Dishwasher Technology: A Short History
Have you ever wondered who came up with the concept of a dishwasher? It may seem like a recent discovery but the technology dates back to 1850. Of course, the mechanism was much simpler back then and the machine was made of wood. Joel Houghton was the first person who made a device that could pass off as a primitive dishwasher. The machine was unreliable and inefficient. Over the years several people have contributed to developing this appliance.
Josephine Cochrane is an extremely important name when it comes to dishwashers. This extraordinary woman was way ahead of her time. She revised the model in the year 1886 along with George Butters. Josephine had adequate knowledge about machines and engineering and she came up with an automated dishwasher. She had created history when she devised this incredible machine that was capable of cleaning utensils without any human input.
William Howard Livens was working on his model in the United Kingdom in 1924. The design was capable of running without electricity and was quite efficient. It is the modifications of this design that is seen in the modern dishwashers. He mainly incorporated three elements in his machine. First, a small front door which was used to load the utensils, strong, and reliable racks to place the items and a sprayer to supply water. This successful model did not win much appreciation and barely had any effect on the commercial markets.
The 1990s witnessed dishwashers in its full glory. This technology had become a rage and almost everyone wanted to buy one. The models launched with special energy conservation technology. Several companies that were already manufacturing electrical goods jumped into the scene. A dishwasher seemed like a good investment, and it was. People were extremely thrilled with this innovation. Since then dishwashers have been in use in several households. The innumerable advantages of the appliance have made it popular across the globe.
How to use Dishwasher
Using a dishwasher does not require a lot of not. It is not rocket science and you can learn to use a dishwasher correctly within a day or two. However, some things you should keep in mind while using the machine.
The first step is to understand your dishwasher completely. These modern devices come with a lot of options and features, you have to completely understand what the machine is capable of and use them accordingly. Read the manual if you have one.
The next thing is the soap and soap compartment. Locate the soap compartment and observe it carefully. Usually, there is a lid on the compartment. You will have to open the lid, pour in some dishwasher soap, and then close the lid so that the soap does not spill. You can use either a liquid solution or a powder to use as a soap but make sure it is not too harsh and not too old. If your detergent has been lying around for quite some time, chances are that it will not do the job satisfactorily. Therefore, buy packets that you can consume within a couple of months.
One of the most important things that you should understand before using a dishwasher is how you should place your utensils so that each of them receives an optimum amount of water. Place the dishes and bowls on the bottom rack. Do not place them too close to one another. Leave some space in between the plates so that water can reach every part of the utensil. Place the bowls at an angle so that water can reach the inside as well as the outside of the bowl. Place glass and fragile items on the topmost rack. Leave a considerable amount of distance between wine glasses so that they do not break.
Do not place spoons too close to each other. When you are loading forks, make sure the side with the tines facing upward. If you want to place some knives into the washer, make sure the blade faces downward.
After the process is complete, the water is expelled with the help of a pump fitted into the machine. Different dishwashers take varying amounts of time to drain the water completely.
Improvements to Dishwasher Energy Efficiency
The dishwasher manufacturers have come up with notable upgrades with every model. Earlier, using a dishwasher was extremely expensive and therefore, impractical. With time, the designs become more rational and practical and now a machine uses both electricity and water optimally.
Modern dishwashers use about 2000 to 2400 watts of electricity per hour. The average amount of water that the appliances use per wash is about 3 to 5 gallons. If you are someone who needs to run the dishwasher for more than one hour, naturally it will consume more energy. Studies have concluded that more or less, every household uses a dishwasher twice a day. To be more precise, a dishwasher is loaded 512 times in a year. If we do that math, it would require us to multiply the time consumed by the dishwasher with the electricity consumed per wash.
Appliances that are marked with a star are more energy-efficient and make clean utensils effectively without wasting electricity or water. Appliances that have the Energy Star symbol on them may use up to 30 percent less electricity than any ordinary machine.
Electric Resistance Booster Heat
Dishwashers typically use hot water to rinse and clean dirty utensils. The heater is installed within the appliance and you do not have to worry about purchasing a heating system for your dishwasher separately. This heating system installed within a dishwasher is called a booster heater. A resistance coil controls the temperature and is responsible for heating water. The water can reach a temperature of 60 to 80 degrees Celsius when a booster heater is used. Now, you may think why does a dishwasher need hot water? The heat from the water sanitizes the plates and utensils placed within the machine. We have all come to acknowledge the importance of sanitization and hot water can be an excellent sanitizer. Dishwashers that do not have a booster heater, rely on chemicals to sanitize the items. Though no serious illnesses have been reported, it is best to stay away from harsh chemicals and depend on good, old warm water.
Dishwashers with booster heaters have several advantages. As the temperature of the water is quite high, the water will evaporate quickly leaving your utensils dry. Therefore, you do not have to waste a lot of time drying your utensils. You can use your plates and bowls within a few minutes of washing. Another advantage of water booster heater is that it does not use any chemical to clean and sanitize your products. Many dishwashers that do not have a booster heater reply to harmful chemicals like iodine and chlorine. Usually, these chemicals are not too harmful but it is better to be safe than sorry. Some metals present in your utensils may react with these chemicals and become toxic. These appliances are easy to use and environmentally friendly.
Tests on Three Modern Dishwashers
We tested three different models of dishwashers to understand how the price of each model is related to its efficiency. Before investing in any appliance, it is important to understand all the specifications of each model. The market can be a confusing place and you may face difficulty in selecting the best dishwasher for yourself. Therefore, we tested some of the best products and reviewed them carefully. The main aim is to determine which features are absolutely necessary and what is the best deal consumers can get when they purchase a dishwasher. Our experts took their time with each machine to understand the mechanisms and the features that they come with. Here we will discuss which models we tested and all about its performance and efficiency.
The first model we picked was Bosch 300 Series SHSM63W55N. The packaging looked impressive and the features seemed promising. The stainless-steel frame and design of the machine looked quite ravishing. Upon investigating the features of the appliance further we came up with several important observations. The machine is extremely quiet and runs smoothly without making any unpleasant and disturbing noise. The Bosch 300 has become a favorite amongst many people and the model is definitely living up to its expectations. The racks within the dishwasher can be adjusted according to your will. If you want to place more bowls, you can adjust the rack accordingly. The 3 racks can be used to create as many as 16 different settings. The machine comes equipped with powerful water jets that expel water with high force and remove the most stubborn stains from your utensils. The price of this impeccable machine ranges from $700 to $800 depending on where you buy it from. Bosch has done an excellent job with this new dishwasher model.
We also experimented with one of the cheapest dishwashers. The results were impressive. We used Frigidaire FGID2466QF to clean some of our utensils. This machine may not tick all the boxes but the modest price point more than makes up for all the features that are lacking. It may not be the best but the model does an excellent job at washing dishes. The dishwasher looks polished and sophisticated with all the hidden control buttons. The upper rack is adjustable allowing you to place taller or bigger items. The racks can be altered to create 12 separate settings. The high temperature generated within the machine efficiently sanitizes all your utensils. The appliance is more than sufficient for $430.
The final appliance that we tested is the Thermador DHDW870WFM. This machine is expensive and comes with top-notch technology and it is worth every penny. If you do not like soggy dishwashers that accumulate a lot of water, this is the model for you. The zeolite technology efficiently dries the utensils and dishes so that you can use them as soon as the machine finishes. The interior is attractive and has a futuristic look with hues of blue. If you like fancy appliances, get your hands on Thermador DHDW870WFM.
Summary of Comparative Performance
All three models were extraordinary and the unique features in each of them were commendable. Bosch 300 Series SHSM63W55N performed extremely well and gave no reasons for complaint. The price point and the features are perfect. The model is one of the most efficient dishwashers. Frigidaire FGID2466QF is nice and sturdy. This would be a great model for beginners and people who do not require the dishwasher much. However, Thermador DHDW870WFM uses a lot of electricity because of the zeolite feature. Our recommendation would be to let the utensils air dry. Before buying any model check out all the features carefully.
How Much Dishwasher Water Is Actually Heated by the Water Heater?
A dishwasher uses hot water to clean utensils. A typical dishwasher will use 4 to 6 gallons of water with every use. Heating 6 gallons of water uses a lot of electricity. It usually uses 1.60 kilowatts per hour to heat 4 to 6 gallons of water.
Recommended Practices to Reduce Energy Use
Not making smart choices can land you in difficult situations. There are certain things you should keep in mind while using a dishwasher. These tips will improve the efficiency of your dishwasher and save you both time and money. Here are some recommendations for you:
1. Avoid Empty Spaces
A good thing to remember when you use the dishwasher is to always load it completely. You do not have to wash every utensil right after you use it. If you stay alone, you will not need many bowls, cups, or plates, so a good idea is to wash all the utensils together at the end of the day. This way you can save money by washing it all in one round. If you have a family then you will probably need to wash several plates and bowls. Whenever you use the dishwasher, make sure it is fully loaded and there is no vacant spot.
2. Select Smartly
You can save a lot of money on your electricity bill if you choose the correct model. Do not get tempted by modern features and state-of-the-art technology. Buy a model that suits you and fulfills all your requirements. You do not need an appliance with extremely advanced technology. Try to judge before buying whether or not the price and the features balance each other out. Buying an expensive model out of impulse can burn a hole in your pocket
3. The Correct Detergent
Selecting the right cleaning agent can be a game-changer. Use a detergent that is smooth and can clean efficiently. This way you will not have to wash your utensils more than once. Choose a powerful cleaning agent that can take off all the gunk and dirt in one wash. You can go for a liquid or a powder detergent depending on your preference. You may also choose detergents that do not contain any harmful chemicals like phosphate. Biodegradable and environment-friendly cleaners are the best.
4. Do Not Get Your Hands Dirty
You may have to fight the urge to rinse your utensils once before putting it into the washer. We all have done this at least once. Pre-rinsing your cups, plates, and dishes wastes a lot of water, energy, and time, buy a model that is powerful enough to clean your utensils effectively within the machine and in one go. Let your machine do its job. Instead of washing your dishes, you can directly discard the leftover on your plate into a dustbin.
5. Air Dry It
Some machines come with in-built drying technology. Models of dishwashers are fitted with special elements that promise to completely dry your utensils within the appliance. However, this uses up a lot of energy and results in a considerable increase in your electricity bill. A simple way to avoid this is to just wait and be patient. After your dishwasher has completed its task, let the utensils rest for a bit in the open air. Allow the natural circulation of air to dry your plates and bowls. This can save a lot of electricity as well as money. Usually, the warm water evaporates quite quickly, so you do not have to wait that long after all.
6. Use a Lower Heat Setting
Some dishwashers come with booster heaters. These are usually used to heat the water within the machine. Sometimes, the boosters heat the water excessively. The temperature may rise to 180 degrees Fahrenheit, which is extremely unnecessary. This wastes a lot of energy. Instead set the temperature lower, at around 1220 degrees Fahrenheit. This cleans the dishes efficiently and does not waste electricity. Save both energy and money by adjusting the temperature of your water. If your water is already heated due to a hot climate you may turn down the thermostat temperature further lower.
7. The Size
The Size of the machine you purchase plays an important role in determining how efficient and cost-effective the appliance will be. A dishwasher that is too large with extensive capacity may waste a lot of energy as the extra place will go vacant often. Buy a machine that can adequately fit your utensils without leaving any vacant spaces. The perfect size is one that has no extra space and can accommodate all your utensils without damaging them.
8. Read the Manual
Using an electrical appliance correctly is essential. It may not look like a big deal to operate a dishwasher, but modern technology comes with a lot of twists and turns. We advise you to pick up that manual and start reading. If that gets too boring, look up videos online that explain how to use a dishwasher efficiently. Using it the correct way will save energy and clean your utensils better. Once you have completely understood the process, take a few minutes to look at your appliance to figure out all the details.
9. Choose an Unconventional Time
Companies charge more during peak hours. Try to pick an unusual time when you think not too much energy is being consumed by people. This is an easy way to save money. Electricity companies increase the rate during busy hours. Every unit will cost way less if you pick early morning or late nights. Keep track of when the rate goes up and avoid using any heavy appliance during that time. You can load the machine whenever it is comfortable for you, for example, after lunch or dinner, but do not turn it on. If you wake up in the middle of the night or early the next morning you can start washing your utensils.
10. Energy Saving Mode
Many appliances come with a unique option called energy-saving mode. When the system works under the energy-saving mode, it automatically adjusts itself to consume fewer units of electricity. For example, it turns down the temperature of the water and switches off the dryer. You may also use the auto-shutdown mode available in some models. Both these features are designed to save energy while at the same time allowing the machine to work efficiently.
These are some of the easy tips and tricks to save money and electricity while using a dishwasher.
Advantages and Disadvantages of Using a Dishwasher
1. Save Time
Washing utensils one by one is a tedious task. It takes a lot of time and energy. Most people do not have that kind of time to waste. Therefore, buying a dishwasher is an easy option to get the job done without spending an awful amount of time on the tiring and boring task. You can engage in other meaningful and productive activities now that you have some extra time on your hands.
1. Faulty Placement of Utensils
Using a dishwasher demands you to place the utensils correctly. If they are too crowded or are not placed at the correct angle the machine may not be able to clean them properly. You will have to put the dishes in the washer again and again until you get it right. This wastes water and electricity. Therefore, it is best to read the instruction from the manual or watch videos online to understand how to correctly place the plates, bowls, cups, spoons, and forks.
2. Keep your Utensils Safe
It is quite natural to make a human error. While washing utensils, your hand may slip and you may break your favorite bone china. With a mechanical device, like a dishwasher, you can avoid this problem. Just place the utensils properly within the appliance and you can tension free. Use your bone china whenever you like without worrying about washing it. a dishwasher can handle bone china, wine glasses, silver utensils, and several kinds of materials.
