Allow the tub to air dry with the lid open for several hours after cleaning.
GE Front-Load Washer Cleaning Steps
When a GE front-load washer smells like mildew, the rubber door gasket is often the main problem area. Residue, hair, and water get trapped in the folds of the gasket, creating an environment where mold thrives. To deep clean it:
-
Mix equal parts white vinegar and warm water in a spray bottle.
-
Generously spray the door gasket, pulling back folds to reach inside the crevices.
-
Let the vinegar solution sit for 10–15 minutes.
-
Use a microfiber cloth or soft sponge to scrub the gasket thoroughly.
-
For extra cleaning power, dip the cloth in vinegar mixed with a few drops of tea tree oil.
-
Rinse the gasket with a clean damp cloth and dry completely with a towel.
Next, clean the detergent drawer and drum:
-
Remove the detergent and softener compartments and soak them in a solution of hot water and vinegar for 15 minutes.
-
Scrub away buildup using a toothbrush or small cleaning brush.
-
Reinsert the cleaned dispenser into the washer.
To finish, run a drum cleaning cycle:
-
Set the washer to the hottest and longest cycle.
-
Add 1 cup of white vinegar, 1/2 cup of baking soda, or 1 Affresh washer tablet directly into the drum.
-
Start the cycle with no clothes or detergent.
-
If the smell persists, repeat the process or run a rinse cycle afterward.
Preventing Your GE Washer From Smelling Like Mildew Again
Once the mildew smell is gone, keeping your GE washer clean and odor-free comes down to forming a few key habits. Preventative care will help you avoid future buildup and keep your laundry smelling fresh.
Here are some tips to follow:
-
Use only HE (high-efficiency) detergent if your model requires it, and follow dosage instructions.
-
Leave the washer door open after every cycle to allow airflow and drying.
-
Wipe the door gasket and drum dry with a towel after the final cycle of the day.
-
Clean the detergent drawer every 2–3 weeks to avoid mold growth.
-
Run a tub clean cycle monthly using vinegar, baking soda, or a washer cleaning tablet.
-
Avoid liquid fabric softeners, which leave behind waxy residue—use dryer sheets instead.
If your washer is located in a humid or poorly ventilated laundry room, consider using a small dehumidifier or opening a window during wash days to reduce moisture buildup.
