Energy Efficiency Ratings for Dishwashers

Energy Efficiency Ratings for Dishwashers

A dishwasher’s energy efficiency depends on the amount of energy and water used. The kWh and price of water per litre are measured over 100 cycles. Like washing machines, dishwashers are tested on the most eco-friendly setting. It’s then filled with dishes to obtain the most accurate energy rating.

Like other appliances, the energy efficiency of dishwashers can differ depending on usage. There are a few ways you can improve the energy efficiency of your dishwasher:

  • Fill the appliance to capacity to run fewer cycles
  • Use energy-saving modes
  • Select a lower temperature setting

FAQs

Why has the energy label changed?

With 'A' being associated with a good rating by consumers, the addition of A+, A++ and A+++ ratings made the old system less transparent as products moved up the scale due to improvement in product efficiency. The revised A-G system has reset the scale, making it easier to understand, as well as incentivising manufacturers to product even more efficient products.

What has changed on the new label?

The scale is now between A-G, with no extensions to A+ classes anymore. The label will also feature the Union flag as opposed to the EU version post-Brexit. Some new icons have been added, and older ones adapted, to provide a more transparent insight into the products.

Which product categories are changing?

Lighting, Fridges/Freezers, Washing Machines, Washer-Dryers, Dishwashers and Wine Storage are now on the new rating system. Changes to further product categories will occur in 2026, this will include Tumble Dryers, Range Cookers and Hoods.

What do we mean by energy efficient?

If an appliance is deemed energy efficient, it operates effectively using less energy. An energy-efficient appliance saves you money and helps you live sustainably. The formula to calculate energy efficiency considers how much power an appliance uses and produces. This means we look for the product that uses the least energy to provide the right amount of power.

How do energy ratings affect your appliances?

As your appliances are fit for different purposes, their energy efficiency is assessed differently.
