If your LG top load washer smells bad, you are not alone. This issue is a common complaint that signals a buildup of residue, moisture, or organic matter within the machine. The lingering odor is often a mix of stagnant water, mold, and the oils left behind from laundry detergent and fabric softener.
Identifying the Source of the Smell
The first step to solving the problem is pinpointing the exact location of the odor. In most cases, the smell originates from the gasket, the detergent dispenser, or the standing water at the bottom of the tub. Unlike front-load machines, top-load washers have a different architecture that traps water and debris in specific areas. Understanding these trouble spots is essential for effective cleaning.
The Gasket and Rim Seal
While top-load washers do not have a door seal like their front-load counterparts, they do have a porcelain or plastic rim around the opening. This rim can accumulate dirt, fabric softener spills, and lint. If you notice a musty smell when you open the lid, this rim is the prime suspect. The dark, damp environment creates the perfect breeding ground for mildew.

Stagnant Water at the Bottom
Because the tub sits above the drain pump, there is always a small amount of water left at the bottom of the machine after a cycle. If this water remains trapped for extended periods—especially in humid environments—it begins to smell like rotten eggs. This specific odor is usually caused by hydrogen sulfide gas produced by bacteria feeding on the stagnant water and organic residues.
Effective Cleaning Solutions
To eliminate the bad smell, you need to break down and remove the organic residue. Harsh chemical cleaners or specialized washer tablets are often necessary to reach into the hidden corners of the tub. Regular maintenance is the most reliable way to prevent the smell from returning.
- Hot Water and Bleach Cycle: Run an empty load using the hottest water setting your fabric type allows, combined with a cup of liquid chlorine bleach. This sanitizes the interior and dissolves soap scum.
- Vinegar and Baking Soda: For a natural approach, pour one cup of white vinegar directly into the tub and run a hot wash cycle. After the first cycle completes, sprinkle a cup of baking soda into the tub and run another hot cycle to neutralize odors.
- Manual Scrubbing: Use a soft cloth or sponge dipped in vinegar to wipe down the interior of the tub and the top rim. Pay close attention to any hard water deposits or visible grime.
Preventing Future Odors
Once the current smell is gone, the focus should shift to prevention. Leaving the lid open between washes allows the interior to air out and dry completely. This simple act reduces the moisture that bacteria need to survive. Additionally, using the correct amount of detergent is crucial; excess suds create more residue for water to trap.

| Prevention Method | How It Works |
|---|---|
| Leave Lid Open | Promotes airflow and dries the tub to prevent mold growth. |
| Use HE Detergent | Low-suds formula reduces residue buildup on the interior walls. |
| Regular Maintenance Washes |
When to Seek Professional Help
If the smell persists after thorough cleaning, the issue might be mechanical rather than sanitary. A failing drain pump or a clogged plumbing vent can cause sewage gases to back up into the washing machine. If you detect a raw sewage smell or notice that the tub is not draining correctly, it is time to contact a certified appliance technician to inspect the internal components.
Addressing a smelly LG top load washer quickly protects the integrity of your clothing and maintains a healthy environment in your laundry area. By combining a deep clean with consistent maintenance habits, you can ensure your machine operates fresh and efficiently for years to come.
