The electricity usage of a dishwasher may vary considerable depending on the efficiency and age of the appliance.
If you already 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.
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.
PRO TIP: Generally if the electricity consumption is low, the power consumption details are easy to find. And the opposite, is the electricity usage is higher that other similar dishwashers, the power consumption details may be a bit hidden.
For the dishwasher displayed on the picture above, the specifications state that it consumes 237 Kilowatts hour (kWh) per year.
Because we are paying to our electricity provider 0,217 euro per every Kilowatt hour that we consume, we can easily estimate that this dishwasher would cost us around 51 euro per year in electricity costs.
Once you know your diswasher’s model, it is quite simple to search on the internet how many kWh of electricity the dishwasher is using. Then, you can use the calculator below to find out your dishwasher’s electricity cost.
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.
Once we know the yearly power consumption, the calculator below can be used to estimate 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.
For example, if your dishwasher has:
> A yearly power usage of 237 kWh
> You are paying 0,2 euro (or dollars, or pounds, or …) per every kWh you consume
You will be paying around 47 euro (or dollars, or pounds, or…) per year in electricity costs.
A few other examples from our ‘Electricity usage calculators‘ page that may be of your interest:
Still, if you want to know the exact electricity usage of your fridge, your best option is to use a plug in power meter to measure the electricity consumption.
Clicking on the image below it will redirect you to the Amazon page where you can have a look to the specifications of the power meter we use for our measurements.
All of our house appliances and devices like the washing machine, the dishwasher, the TV or the printer are plugged to a wall socket.
So, with a power consumption meter we can determine how much electricity our appliances or devices are using and, more importantly, we can measure the electricity usage over a period of time.
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.
As an example, in our case, we were using mostly all the time the Auto cycle for washing our dishes.
Once we measured the power consumption using a plug in power meter and we found out 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.

If you think that your diswaher it is using too much electricity, here there are three simple ways to reduce the power consumption of a dishwasher:
1.- Use the energy saving mode
If your dishwasher has an ECO or energy saving mode, use it. It will most proably save you quite a bit of electricity, and water, and decrease your bills.
2.- Fill it up… and do it correctly
Maybe this tip it is an obvious one, but it is worth to mention it. Fill up your dishwasher by neatly staking the dishes, cups, glasses, cutlery in their designated trays.
3.- Buy an energy efficient model
If you have an old dishwasher, it may be worth to start considering to buy a newer and more efficient model. But be careful, do not spend too much money on a mega efficient dishwasher because it may be not worth. In case of doubt, have a look to this post where we explain how to calculate the payback period.
Not everybody it is familiar with terms like Watts, Kilowatts or Kilowatt hours so if you would learn more about them, have a look to this video that we have prepared for you.
Or you can have a look to this electricity measurement units calculators to get a better understanding of:
> What is a Watt (W) and how to transfor Watts into Kilowatts
> What is a Kilowatt (kW) and how to transform Kilowatts into Kilowatts hour
> What is a Kilowatt hour (kWh) and how to transfor Kilowatts hours to other units
> What is Power (P), Voltage (V) and Current (I)
Energy conservation can be defined as the decision and the act of using less energy
Energy conservation both benefit you and the environment
The act of saving and conserving electricity does benefit you because you will be paying less on your energy bills.
And it also does benefit the environment because conserving electricity prevents any unnecessary waste of natural resources.
Now, at individual level it may not look worth to try to save a few watts here or there.
Still, every little counts and if hundreds or thousands of us do save a little every time, it will make an important contribution towards conserving our natural resources.
For example, if 9000 households would manage to save as little as 10 Watts per hour (0,01 kWh) worth of electricity per day, that would add to 32850 Kilowatt hour (kWh) per year.
That is a considerable amount of electricity, but let’s add additional perspectives for clarity:
> Assuming an average cost of 0,18 euro (or dollars, or pounds, or any other currency) we would collectively be saving nearly 6000 euro per year.
> To produce 32850 kWh of electricity it is necessary to use around 17 metric tons of coal or 56 barrels of residual fuel oil.
In any case it is clear that small energy savings do really count when looking into the bigger picture.
