If you are thinking of buying a new dishwasher you might be wondering what the wattage of the device is. Average dishwashers use between 1,000 and 1,500 watts of electricity. The running wattage however is lower, because it doesn’t run on full power all the time. For an average dishwasher you can expect it to be 80% (depending on the setting) of the wattage.
The power consumption of a dishwasher largely depends on how often you use it in a day. If you use an 1 kW dishwasher for one hour every day, you can expect it to consume around 1000 watt hours in an average day or 365 kWh per year..
It’s important to keep in mind that the exact power consumption varies depending on the model and size you choose. Age also plays a role when calculating the energy efficiency of electronic devices. Generally speaking, if you purchase a new dishwashing machine, you can expect it to use less watts than an older model.
Power Consumption Of A Dishwasher Summarized
| Average Power Usage | Time | kWh Used |
|---|---|---|
1000 Watts | 1 Hour | 1 |
1000 Watts | 1 Day | 1 |
1000 Watts | 1 Week | 7 |
1000 Watts | 1 Month | 28 |
1000 Watts | 1 Year | 365 |
(Energy consumption is calculated based on an average usage of a dishwasher.)
If you want to find out how much it costs to power your dishwashing machine, you need to multiply the kWh used in a specific time period by your electricity rate. In 2024 the average price of electricity for residential customers in the US is currently $0.16 per kWh. Running an average dishwasher for one year will therefore cost around $58.40. If you live in California, where electricity currently costs $0.26 per kWh it will cost you around 60 % more. In the State of Utah, which currently has the cheapest electricity in the USA at only $0.11 per kWh, you can expect to pay around 30 % less to power your dishwasher.
The power consumption of your dishwasher is important to consider, when trying to save energy or planning a solar system. If you want to verify the exact wattage of your device, we recommend looking out for the EnergyGuide label on the packaging.
Buying An Energy-Efficient Dishwasher
As you can see, the operating costs for a dishwasher can quickly sum up. If you are about to buy a new dishwasher, we recommend choosing an energy efficient model. Keep an eye out for the ENERGY STAR labels. Unlike the EnergyGuide label, the ENERGY STAR label only marks devices that have proven to be particularly energy-efficient.
Additionally, consider the following tips when purchasing your new dishwasher:
- Research Before You Buy: Before making a purchase, it’s wise to do some research. Look for customer reviews and ratings to understand the performance and reliability of different models.
- Compare Energy Consumption: Check the energy consumption details of various models. Sometimes, spending a bit more on a more energy-efficient model can save you money in the long run through reduced utility bills.
- Size Matters: Ensure that the size of the dishwasher fits your needs. Larger models often consume more energy, so buying a bigger size than necessary can be less efficient.
- Look for Advanced Features: Some modern dishwashers come with advanced features that help save energy. Features like programmable settings or eco-modes can make a significant difference in energy consumption.
- Calculate the Total Cost of Ownership: Remember to consider not just the purchase price, but also the long-term operating costs. An energy-efficient dishwasher may have a higher upfront cost but can lead to significant savings over its lifetime.
By choosing an energy-efficient dishwasher, you are not only saving money but also contributing to a more sustainable environment. Always balance your immediate needs with long-term efficiency and costs.
Power Your Dishwasher With A Solar System
Did you know that you can produce enough electricity to continuously power a dishwasher with less than 1 solar panel(s)? That’s because a standard 400 watt solar panel in the USA generates on average around 600 kWh of electricity per year. If you live in the northern parts of the country, you can expect a slightly lower output, while the output in the southern parts of the country, especially in Texas and Arizona, will be slightly higher.
Factoring all other devices you already have in your house, a solar system might save you tens of thousands of dollars over a period of 20 years. With these savings, the decision to go solar becomes not only environmentally responsible but also financially wise.
When considering the switch to solar, it’s important to get the best deal and the right setup for your needs. That’s where Quote For Solar comes in. By choosing Quote For Solar, you can easily request quotes from 3 local solar installers near you. Don’t miss out on the opportunity to power your dishwasher and other appliances in a cost-effective and sustainable way.
