With the fast-paced lifestyle in Hong Kong, a washer has become an essential household appliance. Whether you're a busy professional or part of a large family, laundry is a daily or weekly necessity. However, washers consume a significant amount of electricity, especially with prolonged and frequent use, which not only increases your electricity bills but also places an extra burden on the environment.
In a city like Hong Kong where electricity costs are relatively high, learning how to reduce washer energy usage can help lower household expenses and contribute to environmental protection. This article provides a comprehensive energy-saving guide for washers, covering purchasing, usage, maintenance, and other practical tips.
Buying an Energy-Efficient Washer
1. Understand the Energy Efficiency Label
When purchasing a washer in Hong Kong, the first step is to check the Energy Efficiency Label. According to the Electrical and Mechanical Services Department (EMSD), appliances are rated from Grade 1 to Grade 5, with Grade 1 being the most energy-efficient and Grade 5 the least. Choosing a Grade 1 or 2 washer can significantly reduce electricity consumption. While these models may cost more upfront, the long-term savings on electricity bills can offset the initial price.
2. Consider the Type of Washer
Washers generally fall into two categories: front-loading (drum type) and top-loading (agitator type). Their energy consumption differs:
- Front Load Washer
- Typically more water-efficient but take longer to wash
- Some models feature low-temperature wash and inverter technology to reduce power usage
- Higher spin speed can shorten dryer time, improving energy efficiency
- Top Load Washer
- Shorter wash time but higher water usage
- Usually lack inverter technology, resulting in higher power consumption
If you use a washer frequently and aim to save on electricity in the long run, a front-loading inverter model is a better choice.
Proper Use of Washer
1. Wash Appropriate Loads
The amount of clothing per load is crucial for energy efficiency. Both underloading and overloading reduce performance.
- Too few clothes: washer uses nearly the same amount of water and power, leading to waste
- Too many clothes: longer wash times, reduced cleaning effectiveness, and potential motor damage
It’s best to load your washer to about 80% of its capacity to optimize both cleaning and energy use.
2. Select the Right Washing Cycle
Most washers offer various modes:
- Standard Wash: good for everyday laundry but takes more time
- Quick Wash: ideal for lightly soiled clothes, shorter duration, most energy-efficient
- Heavy Wash: for stubborn stains, but consumes more power and water
Use the quick wash mode for everyday laundry and reserve the heavy wash for heavily soiled items to reduce energy usage.
3. Use Cold Water for Washing
Heating water is the most energy-consuming part of washing. Most detergents are effective in cold water, and modern washers are efficient enough to clean well at low temperatures. Unless dealing with tough stains (like grease or blood), it’s recommended to wash at 30°C or lower, or even in cold water. This can reduce heating energy consumption by over 90%.
Regular Maintenance and Cleaning
1. Clean the Filter
The filter catches lint, dust, and small debris. When clogged, it forces the washer to work harder, consuming more electricity. Clean the filter every 1-2 months to ensure smooth water flow and optimal performance.
2. Keep the Machine Dry
After each use:
- Leave the door open to let the drum air dry and prevent mold
- Wipe the exterior regularly to prevent dust build-up that may affect heat dissipation
A well-ventilated and dry environment helps extend the life of your washer and ensures efficient operation.
3. Clean the Drum Regularly
Over time, detergent residue, bacteria, and limescale accumulate inside the drum, affecting cleaning performance and increasing power consumption. Every 1-2 months, deep-clean your washer using a dedicated cleaner (e.g. Miele MACHINECLEAN Cleaning Agent) or a mixture of vinegar and baking soda to remove odors and grime.

Other Energy-Saving Tips
1. Gather Enough Laundry
Instead of washing small loads daily, gather enough laundry before running a full load. This reduces the number of cycles and lowers total energy use.
2. Air-Dry Your Laundry
Dryers consume 3-5 times more electricity than washers. When weather permits, opt for air-drying, sunlight also acts as a natural disinfectant. If you must use a dryer, use a high-speed spin cycle first to remove excess water and shorten drying time.
In Hong Kong, electricity bills are a major household expense, and washers are among the most frequently used appliances. By choosing an energy-efficient model, using it correctly, maintaining it regularly, and avoiding peak usage times, you can significantly reduce power consumption. These simple habits can make your washer run more efficiently and bring long-term economic and environmental benefits to your life.
