How to Fix a Washing Machine That Smells Bad
A washing machine that smells musty, mouldy or like rotten eggs is one of the most common appliance complaints. The good news is it's almost always fixable — and in most cases, you don't need a technician. Here's how to get rid of the smell for good.
Why Does a Washing Machine Smell?
The smell is usually caused by one or more of these things:
- Mould and mildew growing inside the drum, door seal or detergent drawer
- Detergent buildup that provides food for bacteria
- Leaving wet clothes in the drum for too long after a cycle
- Low-temperature washing that doesn't kill bacteria effectively
- A blocked or dirty filter
- Standing water in the pump or hose
Step 1: Clean the Door Seal (Rubber Gasket)
On front-load washing machines, the rubber door seal is the most common place for mould to grow. Pull back the seal and inspect it. Use a cloth soaked in a solution of one part bleach to four parts water (or white vinegar) to wipe down the entire gasket, including the fold where you can't easily see. Rinse thoroughly.
Step 2: Clean the Detergent Drawer
Remove the detergent drawer completely (there's usually a release tab). Soak it in warm, soapy water and scrub away any buildup. Also clean inside the drawer cavity with a brush or old toothbrush. Dry before reinserting.
Step 3: Run a Hot Drum-Clean Cycle
Most washing machines have a dedicated drum-clean cycle. If yours does, run it monthly. If not, run an empty cycle on the hottest setting (60°C or higher) with either a commercial washing machine cleaner (like Calgon or Dettol Washing Machine Cleaner) or two cups of white vinegar added to the drum. This kills bacteria and dissolves detergent residue.
Step 4: Clean the Filter
Front-load machines have a pump filter, usually behind a small panel at the bottom front. Unscrew it slowly (place a towel underneath as water will spill out) and rinse it clean. A clogged filter traps lint and debris which causes odour. Clean it every 3–6 months.
Step 5: Leave the Door Open After Washing
One of the most effective preventive measures is simply leaving the door and detergent drawer ajar after every wash. This lets moisture escape and prevents the damp, dark conditions that mould thrives in.
Step 6: Wash at Higher Temperatures Regularly
If you mostly wash at 30°C or cold, bacteria can build up over time. Run a hot wash (60°C) at least once a week to keep the drum clean.
When to Call a Technician
If the smell persists despite cleaning, there may be a drain hose blockage, a sump issue or a more serious mould problem inside the machine. At that point, it's worth having a technician inspect it.
