A washing machine that smells bad can turn a simple chore into an unpleasant experience. That musty, sour, or even rotten odour coming from your washer is a common problem. It usually means there’s a build-up of dirt, detergent residue, or mould inside the machine. Luckily, fixing this issue is often straightforward and doesn’t require expensive repairs.
In this post, I’ll share practical steps to get rid of that bad smell and keep your washing machine fresh. I’ll also mention some useful products and services that can help maintain your appliance in top shape. Whether you’re a homeowner or run a small business, these tips will save you time and hassle.

Why Does Your Washing Machine Smell Bad?
A washing machine can develop a bad smell for several reasons. Understanding these causes helps you fix the problem properly.
Mould and Mildew Growth
Washing machines, especially front loaders, can trap moisture in the rubber door seal and detergent drawer. This damp environment encourages mould and mildew to grow, causing a musty smell.
Detergent and Fabric Softener Residue
Using too much detergent or fabric softener can leave a sticky residue inside the drum and pipes. Over time, this residue traps dirt and bacteria, which produce unpleasant odours.
Clogged Drain or Filter
If the drain hose or filter is blocked, dirty water may stay inside the machine. This stagnant water can smell bad and affect washing performance.
Leaving the Door Closed After Use
Closing the door immediately after a wash traps moisture inside. Without airflow, the damp environment encourages bacteria and mould growth.
Knowing these causes helps you target the right fix and prevent the smell from coming back.
How to Get Rid of Washing Machine Smell
Here are simple steps you can follow to remove bad odours from your washing machine.
1. Clean the Door Seal and Drum
The rubber door seal is a common place for mould to hide. Wipe it down with a cloth soaked in a mixture of equal parts water and white vinegar. Pull back the seal gently to clean inside the folds.
Next, run an empty hot wash cycle with a cup of white vinegar or a washing machine cleaner. Vinegar helps kill bacteria and remove soap scum.
2. Clean the Detergent Drawer
Remove the detergent drawer and soak it in hot water mixed with vinegar or a mild detergent. Use an old toothbrush to scrub away any residue or mould. Rinse well and dry before putting it back.
3. Check and Clean the Filter
Most washing machines have a filter that traps lint and debris. Check your user manual to locate it. Remove the filter and clean it under running water. This step helps prevent blockages that cause bad smells.
4. Leave the Door Open After Washing
After each wash, leave the door and detergent drawer open to let the inside dry out. This simple habit stops moisture build-up and mould growth.
5. Use the Right Detergent Amount
Using too much detergent can cause build-up. Follow the detergent packaging instructions and adjust for water hardness and load size.
6. Run Regular Maintenance Washes
Run a maintenance wash once a month. Use a washing machine cleaner like RePair Team’s Appliance Cleaner or a cup of white vinegar on a hot cycle. This keeps the drum and pipes clean.
