Buying a washing machine isn’t just about picking the right size or brand. One of the most important things you need to consider is the washing machine energy rating. Energy efficiency isn’t just a nice-to-have—it can significantly affect your electricity bills, your household’s environmental footprint, and even your long-term satisfaction with your appliance.
But what exactly is a washing machine energy rating, and why should it matter to you as a homeowner? In this article, we’ll break it down in a simple, practical way.
What Is a Washing Machine Energy Rating?
The washing machine energy rating is part of Australia’s Energy Rating Labelling system. It’s designed to help consumers compare the energy efficiency of different appliances at a glance.
On most new washing machines, you’ll see a label with stars ranging from one to six or seven, depending on the product. More stars mean higher energy efficiency.
Here’s what the label tells you:
- Energy consumption: How much electricity the machine uses per year.
- Water consumption: How much water the machine uses per wash cycle.
- Capacity: The maximum weight of clothes the machine can handle per load.
- Other efficiency metrics: Some labels also show spin speed and washing performance.
Essentially, the energy rating gives you a snapshot of how much running the machine will cost you and how environmentally friendly it is.
Why Does the Washing Machine Energy Rating Matter?
You might wonder, “Does it really make a difference?” The answer is yes. Here’s why:
1. Save Money on Electricity Bills
A higher-rated washing machine uses less energy. Over time, this can result in noticeable savings. For example, a six-star machine could use up to 40% less electricity than a three-star model.
2. Reduce Your Environmental Impact
Using less electricity isn’t just good for your wallet—it’s also better for the environment. Efficient machines reduce greenhouse gas emissions and help conserve natural resources.
3. Water Efficiency
Many energy-efficient machines are also water-wise. Lower water consumption means less strain on your household’s water supply and lower water bills.
4. Long-Term Appliance Performance
Machines with higher energy ratings often come with better technology, like efficient motors and advanced wash cycles. This can extend the life of your washing machine and improve washing performance.
How Are Washing Machines Rated?

You might be curious about how these stars are determined. The rating is calculated using a standardised formula that considers:
- Energy use per wash cycle: Measured in kilowatt-hours (kWh).
- Water use per wash cycle: Measured in litres.
- Load size: Machines with larger capacities are evaluated based on their energy and water use per kilogram of laundry.
These ratings are regulated by Energy Rating Australia, and labels must be displayed on all new machines sold. This ensures transparency and allows homeowners to make informed choices.
Top Questions Homeowners Ask About Washing Machine Energy Rating
1. Is a Higher Star Rating Always Better?
Generally, yes. More stars usually mean more energy efficiency. But there are a few exceptions:
- Cost vs. Savings: Higher-rated machines can be more expensive upfront. You need to calculate how long it will take to recoup the extra cost through energy savings.
- Household Needs: If you don’t do much laundry, the difference in energy usage may be less significant.
2. How Much Can I Really Save?
Your savings depend on how often you wash clothes, the type of load, and electricity rates in your area. Choosing a higher-rated machine can make a noticeable difference. For instance, upgrading from a three-star to a five-star washing machine can reduce water consumption by around 18 kilolitres per year and lower household bills by roughly $54 annually.
If you go even higher to a six-star model, energy use drops further, and total annual savings on electricity and water for a typical household can reach $100–$200. Over the lifetime of the appliance, these reductions can add up to hundreds of dollars in savings, making energy-efficient washing machines a smart investment.
3. Does Washing Machine Size Affect Energy Rating?
Yes. Larger machines naturally use more water and electricity per cycle, but efficiency is usually measured per kilogram of laundry. So, a large machine with a high star rating can still be more efficient than a small, low-rated model.
4. Are Front Loaders More Efficient Than Top Loaders?
In many cases, yes. Front-loading machines often use less water and electricity because they tumble clothes rather than submerge them fully. However, energy rating labels help you compare both types fairly.
Tips for Choosing an Energy-Efficient Washing Machine
When shopping for a new washing machine, it’s worth looking beyond just the star rating. Here’s a closer look at what to consider:
1. Look Beyond the Stars
While the star rating is a quick guide to energy efficiency, there are other important details on the label:
- Annual energy consumption (kWh/year): This shows the estimated electricity usage over a year under standard testing conditions. Two machines may have the same star rating but different annual energy use, so this number gives you a clearer idea of running costs.
- Water consumption per cycle: Some machines use more water than others, even with a similar star rating. Lower water usage saves money and is better for the environment, especially in regions prone to water restrictions.
- Spin efficiency and speed: A higher spin speed extracts more water from your clothes, reducing drying time and energy needed if you use a dryer. Consider the spin efficiency rating if you often tumble-dry your laundry.
2. Match the Capacity to Your Household
Choosing the right size machine is critical:
- Too large: Using a machine bigger than your usual laundry load wastes energy and water because smaller loads don’t use the full capacity efficiently.
- Too small: A machine that’s too small may require multiple cycles, which can increase electricity and water use over time.
- Typical capacities: A family of four often benefits from a machine with 7–10 kg capacity, while singles or couples may be fine with 5–6 kg.
3. Consider Wash Programs
Modern washing machines come with a variety of programs designed to improve efficiency:
- Eco-wash cycles: These typically use lower water temperatures and less energy while still cleaning effectively.
- Quick wash or express cycles: Great for small loads, reducing electricity and water use.
- Specialty cycles: Some machines have wool, delicates, or hygiene cycles that optimise water, spin, and temperature for specific fabrics without overusing energy.
Even a machine with a moderate star rating can be very efficient if it has the right programs for your typical laundry.
4. Check for Incentives
Energy-efficient appliances may qualify for rebates or discounts:
- State-specific incentives: Some states, like Victoria or New South Wales, occasionally offer cash-back rebates for high-efficiency washers.
- Energy provider schemes: Electricity providers may also provide discounts or vouchers for purchasing appliances that reduce household energy consumption.
- Timing purchases: Buying during promotions or government incentive periods can offset higher upfront costs.
5. Think Long-Term
A higher-rated machine might cost more initially but saves money over its lifetime:
- Total cost of ownership: Consider purchase price, estimated electricity and water bills, and potential repair or maintenance costs.
- Durability and reliability: High-efficiency machines often have better motors and advanced features, which may reduce the need for repairs.
- Resale value: If you plan to sell your machine or move, efficient machines can be more appealing to buyers.
How to Maximise Efficiency Once You Have Your Machine

Even the most energy-efficient washing machine won’t save you money if it’s not used correctly. By adopting smart washing habits, you can make the most of your machine’s energy rating and reduce both electricity and water usage. Here are some practical strategies:
Wash Full Loads
Running half-empty loads wastes both electricity and water, reducing the efficiency of your appliance.
If you only have a few items, many modern machines offer half-load or eco cycles designed to adjust water and energy usage for smaller loads. Using these settings ensures you’re not overusing resources while still getting your clothes clean.
Use Cold Water Cycles
Heating water is the largest contributor to energy consumption in washing. By using cold water cycles, you can dramatically reduce electricity use.
Most modern detergents are formulated to clean effectively at lower temperatures, so lightly soiled clothing and everyday items can be washed in cold water without compromising cleanliness. For heavily soiled items, a warm wash may still be necessary, but using cold water wherever possible is a simple way to cut costs.
Avoid Excessive Detergent
Using too much detergent can create excess suds, which often requires additional rinses and uses more water and energy.
Follow the manufacturer’s guidelines for the correct amount of detergent based on your load size and soil level. High-efficiency detergents are a good choice for energy-efficient machines, as they perform well with lower water volumes and prevent residue build-up in the drum.
Maintain Your Machine Regularly
Regular maintenance ensures your washing machine continues to operate efficiently and prolongs its lifespan.
- Clean filters and lint traps: Removes debris that can reduce water flow and machine performance.
- Check hoses: Replace hoses showing signs of wear or leaks to prevent water wastage.
- Descale if needed: In areas with hard water, mineral build-up can affect energy efficiency and washing performance.
- Leave the door ajar: Allowing the drum to dry after washing prevents mould growth and keeps the interior in good condition.
Optimise Spin and Drying
Using the highest spin speed suitable for your fabrics helps remove more water from clothes, reducing drying time and energy consumption if you use a dryer.
Even when air-drying, a thorough spin cycle ensures clothes dry faster, preventing the need for extra cycles or extended tumble drying. If using a dryer, always spin efficiently first to save on electricity.
Plan Wash Cycles Smartly
Organising your laundry can make a significant difference in energy efficiency:
- Combine similar fabrics and colours: Washing similar items together avoids extra cycles and ensures even cleaning.
- Use off-peak hours: If your energy provider offers differential rates, doing laundry during off-peak times can lower electricity costs without changing your washing habits.
By following these tips, you can maximise the efficiency of your washing machine, get the most out of its energy rating, and save both money and water in your household.
