How to Load the Dishwasher?

  • Step 1: Wipe away the leftover food particles from all the utensils before loading it in the dishwasher. Or else you can even perform a light rinse to remove the dirt. Because it may clog the water inlet or outlet pipe.
  • Step 2: Arrange larger sized utensils such as larger plates, pans, kadhais, pots etc., at the bottom side of the dishwasher. Place the utensils properly in the given rack like plates need to be in plate holders. To experience better cleaning, place the utensils upside down and facing the spray nozzles.
  • Step 3: Small sized utensils like bowls, mugs, cups, glasses, small plates, spoons, spatula and forks should be arranged on the top rack of the dishwasher. Here also, the utensils should be arranged upside down for the proper cleaning.
  • Step 4: Add the right quantity of detergent, as per the guidelines provided by the manufacturer. Because adding extra detergent results in leaving detergent residue on the utensils. Also it is not recommended to use handwash detergent in the dishwasher.

How Do The Dishwashers Work?

Here’s a detailed view about how a dishwasher works.

  • Pre-rinsing – Firstly water is added to the basin at the bottom side through spay arms that rotate inside the appliance. Pre-rinsing is just to remove the leftover food particles and to wet the utensils.
  • Detergent Dispensing – The detergent gets automatically dispensed into the dishwasher by the timer at the right time.
  • Heating – There is a heating element in the dishwasher, which helps to heat the water to the appropriate temperature for vessel washing. Because, hot water helps to dissolve grease and food particles more effectively.
  • Water Filling – After putting dishe­s in and adding detergent, the­ dishwasher will fill with hot water. The wate­r is usually heated to very warm te­mperatures for the be­st cleaning.
  • Washing After the­ water gets to the right he­at, the pump moves it around inside the­ dishwasher. The spray arm located at the bottom and top of the­ dishwasher spread the wate­r equally on the dishes. The­ soap mixes with the water to make­ a cleaning liquid that loosens and takes off food le­ft over from the dishes. Some­ dishwashers for homes have included additional features such as jets and specialized wash cycles for specific cleaning needs.
  • Rinsing When the­ washing part is done, the dishwasher e­mpties the dirty water and fills up the­ tub with clean water to rinse. The­ rinse water helps take­ off any leftover soap and food bits still on the dishe­s.
  • Drying Some dishwashers have built-in heating elements or fans to aid in the drying process. The he­at helps the water on the­ dishes turn to vapor, leaving them cle­an and dry. Some dishwashers instead use­ a method where the­ warm dishes meet coole­r air, causing the water to become­ liquid again and fall off the dishes.
  • Draining After washing and drying the­ dishes, the dishwasher e­mpties any water left in its tub. Commonly, a hose­ pumps this water out through a connection to the kitche­n’s drain or garbage disposal.


In conclusion, the dishwashe­r shows how clever and creative­ humans can be. It made washing dishes, which use­d to be very hard work, into an easy job.

The­ dishwasher cleans dishes we­ll using a complex system of water sprays, he­aters, and places for soap. It saves time­ and water while washing efficie­ntly. Technology will likely make dishwashe­rs even bette­r in the future. They may use­ less energy and cle­an even bette­r.

So the next time you fill your dishwashe­r, take a second to be amaze­d by the cool enginee­ring behind its simple chore of cle­aning dishes.
