Dishwashers are labelled on an energy efficiency scale ranging from A+++ (most efficient) to D (least efficient). These ratings take into account:
- energy consumption
- programme time
- power consumption when the dishwasher is not switched on
- power consumption in standby mode
- standby mode duration
- capacity of the dishwasher
Besides providing energy efficiency insigths, the label also includes information about:
- water consumption
- noise emissions
The European Commission provides tools for generating energy labels for products on the EU market.
Ecodesign requirements apply to dishwashers sold in the EU. These requirements cover:
- energy efficiency
- cleaning and drying performances
Standby and off mode
A wide range of electric devices can have standby and off modes.
These are required to switch into a low power mode (such as standby) after a reasonable amount of time and they must not consume more than 0.5 Watts in standby or in off mode.
By switching to a more energy efficient dishwasher, you can save up to €300 over the average lifetime of the product.
With the implementation of the EU energy labelling and ecodesign requirements for efficient dishwashers, the member states of the EU will be able to save up to 2 TWh of electricity per year by 2020. This is more than double the annual energy consumption of households in Malta.
