How to Remove Odours from a Washing Machine: A Complete Guide
A smelly washing machine is a common problem in Australian homes, particularly in front-load machines. The musty, mildew-like odour that develops in front-loaders is caused by moisture and detergent residue trapped in the drum, door seal and detergent drawer. This guide explains how to eliminate odours effectively and prevent them from returning.
Why Does My Washing Machine Smell?
The main causes of washing machine odour are:
- Mould and mildew growing on the rubber door seal (most common in front-loaders)
- Detergent residue and softener buildup in the drum, hoses and drawer
- Low-temperature washing that doesn't kill bacteria effectively
- Keeping the door closed after a wash, trapping moisture
- Excess detergent that leaves residue inside the drum
Step-by-Step: How to Clean a Smelly Washing Machine
Step 1: Clean the Door Seal (Front-Loaders)
Peel back the rubber door seal and inspect for mould. Use a cloth dampened with a 50/50 white vinegar and water solution to thoroughly wipe under and around the seal. For heavy mould, use a small brush (old toothbrush) and a paste of bicarbonate of soda and water. Wipe clean and dry thoroughly.
Step 2: Clean the Detergent Drawer
Remove the detergent drawer completely (most slide out with a release button) and soak it in hot water. Use a brush to remove all detergent and softener residue. Clean the cavity behind the drawer with a cloth and rinse thoroughly before replacing.
Step 3: Run a Hot Drum-Clean Cycle
Most modern washing machines have a dedicated drum-clean or tub-clean cycle. Run this cycle with one of the following:
- 2 cups of white vinegar (pour into the drum) — natural and effective
- Half a cup of bicarbonate of soda in the drum + white vinegar in the drawer
- A commercial washing machine cleaner tablet (Dynaclean, Dr Beckmann Washing Machine Cleaner, etc.)
Step 4: Run a Second Hot Rinse Cycle
Follow the drum-clean cycle with a standard hot wash cycle (60°C if available on your machine) on empty to rinse away all loosened residue and cleaning agents.
Step 5: Clean the Drain Pump Filter (Front-Loaders)
The drain pump filter (usually located behind a small panel at the bottom front of the machine) collects lint, hair and foreign objects. If blocked or dirty, it can cause odours. Place a towel and a shallow tray in front of it, then unscrew the filter cap slowly to allow water to drain. Remove any debris, rinse the filter under a tap and screw back in firmly.
Preventing Future Odours
- Leave the door open between washes to allow the drum to dry
- Wipe the door seal dry after the last wash of the day
- Use the correct amount of detergent (overuse is a leading cause of buildup)
- Use HE (High Efficiency) detergent in front-load machines
- Run a drum-clean cycle once per month
- Occasionally run a hot wash at 60°C to kill bacteria
