A dishwasher is an appliance that washes dirty dishes and crockery. Using heat, water and detergent, a dishwasher hygienically washes dishes, achieving excellent hygiene results at home. Invented in the 19th century, the dishwasher is a revolutionary appliance that automatically cleans soiled items, saving the user valuable time. Yet, despite the numerous benefits of owning a dishwasher, widely accepted myths still exist around handwashing vs. dishwashing.

How a dishwasher works

Dishwashers work hard to ensure our crockery remains clean and hygienic. Yet, despite the importance of dishwashers in our day-to-day life, most people are unaware of how their dishwasher works. The process by which dishwashers clean are dishes is relatively simple.

  1. The shallow basin at the bottom of the dishwasher is filled with water.
  2. Heating elements in the basin then heat up the water. Depending on the wash cycle selected, the temperature of the water will vary. For example, our Intensive 70 programme reaches a temperature of 70°C.
  3. Detergent is then released and pumped through the machine’s jet arms. Thanks to the high levels of pressure in the appliance, the water has enough force to clean dirty dishes.
  4. Dirty water is then drained out of the dishwasher.
  5. The dishes are then rinsed with clean, hot water to ensure no debris remains. The water is then drained out of the machine.

Different dishwashers come with different wash cycles, meaning the above steps may vary depending on which cycle is selected. Before purchasing a dishwasher it is important to consider which cycles would benefit your lifestyle the most. For example, some of our dishwashers come with the Fast 45’ programme, which can wash and dry a full load in just 45 minutes, perfect for busy families. For more information regarding wash cycles, please read our dedicated dishwasher buying guide.

What are the benefits of owning a dishwasher?

The benefits of owning a dishwasher are plentiful. Not only is dishwashing is faster than handing washing, it is also more hygienic. To remove germs from household items, water needs to reach a temperature above 65°C*. Yet, when washing by hand, water typically reaches only 27.5°C.

Owning a dishwasher can also save up to 6800L of water per year.** With a Beko dishwasher, you can relax knowing that your appliance is reducing your water consumption. Some of our dishwashers consume as little as 9 litres of water per cycle and feature energy-saving Eco-cycles.
