How Many Amps Does a Washing Machine Use? Unveiling the Electrical Secrets of Your Appliance

When it comes to understanding the electrical current of your washing machine, it’s crucial to know the amperage it requires. This article aims to unravel the mystery and provide you with valuable insights to make informed decisions about your appliance’s power consumption.

The Basics of Amps and Washing Machines

Assuming your washing machine is connected to a standard 120v outlet, the amperage typically ranges from 5 to 15 Amps. However, this may vary depending on factors such as wattage rating, washer type, motor size, and age. The general rule of thumb is that the amperage of a standard washer does not go beyond 20 Amps, but it is advisable to opt for a 20 Amp circuit breaker to ensure optimal performance.

To determine your washing machine’s amperage, you can divide its wattage rating by the outlet voltage (120v for standard washers). This straightforward calculation allows you to have a clear understanding of your appliance’s power requirements.

Factors Influencing Amps Requirements

1. Wattage Rating

The wattage rating of your washing machine plays a crucial role in determining its amperage requirements. As a general principle, the higher the wattage, the higher the amperage. You can find the wattage rating on your machine’s sticker and calculate the amperage by dividing it by the socket voltage (usually 120v).

2. Type of Washing Machine

Top-loading and front-loading washers have different energy consumption and amperage requirements. While top loaders typically use 12 to 15 Amps, front loaders need 11 to 20 Amps. The wattage also varies, with front loaders requiring 700 to 1500 watts and top loaders needing 900 to 1200 watts.

3. Washing Machine Motor Size

The size of the washing machine’s motor directly affects its amperage requirements. Larger capacity washers with more powerful motors generally require more power to operate.

4. Age of the Washing Machine

Older washing machines tend to use more energy due to their less energy-efficient designs. Newer models, on the other hand, are more energy-efficient and have lower amperage requirements.

5. Water Level

The water level setting in your washing machine can also impact its energy consumption. Higher water levels result in increased energy usage, while lower levels save energy. It is advisable to find a balance by opting for a medium setting to ensure effective cleaning while minimizing energy consumption.

6. Type of Cycle (Cold vs. Hot Cycle)

Washing machines that operate with hot water consume more energy than those using cold water. If your washer receives water from a hot heater, it may require fewer amps.

Saving Energy While Using Your Washing Machine

Now that you understand the factors influencing your washing machine’s amperage requirements, here are some tips to reduce energy consumption:

  • Choose the cold cycle: Reserve hot water for heavily soiled laundry, and opt for cold water for regular washing to save energy.
  • Opt for eco mode: Use the eco mode setting to conserve both energy and water, even though it may take longer.
  • Go low speed: Lower the spin speed setting to reduce power usage.
  • Bypass the spin cycle: For certain garments that dry quickly, bypassing the spin cycle can save energy.
  • Reduce the water level: By lowering the water level, you can minimize energy consumption for heating water without compromising washing quality.
  • Go full load if possible: Utilize the full capacity of your washer to maximize energy efficiency.
  • Take advantage of the cool-down cycle: Some dryers have a cool-down cycle that utilizes residual heat to dry clothes completely, reducing energy usage.
  • Use quick wash: Quick wash settings reduce both water and electricity consumption by shortening the wash time.

And there’s more! By using the correct detergent, presoaking heavily stained clothes, switching off the washer when not in use, and upgrading to an energy-efficient washer, you can further decrease your energy consumption.

Remember, understanding your washing machine’s amperage not only helps you make informed decisions but also allows you to take proactive steps towards reducing your energy costs. For more helpful articles on various topics, visit 5 WS.


In conclusion, a typical washing machine requires 5 to 15 Amps of electrical current, depending on various factors. While a dedicated 15 Amp circuit usually suffices, if you plan to connect a dryer, a 20 Amp circuit is necessary. By applying the tips shared in this article, you can save energy and make your laundry routine more eco-friendly.
