Not only will knowing the power consumption of your electronics help to keep your bills from going too high, but it also helps you to dedicate outlets to the ones who need them.

You may want to buy a dishwasher but may be concerned about its power consumption. Thus, how many amps top dishwashers use is a question you may ponder on.

A dishwasher uses about ten amps of current on average. The amount of amps a dishwasher will use is dependent on the brand of dishwasher you are using. But no matter the brand of dishwasher you are using, the difference in the amp requirements is not much, and on average, the amp requirement is almost the same.

Top 10 Dishwashers And Their Power Requirements?

There are different brands of dishwashers. And so are the differences in the amounts of current they need to function properly. When you compare USA brands of dishwashers and brands of other countries, you’ll notice that their features determine the current dishwasher requirements.

Dishwashers often consume a lot of energy. But this energy range is usually from 6.6 amps of current to 15 amps of current, especially when the dishwashers are from the USA. A list of 10 top dishwasher brands in the USA with their amps requirements are given below:

1. Bosch Dishwashers

This renowned brand has dishwashers that typically draw a current of 12 amps.

How Much Power Does A Dishwasher Draw?

Dishwashers often draw a lot of power when in use. Most often, the power requirement ranges from 1200 to 2400 watts.

How much power a dishwasher draws is dependent on some factors. Some of these factors include: how frequently the dishwasher is used, the times of the day the dishwasher is used, and the brand of dishwasher you are using.

How a dishwasher works are based on the factors that have been listed above. For example, power consumption may be less when running in the early hours of the day because the wires would not have expanded as they would when the day is hot, and the wires’ expansivity increased.

When a dishwasher is frequently used, the wires expand, and more power flows, causing an increment in the power uptake of the dishwasher.

Because the more the dishwasher is working, the more power it would be consuming. When the dishwasher runs for a very long period and then the temperature of the day increases, power consumption will also be increased.

It is very important to know that the power consumption is also dependent on the brand of dishwasher you are using. While most dishwashers do not require high power to function, others do not function properly without a sufficient power supply. But with this, the highest power requirement for a dishwasher is 2400 watts.

Does A Dishwasher Use A Lot Of Electricity?

A dishwasher does not use a lot of electricity. A dishwasher’s electricity is dependent on its features, but it is only the water it heats that consumes electricity. On average, dishwashers often require an electricity supply of up to 1.8 kilowatts. Its electricity consumption is dependent on the time of the year and the time of the day.

In summer, using hot water is normally reduced due to the hotness of the weather. Less electricity is required to run a dishwasher by this time of the year because hot water would be reduced. In cold weather, the dishwasher will use more electricity because more water will be heated.

Also on cold days, hot water will be required for use thereby increasing the electricity usage. This is, however, different on hot days.

This is because the weather will be hot and hot water will not be required for use. Hence, electricity usage will be low. Sometimes it is also dependent on the type of dishes that are to be cleaned.

Another factor is the part of the country or the area you are living in. For places with often cold weather, more electricity will be used for dishwashers, and in places with warm and hot weather, less hot water is required.

Hence, less electricity is needed when using dishwashers except when the dish requires hot water to be clean. The brand of the dishwasher will also determine the amount of electricity it will consume.

Most often, dishwashers do not use much electricity, but some brands may consume a lot of electricity while the dishwasher runs even without heating water. Meanwhile, for other dishwashers, even with water being heated, they do not consume much electricity.

Should You Run A Dishwasher Every Day?

You can run dishwashers every day depending on how often you need them for use. There is no rule to determine how often you should use a dishwasher. But as is well known, increasing its usage may shorten the lifespan of the dishwasher.  Also, it will cost more in terms of electricity consumption and water use, especially when oily dishes are cleaned.

When there is a constant electricity supply and water supply, You can run a dishwasher every day. The only thing that can affect the use of a dishwasher is electricity and water supply. When these two factors are available, you can use a dishwasher daily.

Also, if there is nothing wrong with the dishwasher, you can use it every day. Something that should be considered when using a dishwasher should be the number of dishes done.

It would be nice if, after using a dishwasher to do a lot of dishes, it is allowed to stay for some time, either for a day or two, before using again. So as not to cause wear and tear of the dishwasher and reduce its lifespan.

When a lot of dishes are not done, a dishwasher can run daily without being affected. But while running a dishwasher, you should always remember that without full electricity and full water supply, it is dangerous to be using it because it will cause damage to the machine.

When the electricity and water supply aren’t stable, it would be best not to use the machine.

Is It Better To Run A Dishwasher Or Wash By Hand?

It is better to use a dishwasher while doing dishes because of the stress the dishwasher will save you and your time while washing your hands. A dishwasher uses less water when doing dishes when compared to the amount of water used when washing by hand. Therefore it is always better to wash with a dishwasher.

It is only better to use hands to wash is when the dishwasher is not fully loaded. When the dishes are not much, it is preferable to use hands in washing the dishes than using a dishwasher because it is better and more economical to use a dishwasher when it is fully loaded.

Also, using a dishwasher is dependent on the type of dish. Dishwashers can not wash some dishes.

Else they may be damaged; such dishes are better hand washed. When there is no full power supply to a dishwasher, it is preferable to wash by hand rather than using the dishwasher to not damage the dishwasher.


The power requirements for a dishwasher are dependent on the size you have. But most specifically, the dishwasher brand also contributes to the number of amps it requires to function properly.

Nonetheless, a dishwasher’s average amp consumption capacity is often ten amps, irrespective of the brand.
