How Many Amps Does a Dishwasher Use?

How Many Amps Does a Dishwasher Use?

You will require 10 amps of current to run the average dishwasher. To prevent electrical overloading, it is essential to ensure that you’ve connected the dishwasher to a separate circuit with either 15 or 20 amps. The number of amps required to power a dishwasher will change depending on the model and brand.

Dishwasher 15 or 20 Amp?

A separate 120/125-volt, 15-amp circuit is necessary when setting up a dishwasher. A 14/2 NM cable supplies power to this 15-amp circuit. You can also use a 20-amp circuit with a 12/2 NM wire to power the dishwasher.

How Many Watts Does a Dishwasher Use

Most dishwashers use around 1800 watts every cycle. However, the average range is anywhere between 1200 and 2400 watts.

A dishwasher mainly needs energy for the pump and control electronics. That’s because, instead of the dishwasher heating the water on its own, water gets heated when you connect the dishwasher to the hot water line.

Samsung Dishwasher Amperage

The standard operating current for a Samsung dishwasher is approximately ten amps.

Dishwashers manufactured by Samsung are energy efficient. They often consume less power than dishwashers manufactured by various brands and models.

If you look harder, you can find more energy-efficient models. But most dishwasher models require approximately 10 amps of current. However,  some models can go as high as 20 amps.

Bosch Dishwasher Amperage
amp 2 1

Bosch dishwashers come in a few unique models. However, the 800, 500, and 300 are the most popular ones, requiring 15 amps to operate.

The amount of amperage required to run a Bosch dishwasher depends on several factors. These include:

  • The model
  • The appliance’s size
  • Optional features offered by the dishwasher model

Most home appliances will function at around ten amps and have a constant power consumption profile.

There are more energy-intensive cycles than others. For example, a sanitizing wash will require a higher temperature than a regular wash, which will take longer to complete.

Whirpool Dishwasher Amperage

Like other dishwashers, a Whirlpool dishwasher only needs 10 to 12 amps. However, you need 15–20 amps to use your Whirlpool dishwasher safely. It is safest to use a separate 20-amp circuit when using this model.

How Many Amps Does a Garbage Disposal Use?

An average garbage disposal uses significantly less power than the average dishwasher. However, you must take great care during installation because of their power consumption. Besides this, they come in a wide range of varying intensities, some of which need more power to function than others. Here’s a summary.

No. Garbage Disposal Horsepower Amperage
1. ⅓ Horsepower 4 amps
2. ½ Horsepower 9.8 amps
3. ¾ Horsepower 13.8 amps
4. 1 Horsepower 16 amps

Garbage Disposal With 1/3 Horsepower

1/3 horsepower garbage disposals use the least power. Also, their support system is the weakest. These disposals work well for things like cereal, peels from fruits and vegetables, and bread scraps.

Garbage Disposal with 1/2 Horsepower

Half-horsepower garbage disposals can grind up whole veggies and seeds with ease. Their power consumption is 9.8 amps. That is significantly higher than that of a standard 1/3 horsepower garbage disposal. These are ideal for households without many leftovers, such as couples or single people.

Dishwashers: Plug-in vs. Hardwired

Whether you want your dishwasher to be plugged in or hardwired into the home’s power circuit, it’s your call—Unless it’s required by law to have a hardwired dishwasher. But here are factors you need to consider:

Energy Usage

Energy usage is the same for both methods. A dishwasher that uses ten amps when running and 12 amps during a surge when you plug it will use the same amount of power when hardwired.

Convenience

Dishwashers plugged-in and hardwired differ primarily in terms of convenience and appearance. Hardwired washers save their owners time and trouble by eliminating the need to adjust power cords constantly. Also, when an appliance is hardwired, the power cords are concealed.

Plug-in dishwashers are easy to disassemble and inspect because you only need to disconnect the appliance. Stopping the electricity supply to a hardwired dishwasher requires switching off the appliance’s circuit breaker.

Security

Hardwiring the dishwasher could be a good alternative for added security. Hardwired dishwashers feature less exposed connections, making them less likely to come into contact with water. However, that depends on whether the washer was fitted correctly. And that any visible cables were encased in a flexible casing or protector.
