Installation cost, energy consumption, space constraints and inefficiencies are some of the main problems with this machine.
According to Forbes, the cost to have an average dishwasher is about 970 USD (about 22 million VND). In addition, homeowners also need to spend additional costs such as detergent and electricity. Keep in mind that dishwashers can save water, but use significant energy to heat water to a temperature that can be disinfected.
In addition, dishwashers have the disadvantage of not being able to wash large items, so most with large pots, you definitely have to wash them by hand. Dirty, greasy, crumbly dishes, cooking equipment and utensils may also need to be pre-washed by hand.
In addition, dishwashers do not always clean effectively. Don’t be surprised if the plate has spots, streaks or food still on the plate, it’s not uncommon. Another thing to keep in mind is that an automatic cycle is also time consuming. If you need the bowl right away instead of waiting hours, washing by hand is preferable.
Dishwashers are also said to be bad for your health. A study published in the journal Food & Wine (Sweden) has shown that washing dishes by hand is healthier. The researchers found that diseases related to the immune system in children aged 7-8 years, including asthma, eczema or certain allergies… were less than in households without using devices. to wash dishes. They hypothesized that frequent exposure to the bacteria could be a factor in the development of immunity.
