How much water and energy does a dishwasher use?

Are you looking for a new dishwasher, but aren't you sure what you pay for water and energy consumption? In this article, we'll explain how much the consumption of a dishwasher is and how much you'll have to pay on annual energy costs on average. A dishwasher with an A-10% energy label is the most energy-efficient.

Energy consumption dishwasher

On the energy label of a dishwasher, you can see its exact consumption per 100 cycles. The energy costs in the table on this page are based on an energy price of € 0.30 per kWh and 280 cycles per year, which is over 5 cycles per week. These numbers were calculated by the European Union. An A-10% energy label dishwasher is more expensive to purchase, but you can save about € 330 on your energy bill after 10 years compared to the E energy label dishwashers.

The water consumption is also listed on the energy label. The number under the faucet indicates the number of liters per cycle during an Eco cycle. When you multiply this number by € 0.0014, you'll get the average water price. Multiply this with 280 cycles and you'll have the average price per year. For example, the energy label indicates a water consumption of 7.7L per cycle. You pay about € 0.11 for water consumption per cycle, and a total of € 3.02 annually.

Formula energy costs

Do you want to calculate the average annual energy costs in euros? First, you'll have to know the annual energy consumption. The energy label indicates the consumption per 100 cycles. In order to get the annual energy consumption, you multiply the number on the energy label by 2.8. The EU uses an estimate of 280 cycles per year. Now the sum goes € 0.30 x average energy consumption in kWh per year. If the annual energy costs are low, you save more money and you're doing the environment a favor.
