Complete Guide on How to Clean a Washing Machine

Even though your washing machine regularly uses water and detergent, it still needs proper cleaning to stay fresh and perform efficiently. Over time, detergent residue, lint, mould, and bacteria can build up inside the drum, filter, gasket, and detergent drawer—causing unpleasant smells and affecting washing performance.

This guide explains how to clean a washing machine properly at home with simple steps to help keep your washer hygienic, efficient, and running smoothly for longer.

Why Is It Important to Clean Your Washing Machine?

Washing machines operate in a warm and damp environment, making them a common place for mould, mildew, and detergent buildup.

Without regular cleaning, you may notice:

• Unpleasant odours inside the drum
• Residue on freshly washed clothes
• Reduced washing performance
• Longer cycle times
• Water drainage issues

Cleaning your washing machine regularly helps:

• Remove bacteria and mould
• Improve washing results
• Maintain fresh-smelling laundry
• Extend the lifespan of your appliance

In homes with frequent washing routines, especially in warm climates, regular maintenance becomes even more important.

How Often Should You Clean a Washing Machine?

As a general rule, clean your washing machine thoroughly at least once a month.

You may need to clean it more often if:

• You use the machine frequently
• You regularly wash heavily soiled clothes
• You notice bad smells or visible residue
• You use low-temperature wash cycles often

Simple maintenance between deep cleans can also help keep your washer fresh.

What Do You Need Before Cleaning a Washing Machine?

Before you start, prepare the following items:

• Microfibre cloth
• Warm soapy water
• Small brush
• Spray bottle
• Washing machine cleaner
• Towels or a shallow tray

Tip: A dedicated washing machine cleaner is recommended because it is specially designed to remove buildup without damaging internal components.

Safety reminder: Always unplug your washing machine before cleaning the pump or filter area.

How to Clean a Washing Machine Properly: 6 Easy Steps

Step 1: Run an Empty Hot Water Cycle

Before starting, make sure there are no clothes inside the drum.

Add the washing machine cleaner according to the product instructions. Depending on the cleaner type, it may need to go directly into:

• The drum
• The detergent dispenser

Then run the machine on its hottest normal cycle.

This helps dissolve detergent residue, remove odours, and clean the inside of the drum.

Some Zanussi washing machines include dedicated drum cleaning programs that simplify this process even further.

Step 2: Clean the Washing Machine Pump

After the cycle finishes, unplug the machine.

Locate the small access panel near the bottom front of the washer. Place towels or a tray underneath, as some water may drain out when opening the pump area.

Slowly unscrew the cap to release water carefully.

This step helps remove trapped dirty water that may contribute to unpleasant smells and bacteria buildup.

Step 3: Clean the Pump Filter

Remove the filter completely and inspect it carefully.

You may find:

• Lint
• Hair
• Coins
• Buttons
• Small objects left in pockets

Rinse the filter under warm water and gently scrub it with a small brush.

A clogged filter can affect drainage, increase vibration, and reduce washing efficiency.

Step 4: Clean the Rubber Gasket and Door

The rubber gasket around the door is one of the most common areas for mould and moisture buildup.

Gently pull back the folds and spray warm soapy water into hidden areas. Then wipe thoroughly using a clean cloth.

Make sure to clean:

• The folds of the gasket
• Soap residue
• Moisture buildup
• The inside of the washing machine door

This step helps prevent mould growth and unpleasant odours.

Step 5: Clean the Detergent Dispenser

Over time, detergent and softener residue can accumulate inside the dispenser drawer.

Remove the drawer carefully and separate any removable parts.

Soak them in warm soapy water, then scrub away residue using a small brush.

Before reinstalling the drawer:

• Wipe the cavity clean
• Remove remaining powder buildup
• Ensure everything is dry

A clean dispenser helps detergent flow properly during washing cycles.

Step 6: Wipe the Washing Machine Exterior

Finish by wiping the outside of the machine using a damp microfibre cloth.

Focus on:

• Control panel
• Buttons and knobs
• Door edges
• Exterior surfaces

Removing dust and detergent splashes helps keep your washer looking clean and well maintained.
