Why Your Washing Machine Needs a Clean
The inside of your washing machine, particularly the drum, door seal, and detergent drawer, can become a breeding ground for bacteria, mould, and mildew. This is due to a combination of factors: residual detergent, fabric softener, lint, and the damp environment created after each cycle. Over time, this build-up leads not only to unpleasant odours but can also transfer onto your clothes, leaving them smelling less than fresh. Addressing this is crucial for maintaining hygienic laundry and extending the lifespan of your appliance. Regular cleaning isn't just about aesthetics; it's about performance and health.
Several issues can arise from a dirty washing machine. The most common complaint is a persistent musty smell that clings to freshly washed laundry, no matter how much detergent you use or how high the wash temperature. You might also notice visible mould or grime around the door seal or inside the drum. In more severe cases, blockages can occur in the filter or drainage system, leading to water pooling or longer cycle times. For those with sensitive skin, residue from mould and bacteria can potentially cause irritation.
Considering the variety of washing machines available, from standard freestanding units to integrated washing machines, the core cleaning principles remain consistent. Whether you own a Hisense washing machine, a Logik washing machine, or a Whirlpool washing machine, the internal mechanisms are susceptible to the same issues. Even portable washing machine units require attention. Neglecting the interior can mean your washing machine dryer washer struggles to perform efficiently, potentially impacting the performance of both the wash and dry cycles.
This guide will walk you through the process of tackling these internal issues, providing a clear plan for a thorough clean. We'll cover the materials you'll need, the step-by-step method, and some preventative measures to keep your appliance in top condition.
- Mould, bacteria, and soap scum build up inside washing machines.
- A dirty machine causes bad odours and can transfer smells to clothes.
- Regular cleaning maintains hygiene, performance, and appliance longevity.
- All types of washing machines benefit from internal cleaning.
Identifying the Signs of a Dirty Drum
Recognising the symptoms is the first step towards a cleaner machine. The most obvious indicator is an unpleasant smell emanating from the drum or the door seal, particularly noticeable when you open the appliance. If your clothes come out of the wash still smelling damp or musty, it's a strong signal that the washing machine itself needs attention. You might also observe visible residue, dark spots (which could be mould), or slime-like build-up around the rubber door seal, the detergent dispenser, or even inside the drum.
A less obvious, but equally important, sign is a reduction in cleaning performance. If clothes aren't coming out as clean as they used to, or if you notice an increase in lint or residue on them, the internal components might be clogged or coated. Detergent residue that fails to rinse away properly can also point to internal build-up affecting water flow and drainage. If your machine is making unusual noises, it could be due to debris accumulating in the drum or pump, a further indication that an internal clean is overdue.
A common mistake people make is only focusing on the exterior. The focus keyword "how to clean inside washing machine" highlights the critical, often overlooked, interior. While external wiping is good practice, it doesn't address the root cause of smells and performance issues. The most critical phrase to remember is that a clean machine ensures clean laundry.
Materials Needed for a Thorough Clean
Before you begin cleaning the inside of your washing machine, gather the necessary items. Having everything ready ensures a smooth and efficient process. The primary cleaning agents you'll need are a good quality washing machine cleaner or a natural alternative like white vinegar and bicarbonate of soda. You’ll also require a clean cloth or sponge, an old toothbrush for scrubbing tight spots, and possibly some rubber gloves to protect your hands from the cleaning solutions.
Your Cleaning Arsenal
- Washing Machine Cleaner: Commercially available washing machine cleaners are formulated to break down detergent residue, limescale, and microbial build-up. Follow the product's instructions carefully, as application methods can vary.
- White Vinegar: A natural disinfectant and descaler, white vinegar is excellent for tackling mould and mineral deposits. You will need approximately 500ml to 1 litre.
- Bicarbonate of Soda: Often used in conjunction with vinegar, or as a standalone paste, bicarbonate of soda is a mild abrasive and a powerful deodoriser. You'll need about 100-200g.
- Clean Cloths/Sponges: For wiping down surfaces and drying. Microfibre cloths are ideal for absorbing moisture and polishing.
- Old Toothbrush: Perfect for reaching into crevices, around the door seal, and inside the detergent dispenser compartments.
- Rubber Gloves: To protect your skin from cleaning agents and grime.
- Bucket: For mixing cleaning solutions or holding rinsing water.
Protect your washing machine's internal components by avoiding abrasive scourers or harsh chemicals not designed for appliance cleaning.
Understanding Dosage and Application
When using a commercial washing machine cleaner, adhere strictly to the dosage and application instructions on the packaging. These products are typically added directly to the drum or the detergent drawer, followed by running a hot cycle. If opting for white vinegar and bicarbonate of soda, you'll use them separately or in sequence. For instance, you might run a hot cycle with vinegar, then a second cycle with bicarbonate of soda, or create a paste for manual scrubbing.
Using too much cleaning agent can sometimes lead to excessive foaming or residue, which ironically requires further cleaning. Conversely, using too little might render the cleaning ineffective. Always consult the product label or recommended methods for natural alternatives to ensure correct usage.
The Cleaning Method: Step-by-Step
Cleaning the inside of your washing machine effectively involves a multi-stage process. This method targets the drum, seals, and dispenser, ensuring a comprehensive clean. For this process, we'll use a combination of white vinegar and bicarbonate of soda, as they are readily available, effective, and environmentally friendly alternatives to harsh chemicals. Always ensure your washing machine is empty before starting any cleaning cycle.
Step 1: Clean the Detergent Drawer
Begin by removing the detergent drawer. Most modern washing machines have a release mechanism that allows you to pull it out completely. Once removed, soak it in warm, soapy water or a solution of warm water and white vinegar for about 15-30 minutes. Use an old toothbrush to scrub away any built-up residue, mould, or detergent clumps. Pay close attention to the small compartments and spray nozzles within the drawer. Rinse thoroughly and dry before replacing it. If the drawer is severely stained or damaged, check your appliance manual for replacement options.
Step 2: Scrub the Door Seal
The rubber door seal is a prime location for mould and grime. Pull back the folds of the seal and inspect for any build-up. Spray a solution of white vinegar or a mild bathroom cleaner directly onto a cloth, or onto the seal itself if it's very dirty. Use the cloth and the toothbrush to carefully scrub away all mould, lint, and residue. Ensure you reach into all the crevices. After scrubbing, wipe the seal down with a clean, damp cloth to remove any cleaning agent, and then dry it thoroughly. This step is crucial for preventing unpleasant odours from developing.
Step 3: Run a Hot Drum Clean Cycle (Vinegar)
With the detergent drawer removed (or empty) and the door seal wiped clean, it's time for a hot wash. Pour 500ml of white vinegar directly into the empty washing machine drum. Close the door and run the machine on its hottest setting, ideally a 'Drum Clean' or 'Boil' cycle (usually 90°C or higher). If your machine doesn't have a specific drum cleaning cycle, select the hottest long wash programme available. The hot water combined with vinegar will help to dissolve grease, kill bacteria, and break down mineral deposits.
Step 4: Run a Second Hot Drum Clean Cycle (Bicarbonate of Soda)
Once the vinegar cycle has finished, sprinkle approximately 100-200g of bicarbonate of soda directly into the drum. Close the door and run another hot wash cycle, again on the highest temperature setting. The bicarbonate of soda acts as a deodoriser and mild abrasive, helping to scrub away any remaining residue that the vinegar loosened, and neutralising any lingering smells. This two-part process is highly effective for deep cleaning the interior.
Step 5: Wipe Down and Dry
After the final hot cycle, open the washing machine door and wipe down the inside of the drum and the door seal with a clean, damp cloth. This will remove any loosened debris that may still be present. Ensure the drum and seal are completely dry before closing the door. Leaving the door ajar after use also helps to prevent moisture build-up, a key factor in keeping the inside clean and fresh.
The effectiveness of this method hinges on using the hottest possible wash cycle.
Step 6: Clean the Filter
Locate and clean the washing machine's filter, usually found at the bottom front of the appliance behind a small panel. Place a towel and a shallow tray underneath to catch any residual water. Carefully unscrew the filter, remove any debris (lint, coins, buttons), and rinse it under running water. Clean the filter housing with a damp cloth before reinserting the filter and securing the panel.
For a truly fresh machine, tackling the interior is non-negotiable.
Preventative Maintenance: Keeping it Clean Longer
Once you've achieved a sparkling clean interior, the key is to maintain it. Implementing a few simple habits can prevent the build-up of mould, bacteria, and residue, meaning you won't need to perform such an intensive clean as frequently. Consistent preventative maintenance is the most effective way to keep your washing machine smelling fresh and performing optimally. This proactive approach saves you time and effort in the long run and protects your appliance.
Regular Door Seal Wiping
After every wash, or at least daily, take a moment to wipe down the rubber door seal with a dry cloth. This simple action removes moisture and any stray lint or hair that can trap dampness and encourage mould growth. For front-loading machines, ensure you also wipe the inside of the door glass. This quick habit drastically reduces the environment where mould thrives.
Leave the Door Ajar
Crucially, always leave the washing machine door slightly ajar between washes. This allows air to circulate inside the drum, helping to dry out any residual moisture. A closed, damp environment is an ideal breeding ground for bacteria and mould. For top-loading machines, leave the lid open as well.
Use the Right Amount of Detergent
Overdosing detergent, especially with high-efficiency (HE) machines, is a common cause of residue build-up. Modern machines use less water, so less detergent is needed. Always follow the manufacturer's recommendations on the detergent packaging and your washing machine manual. Excess detergent doesn't make clothes cleaner; it just creates more build-up inside the machine.
Run Hot Washes Periodically
Incorporate at least one hot wash (60°C or higher) into your laundry routine each week or fortnight. This helps to kill bacteria and dissolve detergent residue that lower temperature washes (like 30°C or 40°C) might leave behind. Hot washes are particularly beneficial for bedding, towels, and other household items that can harbour germs.
Consider using a washing machine cleaner monthly for ongoing maintenance, especially if you frequently wash at lower temperatures.
Clean the Detergent Drawer Regularly
Don't forget the detergent drawer. A quick rinse or wipe down every few weeks can prevent blockages and mould growth. If you use liquid detergents or fabric softeners, ensure the compartments are clear of dried residue. Some drawers are dishwasher safe, making cleaning even easier.
Maintaining a clean washing machine means ensuring good airflow.
Troubleshooting Common Washing Machine Odours
Even with regular cleaning, some washing machines can develop persistent odours. Understanding the potential causes can help you target the problem effectively. The keyword "clean inside washing machine" often relates to solving these odour issues, as they are the most common symptom of an internal problem.
Musty Smells from Mould
This is the most frequent complaint. Mould thrives in damp, dark conditions, especially around the door seal and drum. If you've cleaned the seal and run hot cycles but the smell persists, re-inspect the seal thoroughly, looking for hidden pockets of mould. Ensure the door is always left ajar and the seal is dried after each use. If mould is deep-set, professional cleaning or replacement of the seal might be necessary.
Chemical or Acrid Smells
Sometimes, a chemical or acrid smell can indicate an issue with the drainage system or a blockage. Check the filter for debris that might be causing a foul odour to recirculate. If the smell occurs during the drain or spin cycle, it could point to a problem with the pump or drain hose. Ensure no foreign objects are obstructing the pump.
Detergent Residue Smells
If you're using too much detergent or fabric softener, it can build up inside the machine and create a sticky residue that harbours bacteria and smells. This is particularly common if you primarily use low-temperature washes. Ensure you are using the correct amount of HE detergent and consider running an empty hot cycle with vinegar or a specialised cleaner to break down this build-up. Reduce the amount of detergent used in subsequent washes.
Always use high-efficiency (HE) detergent in HE machines to prevent excessive suds and residue.
What If the Smell Persists?
If you have performed all the recommended cleaning steps and preventative measures, and the odour remains, it may be time to consult your washing machine's manual or contact a qualified appliance repair technician. There could be a more complex issue, such as a problem with the pump, heating element, or internal ducting that is not accessible through routine cleaning. For specific brands like Hisense washing machine or Logik washing machine, check their official support pages for model-specific advice.
Addressing persistent odours requires a systematic approach.
Beyond the Drum: Cleaning Other Internal Components
While the drum and door seal are the primary areas requiring attention when you clean inside a washing machine, other internal components also benefit from periodic cleaning to ensure optimal performance and hygiene. Neglecting these parts can lead to reduced efficiency, blockages, or even component failure over time. This section covers areas often overlooked but crucial for the overall health of your appliance.
The Detergent Dispenser and Drawer System
As detailed in the cleaning method, the detergent drawer and its housing need regular attention. Residue from detergents, fabric softeners, and bleach can dry and harden, creating blockages or fostering mould. If your drawer is removable, soak it and scrub it clean. If not, use a toothbrush and a cleaning solution to meticulously clean each compartment. Also, clean the area *where* the drawer sits. Mould and grime can accumulate in the housing, affecting the flow of water and cleaning agents into the drum.
The Pump and Filter Assembly
The washing machine pump filter is designed to catch lint, coins, hairpins, and other small debris that could otherwise damage the pump or block the drainage system. This filter should be checked and cleaned regularly, typically every 3-6 months, or whenever you notice drainage issues or unusual noises. A clogged filter can lead to water remaining in the drum after a cycle, prolonging dampness and contributing to smells. Always place towels and a shallow container beneath the filter access panel to catch water.
Internal Hoses and Ducts
While not easily accessible for manual scrubbing, internal hoses and ducts can accumulate lint, detergent residue, and biofilm. The primary way to address these is through regular hot washes with appropriate cleaning agents, as described earlier. The high temperatures and cleaning solutions help to break down and flush out build-up within these pathways. If you suspect a significant blockage in these areas, it may require a service technician to inspect and clean them.
Ensuring good water flow is paramount for a clean wash.
The Exterior of the Drum and Heater Element
The heating element, responsible for heating water in machines that offer hot washes, can accumulate limescale, especially in hard water areas. This reduces efficiency and can eventually lead to failure. Regular hot washes with vinegar help to mitigate limescale. The exterior of the drum itself, though less accessible, can also develop residue. The high-temperature cleaning cycles are designed to address this build-up on the drum's interior surfaces.
If you live in a hard water area, consider using a limescale-reducing washing machine cleaner periodically.
Considering Specialized Cleaners
For those who prefer not to use vinegar or bicarbonate of soda, commercially available washing machine cleaners are a viable option. These are specifically formulated to tackle common issues like limescale, detergent build-up, and bacterial growth. They often come in tablet or liquid form and are used by running an empty hot cycle. When choosing a cleaner, look for one that addresses your specific concerns, such as odour removal or limescale reduction. Always follow the manufacturer's instructions precisely. Regardless of the cleaning agent used, the principle remains the same: a clean interior leads to cleaner clothes and a healthier appliance.
When to Call a Professional
While most internal cleaning tasks for your washing machine can be handled at home, there are situations where seeking professional help is the most sensible course of action. Attempting complex repairs or cleaning without the right knowledge or tools can potentially cause more damage or lead to safety hazards. Understanding when to step back and let an expert handle it is part of responsible appliance ownership.
Persistent, Unexplained Odours
If you have diligently followed the cleaning steps, including running hot cycles with vinegar and bicarbonate of soda, cleaning the seal and filter, and maintaining proper usage habits, yet a strong, unpleasant odour persists, it may indicate a deeper issue. This could involve build-up within internal pipework, a problem with the pump, or even a component failing. A technician can diagnose and resolve these more complex smell sources.
Mechanical Issues or Unusual Noises
Any new, loud, or unusual noises during operation – grinding, clanking, excessive rattling, or humming – should not be ignored. These often signal problems with the drum bearings, motor, suspension, or something lodged in the pump that you cannot access or safely remove. While a simple filter clean might resolve minor issues, significant mechanical problems require professional diagnosis and repair.
Drainage or Spin Cycle Problems
If your washing machine fails to drain properly, leaves excessive water in the drum after the cycle, or experiences issues with the spin function, it could be due to a blockage in the drain hose or pump that a standard filter clean cannot resolve. It might also indicate a fault with the pump motor or the machine's control system. These are best addressed by a qualified engineer who can inspect the entire drainage path and relevant components.
Always unplug the washing machine from the mains power before attempting any internal checks or cleaning beyond what's described in your appliance manual.
Error Codes or Malfunctions
Modern washing machines often display error codes on their control panels when a fault is detected. If your machine shows an error code related to drainage, heating, or motor function, consult your manual to understand its meaning. If the manual suggests a problem beyond simple user intervention, or if the code persists after trying basic troubleshooting, it’s time to call a professional. They have the diagnostic tools and expertise to interpret these codes accurately.
Knowing your limits with appliance maintenance is key to longevity.
