Nobody would be critical of you if you assumed that a dishwasher uses a sizable amount of water for each load. After all, one of the largest appliances in your home is usually this one. You may have wondered how much water does a dishwasher use.
Depending on the brand and model of your appliance, many newer dishwashers are more efficient than you might realize. Undoubtedly, a contemporary dishwasher with an Energy Star rating will operate much more efficiently than a more traditional one.
Please read on for more detailed information.
How Much Water Does a Dishwasher Use?
It’s important to take into account all the contributing factors when calculating the overall environmental impact of cleaning your dishes, including the age of the appliance, the amount of water used, and the amount of energy consumed.
The average dishwasher uses six gallons of water per load, with energy usage estimated to be between 0.88 kWh and 1.58 kWh for an average wash cycle. This is taking into account the various options and features that various brands may offer. Dishwashers made after 2013 are required to use no more than five gallons of water per cycle due to standards that went into effect in 2013. Numerous dishwashers come equipped with an internal heater that can heat the water more effectively than your hot water tank, allowing you to save even more energy.
When taking into account the time it takes to run the water to reach the desired temperature and the time it needs to run during the rinsing phase, washing dishes by hand can use up to 27 gallons of water per load. These two habits, along with pre-rinsing dishes before putting them in the dishwasher, can result in a significant annual resource waste.
Cut Down Your Dishwasher Water Usage and Boost Energy Efficiency
We now understand that using the dishwasher is generally more environmentally friendly than washing by hand, but we’ll probably need to use both methods occasionally.
Whether you choose to hand wash or use a dishwasher, our eco-friendly dishwashing tips will help you conserve energy and water.
Choose Or Switch to a More Energy-efficient Model
The European Commission estimates that switching to a more energy efficient dishwasher can save you up to €300 (about £270) over the average lifetime of the machine.
This guide includes advice on selecting the best dishwasher later on, but the energy label is the most important thing to pay attention to. Dishwashers are rated according to their energy efficiency on a scale from A+++ (the most efficient) to D (the least efficient). If you can, try to get an A+ or higher.
Make Sure the Dishwasher’s Fully Loaded
Cutting just one dishwasher cycle a week by making sure it’s always full before it’s turned on can save £9 on your electricity bill, and save water to boot.
And while we’re speaking about loading the dishwasher, make sure it’s loaded correctly – otherwise, you’ll end up re-washing your dishes (and using more water).
Whatever You Do, Don’t Pre-rinse
Pre-rinsing dishes before they go in the dishwasher could be wasting more than 22,000 litres of water per year. Such a large amount of water.
If there is a baked-on crust or dried-up sauce on the dish, you might assume the dishwasher cannot handle it. But in actuality, any modern dishwasher worth its salt can do it.
To get the best results, use an efficient dishwasher tablet or detergent and make sure to scrape off any obvious food remnants. The machine will take care of the rest.

Use the Economy Or Energy-save Program
With this clever feature, the answer is in the name. Unsurprisingly, eco or energy-save settings use less energy and water than other options.
The programs use approximately three liters less water than the typical dishwasher cycle while washing dishes at a lower temperature, usually 50ºc. If your dishwasher doesn’t have an economy mode, check for a low water or quick wash cycle.
Don’t Be Drawn in by the Half-load Setting
You might believe that a half-load uses half as much water in the dishwasher. But that’s not the case, regrettably. Even though this type of program uses less water and energy than a typical cycle, the water savings are not equal to halving it.
Waiting until your dishwasher is completely full before choosing an economy or water-saving cycle is always more cost-effective.
Air Dry Your Dishes
Just open the door at the end of the washing cycle and let the dishes air dry rather than allowing your dishwasher to use electric heat or a fan to dry the dishes. According to research, reducing heated drying from your dishwasher’s routine reduces greenhouse gas emissions by 11%. Not bad.
Keep Your Dishwasher in Good Condition
It’s critical to maintain your dishwasher in top condition if you want it to run as efficiently as possible. Even though they may be tedious, reading the manuals and instructions that come with your machine will help you understand what routine maintenance is required.
Dishwasher Vs Hand Washing: Which is Better?
We all want to know this, let’s face it. Dishwashers are useful time savers, but do they conserve water and energy or do they use too much of it? Using a dishwasher vs. hand washing dishes: everything you need to know hand washing.
Does hand washing dishes use less water than dishwashers?
Yes, in the majority of cases, is the quick response to this. 9.5 liters of water are typically used by a standard dishwasher for each wash, compared to up to 60 liters for hand washing, claims a top manufacturer. It’s a significant difference.
Using the dishwasher instead of hand-washing the dishes can save a staggering 85% of water, according to a little math. Additionally, switching from hand washing to using a dishwasher can help you save up to 18,000 liters of water a year.
Is hand washing more energy-efficient than dishwashers?
Dishwashers also excel in terms of energy efficiency. Hand washing dishes results in twice as many greenhouse gases over a 10-year period as using a dishwasher, according to a recent study from the School for Environment and Sustainability at the University of Michigan. (It depends on your heating system because the energy required to heat the water is where most of the greenhouse gases related to hand washing dishes are produced.)
The same warning applies to energy efficiency as it does to water use: newer dishwashers are significantly more energy-efficient than older models.
FAQs
How Much Water Does a Dishwasher Use in Litres?
According to a leading manufacturer, a standard dishwasher uses around 9.5 litres of water per wash, while hand washing generally uses up to 60 litres.
