A dishwasher works automatically in such a way that it cleans utensils and dishes with the help of electrical power. It allows the users to place the used and dirty vessels in the dishwasher.
Several components inside the dishwasher such as spray arm, detergent, heating element, hose, etc. involve in the working process.
Have you ever wondered how does a dishwasher work and cleans the utensils with one-touch or push of a button? Read through the working of the dishwasher below to know about the entire process of how a dishwasher works.
How Does a Dishwasher Work
A dishwasher working generally follows a 7-step process such as adding water, heating the water, adding detergent, washing, draining, rinsing, and drying of the dishes. Let’s see about each step in detail.
1. Adding water – The first step in the working of the dishwasher is adding water to the machine. As soon as the machine starts it fills the tank or the basin with the required water.
2. Heating the water – Water in the tank gets heated up. The heating element or rod that is present in the tank heats the water that was filled. The rods heat up to a maximum of 70°C.
3. Adding the detergent – The machine is programmed in a way that it adds the right amount of detergent based on the tank capacity at the right time.
4. Washing the dishes – The spray arms in the dishwasher pumps the solution of water and detergent. With the force of suction power, the utensils placed inside rotates and the water shoots out on the dishes such that it gets cleaned perfectly.
5. Draining of the dishes – After the first wash in which the dishes get cleaned with the detergent, the machines drain out the dirty water.
6. Rinsing – Again, the water in the tank gets heated up. During this time, the machine does not add the detergent as utensils are already washed.
Now, the water gets to shoot with the spray arms in order to clean the utensils from any residue or soapy foam that was caused due to the detergent.
7. Draining of the dishes – Once again the unclean water gets drained out of the machine after the dishes are cleaned.
Depending on the structure of the installment, the drained waiter either foes under your sink or directly in the sink.
8. Drying the dishes – This step is optional based on the users’ needs. Only some variants of the dishwasher have the “Dry” feature.
This means that the user does need not manually dry the dishes. This option lets the utensils dry automatically.
The machine with the help of a coil heats the air and a fan blows this hot air throughout the machine which dries the vessels. Some people might prefer to dry the dishes manually to cut down the energy and cost spent.
Moreover, the dishwasher works in such a way that they are monitored by themselves as they are programmed automatically. A timer inside the dishwasher calculates the length of each cycle and operates accordingly.
The sensor senses the optimum temperature for air and water that prevents overheating or damaging the dishes.
Another water level sensor checks the quantity of water in the tank and prevents overflowing. Some machines even have sensors that detect the level of dirtiness of the water that would drain off.
The sensor works until the water is clean enough and lets the dishwasher know that the process is completed.
