Have you ever opened your washing machine door expecting that fresh laundry scent, only to be hit with a musty, unpleasant smell instead? You’re not alone. Smelly washing machines are one of the most common household complaints, and the good news is, they’re easy to fix (and even easier to prevent).
In this guide, we’ll explain why your washing machine smells, how to clean it properly, and simple habits to keep it fresh for good.
🧺 Why Does My Washing Machine Smell?
Over time, your washing machine can build up soap residue, limescale, dirt, and bacteria — especially in hidden areas like the door seal and detergent drawer. When these combine with the warm, damp environment inside the drum, it creates the perfect breeding ground for mould and odours.
Here are the most common causes of a smelly washing machine:
Detergent residue – Using too much detergent (or liquid-only detergents) can leave sticky build-up inside your washer.
Low-temperature washes – Modern machines often run at 30°C or 40°C, which saves energy but doesn’t always kill bacteria.
Dirty door seals – The rubber gasket around the drum traps moisture, lint, and grime.
Clogged filter or drain – A blocked filter can trap old detergent and fabric fibres.~
Leaving the door closed – Trapping moisture after every wash encourages mould growth.
🧽 How to Get Rid of Washing Machine Smells (Step-by-Step)
Here’s a simple cleaning routine that will make your machine smell fresh again — no professional needed.
Step 1: Clean the Door Seal
Mix warm water with a splash of white vinegar or baking soda.
Wipe around the rubber seal using a cloth or old toothbrush.
Pull back the seal gently to remove any trapped dirt or mould.
Dry thoroughly with a clean towel.
🧠 Tip: Do this once a week to prevent smells returning.
Step 2: Clean the Detergent Drawer
Remove the drawer completely (most slide out with a gentle pull).
Soak it in warm, soapy water.
Use a small brush to clean any built-up detergent residue.
Wipe the inside of the drawer housing before replacing it.
Step 3: Run a Hot Cleaning Cycle
Set your machine to its hottest cycle (usually 90°C or a “drum clean” mode).
Add either:
2 cups of white vinegar (for odour removal), or
a specialised washing machine cleaner.
Run the cycle with no clothes inside.
This kills bacteria and breaks down odour-causing build-up inside the drum and pipes.
Step 4: Clean the Filter and Drain
Locate the filter (usually at the bottom front behind a small flap).
Place a towel and shallow tray underneath to catch water.
Unscrew the filter and remove any lint, coins, or debris.
Rinse the filter under warm water and replace securely.
Step 5: Leave the Door Open
After every wash, leave the door and detergent drawer slightly open.
This helps moisture evaporate and prevents mould growth — one of the simplest and most effective habits for a fresh-smelling washing machine.
🌿 Bonus Tip: Use the Right Detergent and Temperature
To prevent future smells:
Use high-efficiency detergent designed for modern machines.
Run a hot wash once a month to keep bacteria under control.
Avoid overloading your washing machine — it prevents proper rinsing.
If your area has hard water, consider using a descaler regularly to prevent limescale build-up.
