Do dishwashers save water (including Samsung) versus hand washing? Surprising answer

Many of our mothers made us believe unless we are running a full load, running a dishwasher is a waste of electricity, water, and dishwashing detergent and salts. Our mothers encouraged us to hand wash a few utensils after the family dinner every night. However, these myths have been busted with research and testing.

Does using a dishwasher save water?

Most of the time after the family dinner every night, the number of plates, pots, cutlery, etc. which get accumulated almost is enough to run the dishwasher. It is a greener option to run a dishwasher every night.


How much water does a dishwasher use and do they save water?

If you think that since dishwashers are always spraying water, and hence use more water than hand-washing, you are grossly mistaken. Dishwashers have different pressure types and nozzles which optimize water usage.

If you use hand-washing to wash a load of utensils, it will consume about 27 gallons of water. However, to wash the same load in a dishwasher, you will need only 3 gallons of water. So a dishwasher is on average 9 times more efficient in saving water than washing it by hand. Of course, you will have to buy an eco-friendly energy star-certified gadget in the first place.

In 2013, the energy-saving commission in the U.S put new regulations and any dishwasher manufacturer cannot use more than 5 gallons per load.

If you live alone/only with your spouse/partner, and cannot fill up the dishwasher to its full load in one day, use the rinse and hold feature. You can pile up the utensils for two or three days at a stretch and wash those in one go. You might need to buy some extra utensils, however in the long run it will be beneficial. You will end up saving a good amount of money on your electricity and water bills.

Avoid water wastage in pre-rinsing

Now there are two theories working in favor and against this. On one hand, the dishwasher manufacturing companies mention, that the consumers do not need to pre-rinse the dishes before putting them in a modern dishwasher. However, most of homemakers and web articles will tell otherwise.

Many pieces of research and reports show that in the U.S, on average 6000 gallons of water is wasted every year due to pre-rinsing. The newer models of dishwashers can handle some titbits of food particles, and hence the companies are insisting that consumers stop pre-rinsing.

Now it depends on your model of the dishwasher, whether you want to continue with pre-rinsing or not. However, if you have a dishwasher that is more than 7 years old, it is time to upgrade.

Always use a good quality dishwasher salt so that the hard water can be softened and it does not leave any watermarks on your utensils. Using rinsing aids too help in getting squeaky clean utensils that you will not need to dry or rinse again. In the current times, there are all-in-one dishwasher tablets that include the functionalities of a dishwasher detergent and rinse aid. You may choose to try them too.

Do dishwashers use hot water?

Dishwashers not only save on your water bills, but they also save on your energy bills too. Unless you live in Miami, Florida/Houston, Texas/any other place where using tap water at normal temperature is fine to wash utensils, you are already spending more. You will need to turn on your water heater to use the warm water flowing through your tap for you to wash your utensils. You will end up spending extra on your electricity bills.

Most of the latest dishwashers have heaters fitted inside the electrical circuit, and they warm water more efficiently than your hot water heater. So if you are using an energy-certified dishwasher which in all probability you will be doing, you will save a lot on your electricity bills. A dishwasher uses half the electricity than washing utensils by hand.

In the past, dishwashers had to be connected to a hot water pipe but these times are gone as the machines have become more powerful. This makes them easier to install as well.

There are other reasons though why you might prefer to wash manually.

So using a dishwasher not only saves your time and manual labor, it saves you money too. Since water is getting scarce in all parts of the globe, we must look at ways to save it. Groundwater levels in every country have gone down to a large extent.

We need to protect the environment and start using solar panels to generate electricity. We should also do rainwater harvesting and water treatment to make optimal usage of water.

Conclusion: Does a Samsung dishwasher save water

During the daytime, especially after a modern-day breakfast, there will be a couple of coffee mugs, and cereal bowls will be accumulated. A frying pan (mostly used to fry eggs, bacon, and sausages) and plates will be added to that load post a family breakfast. If you have time to pick up the sponge and hand wash them before leaving for work, then it’s great.

However, most of the time they are kept in the sink and everyone runs to catch the school bus, metro, or drive to their workplaces. So once we are back from work, we see the same utensils lying in the kitchen sink.

Instead of washing those with your hand while your microwave or cooking pot is boiling the soup or potatoes, just wait for a little longer. It will be a good idea to leave them and add them to the load after your family dinner. And do not forget to add the lunchboxes of your children, spouse, and yourself.

Now since you have understood the positive impacts of using a Samsung dishwasher on a regular basis, start using it every night. It will be a good idea to pile all the utensils which you use in the entire day and fill up the dishwasher to its optimum load-bearing capacity. You can sit back and spend some quality time with your family and exchange about the day’s events while the dishwasher does the chore.

There is no point in wasting time doing household chores like washing clothes and utensils when a machine can do the same work. Countries like Japan, Singapore, etc. even have started using household robots that are capable of handling a vacuum cleaner and cleaning the house with minimal human intervention.

It is always a good idea to use that time to do something productive that a machine can’t do. Play a game of chess or Pictionary with your children while the machines do these chores. Read, a book, watch a web series or movie or do anything which entertains you. 

We have outlined here that dishwashers don’t use that much electricity.
