You pop open your washing machine, expecting fresh, clean laundry—but instead, you’re hit with a not-so-lovely odour. Even after running another cycle (maybe with an extra dose of fragrant detergent), the smell lingers. Sound familiar?
If your washing machine smells bad, it could be suffering from a serious case of built-up grime, bacteria, or trapped water. But don’t worry—this guide will help you identify the cause and, most importantly, fix it for good.
Why Does My Washing Machine Smell?
Washing machines are designed to clean clothes, but over time, residue, moisture, and bacteria can build up—leading to that unpleasant musty or even sewage-like smell. Here are the main culprits behind a smelly washing machine:
1. Detergent & Fabric Softener Buildup
Ironically, your detergent could be the reason your machine smells bad. Liquid detergents and fabric softeners often leave behind sticky residue, trapping dirt and bacteria inside the drum, dispenser, and seals. Over time, this can create a breeding ground for mould and mildew.
2. Trapped Water & Poor Ventilation
Front-loading washing machines, in particular, can trap water in the drum—especially if the door stays closed between washes. A damp, humid environment is the perfect setting for bacteria, mould, and bad smells to thrive.
3. A Dirty Filter
Your washing machine’s filter catches lint, hair, and debris from your laundry—but if left uncleaned, it can become a source of bad odours and even affect your machine’s performance.
4. Clogged Drain Hose or Pipes
If your washing machine smells like sewage, the issue may be with the drainage system. Over time, waste from your laundry can clog the drain hose, pipes, or filters, preventing water from flowing out properly.
How to Get Rid of Washing Machine Smells (Once and for All!)
Now that you know why your washing machine smells, here’s how to fix it—and keep it fresh forever.
1. Use a Natural Deep Clean: Vinegar & Bicarbonate of Soda
This is the ultimate eco-friendly washing machine cleaner that works wonders:
- Add two cups of white vinegar to the detergent drawer.
- Sprinkle half a cup of bicarbonate of soda directly into the drum.
- Run a hot cycle (60°C or above) with an empty machine.
Why it works: Vinegar kills bacteria and breaks down grime, while bicarbonate of soda neutralises odours and lifts residue.
2. Switch Up Your Detergent
Liquid detergent can leave a sticky residue, so try alternating with powder detergent every few washes—it helps break down buildup and keeps your machine cleaner.
3. Leave the Door Open After Every Wash
One of the easiest ways to prevent bad smells? Keep your washing machine door open between cycles. This allows moisture to escape and prevents mildew growth.
4. Clean the Filter Regularly
Your washing machine filter traps all the dirt, lint, and soap scum from your laundry—so it needs regular cleaning.
- Locate the filter (usually at the bottom front of the machine).
- Remove it and rinse under running water.
- Give it a gentle scrub to remove any stubborn residue.
Tip: Clean your filter every 4-6 weeks to keep your machine running smoothly.
5. Check & Clean the Drain Hose
If your washing machine smells like sewage, check the drain hose for blockages. Detach it carefully and flush it through with hot water to remove any trapped debris.
How to Prevent Washing Machine Odours in the Future
Once you’ve deep-cleaned your washing machine, here’s how to keep it fresh for the long run:
✅ Wipe down the drum & rubber seal after every few washes.
✅ Run a hot vinegar wash once a month for maintenance.
✅ Use less detergent (yes, really—too much can cause buildup!).
✅ Keep the door and detergent drawer open between washes.
✅ Clean your filter regularly to prevent dirt from building up.
