Do Dishwashers Save Water

Dishwashers are one of the handiest and convenient appliances in any household. By investing in a reliable dishwasher, the amount of housework that you will have to do will be drastically minimized.

However, it is important to note that certain dishwasher models can cost more than they are actually worth. If you have an older model, you are likely to spend a fortune every month on your water and electricity bill.

For this reason, it is essential that you look for ways to save money by reducing the amount of water and energy used on each cycle. In this article, we will be discussing how much water the average dishwasher uses and how you can go about saving water when washing your dishes.

Dishwashers Vs. Handwashing

It may be hard to believe, but even some of the biggest and oldest dishwasher models can be a greener choice than washing your dishes by hand. However, if you want to save money on your water bill every month, it is highly recommended that you look for ways in which to reduce the amount of water used on every washing cycle.

When you select a wash setting, the dishwasher is programmed to use a specific amount of water. This means that you can predict how much water you will use every month on washing dishes.

However, if you choose to hand wash your dishes, you will use more water to clean each individual dish. In the end, this makes the dishwasher a much more efficient and effective method of cleaning. This is especially true if you load the dishwasher fully.

How Much Water Does A Dishwasher Use?

So, just how much water does a dishwasher use on every cycle? This depends a lot on the type of dishwasher that you have and how old it is.

Most newer models use a lot less water than you may think. Over the past couple of years, releasing greener appliances has become a top priority for major companies. For this reason, you will be able to choose from a wide range of efficient models that will be sure to save you money every month.

When washing your dishes by hand, you are likely to use up to 27 gallons of water per load. With that in mind, some of the most efficient dishwashers use as little as 3 gallons of water for a full cycle. In the average household, this will save up to 5,000 gallons of water every year, drastically reducing your water bill.

Since 2013, a number of standards have been put in place to minimize the amount of water that dishwashers can use on every load. For this reason, it is highly recommended that you look into purchasing a newer, more modern model if you are on the market for a new dishwasher.

How Dishwashers Save Energy

It is also important to note that some dishwashers can actually end up saving you money on your energy bill every month. When you wash your dishes by hand, your hot water tank has to heat up the water to at least 100 degrees Celsius in order to kill any germs and bacteria effectively. This uses a lot of energy, especially if you are using 20 gallons or more per load.

On the other hand, modern dishwashers feature interior heaters that are much more energy-efficient. If you invest in one of these greener appliances, you can cut the amount of energy used per load in half. At the end of the month, this will end up saving you plenty of money on your energy bill.

Ways To Save Water And Energy When Running Your Dishwasher

So, how can you go about saving even more money on water and electricity every month?

Make Sure You Have A Full Load

The average amount of water used per cycle by dishwashers is between 5 and 10 gallons. This means that every time you set your dishwasher, you will be using this amount of water. In order to avoid using the appliance more than once a day, make sure that you fill the machine as much as you can. In this way, the same amount of water will be used to clean more dishes.

Don’t Rinse By Hand

When you rinse your dishes by hand before inserting them into the dishwasher, you use additional water. For this reason, it is highly recommended that you simply wipe off any leftover food using a damp cloth. This will save you plenty of money at the end of the month.

Don’t Overload Your Dishwasher

Overloading your dishwasher can result in some of the dishes not getting cleaned properly. This means that you will have to reset the dishwasher again or clean these dirty dishes by hand, which uses even more water. For this reason, ensure that every dish fits properly into the machine.

Turn Down The Heat

If you want to save extra money on your energy bill every month, try turning down the heat of the machine. Most dishwashers come with a number of cleaning cycles. Look for one that keeps the temperature below 110 degrees, as this will use much less energy.

Let Your Dishes Air Dry

Another way in which you can save energy is by letting the dishes air dry once the cycle is complete. Dishwashers dry the dishes by heating up the machine, producing steam. This uses a lot of electricity in the long run. In order to avoid this, simply open the machine once the washing cycle is complete and let the dishes air dry.

Choose Your Dishwasher Wisely

As we have already mentioned, there is a wide range of dishwashers out there for you to choose from. If you want to save money on your energy and water bill every month, it is highly recommended that you invest in a green appliance that uses less water and electricity.
