Are you ever curious why your dishwasher requires specific amperage or why you can't just plug it into any outlet? One solution comes in comprehending the significance of the power consumption of the dishwasher.

This blog post will uncover some mysteries behind dishwasher amperage and how it affects your appliance's operation. We will answer why a specific amp is necessary and what happens if you don't abide. We'll also discuss different amperage types in every brand today.

What is an amperage (amp)?

An amp, short for ampere, is a unit of electrical current. It is a measurement of how much electric charge flows through a conductor. The greater the number of amps, the more electric charge flows through the conductor. An electrical current passing across a circuit is frequently described as an amp. For example, a standard household circuit might have a draft of 15 amps. And this indicates that 15 units of electric charge travel through a channel per second.

There are two main types of amperage, namely:

  • Alternating current (AC) is the type of electrical current used in most homes and buildings. It is characterized by an oscillating flow of electric charge that periodically changes direction—AC power most household appliances, including dishwashers, washing machines, and refrigerators.
  • Direct current (DC) is a type of electrical current that flows in a single direction. It is commonly used in batteries and electronic devices such as computers, smartphones, and televisions.

In addition to these two main amperage types, there are several subtypes of AC and DC. For example, single-phase AC is used in most household electrical systems, while three-phase AC is used in more extensive commercial and industrial settings. Several types of DC also include pulsating DC, rectified DC, and smoothed DC.

Overall, AC and DC are the two main types of amperage, used for different purposes depending on the specific electrical system and the powered appliances or devices. So, choosing a suitable kitchen unit that is compatible with your home's electrical system and meets your needs in capacity and size is essential. Researching and understanding how much electricity a dishwasher uses - of all types and models - can help ensure that you make an informed and effective purchase.

How many amps does a dishwasher use?

When designing or renovating a kitchen, you may wonder, "how many amps does a dishwasher pull or require." Dishwashers are a convenient and effective way to clean your dishes, but they need a certain amount of electricity.

First, it's essential to understand that the amount of amps an appliance draws is not the same as the power it consumes. The power of a device or appliance is measured in watts, a combination of the current (amps) and the voltage (volts) at which the machine operates. For example, a unit that operates at 120 volts and draws ten amps would have a power rating of 1200 watts (120 volts x 10 amps = 1200 watts).

Now, let's get back to how much power does a dishwasher draw. The answer will depend on any specific unit's model and make and its motor type. We've included some typical current usage by appliance brands below:

  • Bosch - 12 amps
  • KitchenAid - 15 amps
  • Kenmore - 8.2 amps
  • GE - 6.6 amps
  • LG - 15 amps
  • Black & Decker - 12 amps
  • Maytag - 15 amps
  • Whirlpool - 10-12 amps
  • Frigidaire - 12.5 amps

However, it's still important to consider an amp that draws off your appliance when designing or renovating your kitchen. You'll need to ensure that your home's electrical system can handle your appliance's load and any other devices you may have. Most homes have a main breaker panel with a maximum load capacity of 100-200 currents. And this means that the total electricity draw of all the appliances and devices in your home should not exceed the power of the main breaker panel.

So consult a professional if you're unsure about how much electricity your dishwasher uses or the capacity of your home's electrical system. They can help you determine the best way to safely install and operate your kitchen unit.

What is the importance of dishwasher amperage?

The amp of a dishwasher, also known as its electrical current, is an essential factor to consider when purchasing and using this appliance. The electrical current ratings of a device will determine how much electrical power it consumes and how much load it places on your home's electrical system.

A dishwasher with a higher electrical current rating will require more electrical power and may significantly load your home's electrical system. And this can be a problem if your home's electrical system is incapable of handling additional loads, as it can cause issues such as blown fuses or tripped circuit breakers. On the other hand, a unit with a lower amp rating will consume less electrical power and place a smaller load on your home's electrical system.

In addition to considering electrical current ratings, it's also essential to consider your appliance's size and how it will fit in your kitchen. A unit with a larger capacity will typically have a higher amp rating, as it will require more electrical power to operate. Opt for a smaller model with a lower electrical current rating if you have a small kitchen or limited space.

What happens if you don't abide by dishwasher amperage requirements?

When you don't abide by the dishwasher power rating requirements for your home, it can cause problems with your electrical system and potentially damage your kitchen unit, such as the following:

  • If the dishwasher current consumption is drawing too much power, it can cause the circuit breaker to trip or blow a fuse, disrupting the flow of electricity to the appliance.
  • It can also create a safety hazard, as damaged electrical wiring can cause fires.
  • If the unit is not drawing enough power, it may not function correctly and not clean your dishes effectively.

Choosing the right one that is compatible with your home's electrical system and meets the necessary electrical current requirements to ensure safe and effective operation is essential.

What are the factors that influence dishwasher amperage?

Several factors can influence the electrical current of a dishwasher, including:

  1. The type of motor: Units with engines that operate at higher voltages will typically have a lower amp rating, as they will require less electrical power to operate. For example, a unit with a 240-volt motor may have an electrical current rating of 3-6 amps, while one with a 120-volt engine may have an amperage rating of 6-12 amps.
  2. The size and capacity of the dishwasher: Larger units with a higher degree may have a higher amperage rating, as they will require more electrical power to operate. If you have a small household or don't do a lot of dishes, you can get away with a smaller one with a lower amperage rating.
  3. The specific cycle being run: The amperage of a dishwasher may vary depending on the particular process it is running. For example, it may draw more amps during the wash cycle than during the drying cycle. Some dishwashers also have multiple wash cycles with different amperage ratings, so you must consider which process you'll use most often.
  4. The dishwasher's age: Due to outdated technology and less energy-efficient motors, older dishwashers may have a higher amperage rating. If you're considering a used or vintage dishwasher, it's essential to check the amperage rating to ensure that it's compatible with your home's electrical system.
  5. The overall efficiency of the dishwasher: Dishwashers that are designed to be more energy-efficient will typically have a lower amperage rating, as they will require less electrical power to operate. Energy-efficient dishwashers can help save money on your monthly energy bills.

It's essential to consider these factors when choosing a dishwasher, as they can affect the appliance's power consumption and the load it places on your home's electrical system.


Knowing "how much power does a dishwasher use" is essential when purchasing and using this appliance. Choosing a model compatible with your home's electrical system and meets your needs in terms of capacity and size is vital. By taking the time to research and understand how many amps does a dishwasher take, you can ensure that you make an informed and effective purchase.
