How Many AMPs Does a Washing Machine Use? (Explained!)

Given the frequency of usage, you may want to know your washing machine’s electric current, which brings us to the term Amperage (Amp). In that case, how many amps does a washing machine use?

Assuming that the washing machine is connected to a 120v outlet, a standard machine uses 5 – 15 Amps depending on factors like wattage rating, washer type, motor size, and age, among others. 

So, the Amperage of a standard washer doesn’t go beyond 20 Amp. But when it comes to the breaker’s Amperage, it’s advisable to go for 20 Amps.

The easiest way to know your washing machine’s Amperage is to divide its wattage rating by the outlet voltage (120v for standard washers).

Overall, there are many ways to cut down on your washer’s energy but which I’ll explain later. But first, let’s discuss the factors determining your washer’s Amperage.

how many amps does a washing machine use

In a rush? Below is a quick table to help you know your washer’s Amp requirements according to their wattage rating.

Typical Washing Machine Wattage (Watts) Vs. Amperage (Amps)

Wattage Amperage 
400 watts 3.3 Amps 
500 watts 4.2 Amps 
600 watts 5.0 Amps 
700 watts 5.8 Amps 
800 watts 6.7 Amps 
900 watts 7.5 Amps 
1,000 watts 8.3 Amps 
1,200 watts 10.0 Amps 
1400 watts 11.7 Amps 

Factors Determining a Washing Machines Amps Requirements 

Generally, below are the key determiners of washing machines Amps:

1. Wattage Rating 

The wattage, which measures the power consumption, hugely determines your washer’s Amperage requirements. Typically, the higher the washer’s wattage requirements, the higher the Amps. 

Remember, you can get your washer’s wattage rating from its sticker, and once you get it, divide it by the socket voltage (normally 120v). That brings us to the formula below:

Amps = Watts ÷ Volts 

So, for a standard washer (one that needs 400 – 1400 watts and running on a standard socket (120v), the Amps requirement, as highlighted in the above table, is below 15 Amps. 

For example, if you have a 600W washer, divide by 120 v (for the outlet) and get 5 Amps. And if the washer’s wattage rating is 1200 watts, you’ll get 10 Amps. 

2. Type of Washing Machine 

Top-loading and front-loading washers have different energy consumption and electric current requirements. For example, while a top loader only uses 12 – 15 Amps, the front loaders need 11 – 20 Amps. 

The same goes for the wattage, where the front loader requires 700 – 1500 watts while a top loader requires 900 – 1200 watts. Again, that applies to standard washers.

3. Washing Machines Motor Size

More powerful washers (usually bigger capacities) require more power to run. In the case of the Amperage, the bigger the motor size, the bigger the Amperage.

4. Age of The Washing Machine 

Expect an old washer to use more energy to run. That’s because these washers don’t focus on saving energy. Newer models are, however, more energy efficient, meaning their Amperage requirement is low. 

5. Water Level 

While raising the water level promises a better wash, it comes at the expense of more energy consumption. The lower the water level setting, the less energy is used. 

But since a low water level may not clean the clothes effectively, it’s advisable to go for a medium setting. 

6. Type of Cycle (Cold Vs. Hot Cycle)

Washing with hot water demands more energy consumption than washing with cold water. Expect the washer to require fewer Amps if it’s receiving water from a hot heater. 

And How Many Watts Does a Washing Machine Use?

A standard washer uses about 400 – 1400 watts, depending on type and style. For example, while a top-loading washer requires 900 – 1200 watts, a front-loading washer requires 700 – 1500 watts. 

Note that you can always calculate your washer’s wattage by multiplying the Amperage by the socket voltage (normally 120v). In that case, here’s a table showing the wattage requirements depending on the washer’s Amperage.

Amperage Wattage 
4.2 Amps 500 watts 
5.0 Amps 600 watts 
6.7 Amps 800 watts 
8.3 Amps 1,000 watts 
10.0 Amps 1,200 watts 
11.7 Amps 1400 watts 

Note that you can also get your washing machine’s wattage from its accompanying sticker.

Are Washing Machines 15 Or 20 Amp?

A laundry room needs a dedicated circuit that’s the tallest 20 Amps to cater to the washing machine and the dryer. Remember, while the washer needs an outlet of 15 Amp, a dryer requires up to 20 Amp.

According to the National Electric Code (NEC), laundry appliances should have dedicated circuits, which applies to washing machines. 

Such a circuit ensures your washer receives enough power and does not suffer any overloading issues. In that case, the circuit breaker won’t trip, and the fuse won’t blow up. 

Can a washing machine be on a 15 amp circuit

So, Can A Washing Machine Be On A 15 Amp Circuit?

Washing machines can work on a 15 Amp 120v circuit or a 20 Amp 120v circuit. It depends on the washing machine type and if you intend to plug in a dryer. 

In the case of the latter, then consider a dedicated 20 Amp 120v circuit. However, if you have no plans to plug in a dryer, you can use a 5 Amp 120 v circuit. 

But How Many Amps Does a Washing Machine Use? Your 3 Options

After looking at the factors determining a washing machine’s Amperage requirements, we can conclude that there are three categories of washers:

  • 10 Amps washers (those that require more than 10 Amps)
  • 15 Amps washers (those requiring more than 10 Amps but less than 15 Amps
  • 20 Amps washers (those requiring up to 20 Amps)

Let’s explore the three options:

10 Amps Washing Machine Count 

Though not many, some washing machines only require 10 Amps to run or less. These washers are mostly older models, but a few are designed that way. 

15 Amps Washing Machine Count

The 15 Amps category forms the majority of the washers. Most washers are designed to use up to 15 Amps and therefore need a dedicated 15 Amp circuit. The exception is when a dryer needs up to 20 Amps. 

20 Amps Washing machine 

While the washing machine needs a 10 – 15 Amp power supply, you may have to stop the circuit supply up to 20 Amp if you have a dryer. A 20 Amps circuit will also prevent the circuit breaker from tripping. 

How to Save On Power When Using the Washing Machine 

Generally, you can reduce your washing machines power consumption using these tips:

  • Choose the cold cycle – You don’t have to use hot water whenever you want to do laundry. The more you wash with hot water, the more power you use, and for that reason, reserve the hot water only for the filthiest laundry and those with heavy stains. As for others, wash them with cold water. 
  • Opt for eco mode – Eco mode saves you energy and water. The only issue is that it’s slower. So, if you don’t have a problem waiting a bit longer, Eco mode is worth pursuing. 
  • Go low speed – The higher the spin speed, the more power the washer uses. You can, however, reduce the power use by setting the washer at low speed. 
  • Bypass the spin cycle – Some clothes, especially lighter ones, don’t need any spinning as they dry quickly. So, you can always bypass the spin cycle to save on energy. 
  • Reduce the water level – A higher water level requires more power to heat up, unlike a low water level. So, lower the water level instead of heating a lot of water when you don’t need that. The water level shouldn’t, however, be too low. 
  • Go full load if possible – Your washer uses the same amount of power to wash clothes regardless of how complete the drum is. So, instead of only filling up the drum ½ full, fill it to about 3/4 full. Leave a small allowance for the clothes to turn. 
  • Take advantage of the cool-down cycle – Some dryers have the cool-down cycle, which allows the clothes to dry completely using the heat already in the dryer. So, while this has nothing to do with the washing machine, it helps to save energy on the dryer. 
  • Use quick wash – Quick wash allows you to reduce the wash time by at least 15 minutes. Not only that, it saves energy since the washer runs for less time.
Are washing machines 15 or 20 amp

And More

  • Use the correct detergent – Consider using an HE detergent and avoid putting too much of it to prevent excess suds. Excess suds force the washer to use more power and water to clean off the soapy deposits.
  • Presoak – If your clothes are heavily stained or soiled, you don’t have to put them into the washer and start washing them right away. No! You can presoak them in water for about 30 – 60 minutes before washing them with the machine. 
  • Switch off the washer when not in use – You don’t have to leave the washer on when you are not using it. Just turn it off to save on energy. 
  • Upgrade to an energy-efficient washer – Lastly, you can upgrade to a more energy-efficient washer than you already have. Such a laundry machine will save you energy, especially after employing the above-shared tips.
