How Many Amps Does a Dishwasher Use? [By Brand]

Thank God for dishwashers! A dishwasher can help you significantly improve your workload on extra-long days or when you host many guests. After your meal, arrange the plates and tweak the appropriate settings, and you are good to go. 

However, dishwashers are somewhat pricey even though they are a great investment. Therefore, you will need to put a couple of things in place to enjoy and even prolong the lifespan of your purchase. 

A good question is how many amps does a dishwasher use. An average home dishwasher will use around 10 amps. Amps usage will vary by brand and model. Knowing the answer will ensure you correctly set up your gadget to avoid short circuits or fire damage. To find out the number of amps the most popular dishwashing brands use, stick around. 

  • Bosch – 12 amps
  • Whirlpool – 10-12 amps
  • KitchenAid – 15 amps
  • Maytag – 15 amps
  • LG – 15 amps
  • Kenmore – 8.2 amps
  • Frigidaire12.5 amps

How Many Amps Does a Bosch Dishwasher Use? 

Bosch Dishwasher uses 12 amps, so consider connecting it to a 15-amp dedicated circuit. Twelve amps are considered a reasonable amount of energy to dedicate to your dishes; you won’t rack up a hefty bill. 

Bosch is renowned for being quiet. Aside from the Ascenta Series, every other product from this brand falls under 45dB. This means it emits a barely audible sound. 

There are also many features that new and long-term dishwasher owners will enjoy and navigate easily. 

However, you may be asking about the electricity it consumes. Or you may be curious about the most appropriate electrical circuit for it. 

An hour of using your dishwasher consumes 1,800 watts of electricity. You will pay $0.162 for each hour.

But even better, some hours of the day are more strategic for doing the dishes. 1 pm to 7 pm on weekdays have the highest demand for electricity, which makes it more expensive. 

It’s best to do your dishes between 10 am to 1 pm and 7 pm to 9 pm on weekdays. You can get up to 25 percent off. 

In a nutshell, a Bosch dishwasher helps you save money and cut back your energy consumption. You will also waste less water because a machine has been proven better at managing this resource when doing the dishes. 

Bosch also has additional features like a water softener, an EasyGlide system, the option for extra drying, and the ability to detect leaks so that you can deal with them without further delay. 

But even with these advances, Bosch does not exceed a dishwasher’s typical 10 to 15 amps. 

How Many Amps Does a Whirlpool Dishwasher Use? 

Like the average dishwasher, you only need 10 to 12 amps for a Whirlpool dishwasher. To be safer, dedicate 15 to 20 amps to using your Whirlpool dishwasher. A dedicated 20-amp circuit is the safest option for this device, so go with that. 

A Whirlpool dishwasher is one of the cheapest options on the market. It is also relatively noiseless, so you can go ahead with your open-plan kitchen. It is also easy to operate for a first-timer. 

There are many additional features that you will like, such as the fingerprint-resistant door. A Whirlpool dishwasher uses many pressure spray nozzles to ensure that your dishes gleam and are free of bacteria. 

Whirlpool dishwashers are available in different specifications. You get to decide what additional features you pay for. 

However, as it is, these extra bells and whistles consume additional energy. So, the best way to determine how many amps a dishwasher needs is to check the specifications plate on the body. It will be indicated that your new appliance will consume a certain amount of current, and you should buy a direct circuit with additional amps. 

How Many Amps Does a KitchenAid Dishwasher Use? 

A KitchenAid Dishwasher uses 15 amps of electrical current. However, additional features like heating, extra dry, smart features, and different applications will require more energy consumption. However, the manufacturer will inform you about the specific number of amps the dishwasher consumes – look at the back of the steel body. 

KitchenAid has been providing top-notch and budget-worthy kitchen appliances for a long time. If you subscribe to this brand, you likely know that the dishwashers are built-in, which is convenient if you are low on kitchen space, and that it does the job like a pro. 

How many amps does it use? Most times, it depends on the applications you explore on the appliance. The manufacturer will indicate the number of amps per hour or cycle the device consumes. 

It is safer to check because these models offer different specifications. As such, they don’t consume the same amount of electrical energy. But even then, you can reduce your dishwasher consumption by being mindful of how you use the features. 


How Many Amps Does a Maytag Dishwasher Use? 

A Maytag dishwasher uses 15 amps. It is higher than the average dishwasher because of additional features like pre-rinsing and pre-soaking and an improved dry cycle, among other features. Don’t go below 20 amps dedicated circuit for this appliance. 

We can easily see why you would favor a Maytag dishwasher. It has many excellent features that ensure doing the dishes is a stress-free chore. Whether you want quick action or an effective and deep clean, you can get it done in an hour to four. 

It has a 47dB noise rating, three-layered racks, and even an option to steam-sanitize your dishes. However, these advanced settings mean you will also pay more for electricity. If you want to use the hot water feature, the heater will work from the inside, consuming more energy. 

These are things you need to consider if you want to control your energy consumption. Of course, some appliances cannot be put aside entirely, but it is good to know that you can reduce the energy your dishwasher consumes. 

How Many Amps Does an LG Dishwasher Use? 

An LG dishwasher uses 15 amps of electricity. The various models you can choose are high-powered and effectively clean and disinfect your cookware and kitchenware. Many of them have smart features now and have incredibly low noise ratings. 

You may be choosing LG because of the advanced dishwashing features it offers. Whether you want it to stand alone or built-in, LG will satisfy that need. 

It also has nice drying features in almost every model. Additionally, homeowners are grateful because of its low or non-existent noise level. This makes this brand the perfect choice for an open kitchen. 

LG wants to give you the best, which may require you to sacrifice a few additional electrical current units. 

But again, there is an energy-saving feature in some of the models on the market. You can also reduce your energy consumption by using less of the bells and whistles. Alternatively, you may consider alternating the way you use them. 

Did you know that you can control the temperature setting for some LG dishwasher models? Another fantastic thing is the dual-zone tech; it allows you to wash different items in the same load. These energy-saving features help you stay on top of your consumption even with high-tech appliances like this.

How Many Amps Does a Kenmore Dishwasher Use? 

A Kenmore dishwasher uses 8.2 amps. This is a low number compared to the average dishwasher, which is a good thing because less energy will be consumed when you do the dishes. 

Kenmore is a popular American kitchenware brand. It is durable, energy-saving, and easy to use. Connect this device to a 15-amp direct circuit, and you will stay on top of electrical surges or overloads that may damage the appliance. 

How Many Amps Does a Frigidaire Dishwasher Use? 

According to this guide, the Frigidaire dishwasher uses 12.5 amps of electrical current. You should use a 20-amp circuit with it, especially if you are plugging something else alongside. 

A Frigidaire dishwasher is relatively expensive, so you want to use an appropriate direct circuit for it. Even better, you may preserve the lifespan of your investment by preventing short circuits. 

Can a Dishwasher and Refrigerator be on the Same Circuit? 

Yes, you can run a dishwasher and refrigerator on the same circuit, although it is preferable not to. Let them have their dedicated circuit. A refrigerator should have 20-amps, and a dishwasher should have 15 amps. 

Can You Plug a Dishwasher Into a Regular Outlet? 

Yes, you can plug your dishwasher into a regular outlet. However, it is better for your appliance if you use a special outlet, as it prevents short circuits and other electrical damage. 

It is okay to plug your dishwasher into a regular outlet, even though it is not advisable. 

Does a Dishwasher Use a Lot of Electricity? 

No, compared to other household appliances like the clothes dryer, refrigerator, and laundry machine, a dishwasher does not use a lot of electricity. It is higher than what the laptop, radio, and phone charger consume, but the energy it takes is still fair. 

You can expect your dishwasher to consume between 1200 to 2400 watts of electricity. Watts refers to the gadget’s electrical power, while amps refer to the electrical currents. 

To understand whether your dishwasher uses a lot of electricity, you must know that the energy you consume is measured in electric power. 

Electrical power is measured in watts, the amount of energy a device requires to run a single cycle, in the case of a dishwasher. Dishwashers consume between 1200 to 2400 watts of electrical power per hour. 

The average dishwasher will require 1800 watts, which is measured as 1800kWhr. Depending on factors like the size of your household and the number of guests you entertain, one cycle may not be enough daily. 

Some dishwashers allow you to load up many dishes. For instance, the Bosch dishwasher has three height levels which you can arrange into nine rack positions. This will enable you to wash more dishes in a single cycle, which saves electricity. 

Utility companies charge different rates globally. However, in the United States, you will pay $0.16 for each unit of electricity consumed. Businesses pay less because they consume more energy. 

Now, you can reduce your all-round energy consumption. To prevent the utility bills from racking up excessively, you can ensure that you never do the dishes halfway. Wait until you can fully load the dishwasher before hitting the start button. 

The water temperature can also be lower; it does not have to blast full-on before your dishes get squeaky clean. The best way to conserve energy in your home with this device is to use a lower temperature – less heating is required, saving energy. 

Don’t worry about the bacteria on the dishes; dishwashing soap contains biocides that will eliminate harmful microorganisms. 

Air drying is always better than heat drying. Heating the dishwasher requires more energy consumption than air drying it. 

Finally, when the family doesn’t use many dishes, you can handwash the ones used. Do this, especially if your dirty dishes will not give the dishwasher a full load. 


Knowing how many amps your dishwasher consumes will help you better manage your energy consumption. This is good not only for your pockets but also for the environment. 

This blog post has gone over the number of amps the average dishwasher uses. We have also discussed the energy consumption of seven popular dishwasher brands in the United States. If you haven’t bought yours yet, one of those mentioned above will satisfy your financial and household needs. 

It will also go easy on your electricity bills.
