When it comes to looking for a new dishwasher for your home it can become confusing when having to deal with all these different metrics. From dishwasher energy rating to eco wash 5000 it can all be a bit overwhelming!

Fortunately, this guide will take you through everything you need to know about the EU energy rating system, explaining the ins and outs of everything from the energy labels you find on the dishwashers within the showroom to how to save money on your energy bills and ensure your dishwasher is more energy efficient. 

 

Dishwasher Energy Rating Explained

When it comes to the energy ratings of a dishwasher it can seem confusing with all these different letters being thrown about however it is relatively simple once you understand the metrics being used. Contrary to many other appliances, the energy ratings for a dishwasher are not based on the energy consumption of the dishwasher. Instead, the energy rating is based on the energy efficiency in relation to the dishwasher capacity. The dishwasher capacity is determined by how many place settings can fit inside the dishwasher in one cycle. This means that on average the larger the dishwasher is and the more place settings you can fit inside of it the greater the energy consumption will be and therefore will be reflected in the energy rating score.

 

Dishwasher EU Energy Label Explained

 

When visiting a showroom to look for a new dishwasher you may find large energy efficiency labels hanging off the side of the dishwashers, with large letters ranging from A to G on them. These energy labels often contain a pyramid structure from green to red determining how energy efficient that dishwasher is rated on the energy label.

The energy ratings for dishwashers are measured using the EU energy rating system from letters A-G and measure the energy efficiency of the dishwasher but also the cleaning performance and drying performance of the dishwasher as well. A dishwasher that is labelled with an energy rating of A is deemed to be the most energy-efficient dishwasher and will save you the most money on your energy bills. A dishwasher that is rated with an energy rating of G will cost you the most money on your electricity bills as it consumes far more energy than a dishwasher with an energy rating of A would do.

How Much Does An A-Rated Dishwasher Cost To Run?

There are many different factors that determine the annual running costs of a dishwasher but as mentioned previously the most important factor is the size of the dishwasher and the number of places settings that the dishwasher can hold. Although a dishwasher may be A-rated the size of the dishwasher can determine how much it costs on your electricity bill. 

For example, an A-rated dishwasher that can fit 4 place settings within it (31kg dishwasher) will cost you an average £36.20 per year on your energy costs. An A-rated dishwasher that can ft 7 place settings within it (42kg dishwasher)  will cost you £50 per year on your energy bills. An A-rated dishwasher that can fit 9 place settings within it (50kg dishwasher) will cost you £58.70 on your electricity bills per year and a 14-place setting dishwasher (68kg dishwasher) will cost you £80 per year. 

These figures are based on the average person's use of a dishwasher and show how important it can be to understand the energy ratings and the factors on why one dishwasher that is rated as an A-rated dishwasher can be different to another!

How to Ensure Your Dishwasher is More Energy Efficient

With the cost of living rising and more people looking to save money on their energy bills, there are also some useful tips and tricks you can use to reduce those electricity bills and make sure each cycle of your dishwasher is as energy efficient as possible!

 

Run a Full Load

As simple as it sounds ensuring that your dishwasher is fully loaded every time you use it means that you will be maximising that single cycle instead of doing one cycle after breakfast, one cycle after lunch and one cycle after dinner. Instead, fully load the dishwasher at the end of the day after dinner and include every dirty dish, fork and bowl and wash them all together in one cycle. Each dishwasher cycle uses the same amount of water, electricity and energy so it is common sense that running one cycle over three a day will save you money on your bills!

 

Choose the Correct Programme

Most new dishwashers come alongside some crazy tech and this goes unnoticed by most owners who just slap on the same cleaning feature each time. However, features such as auto programmes include technology that can detect how dirty your dishes are and set the cycle optimal for that set of dishes so the correct temperature and amount of water is used. Using this feature can save you money on your energy bills as less energy is being wasted. 

Furthermore, if your dishwasher does not have an auto programme, it will most likely have an eco-wash programme that will reduce energy consumption and water use by 30%. Although this cycle will take longer it will reduce your energy bills significantly and cost you far less in the total lifespan of your dishwasher.

 

Scrape Your Dishes

 

There is no need to rinse your dishes in this day and age before putting them into the dishwasher because most modern dishwashers have the power to clean away tough stains. Instead, it is recommended to just scrape off the leftover food and place it into the dishwasher ready to be cleaned. This will save you time and money by not using warm water and soap to quickly rinse the plate!
