A washing machine cleans your clothes, but it also needs cleaning itself. Over time, detergent residue, moisture, and lint build up inside the drum, door seal, and filter, reducing washing machine performance and causing unpleasant odours. Regular appliance care keeps your machine running efficiently and your laundry smelling fresh.

Key takeaways from this guide:

• How to clean the drum using simple household products

• How to remove mould and grime from the door seal

• How to locate and clean the pump filter

• How often each part of your machine needs attention

Why Does Your Washing Machine Need Cleaning?

Washing machines accumulate residue with every load. Detergent, fabric softener, and hard water minerals leave deposits that reduce efficiency and harbour bacteria.

Modern front-loader and top-loader machines use less water than older models. This water efficiency is great for household bills, but lower water volumes mean detergent and softener residue are less likely to be fully rinsed away. Over time, that build-up affects wash quality and can leave clothes smelling musty even after a full cycle.

How Do You Clean a Washing Machine Drum?

To clean your washing machine drum, run an empty hot wash cycle with a cleaning agent added directly to the drum. This loosens detergent build-up and kills bacteria without damaging internal components.

Here is a simple method that works well:

1. Remove any items from the drum.

2. Add 500ml of white vinegar directly into the drum, not the dispenser.

3. Run the hottest cycle available on your machine.

4. Once complete, wipe the inside of the drum with a damp microfibre cloth.

5. Leave the door open for at least an hour to allow the drum to dry fully.

For tougher build-up, use a commercial washing machine cleaner tablet in place of vinegar. These are widely available and designed specifically for this purpose.

Drum residue removal is a standard maintenance practice in appliance care. Hard water areas, common across parts of South Africa including Gauteng and the Western Cape, accelerate mineral deposit build-up inside drums. The cleaning process works by breaking down soap scum and limescale at a surface level, allowing the hot water cycle to carry the loosened residue out through the drain. The result is a cleaner drum interior and fresher-smelling laundry. 

How Do You Clean the Front-Loader Door Seal?

The door seal, also called the gasket, traps moisture, lint, and detergent residue in its rubber folds. Wipe it down after every few washes using a cloth dampened with a mild cleaning solution.

Step-by-step seal cleaning:

• Mix equal parts white vinegar and warm water in a small bowl.

• Dip a cloth or old toothbrush into the solution.

• Pull back the rubber folds carefully and clean inside each one.

• Pay extra attention to the bottom of the seal where water collects.

• Dry the area thoroughly with a clean cloth afterwards.

Mould growth inside the door seal is one of the most common complaints among front-loader owners. The rubber folds create a warm, damp space where mould spreads quickly if left unchecked. Cleaning the seal monthly and leaving the door ajar between washes are two of the most effective steps for preventing build-up before it becomes a problem.

How Do You Clean the Washing Machine Filter?

The pump filter traps lint, hair, coins, and small debris before they reach the pump. It should be cleaned every one to three months, depending on how often you run loads.

Locating and cleaning the filter:

1. Check your user manual for the filter location. It is usually at the front bottom of the machine behind a small access panel.

2. Place a shallow bowl or towel under the filter cover to catch residual water.

3. Slowly unscrew the filter cap and allow the water to drain.

4. Remove the filter and rinse it under running water, clearing any debris by hand.

5. Check the filter housing for remaining debris before replacing.

6. Screw the filter back firmly to prevent leaks.

A blocked filter reduces water drainage and can trigger error codes on your machine's display. Clearing it regularly is one of the simplest ways to protect washing machine performance over the long term.

What Cleaning Products Work Best?

Different parts of the machine respond to different products. This table gives a quick reference for routine appliance care:

Avoid bleach on rubber seals, as it accelerates deterioration over time. For the detergent drawer, soak it in warm water for 15 minutes and use an old toothbrush to remove stubborn residue from corners and channels.

How Often Should You Clean Your Machine?

For most households running four to six loads per week, a monthly drum clean and quarterly filter check keep the machine in good working order. Higher-usage households benefit from more frequent attention.

Signs your machine needs immediate cleaning:

• Clothes smell musty after washing

• Visible mould or dark marks on the door seal

• Slow water drainage or error codes appearing

• Detergent residue left on clothing after a full cycle

Frequently Asked Questions

How do you clean a washing machine with vinegar?

Add 500ml of white vinegar directly to the drum and run a hot, empty cycle. The acidity of the vinegar breaks down mineral deposits and soap residue without harming internal parts.

Can I use baking soda to clean my washing machine?

Yes. Baking soda is a mild alkali that neutralises odours and helps lift stubborn residue from the drum walls. Add half a cup to the drum alongside your vinegar for a more thorough clean, then run the hot cycle as normal.

Why does my washing machine still smell after cleaning?

Persistent odours usually mean residue remains in the door seal folds or the filter. Clean both thoroughly and leave the door open between washes to let moisture escape.

How do I know if my washing machine filter is blocked?

A blocked filter often causes slow draining, water pooling in the drum, or the machine stopping mid-cycle. Some machines display a specific error code when the filter needs attention.

Is appliance care for a front-loader different from that of a top-loader?

The core steps are the same, but front-loaders require more attention to the door seal due to their horizontal drum design. Top-loaders are generally less prone to seal mould but still benefit from regular drum and filter maintenance.

Keep Your Machine Working Well

Regular appliance care does not require much time once you have a routine in place. Cleaning the drum monthly, wiping down the seal every few weeks, and clearing the filter every 1 to 3 months covers the key maintenance areas.
