1. Why is it not clean

In principle, if the dishwasher is used correctly, the washing effect will definitely exceed that of manual washing, but there are also cases where the bowl machine is not clean. In addition to some skills of tableware placement, the following reasons can be investigated:

Normal dishwashing powder is not used. Other non-professional detergents were used;

the filter is too dirty. It has not been cleaned for too long or has been blocked;

improper washing method. Tableware is too dirty, but a short and weak washing mode is selected. For example, the economic fast gear is set for quick and energy saving, which is not suitable for normal cleaning and will lead to incomplete drying.

The water softener leaks salt, and there is obvious white salt film on the surface of tableware, especially on the surface of glass;

the drain pipe is installed incorrectly. Spread it on the ground or insert it too deep into the sewer pipe, and the washing water in the dishwasher is drained.

put the dishwashing powder at the wrong time. It should be put before the dishwashing program is started, so as to ensure the dishwashing effect. Do not put the dishwashing powder in the pre-washing program section, because the general pre-washing is just slag washing;

second, how to use the dishwasher correctly?

1. Know the hardness of water

If you are in a northern city, you'd better use a dishwasher with soft water function and replenish soft water salt in time, otherwise, the washed tableware and dishwasher compartments will easily leave white water stains, which are not easy to clean. If the water is soft in a southern city, you don't need soft water.

2. Don't carry too many sundries

Dishwashers can't completely replace manual labor, so before washing, it's best to clean up other sundries in the tableware, such as fish bones, leftovers, rice, etc. Otherwise, it is easy to block the filter screen or hinder the rotation of the nozzle, which will affect the washing effect. Wash the tableware as soon as possible after use, and don't let the residue dry. Always keep the dishwasher clean inside and outside. After using it for 2-3 times, it is best to brush off the dirt and deposits on the filter with a brush to prevent clogging.

3. Placement of tableware is very particular.

Generally, some glasses, teacups, cup holders, small bowls and small dishes are placed in the bowl basket. Knife and fork baskets are generally placed with knives, forks, spoons and chopsticks, and the tip or blade should be avoided to avoid stabbing people;

large tableware such as big plates, large bowls, pots and pans can be placed in the lower bowl basket. Be careful not to put too many tableware in the washing basket, do not overlap and collide with each other, and the tableware cannot be exposed out of the metal basket, nor can it block the rotating motion of the spray arm, otherwise the cleanliness will be affected.

smaller cups, spoons and other utensils should be placed firmly to avoid falling and collision, so as not to be broken.

If necessary, you can use a smaller basket to hold these gadgets, which will be safer.

4. Aluminum products that the dishwasher may not be able to wash may fade or darken; cast iron products, tin products and tin-lead alloy products are prone to rust; copper products that are not washed together with silver products or stainless steel products may change color; the surface of rusty gold products is prone to change color; disposable plastic products cannot stand cleaning; products with adhesive handles may come loose after washing; lead crystal glass products may be worn or etched; non-tableware products, such as electrical appliances, Air filters or brushes will pollute or damage dishwashers and wood products. Unless it is indicated that they can be washed with dishwashers, they will easily bend, deform or crack. Non-stick coatings are not included here. For example, non-stick pans can be washed.

5. Don't use ordinary detergent

Dishwashers actually don't need detergent, but in order to wash dishes better and eliminate water spots, special dishwasher detergent should be used to clean dishes. The special detergent is characterized by low foam and high alkalinity, so it can't be washed directly by hand to avoid burning the skin. Remember not to use ordinary detergent, foam will overflow the dishwasher. In addition, dishwashing powder and rinsing agent are corrosive and should not be touched by children.

6. Choose the correct washing program

At present, many dishwashers have set 5 or 6 washing modes, so you can choose the appropriate washing mode according to the specific situation of washing dishes, which can greatly improve the washing efficiency and realize the effect of energy saving. For example, strong 7-degree washing: the highest washing temperature of the dishwasher is generally about 7 degrees, which is the most effective mode of cleaning; Automatic 45-65 degrees: the dishwasher judges the washing temperature and time by sensing the turbidity of water; Standard 5 degrees: fully soak the tableware, and use the least water and electricity to achieve the purpose of cleaning; Crystal penetration of 4 degrees: washing and shining for exquisite tableware; Quick wash 45 degrees: quick cleaning, suitable for light oil and low pollution tableware;

in addition, the dishwasher consumes a lot of electricity when drying dishes. If we don't rush to use the cleaned tableware immediately, we can use natural ventilation and drying as much as possible, which can reduce energy consumption.

7. Be careful to burn the dishes and chopsticks after washing

Don't touch the visible heating tube immediately after washing, so as not to burn them

8. If possible, it's best not to use the dishwasher as a disinfection cabinet

Although some dishwashers have the function of high-temperature washing and disinfection, they can't avoid the humid environment in the dishwasher, which is still easy to breed bacteria after a long time. Moreover, dishwashers are used every day, and it is not convenient to store dishes and chopsticks.
