If your washer smells bad, it can make the entire laundry room feel less clean. In some cases, the odor may even transfer to clothing after a wash cycle.
Odors can develop from trapped moisture, detergent residue, laundry left sitting too long, or drainage problems.
Understanding why your washer smells bad can help you narrow down the issue.
Common Reasons Your Washer Smells Bad
Washer odors can have several different causes. Some develop when moisture, detergent residue, and laundry debris accumulate inside the machine. Others may be related to a drainage problem that requires professional attention.
Pay attention to the type of odor, when you notice it, and whether the washer is draining and operating normally. These details can help point you toward the most likely cause.
Buildup Inside the Washer
Detergent, body oils, lint, and other residue can gradually accumulate inside a washing machine. When that buildup remains damp between cycles, it can contribute to musty or stale odors.
Common signs include:
- A musty or stale smell inside the washer
- Odors that become more noticeable after a cycle
- Clothes that come out smelling less fresh than expected
- An odor that improves after cleaning but eventually returns
Manufacturers recommend cleaning washing machines regularly according to the instructions for the specific model.
If your washer otherwise operates normally, start by following the manufacturer’s cleaning instructions. Avoid cleaners or cleaning methods that are not approved for your model.
If the smell returns quickly after a thorough cleaning, there may be buildup in a less accessible area or another underlying problem. A professional washing machine repair technician can inspect the appliance and determine whether additional cleaning or repair is needed.
Too Much Detergent or Fabric Softener
More detergent does not necessarily produce cleaner clothes. Using too much detergent or fabric softener can leave residue inside the washer, particularly in areas that stay damp between loads. Over time, that buildup can contribute to musty or stale odors.
Signs that laundry products may be contributing include:
- Visible detergent or fabric softener residue
- Excessive suds during a wash cycle
- Clothing that does not seem to rinse completely
- Musty odors that persist between loads
Use the detergent type and amount recommended by the washer manufacturer. High-efficiency washers should use HE detergent, and using more than the recommended amount can make residue problems worse.
If you are using the correct detergent and amount but the odor continues after proper cleaning, professional service can help determine whether buildup in an inaccessible area or another washer problem is contributing to the smell.
Moisture and Buildup Around the Door Gasket
Front-load washers have a rubber door gasket that creates a watertight seal during operation. Because the gasket is regularly exposed to water, detergent, and laundry debris, moisture and residue can collect in its folds and contribute to musty or mildew-like odors.
You may notice:
- Moisture around the door seal
- Musty odors that are strongest near the washer door
- Visible residue on the gasket
- Odors that return between wash cycles
Wipe accessible areas of the door and gasket according to the manufacturer’s cleaning instructions. There is no need to remove, loosen, or disassemble the gasket.
When appropriate for your model, leaving the washer door slightly open between loads can also help remaining moisture evaporate.
If the gasket is damaged, no longer seals properly, or has buildup that cannot be removed through normal cleaning, schedule professional washer service. A technician can determine whether deeper cleaning or gasket replacement is necessary.
Wet Clothes Are Being Left in the Washer Too Long
Sometimes a washer smells bad because wet laundry remains inside too long rather than because something is wrong with the appliance.
Leaving damp clothing in the washer for an extended period creates conditions where musty odors can develop. Those odors can affect both the laundry and the inside of the machine.
Possible signs include:
- Clothes developing a musty smell after sitting in the washer
- The washer smelling worse after a finished load remains inside
- Odors appearing even though the washer otherwise operates normally
- The smell improving when finished loads are removed promptly
Whirlpool and Maytag recommend removing damp laundry after the cycle is complete to help reduce mildew-related odors.
Remove finished loads as soon as practical and allow the washer to dry between uses. If odors continue even when laundry is removed promptly and the washer is cleaned regularly, professional service can help determine whether another issue is responsible.
The Washer Is Not Draining Completely
A washer should remove used wash water during the cycle. If it does not drain completely, standing or stagnant water can contribute to unpleasant odors.
Drainage problems may involve a clogged filter, drain hose, drain pump, or another part of the washer’s drainage system.
Signs of a possible drainage problem include:
- Water remaining in the tub after a completed cycle
- Clothes coming out unusually wet
- A sour, stagnant, or wastewater-like smell
- Odors that quickly return after cleaning
- A drain-related error code
If your model has a homeowner-accessible drain pump filter, follow the owner’s manual for instructions on checking and cleaning it. Avoid disassembling the pump or accessing internal drainage components yourself.
If the washer still does not drain correctly, schedule professional service. A technician can diagnose the drainage system and determine whether the pump or another component needs repair or replacement.
A Drain Hose or Household Drain Problem
Not every unpleasant washer odor originates inside the appliance. A sewage-like smell may sometimes be related to the washer’s drain hose installation or the household drain system.
Possible clues include:
- A sewage-like smell rather than a musty odor
- Odors that become stronger when the washer drains
- A smell that persists after normal washer cleaning
- Other signs that wastewater is not draining as expected

You can visually check the accessible portion of the drain hose for an obvious kink or restriction, but avoid moving the washer or disconnecting plumbing unless the manufacturer’s instructions specifically direct you to do so.
If the odor resembles sewage or becomes stronger during draining, professional washing machine service is recommended. A technician can evaluate the washer and its drain connection. If the appliance is operating correctly and the odor appears to originate from the home’s plumbing, a plumber may be needed.
Helpful Troubleshooting Tips When Your Washer Smells Bad
If your washer smells bad, a few safe cleaning and maintenance steps may help remove trapped residue and excess moisture. Always follow the cleaning instructions in your washer’s owner’s manual.
- Clean the door gasket: For a front-load washer, gently wipe accessible areas around and within the folds of the rubber gasket to remove lint, hair, detergent residue, and trapped moisture.
- Clean the detergent dispenser: Remove and rinse the dispenser if the manufacturer’s instructions indicate that it is removable.
- Clean the drain pump filter: If your washer has a user-accessible filter, clean it according to the owner’s manual. Keep a towel or shallow container nearby because some water may drain out.
- Run the recommended cleaning cycle: Use the washer’s cleaning cycle and a manufacturer-approved washer cleaner. Never combine cleaning products.
- Use the correct detergent: Use the detergent specified for your washer, such as HE detergent for a high-efficiency model, and do not exceed the recommended amount.
- Remove wet laundry promptly: Take clothes out after the cycle instead of allowing damp loads to sit inside the washer for extended periods.
- Allow moisture to escape: Wipe away accessible moisture after washing and, when appropriate for your model, leave the door or lid and detergent dispenser slightly open between loads.
- Inspect the visible drain hose: Without moving the washer, look for an obvious kink or restriction in the accessible portion of the hose.
- Check for standing water: Water remaining after a completed cycle may indicate a drainage problem.
If these basic steps do not eliminate the odor, or if the washer has standing water, drainage errors, unusual noises, or recurring odors, schedule professional washer service.
If you notice a burning, electrical, or melting-rubber smell, stop using the washer and contact a professional technician. These odors can indicate a mechanical or electrical problem that requires proper diagnosis.
When It’s Time to Call for Washer Service
If your washer smells bad after routine cleaning and proper laundry care, the source may be somewhere that cannot be safely accessed or diagnosed without the proper tools and technical knowledge.
Consider scheduling professional service when:
- The odor keeps returning after normal cleaning
- Water remains in the washer after a completed cycle
- Clothes are consistently wetter than normal
- The washer produces a persistent sewage-like odor
- An error code appears along with the odor
- Unusual noises or performance problems occur
- The washer develops a burning, rubber-like, or electrical smell
If you notice a burning or electrical odor, stop using the washer. Do not remove panels, inspect wiring, test electrical parts, or attempt to access motors, pumps, or other internal components.
If normal cleaning and laundry care do not resolve the odor, our trusted washing machine experts can diagnose the source of the problem and determine what repair may be needed. Professional washer service can address the underlying issue rather than simply masking the odor.
