It happens that after washing in the dishwashing machine, the surface of the dishes remain murky divorce. Used for food, such devices can not. And there is such appliances is quite expensive, so users rely on high-quality wash. In this connection it is necessary to find out why the image of a white film on the dishes after the dishwasher to fix it and did not wash up devices once again.
There are several causes of divorce, are associated with the rigidity of tap water, the quality of detergents and technical problems.
hard water
A common reason that on the dishes are streaks - increased hardness of the water that enters the dishwasher. In a typical tap water has a lot of salts of heavy metals and other impurities. After drying the washed items appears on plaque, which form salts in the decay.
Dishwashing hot water is used, wherein such impurities are dissolved, and thereafter remain in domestic appliances and machine parts to form a white precipitate.
The content of metallic impurities in the water depends on the soil conditions in a particular region. The more there is of calcareous rocks, the harder the water is.
In most regions of the country water is very hard. This can be seen by how quickly formed scale in kettles and other appliances. Inside the dishwasher the same thing happens. Limescale covers the heating elements and other items than degrade the performance. If not eliminate, the machine breaks down, and it will have to be repaired.
To mitigate the aqueous stream ion exchange system installed in the dishwasher art. The water passes through the tank and with a special resin is softened to a normal index. To do this, in the engine compartment need to add refined saltWhich starts operation of the ion exchanger. In the composition means are sodium chloride ions to neutralize hard metal salts.
If the regenerating salt in the machine is not available, wash quality is getting worse, and then the system breaks down. Therefore, use of the salt required.
In many models of dishwasher technology has control water hardness. Before starting the machine, you need to adjust it to the optimum rate. The expensive multifunction models, it is automatically detected. And if such a function is not present, it is possible to carry out settings yourself.
Define indicators of water can be special strips, which are supplied to the unit. One end of the strip is necessary to lower the water and after a while the indicator will show its rigidity. If it is not supplied these tests, you can find out the record in the department of urban water supply.
Detergents
Another common cause of muddy streaks on the dishes may be of poor quality detergents and care agents, as well as the wrong dosage. White spots can appear as a result of:
- poor powder;
- poorly soluble tablet preparations;
- in the absence of rinse aid or of poor quality.
The only specialized drug should be used during the operation of the dishwasher appliances. Thus it is necessary to use all three means - washing, regenerating salt and rinse aid. Choose products of famous brands tested.
The machine can not fall asleep conventional detergents for hand washing, because they are not suitable for use in an automatic machine. This is due to the fact that higher temperatures are used in the machine. Therefore, do not replace a detergent other home remedies in order to save. Repairs to the machine in case of damage will be much more expensive.
Salt and rinse aid needs to be added strictly dedicated for them compartment. It is unacceptable to pour the rinse aid in the compartment for powder, as is done in washing machines. You also need to monitor the amount of medication. In many models of dishwashers have salt level indicators and caring means.
The use of the rinse solution is also important because it is responsible for flushing the surface of the dish with powder residue. After his instruments are clean and shiny. Only high-quality rinse warrants divorces and plaque.
many manufacturers tablet means 3 in 1 It argues that the use of the tablets can replace the salt, since it is already contained in the briquettes. However, regenerating salt should be added separately.
technical issues
Sometimes the cause of plaque and muddy streaks on the dishes can be a device failure related to marriage or substandard care machine. Among these problems occur:
- piecemeal construction compartment for the detergent;
- clogging the filter mesh;
- the formation of lime deposits on the heating elements;
- clogged sprinklers;
- breakage sensor water hardness.
When the cause of the blockage in the steel machine parts need to be cleaned. To do this, remove and clean the filters, drain hose and other collapsible parts. After such a cleaning necessary to start the washing operation with detergent. This will remove the plaque on the inside of the machine. Such procedures should be carried out regularly 1-2 times a year.
In case of failure of sensors or breakage of the machine is necessary to contact the service center. Repairing such equipment can only be a specialist.
When the divorce and plaque on the surface of washed dishes worth finding out the quality of detergents, their dosage and check operation of the machine sensors. And to extend the life of the dishwasher regularly to care for her.
