Why does my washing machine smell like mildew?
Improper cleaning, using the wrong type or amount of detergent, leaving clothes in the washer after a cycle and even a dirty dispenser drawer can be reasons why your washer smells like mildew. Take a look at the list below to discover common reasons why washing machines may develop a moist, mildew smell and what you can do to help stop it.
1. Dirty washer tub
If you can’t remember the last time you cleaned the inside of your washing machine, that may be a reason why your washer smells like mildew. Cleaning your washer every 30 cycles, or as needed, can help keep it ready for loads of clothes come laundry day. Refer to your owner’s manual for specific cleaning instructions to help prevent residues and odors from forming inside your washer.
Using affresh® washing machine cleaner tablets1 can clean deep inside your washer to help reduce residues and grime in hard-to-reach areas, such as the washing machine tub, valves, drain and more. Use these tablets monthly to help keep your appliance smelling as it should.
2. Using the wrong type of detergent
Using non-HE detergent for a high-efficiency washer can result in residue build-up, which can cause odors to develop inside your washing machine. Refer to your owner’s manual to help determine what kind of washing machine you have and to find out which type of detergent is best for your appliance.
3. Wet clothes left inside the washer
Leaving a load of wet clothes inside your washing machine for too long can lead to mildew growth, which may be the reason behind that musty smell coming from your appliance. Always remove your wet load of clothes as soon as possible after a cycle is complete to help prevent this from happening.
Select Whirlpool® Washers, like this front load model, come with a 12-Hour FanFresh® Option that tumbles clothes for up to 12 hours after a wash cycle, so you can finish the rest of your laundry routine whenever it’s most convenient for you.
4. Dirty dispenser drawer
Giving your washing machine a deep clean includes many overlooked areas, like your washer’s detergent dispenser drawer. Your dispenser drawer should be removed and cleaned regularly with water, mild soap and a soft sponge or cloth to help prevent any unwanted smells or odors.
5. Using too much detergent
Using more than the recommended amount of detergent can cause residue to build up inside your washer, which can lead to mildew odors. Always refer to your owner’s manual to find the ideal amount of detergent to use based on your load size and soil level.
Swash® Laundry Detergent2 features an Auto-Stop Top that stops dispensing detergent automatically when you have the right amount, so there’s no second guessing how much you need.
Why do my clothes smell like mildew after drying?
If you’re washing clothes inside a machine that’s begun to develop a mildew smell, this lingering odor may stay on your clothing even after it has been dried. Try cleaning your washing machine or consulting your owner’s manual on proper detergent usage to help combat the mildew smell in your washer.
If you left a load of wet clothes in the washer for too long and then tried to dry them, you may need to rewash the load if a mildew smell has developed.

You may just need to run a Clean Washer cycle or use affresh® washing machine cleaner tablets if it’s been quite some time since you’ve cleaned the inside of your appliance.
