- How much electricity does a dishwasher use? -

The electricity usage of a dishwasher may vary considerable depending on the efficiency and age of the appliance.

Newer and efficient models most probably are going to be more economic. Still, if you have a dishwasher at home or if you are considering to buy one, it is worth to spend a little time and find out the electricity usage and the electricity cost.

Dishwasher electricity usage

The electricity usage, or the power consumption, should be clearly displayed or easily at the appliance itself of easily accessible online.

Still this is not always the case. If the electricity consumption is low, the power consumption details are easy to find. And the opposite, is the electricity consumption is higher that other similar dishwashers, the power consumption details may be a bit hidden.

Electricity usage and cost calculator

We have chosen a random dishwasher and made a simple search for its ‘datasheet’. Out of the results, we have been able to find its power consumption both at Amazon and at the manufacturer’s website.

Dishwasher Datasheet

Once we know the yearly power consumption, the calculator below can be used to calculate the power and cost consumption of the dishwasher.

You just need to adjust the values in the PARAMETERS section to your requirements and the calculator will automatically display the RESULTS section.


Still, if you want to know the exact electricity usage of your dishwasher, your best option is to use a plug in power meter to measure the electricity consumption. 

This is because a very efficient usage of the dishwasher may decrease its power consumption and electricity cost. And the opposite, a very poor usage may increase its power consumption and electricity cost.

For more details, have a look to this post that we have created to show you how to use a plug in power meter to measure your appliances and devices power consumption.

Plug in power meter electricity consumption

As an example, we were using mostly all the time our dishwasher’s Auto cycle for washing our dishes. Once we measure the power consumption using a plug in power meter, we came to realize that the Eco cycle is much more economic.

Since then, we are using all the time the Eco cycle which is saving us quite a bit of money. The lesson, if you have a smart appliance, use it smartly.

Auto0,80-1,10 KWh0,20 - 0,28 euro
Auto + Vario Speed1 KWh0,28 euro
Eco0,60 KWh0,15 euro
