You open the washer door and get hit with it. That damp, sour, wet-towel smell. Worse, your "clean" laundry smells a little like it too.

A front-load washer that smells musty is one of the most common laundry problems there is. It isn't a sign that the machine is broken. It's a sign that moisture, soap, and lint have built up in places you can't see.

The good news is that you can usually fix it at home in about an hour. This guide shows you where the smell comes from, how to clean it out, and how to keep it from coming back.

Why Front-Load Washers Get Musty

Front-load washers use less water than old top-load machines. That saves money. But it also means less water to flush everything out.

Three things work together to cause the smell:

• Moisture. The door seals tight. Water stays trapped in the rubber and in the drum after every wash.
• Soap residue. Detergent and fabric softener leave a film that mold and bacteria feed on.
• Lint and body oils. Dirt from clothes sticks to that film.

Warm, damp, and dark is where mildew grows best. A closed washer door is exactly that.

Play Smell Detective: Where Is It Coming From?

Different smells point to different spots. A quick sniff test saves time.

Smells musty when you open the door. Check the rubber door seal (the gasket). This is the number one culprit.

Smells strong from the soap drawer. Old detergent and softener have turned moldy.

Smells like rotten eggs or sewage. Look at the drain pump filter and the drain hose. It can also come from your home's drain line.

Clothes smell sour, even when the drum looks clean. Too much detergent, or cold washes that never fully rinse out the soap.

Smells like something burning. Stop. Unplug the washer and call a technician. That's not mildew.

How to Get Rid of the Smell: 7 Steps

Set aside about an hour. You'll need a few cloths, an old toothbrush, a small bowl, and a washer cleaner (or the cleaner your manual recommends).

Step 1: Wipe the Door Gasket

Pull back the rubber seal and look inside the folds. You'll probably see slime, black spots, or trapped hair, socks, and lint.

Wipe it all out with a cloth and a warm, soapy solution. Use the toothbrush for stubborn spots. Dry it with a clean towel.

For heavy black mold, some manufacturers allow a diluted bleach solution on the gasket. Check your manual first. Never mix bleach with vinegar or ammonia. The fumes are dangerous.

Step 2: Clean the Detergent Drawer

Pull the drawer all the way out. Many slide off with a small release tab. Soak it in warm water and scrub off any gunk. Look into the empty slot too, since mold grows in there.

Let everything dry before you put it back.

Step 3: Clean the Drain Pump Filter

This step surprises people. Many front-load washers have a small filter near the bottom front, behind a little panel. It catches coins, lint, and hair. When it clogs, water sits and smells.

1. Unplug the washer.
2. Put a towel and a shallow pan on the floor.
3. Open the panel. Turn the filter slowly. Water will come out.
4. Pull the filter out and clear off the debris.
5. Rinse it, put it back, and close the panel.

If your manual shows a different location, follow it.

Step 4: Run a Cleaning Cycle

Many washers have a "Tub Clean" or "Clean Washer" setting. Use it with the cleaner your manufacturer recommends. Washer cleaning tablets from the store also work.

If your washer has no cleaning cycle, run the hottest, longest cycle with the drum empty and the cleaner added.

A note on vinegar: it's popular, but some manufacturers warn that regular use can wear down rubber seals. Check your manual before using it.

Step 5: Wipe the Drum and Door

When the cycle ends, wipe the inside of the drum and the glass door. Remove any leftover film.

Step 6: Dry It Out

Leave the door open. Leave the drawer slightly open too. Let it air out for several hours, or overnight.

Step 7: Run a Test Wash

Wash a small load with a bit of detergent. If the smell is gone, you're done. If it's still there, repeat the cleaning cycle or check the "still smells?" section below.

How to Stop the Smell From Coming Back

Cleaning fixes the smell today. These habits keep it away.

• Leave the door open after every wash. This is the biggest one.
• Wipe the gasket after your last load of the day.
• Use less detergent. More soap does not mean cleaner clothes. It means more residue.
• Use high-efficiency (HE) detergent. It's made for low-water machines.
• Go easy on fabric softener. It builds a sticky film. Use a small amount or skip it.
• Don't overload the drum. Clothes need room to rinse.
• Take wet clothes out right away. A damp load sitting for hours starts to sour.
• Run a hot wash now and then. Warm water helps break down residue. Cold-only washing lets it build up.
• Run a cleaning cycle once a month.
• Keep the soap drawer slightly open to let it dry.

Still Smells? Check These

If you cleaned everything and the smell stays, look for a deeper cause.

• Standing water in the drum. Water that doesn't drain fully will smell fast. Check the drain hose for kinks, and look again at the drain pump filter.
• A blocked or dirty drain hose. Residue can build up inside the hose.
• Mold behind the gasket. The gasket can hide mold that wiping can't reach. If the rubber is torn, stained deep in the folds, or smells even after cleaning, it may need replacing.
• A sewage smell. This can come from your home's drain pipe and not the washer. A dry or blocked drain trap can let sewer odors back up.
• Water leaking inside the machine. Leaks can create hidden damp spots.
• A worn seal or bearing issue. A very strong or odd smell, paired with noise or shaking, can point to a bigger problem.

When to Call a Technician

Try the steps above first. Call a pro if:

• The smell comes back within days of a deep clean
• Water won't drain, or you see standing water
• The gasket is torn, cracked, or deeply moldy
• You smell burning, or notice a hot or electrical odor
• You see leaks under the machine
• The washer is noisy, shaky, or the door won't open

Frequently Asked Questions

Q: Why does my front-load washer smell musty?
A: Moisture, soap residue, and lint build up in the door seal, drawer, drum, and drain filter. Mildew grows there because the door stays shut and the area stays damp.

Q: How do I get the mildew smell out of my washing machine?
A: Wipe the gasket, clean the soap drawer and drain filter, run a cleaning cycle with a washer cleaner, then leave the door open to dry.

Q: Can I use vinegar to clean my washer?
A: Many people do, but some manufacturers warn it can damage rubber seals over time. Check your manual first. Never mix vinegar with bleach.

Q: How often should I clean my front-load washer?
A: Run a cleaning cycle about once a month, and wipe the gasket after heavy use.

Q: Should I leave my washer door open?
A: Yes. Leaving the door and soap drawer slightly open lets moisture escape and prevents mildew.

Q: Why do my clothes still smell after washing?
A: Too much detergent, a dirty drum, or washing only in cold water can leave residue behind. Clean the washer, use less detergent, and try an occasional hot wash.

Q: Is a musty washer a sign it's broken?
A: Usually not. It's most often a cleaning issue. But if the smell comes with leaks, standing water, or noise, have it checked.
