If you’ve ever wondered how much water your dishwasher uses in litres, you’re not alone. As someone who likes to optimize every aspect of my life, I was curious to see if there was a way to reduce the amount of water my dishwasher uses without sacrificing performance. I scoured the internet, talked to experts, and even conducted my own experiments to get to the bottom of this water mystery.
The amount of water your dishwasher uses in litres can vary depending on a few factors, such as the make and model of your dishwasher, the size of your load, and the chosen cycle. Some older models can use up to 40 litres per cycle, while newer, more energy-efficient models may only use 12-15 litres per cycle. However, just because a dishwasher uses less water doesn’t necessarily mean it’s any less effective at cleaning your dishes. In fact, some of the best-performing dishwashers on the market today use as little as 6.5 litres of water per cycle. So, the real question is, how can you make sure you’re getting the most out of your dishwasher while also reducing your water waste?
Water Efficiency of Dishwashers
When it comes to purchasing a dishwasher, one important factor to consider is its water efficiency. Fortunately, most modern dishwashers are designed to conserve water and energy while still providing excellent cleaning performance.
- The average dishwasher uses about 6-16 litres of water for each cycle, depending on the make and model.
- Dishwashers with an Energy Star certification use no more than 10 litres per cycle, which is about half the amount used by older models.
- High-end dishwashers can use as little as 4 litres per cycle.
In order to determine the water efficiency of a dishwasher, you should look for its Water Factor (WF) rating. This rating indicates the number of litres of water used for each place setting, and the lower the WF rating, the more water-efficient the dishwasher is.
It’s important to note that while some people assume hand-washing dishes saves water, this is not necessarily the case. According to research, washing dishes by hand can use up to 27 litres of water, compared to the 6-16 litres used by a typical dishwasher cycle.
Additional Tips for Improving Water Efficiency
- Scrape excess food off dishes before loading them into the dishwasher, instead of pre-rinsing in the sink.
- Run full loads of dishes whenever possible, as this uses less water overall.
- Use the “eco” or “energy-saving” cycle if your dishwasher has one, as this will decrease water usage and energy consumption.

- Hand washing: This is the most obvious choice, but it’s one that many people avoid because they don’t want to spend the time or energy on it. However, hand washing can be a very effective way to clean your dishes, as long as you use the right soap and technique. Choose a detergent that’s gentle on your skin and the environment, and fill a sink with hot water. Use a scrub brush or sponge to clean your dishes, and rinse them thoroughly.
- Vinegar: If you have hard water and are tired of dealing with water spots on your dishes, try adding a cup of vinegar to your rinse cycle. This will help remove any minerals that are causing the spots, and will leave your dishes looking clean and shiny.
- Lemon juice: If you want to add a fresh scent to your dishes, try using lemon juice instead of vinegar. Add a quarter cup of lemon juice to your rinse cycle, and your dishes will come out smelling great.
If you’re looking for a more sustainable way to wash your dishes, there are a few options you may want to consider:
First, you can reuse your dishwater. Instead of draining the sink after you’re done washing, use the same water to rinse your dishes. This will save water and detergent, and can be a great way to conserve resources.
Second, you can use a dishwashing soap that’s specifically designed to be eco-friendly. Look for products that are made from natural ingredients, and that come in biodegradable packaging.
