How much energy does a washing machine use?
The washing machine is a vital household appliance, but it can waste energy if not used properly. In this article, we'll explain your washing machine’s energy consumption in watts, explore the factors affecting its usage, and share practical tips to optimise its performance. This way, you can get the most out of your machine without impacting your electricity bill or your wallet—while still achieving clean, efficient laundry!
Why do some washing machines use more electricity than others?
Several factors can influence a washing machine’s wattage (W) consumption. Potential reasons can include the model, load capacity, selected wash cycle, the technology it uses, or its energy efficiency rating. Therefore, a standard washing machine may consume between 1,000 and 2,500 watts per cycle. Yes, that’s a wide range, but it’s because not all machines operate the same way. Some models heat water more efficiently or feature inverter motors that optimise energy use. Older machines tend to consume more electricity, as they lack the advanced components or technology that boost efficiency.
A cold wash cycle may only use between 500 and 800 watts, while a hot cycle (around 60°C) can exceed 2,000 watts. Heating the water is the main driver behind a washing machine’s increased wattage consumption. The built-in heating element draws significant power, in addition to the energy needed to spin the drum at high speeds for both washing and spinning—further increasing the total electricity consumption.
Other factors that affect your washing machine’s energy use
The duration of the wash cycle, spin speed, laundry load, energy efficiency rating, motor technology (conventional vs. inverter), and even the machine’s condition all play a key role in determining whether your laundry will come out clean—and so will your budget.
Load capacity
The higher the capacity, the more energy a washing machine will use. Models with an 8 kg or larger capacity typically draw more electricity. However, they can also be more efficient if used correctly by doing fewer wash cycles. More clothes per cycle means fewer cycles overall.
Wash programmes
The number and duration of cycles, along with water temperature, significantly impact energy use. Shorter cycles and cold water use less energy than long, hot washes.
Energy efficiency
Washing machines rated A are the most efficient. Modern machines display an energy label ranging from A (most efficient) to G (least efficient). Class A or higher (A+ and A++) ensures lower energy use per wash cycle.
Technology and age
New-generation machines equipped with load sensors and inverter motors are quieter, more efficient, and longer-lasting than older models. Machines over 10 years old may consume twice as much electricity as newer models.
Washing machine models that consume more energy
As mentioned earlier, older models or those with an energy rating below A typically consume more watts. But aside from these specifications, machines that are incorrectly programmed will also consume more energy. That’s why it's highly recommended to learn how your appliance works, its capabilities, and different modes of use; otherwise, you could be wasting its full potential and efficiency.
Some high-consumption models include machines that don’t adjust energy use based on load size automatically or those without eco-friendly programmes. Industrial or large-capacity machines designed for performance over efficiency normally demand more electricity too.
We can also find washer-dryer combos, machines lacking energy efficiency that may consume over 2,500 watts per cycle, and machines with powerful heating elements that reach very high water temperatures. Lastly, we have large-capacity machines without load sensors—using them for small loads results in wasted energy.
How to reduce your washing machine’s energy consumption
There are many habits and strategies you can implement to lower your washing machine’s energy use. By doing so, you’ll not only save money but also help the environment:
- Wash with cold or low-temperature water: setting the wash to 30°C instead of 60°C can cut energy use by up to 40%.
- Use your machine’s full capacity: load it fully without overstuffing to avoid running multiple cycles.
- Choose eco or short cycles: eco programmes may last longer but use less water and energy overall. Skip the prewash unless necessary: only use it for heavily soiled laundry.
- Perform regular maintenance: clean the filter, check the drum and hoses, and make sure everything runs smoothly to maintain efficiency.
- Adjust spin speed as needed: higher spin speeds increase energy consumption slightly, so use them wisely depending on your load.
- Wash during off-peak hours: if you have a time-of-use electricity plan, take advantage of off-peak times to save on your bill.
Technology that helps you monitor your washing machine's energy use
There are now apps, smart plugs, and systems that help you track and manage the energy use of your appliances, including washing machines:
Smart plugs: some come with energy monitors that show real-time wattage consumption. They also let you schedule start and stop times.
Home energy monitors: these plug in between the machine and wall outlet to track total and per-cycle energy use.
Mobile apps: smart washing machines can be monitored and controlled through apps on your phone or tablet.
Smart home systems: connecting your washing machine to your home’s smart grid allows you to manage its energy use alongside your other household appliances. These systems help you pinpoint when and why your washing machine consumes more energy and allow you to adjust its use accordingly.

It’s pretty clear that a washing machine’s electricity consumption depends on many factors: its age, water temperature (hot or cold), its energy rating (A, B, C, etc.), whether your electricity tariff suits your daily needs, and your monthly laundry frequency.
Crucially, you have multiple options to reduce your appliance’s energy use. This post has shared how technological tools, responsible usage strategies, and simple adjustments to your washing habits can make a big difference. Because laundry isn’t just about ensuring your clothes are clean—it’s about doing it efficiently, affordably, sustainably, and without harming the planet.
