Why Does My Washing Machine Smell?

A washing machine is supposed to clean your clothes, so it’s frustrating when the machine itself starts to smell unpleasant. If your washing machine has developed a musty or sour smell, it’s often due to a build-up of dirt, detergent, and moisture over time. Here’s why your washing machine might be smelling and what you can do to keep it fresh and odour-free.

Common Causes of Washing Machine Odours

1. Detergent and Fabric Softener Build-Up
   Over time, leftover detergent and fabric softener can accumulate in the drum, hoses, and detergent drawer, creating a sticky residue that can trap dirt and bacteria. This build-up becomes a breeding ground for unpleasant odours, particularly if the machine is used frequently with cool washes.

2. Moisture and Mildew Growth
   Washing machines are often damp environments, and if water is left to sit, it can lead to mildew and mould growth, especially around the door seal in front-loading machines. This is a common cause of that characteristic “musty” smell.

3. Lack of Regular Cleaning
   Washing machines need regular cleaning to stay fresh, but this is often overlooked. Without maintenance, the combination of detergent, fabric softener, and dirt leads to grime build-up that eventually causes foul odours.

4. Blocked Filter
   A clogged filter can prevent water from draining properly, causing dirty water to sit in the machine and create a bad smell. Clearing the filter regularly can prevent this issue.

How to Get Rid of Smell in Washing Machine

If your washing machine has started to smell, don’t worry – there are simple steps you can take to restore freshness. Here’s a step-by-step guide to banishing bad odours and keeping your machine smelling clean.

1. Clean the Detergent Drawer

Pull out the detergent drawer and rinse it under warm water to remove any build-up of detergent and fabric softener. Use an old toothbrush to scrub any hard-to-reach areas, and then dry it thoroughly before replacing it.

2. Wipe Down the Door Seal

The door seal on a front-loading machine is particularly prone to mould and mildew. Use a cloth and a solution of water and white vinegar to wipe down the rubber seal, paying special attention to any hidden folds where grime can build up. Be sure to dry it thoroughly to prevent further moisture build-up.

3. Run a Hot Cycle with Vinegar

To disinfect your machine and remove any lingering odours, add two cups of white vinegar to the detergent drawer or directly into the drum. Run a hot wash cycle (60°C or above) with no clothes inside. The vinegar will help dissolve soap scum, remove bacteria, and neutralise odours.

4. Follow Up with Baking Soda

After the vinegar cycle, add half a cup of baking soda directly into the drum and run another hot wash cycle. Baking soda acts as a deodoriser and will help eliminate any remaining odours, leaving your machine smelling fresh.

5. Clean the Filter

Check your machine’s filter for lint, coins, or other debris that might be trapped inside. A clogged filter can prevent proper drainage and lead to a build-up of dirty water, causing smells. Clear the filter, rinse it, and replace it carefully.

6. Leave the Door Open

After each wash, leave the door open for a few hours to allow the drum to dry out. This prevents moisture build-up, which reduces the chance of mould and mildew growth. Air circulation is essential for keeping your washing machine fresh.

Preventing Future Odours

To keep your washing machine smelling fresh in the long term, try these tips:

• Use the Right Amount of Detergent: Excess detergent can create residue, so always follow the manufacturer’s guidelines for the correct dosage.

• Run Regular Maintenance Washes: Every few weeks, run an empty hot wash cycle with vinegar or a washing machine cleaner to dissolve any residue and keep your machine clean.

• Avoid Overloading: Overloading the machine can prevent proper drainage, which may contribute to odours.

• Dry the Seal and Drum After Each Wash: Wipe down the door seal and leave the door open after each wash to prevent moisture from lingering.

By following these steps, you can prevent odours from building up and ensure your washing machine stays in top condition. A clean machine means cleaner, fresher clothes every time!
