Wondering if does dishwasher use a lot of electricity? We’ve got the answer to whether dishwashers use a lot of electricity.

When it comes to doing the dishes, there’s no question that dishwashers are more efficient than washing them by hand. But how much electricity do dishwashers really use?

A new study by the Natural Resources Defense Council (NRDC) found that the average dishwasher uses about 637 kilowatt-hours of electricity per year, which is about the same as a new refrigerator.

How Much Electricity Does A Dishwasher Use?

Electricity Usage of a Dishwasher Calculator

The average dishwasher uses about 1,200 watts of power. That’s about one-tenth of the average household’s total energy usage. The average dishwasher cycle lasts for about an hour. So, if you use your dishwasher for one hour a day, that’s about 30 kWh of electricity per month or about 360 kWh per year.

Dishwashers have come a long way in recent years, becoming more energy efficient. Newer models use less water and electricity than older models. Some newer models even have sensors that can detect how much water is needed to clean the dishes and will adjust the cycle accordingly.

While it’s true that dishwashers are more energy efficient than they used to be, there are still some things you can do to reduce their power usage even further.

Why Do Dishwashers Use So Much Electricity?

Dishwashers are one of the most energy-efficient appliances in the home. But they still use a lot of electricity. Here’s a look at some of the factors that contribute to a dishwasher’s high power usage.

The first factor is the size of the dishwasher. A dishwasher has to be big enough to hold all of your dishes, and that means it uses a lot of electricity to run. Secondly, dishwashers use a lot of water.

They have to heat up that water to get your dishes clean, and that takes energy. Finally, dishwashers have a lot of moving parts. The pumps and motors that move the water around use electricity, too.

So why do dishwashers use so much electricity? It’s because they’re big, they use a lot of water, and they have a lot of moving parts.

Are There Ways To Reduce dishwasher Electricity Usage?

Are there ways to reduce dishwasher electricity usage? You bet there are! Here are a few suggestions:

  1. Use less water: One of the biggest draws on your dishwasher’s power is heating up all that water. So, use less water and your dishwasher will use less power.
  2. Scrape, don’t rinse: Pre-rinsing your dishes before loading them into the dishwasher is a waste of water and energy. Just scrape off the food and let the dishwasher do its job.
  3. Don’t overload: Overloading your dishwasher can make it work harder and use more energy. So, be mindful of how much you’re putting in and make sure everything fits properly.
  4. Use the right temperature setting: If you use too high of a temperature setting your dishwasher might have to work harder to get your dishes clean. So, try using a lower setting and see how it works for you.
  5. Don’t pre-rinse your dishes: While it’s tempting to pre-rinse your dishes, doing so can make your dishwasher work harder.


How many watts does a dishwasher use?

Dishwashers can use a lot of energy. The average dishwasher uses about 1800 watts per cycle. But some dishwashers use as much as 2400 watts.

So how much energy does your dishwasher use? The answer depends on a few factors, including the type of dishwasher, the size of the unit, and the number of cycles you run per day. But on average, a dishwasher uses about 1 kilowatt-hour (kWh) of electricity per day.

That’s about 30 kWh per month or 365 kWh per year. If you have an energy-efficient dishwasher, it may use as little as 1200 watts per cycle. But if you have an older model that isn’t as efficient, it could use more than 2400 watts.

What is the best time to run the dishwasher?

When it comes to turning on your dishwasher, the best time to do this is late at night. There are many factors that play a part in this, including energy usage and noise levels.

During the day, dishwashers are competing with other appliances for electricity. This can cause your energy bill to skyrocket. However, at night there is less demand for power so your dishwasher will cost you less to run.

In addition, running your dishwasher at night will help you avoid making too much noise during the daytime hours. This is especially important if you live in an apartment or condo where noise levels can be a nuisance to your neighbors.

Is using the dishwasher more energy efficient?

When it comes to dishwashing vs handwashing, the idea that using an electrical appliance could save energy is counterintuitive. But when you consider that the average dishwasher uses less water and energy than washing dishes by hand, it starts to make a lot of sense.

Washing dishes by hand typically requires about 27 gallons of water, while a dishwasher only uses 4 gallons. That’s a big difference! And when it comes to energy use, the average dishwasher uses less than half the amount of energy as washing dishes by hand.

So, if you’re looking to be more energy efficient, ditching the sponge and reaching for the dishwasher is definitely the way to go.

How much electricity does a dishwasher use?

How much electricity does a dishwasher use? The answer to this question depends on several factors, such as how often you run it, the cycle you choose, and the time of day you put it on. Your electricity usage will also be affected by your contracts with your energy provider.

Generally speaking, dishwashers use between 1 and 2 kWh of electricity per cycle. However, if you run your dishwasher multiple times per day or choose longer cycles, your electricity usage will be higher.

You can save money on your electricity bill by running your dishwasher during off-peak hours when energy rates are lower. You can also reduce your electricity usage by choosing shorter cycles and running your dishwasher less often.


Yes, dishwashers use a lot of electricity. They are also one of the most energy-efficient appliances in your home. If you are looking to save money on your energy bill, consider investing in a dishwasher.
