White coating on dishes and in the dishwasher

dishwasher coatingThe dishwasher should wash dishes flawlessly, because we spend a lot of money on different tablets, salts, rinses, powders. But often the output is not what they expected. Plates and pans cover white plaque and stains, and not only that, even the walls of the dishwasher also have such a plaque. What are the causes of this unpleasant phenomenon, let's figure it out.

Reason One: Water Hardness

The main reason white plaque appears on the walls of the dishwasher or on the dishes is hard water. In such water, there is an increased content of calcium salts, iron and other impurities, therefore, when dried, a white coating appears. For this purpose, an ion exchanger with a reservoir filled with resin was built in the dishwashers. The ion exchanger is responsible precisely for softening the water, but to restore its ability to do this, you must regularly add special salt to the tank.Dishwasher salt

If you do not add salt, then after several cycles, you may not notice anything, thinking that the machine washes everything without salt. But it's not that simple! For some time, the ion exchanger will really soften the water well, but then it will make it worse, and with a long absence of salt it will break at all.

Having salt is not everything. You need to adjust the salt flow in the dishwasher, which depends on the hardness of the water in your area. Setting the water hardness is described in detail in the instructions for each machine, so be sure to read it before use.

Note! Some expensive dishwashers have a sensor for automatically detecting water hardness, the machine will determine the hardness and select a program.

The second reason: the quality and dosage of detergents

A very common reason when white coating appears on the dishes after washing is the wrong dosage of detergents, especially in cases where the region has soft water. White coating on dishes may leave:

  • poorly washed powder;
  • poorly soluble tablet;
  • insufficient rinse aid or lack thereof.

rinse aidPowder for the dishwasher is poorly washed off if it is poured too much, or the powder itself is of poor quality. When using powder, rinse aid must be used. It is important to correctly set the rinse aid consumption, most accurately, according to users, this can be done experimentally. Both overabundance and lack of rinse aid are bad. With a lack of white plaque appears, with an overabundance - excessive shine and rainbow film.

Important is not only how much rinse aid enters the washing cycle, but also where it is poured. Some manage to pour rinse aid with powder. As a result, the rinse aid is washed out already at the washing stage, and should come after the first rinse, before the final rinse cycle.

Pills of poor quality are washed off poorly, so it is worth replacing the detergent with a new, different manufacturer. Some note that the use of individual funds gives a better result, arguing that combined pills have an average dosage of substances. In real conditions, everyone has different water hardness, people load the dishwasher differently, and dishwashers are also different, hold different amounts of dishes, use different amounts of water. Detergents can be dosed, choosing the optimal dose for your dishwasher.

Important! Do not use dishwasher detergents or unverified home-made products. The result of such experiments can be not just white plaque and stains on the dishes after washing and drying, but also the failure of the equipment.

Some users of dishwashers note that white coating on the dishes remains when salt enters the chamber. For example, they accidentally sprinkled when they poured it into the ion exchanger, or the lid of the ion exchanger was not tightly closed, or maybe salt was poured together with the powder into the detergent compartment.

The third reason: malfunctions, violation of the operating rules

The appearance of plaque and stains on the dishes after washing in the dishwasher may be due to technical malfunctions. Such malfunctions include:

  • jamming of the lid of the compartment for powder and tablets, as a result of which the powder is poorly washed out or the tablet remains undissolved;
  • clogged dishwasher filters;
  • clogged holes in the sprinklers and reduced water supply pressure.

You can fix these problems on your own, without involving a wizard. Firstly, it is necessary to carry out a full cleaning of the dishwasher. Rinse the strainers thoroughly first, and then start the idle wash. with special detergent, which will wash away plaque from the walls of the machine, clean all openings from limescale, save the car from an unpleasant odor.

Important! Complete cleaning of the machine must be carried out at least twice a year, regardless of the intensity of operation.

As for the compartment lid, in some Chinese-built cars, the lid is poorly fitted and seizes when opened. To solve the problem, you can replace such a compartment or grind the lid with a file, adjusting the size.white coating on dishes

The compartment lid may not open properly due to improperly placed dishes that interfere with this. Even if the lid opens, if the dishwasher is not correctly positioned and overloaded, the dishes may not wash well, and do not be surprised that white deposits remain on the dishes after washing.

If you constantly sprinkle salt, use good and proven detergents, dispense them correctly and follow the rules for operating the dishwasher, but there is still a white coating in it, then the ion exchanger may break. It rarely happens. On models with a water hardness sensor, this problem may occur if the sensor breaks. It is difficult to diagnose such a breakdown, it is better to entrust it to a professional.

Thus, there can be many reasons why a white coating remains in the machine after washing. Most of these reasons can only be determined empirically by replacing detergents, changing their dosage, or by thoroughly cleaning the machine. If it was not possible to establish the reason, you must contact the service center.
