How much power does dishwasher use?

Dishwashers come in different sizes and they are also used in many different modes. However, a regular dishwasher usually consumes (per-load) of 1-2 electric units (source: http://www.fsec.ucf.edu/en/publications/pdf/FSEC-CR-1772-08.pdf).

We also recently measure the dishwasher energy usage and found that the dishwasher machine consumed only 1 unit of electricity at the optimal and energy-efficient option available. We can say that after using one month it will consume 25-60 units of electricity.

How much electricity does a dishwasher consume?

Let assume that your dishwasher operates 1 hour a day, Average power consumption of the dishwasher between 1000 to 2400 watts. Let’s take an example and say your model uses 1600 watts and per unit price of electricity in your is  10 cents.

1600 watts X 1 hours = 1,600 watt-hours per day

How many kilowatts does a dishwasher use?

1,600 watt-hours per day / 1000 = 1.6 kWh per day

How much does it cost to run a dishwasher every day?

1.6 kWh per month x 0.10 per kWh = $ .16 per day

How much does it cost to run a dishwasher?

1.6 kWh per day X 30 days = 48 kWh per month
48 kWh per month x 0.10 per kWh = $ 4.8 per month

Some key tips for saving power in the use of the dishwasher

The following tips help us in saving additional electricity spent on the use of a dishwasher:

Tip-1:Use the dishwasher only in the low-temperature setting. The use of heating consumes more electricity. so it is necessary that you use the dishwasher on the ‘optimum’ temperature setting. For more information on this, you can read the information and recommendations given by the manufacturer in the product manual.

Tip-2:Make sure that the dishwasher is fully loaded at the time of use, but it should not be overloaded.

Tip-3:If there is ‘air-dried’ mode available in the dishwasher to dry the vessel, then we should use the same. To dry the vessel, we should avoid using the heating element. The use of heating elements consumes more energy.

Tip-4:Try to use a dishwasher in the most energy-efficient mode as described in the dishwasher-manual. Efficient use of energy-efficient dishwasher will save not only the energy but also save water and as we all know that both are valuable resources.

Be careful when using the dishwasher

  • Do not use aluminum utensils. Dishwashing detergents can also cause problems with food poisoning. This happens when some powder is left in the vessel and they go to the stomach through the diet.
  • There have been many cases where a person has a problem with food poisoning by the dishwasher.
  • Every household has a lot of things that you can’t wash in the dishwasher. If you have accidentally washed them in the dishwasher, it can be damage.

How does a dishwasher operate?

A dishwasher operates in the sequence of some automated steps, which means that it follows a certain process to operate, which is a combination of several methods, but this method is automatic and works only in a sequence.

A dishwasher is filled with water and heats the water at the desired temperature. Then the utensil is sprayed with hot water and detergent, the draining of the water and the process of re-filing it continuously.

Finally, the utensils are drying in the air or by giving heat or drying in the sun. As is known, generally there is considerable consumption of electricity in any heating operation, so additional power consumption is also done through the dishwasher to heat the water and dry the utensils through heat.
