How Many Watts Does A Dishwasher Use

How many watts does a dishwasher use? An average dishwasher uses about 1800 watts. Dishwashers are termed as big energy consumers because they use heat, water, and electricity to run. Dishwashers use heat, water, and electricity to run, so they are one of the most energy-intensive home appliances. However, they are not the biggest electricity users compared to other large appliances; we can term them as medium consumers.

If you want to save on electricity costs while still using the dishwashers, the best way is to switch to alternative power sources like solar generators. The Jackery solar generator range includes various sizes that support multiple appliances. The large 3000 pro and 2000 pro Jackery solar generators have enough capacity to power 99% of your home appliances.

Dishwasher Wattage Key Takeaways

• How many watts does a dishwasher use? An average dishwater consumes about 1800 watts.

• You can calculate a dishwasher's power consumption by multiplying the Dishwasher's wattage by the hours used. For example, if a dishwasher has an 1800 watts rating and it is used for one hour a day, the daily consumption is

1800 x 1 = 1800 watt-hours (Wh) of electricity.

Or 1.8 kWh of electricity

• Alternatively, if a cycle uses about 1.17 kWh of power per cycle, if 215 such cycles are run in a year, then the average annual consumption is 252.81 kWh per year or 20.98 kWh per month.

How Many Watts Does A Dishwasher Use?

Dishwashers consume between 1200-2400 watts of power, while the average consumption is about 1800 watts. This power is used for the control electronics and the pump. Additionally, hot water is coming from the line. Investing in an energy-efficient dishwasher also helps to make its use highly economical.

Knowing how dishwashers use energy would help you make an informed decision about dishwasher use and its power consumption.

Dishwashers use electric power in multiple operations.

1. Heating

Dishwashers heat the water to clean the dishes. This element has the biggest power consumption, especially if running a long cycle or setting high temperatures. If you have hot water in the line, you can save on power in the Dishwasher.

2. Motor

Dishwashers use a motor to circulate water and detergent while cleaning the dishes. It is also a major contributor to how many watts a dishwasher uses.

3. Displays

The control panels and displays make using the Dishwasher very easy for you. The good news is that these panels and displays use minimal power.

What Factors Affect The Dishwasher Wattage?

How many watts a dishwasher uses depends on factors like the size of the Dishwasher, efficiency, temperature settings, and cycle duration.

1. Larger dishwashers need more water and power to operate; hence, they use more wattage than the smaller ones. However, if you have to wash many dishes, you must see if you can accommodate all dishes in small dishwashers, or you will need 2 cycles.
2. Modern energy-efficiency dishwashers are more economical than old, more power-hungry appliances.
3. If your Dishwasher gets hot water from the line, it will use less power than when heating water internally.
4. Choose smaller cycles as they are more economical.

How Much Does It Cost to Run A Dishwasher?

As we already discussed, the average power consumption of dishwashers is 1800 watts. If you run the Dishwasher for an hour, the power consumption is approximately 1.8 kilowatt-hours (kWh) of electricity. The US average cost per kWh is around $0.16.

Power consumption daily = 1.8 x 0.16 = $0.288

Power consumption weekly(7days of use) = $2.016

Power consumption monthly = $8.64

The following table summarizes how many watts a dishwasher uses and the average cost depending on size.

How To Save Money While Using Dishwasher

While discussing how many watts a dishwasher uses, we can also see how we can save this power cost. Let us list a few ways.

1. You may opt for handwashing your dishes as it takes less electric power. This is especially relevant when you have a few dishes.
2. Wait till you have a full dishwasher load. Hence, you run it only a few times weekly.
3. Run your Dishwasher in off-peak hours when the power tariff is lowest. Generally, the rate is lower at night. Generally, running your Dishwasher later at night is cheaper, before you're getting ready to go to bed, and most people have turned off most of their appliances.
4. I invested in a more power-efficient dishwasher.
5. Run your Dishwasher on high-capacity solar generators like Jackery Solar Generators 3000 pro or 2000 plus. Solar energy is not only cheaper but also more environmentally friendly.

How To Calculate The Working Hours Of A Solar Generator

When you know how many watts a dishwasher uses and you want to transfer it to a solar power generator, the next question is, how long can a solar generator run my Dishwasher?

The working hours of a solar generator for a particular appliance can be calculated using this formula.

Working time = Capacity Wh * 0.85 / wattage of your Dishwasher

For example, we take the general example of an 1800W dishwasher.

The Jackery solar generator 3000 Pro Working time will be 3024Wh * 0.85 / 2000w = 1.42 hrs.

We always incorporate an estimated 15% loss of capacity during operation and transmission. Therefore, we multiply the given efficiency by 0.85. This helps us to state more realistic data rather than idealistic.

Dishwasher Wattage FAQs

1. Do dishwashers use a lot of electricity?

An average dishwasher consumes between 1.2kWh and 1.5kWh per load. The most efficient dishwashers have an energy rating of A or B. Dishwashers are medium-level energy consumers.

2. How do I know what wattage my Dishwasher is?

You can generally find the wattage of your Dishwasher stated in the user manual or on the energy rating label on the device itself.

3. Is it cheaper to run a dishwasher or wash by hand?

It depends on a few factors like the number of dishes, how often you have to run it, and how energy and water-efficient your Dishwasher is. Most modern dishwashers use between 11 and 13 liters of water per cycle. If you wash a full dishwasher load by hand, you will use up to nine times that amount. But if you usually run half a load or fewer dishes in the Dishwasher, then hand washing is better.

However, dishwashers come out on top for full loads in the Dishwasher versus handwashing cost.

4. Does the Dishwasher increase the electric bill?

Yes, they do. An average dishwasher uses 1800 watts of power, and a fraction of this power is still needed when the Dishwasher is not running.

5. Is a dishwasher 120v or 240v?

Most dishwashers in the United States work on a standard 110-120 volt outlet. However, some European models need a 220-240 volt outlet.

Final Thoughts

How many watts a hwasher uses depends on its size, power rating, and features. Small portable dishwashers can run on 1000 to 1500 watts; however, average dishwashers use about 1800 watts of energy. At the same time, the most powerful models can consume 2,500 watts or more. Using solar power generators, running your Dishwasher a few times a week only, and air drying your dishes can help you save on dishwashing costs.
