1. Dishwashers Consume Excessive Water
Dishwashers use high-pressure water jet systems to clean dishes. Moreover, the perception that dishwashers consume significantly more water than manual washing is common among users.
However, according to Cnet, the actual water consumption of dishwashers is quite different. Test results show that users consume approximately 30 liters of water for families of 4 or more. In cases where rinsing mode is used 2 to 3 times with a full sink, water consumption can reach up to 100 liters.
If a dishwasher is Energy Star certified, the water consumption per wash is 11 liters, which is one-third the amount of water used in manual washing for an equivalent number of cups and dishes. These certifications, recognized by the U.S. Natural Resource Conservation Council, are estimated to save 18,900 liters of water per year for a household.
For example, dishwashers post-1994 certified models use approximately 37 liters less water per wash compared to previous models. Dishwashers certified since 2013 have a maximum water consumption of 18.9 liters per wash.
2. Dishwashers Consume Electricity
Many users believe that the more modern a dishwasher is, the more electricity it consumes. This belief even exists among users in the United States.
Because to have clean dishes when washing by hand, users often have to heat water. So, the electricity consumption should also account for the use of hot water.
For dishwashers, they are mostly equipped with internal heating elements to efficiently warm water compared to using hot water manually. Moreover, Energy Star certified machines help save costs by half compared to handwashing with hot water.
3. Pre-Rinsing Before Loading into Dishwasher
Manufacturers only recommend disposing of large food scraps into the trash to avoid blockages. Especially with small food scraps, dishwashers can handle them completely without user intervention. Therefore, it's not necessary to pre-rinse dishes before loading them into the machine.
4. Use Dishwasher Only When Washing Many Dishes
Cnet has pointed out the importance of comparing water consumption levels based on the amount of dishes and cups filling a dishwasher. Therefore, users should choose a dishwasher model according to their family's needs to avoid waste.
Nowadays, there are many new dishwasher models with half-load features that consume between 6 to 7 liters of water if users opt for fewer dishes. Additionally, many dishwashers feature accumulative washing, meaning they only do a preliminary rinse during the first cycle and complete the full wash cycle once the dishwasher is fully loaded.
5. Arrange Dishes in the Dishwasher
You must arrange dishes in a way that ensures proper spacing between items to allow the water spray system to effectively reach dirty dishes without difficulty.
Following this rule, glasses and cups should be placed on the top rack. In the case of washing glassware, wine glasses should be separated to prevent them from touching and potentially causing breakage. As for the knife holder, it's best to alternate the direction of the knife handles to ensure there's a gap for water to flow without causing dishes to get stuck or topple over.
6. Pouring Water Directly onto Dishes
Some individuals believe that using highly concentrated dishwashing detergent and pouring it directly onto dishes will enhance cleaning efficiency. However, this method may prevent the dishwasher from rinsing off any remaining chemicals on the dish surface. Chemicals present in the utensils can seep into food during meals, posing health risks to the family.
