But with the technology taking a turn to introduce convenience in everybody’s life, the dishwasher is here to your rescue. Just put your dirty dishes in the cabinet, click a few buttons, and voila! Fresh clean and warm dishes are ready to be used. This article will give you a brief idea about how does a dishwasher work.

But have you ever stopped to wonder how this magical equipment, the dishwasher works? If yes, then let us take a journey in the intricate world of the dishwasher that works to make your life easier.

Exactly What is a Dishwasher?

Before we go on to explain the working of a dishwasher, let us give you a brief idea about what exactly is the machine that you would be installing. Talking in simple terms, a dishwasher is a robot that is meant to clean and rinse dirty dishes. With separate racks and collection areas, you simply put in your dirty dishes, add washing soap, set the correct cycle, and simply turn it on. Once the process is complete, the dishes are in the same rack spotless and clean.

Steps Performed by a Dishwasher Once Loaded

  • Add the water
  • Heat the water to the appropriate temperature
  • Automatically open the detergent dispenser and operates it functioning at the right time
  • Creates the right pressure of water for a jet cleaning the utensils
  • Drains out the excess used up water for cleaning purposes
  • Spray out more water for one final cleaning
  • Drains all the water left in the system
  • Blows air on the dishes to give them the clean heated feel that we all love. 

These are some of the basic steps that every Dishwasher from every brand does in order to make your life in the kitchen a lot easier.

Also in addition to this, the dishwasher also works to monitor themselves to make sure that everything is working out properly. A timer installed within the machine makes sure that you can control and regulate the length of each cycle. In a similar process, there is also a heat sensor placed in the dishwasher to make sure that the air blown out on the dishes doesn’t get too hot. There is yet another sensor that monitors the fact that the water level is kept from overflowing. 

In certain dishwashers, you will even have certain sensors that will work to detect the dirtiness in the water that is coming off the dishes, which further helps it indicate when the dishes are finally clean enough to complete the process of rinsing. 

With this basic knowledge, let us take a look inside the machinery of a dishwasher and see how the machine actually operates. These days market is offering a lot of innovative kitchen appliances, to refer to and have a good understanding of the most prominent options available in the market. Here is a list of 10 best dishwasher in India that is available for you to purchase. 

A Look Inside The Working of Dishwasher​

If you imagine the look of the inside of a dishwasher, imagine yourself in a piece of watertight machinery that is surrounded by your dirty dishes. But this machine doesn’t simply fill up with water and lets the dishes immerse and clean out the food, it rather works on a slightly different approach. It is crucial to have a better understanding of how does a dishwasher work. 

It starts up with a heating element to warm up the water that will be used to clean your dishes. Once the water reaches a range of 130 to 140 degrees Fahrenheit, the pumps propel the water right up to the water jets and it is forced out and sprayed onto the dirty dishes. Now, this is not done with too much force that might end up harming your delicate trinkets, like wine glasses, rather working with a slightly forked spray. If it helps to understand, you can imagine a garden pipe with your thumb placed on the nozzle. Along with this, like the garden sprinkler, the force of water will also make the arms of the jets rotate making the dishes spin around for a more thorough cleaning. 

Once the process of the washing and rinsing is completed the water is drained out of the basin again. It is here that a pump is located to pump out the excess water to push out the water of the machine and start on the next aspect of the cleaning. There are some dishwashers that push the water right into the drainage pipe while some come up to the sink via a hose and then go into the drainage pipe, depending on your water connection. 

The final point in this cleaning process is the drying up of your dishes. Now the thing to note here is that not every device comes with this option to the optimum level so there is always a choice to skip or use this. The same heating element located at the bottom of the machines is used to heat up the air trapped inside the device to help your dishes dry up. For the nature conservationist, there is always the option of letting the dishes dry without turning on the heating feature, saving up the additional energy used in it. 

Thus the simple process of this complex-looking yet very simple machine is complete and the dishes are ready to be stored in the racks.

Parts of a Dishwasher

Now that you understand the basic working of a dishwasher, let us discuss the main parts without which the machine would not be able to operate.

        1. Control Board

One of the major aspects of this machine is the control mechanisms that are located just inside the door behind the control panel. This is most machines means a simple electro-mechanical system including a timer to determine the length of each cycle and controls the proper timing of each function accordingly (like we discussed above), including the main functions like the detergent dispenser, the water spray feature, and the draining of the subsequent water collection. As the price range of the product increases the option for a computerized control system comes into play that will give you more options for control. Another common feature with the more high-end models is the door latch that will stop the operation of the machine till the time the door is not closed.

        2. Valve for Intake

In simple terms, this is the place where the water would enter the machine. The pump located in the valve is not used to pump the water out of the machine, but rather when the intake valve is opened, the water is taken from the water connection and enters the machine.

        3. The Pump

The small version of electrical water is powering the pump. During the time of the pump cycle, the small device would pump up the water in the place where the sprays are located. Similarly, when the point of water drainage comes, these same pumps are used to direct the water flow towards the water discharging hose. This means that there is more than one type of pump.

  • Reversible pumps: The same type of pumps are used for both directing the water flow to the spray arms and the drainage area when the time comes. nyms of responsible
  • Direct Drive pumps: The pumps that pump the water in a singular direction. When the time to reverse the flow comes it is done using a Solenoid.

11 Tips to Make Your Dishwasher More Effective

If every part of the cleaning process is taken care of by the dishwasher, what are you to do in that process? Well, you are not completely without any duties, and let us tell you exactly what. These tips will help you to ensure and guide you with how does a dishwasher work. Here are some things to help you make sure that your machine can do all the cleaning with even more efficiency.

1. One of the most important things to make sure is to never use the normal dish soap you use while washing dishes with your hand. The suds formed by those will end up overflowing the entire machine.

2. Maintain a limit of the number of dishes that you put in your dishwasher in a single wash, which will make sure that the cleaning is done properly. Overloading your dishwasher will make the sprays of water ineffective which will compromise the cleaning.

3. Arrange your dishes in a way that will make the dirtiest part face the direction of the jet sprays. This will make sure that the things stuck to them are cleaned thoroughly. Most of the dishwashers, this is located in the center of the machine. 

4. Do not ever mix up your steel and silverware together. Though they may look similar in build and wear quality, putting up two different metals together in a humid climate is the perfect recipe for disaster and can end up causing corrosion. 

5. Whenever you are arranging a lot of similarly spaced utensils, like the bowls and spoons, try to keep these as far away in the machine as possible. Once kept together, they may end up nesting in each other by the rotating motion of the machine and the water may not reach the utensil on the back. This will not only make cleaning difficult but can also collect all the water-soaked organic food debris in the utensils, which is just gross to look at. 

6. Never try to clean the delicate cutlery, like your wooden boards and mugs, your cast iron pans, the fine china made only for the guest, or even your prized crystal or hand-painted dishes in the washer. No matter how gentle the cycle the company boasts, a dishwasher can and will end up compromising the quality of your favorite items. 

7. Always pick a time of the day when your water flow is high to wash the dishes, like late at night just before going to bed. This will make sure that the machine can pump the water in a way that will clean your dishes properly. 

8. If you live in a mountainous area, or simply a place with a hard water supply, make sure that you put in a little extra than the recommended amount of the detergent, as it takes more amount of soap content to bring the froth with hard water. This will make sure that your dishes are not slimy. 

9. Always turn on the Rinse Aid feature provided by most dishwashers for a better-aimed cleaning and better drying up of the dishes. 

10. When cleaning up the plastics in your home, always make sure that you don’t end up placing them on the bottom of the rack especially when you are using the hot drying cycle. Since the heating up of the machine usually takes place on the bottom, the lower rack is always more susceptible to burning and melting the plastics. 

11. Do not try to pre-clean the dishes before putting them in the dishwasher. A lot of the functioning of your dishwasher is made keeping the bits of food that are clinging to the dishes to maintain the appropriate cleaning pH in the machine. This, however, doesn’t mean that you can be leaving big pieces of uneaten food on your plate, for example, chicken bones. This would get stuck in the pump and can end up harming your device rendering it useless. Just make sure that you throw them away. 

A Dishwasher Buyers Guide (how to Choose a Dishwasher?)

Though the basic worksheet of all the modern dishwashers always resembles the same pattern, to help you find the perfect fit for your home, it is important to consider a few things. Here are these things to consider before you go ahead and invest in the device. The dishwasher’s buying guide will give more understanding regarding how does a dishwasher work and its features.   

  • The size of the device

One of the most important decision-making factors when it comes to buying a dishwasher is considering the number of dishes you need to wash and how many people the machine is catering to. The smallest option of dishwashers is the in-sink ones that use up to one-half of your double kitchen sink and can complete the cycle of a complete load in about 20-25 minutes. 

The second option is the moderate 24-inch dishwasher that comes to deal with a normal home size use and can handle the daily needs of 3-4 people. Some companies even offer 18inch units, often called the apartment unit, with a capacity of 2-3 people. If you come from a larger family with 5 or more people then the 30-inch model is the one for you. If we go above that, there are dishwasheControlrs in the commercial section which are often used in restaurants.

  • The quality of equipment

With the rise in the price range, the range of features also increases and one of the best examples of this is the quality and design of the basins and racks. The lower-end models usually come with a plastic basin while the mid and high-range models come along with a stainless steel option. 

Another feature is the filter for cleaning the food debris. In the lower end and even the mid-range ones, you would be required to manually clean the filters out, however, the more expensive ones come along with a self-cleaning filter that comes along with the small grinders that mince the debris to flow out along with the water. 

Speaking in simple terms, the more money you invest in your dishwasher the number of advantages and controls would be better.

  • The extra perks and controls

Controlling the process of cleaning to what level is allowed by the machine is another important factor to consider before going ahead with the purchase. The cheaper models often come with a mechanical control panel that will have a dial and timer to regulate and set different time settings. The expensive ones come with a simpler push-button control but don’t affect the cleaning capacity of the machine. 

There are some machines that come with the option to control the cornucopia of the options of the cycle such as the heavy-duty cleaning, or soft cleaning of crystal and china, or the latest addition of sanitizing modes. Some other extra features can be better designs imitating a kitchen cabinet and noise suppression keeping the hum to a minimum. 

  • Energy Use

With the world entering a place of rapid pollution it is also important to make sure that you do your bit to keep our mother Earth healthy. This is why you should always check the govt sanctioned Energy Star rating, which will not only indicate the working of your model but also how efficiently it uses energy.


It is always important to make sure that every device that you are introducing into your house can tick off all that you need from it. And to make sure that happens, we have compiled a list of how to find the one for you. Make sure you consult!
