Hard water

If you notice on the dishes not just a white coating, but a milky shade, then be sure - the problem is water hardness. Most often, housewives forget or do not even know about the use of emollients for dishwashers. As already mentioned, hard water can be due to a water supply channel, and due to technical malfunctions of the system, and because of your indiscretion. But in any case, it is impossible to leave everything as it is, you need to look for a way out of this situation.


The solution to the problem that a white coating appears on the dishes after washing in the dishwasher due to poor water is also quite simple. Just go to the store and choose a softener for water.

Before buying anything, talk with other experienced housewives, search the Internet or consult with the seller, and only then buy a proven tool. For example, you can look at the products:

  • Calgonit;
  • Frisch-aktiv;
  • Largo
  • Somat.

Important! The emollient components for the dishwasher are very important. Therefore, neglecting such a tool is highly not recommended, because the risk is not only in the coating on the dishes, but also in the breakdown of the device itself. Hard water will very quickly spoil and slow down the washing process itself, making it less quality. So it’s better to buy an emollient immediately after buying a dishwasher, rather than hesitate and wait for stains on cutlery and plates.

Technical difficulites

Absolutely all equipment requires proper attention and care. A dishwasher is no exception. Due to a technical malfunction, the machine may become dirty, the water will become harsher, and the washing process will be longer and of less quality.

Technical problems resolved independently include:

  • damage to the sensor, which determines the hardness of the water;
  • the end of salt in a special container;
  • pollution of filters and the machine itself.


In case of contamination of the machine itself, you just need to clean it. This can be done simply by running an empty machine without dishes. In this way, she will cleanse herself.

Instead of a dishwashing detergent, it is worth adding a dishwashing detergent. If there is no such house, you can replace it with citric acid. It is added in an amount of 1-2 tsp. in a special compartment for salt.

Important! For prevention, such a procedure is best done once every six months. It is better to once again protect yourself and clean the machine, then to suffer from stains and plaque.

If the filters are clogged in the dishwasher, clean the filter yourself if it is dirty, but if it is large, it is better to buy a new filter and replace it.

The most difficult problem can be called a malfunction of the sensor. Such a violation occurs due to the improper dosage of emollients. Only a professional from a service center can solve this problem.
