Let’s look for solutions together.

Causes of a bad dishwasher

  • the cleaning of the machine is carried out out of time;
  • unsuitable detergent or incorrect dosage;
  • improper use of PMM;
  • technical difficulites.

User errors due to which the dishwasher began to wash dishes poorly:

  1. Poor cleaning of dishes before loading. All manufacturers warn that appliances must be thoroughly cleaned before washing in the car.
  2. Incorrectly installed program. For heavily soiled utensils, an economical or reduced mode is not suitable. You should choose an intensive program that will cope with stubborn dirt.
  3. Incorrect placement of devices in the chamber or overload. Too dense arrangement of plates or the installation of large objects on top of small ones block the access of water. Place the dishes according to the instructions.
  4. Errors when using detergents, salt. Incorrect selection of “chemistry” or adding the wrong amount leads to an undesirable result. Change the agent or reduce / increase the dosage.

If you have already checked all possible options, but the dishes are also poorly washed, the reason may be:

  1. Scale. Hard water contains impurities that settle on the inside of the dishwasher. Limescale clogs the sprinkler holes, which interferes with the normal spraying of water. Installing a flow filter and using special salt.
  2. blockage. The inlet and return filters become clogged over time. Therefore, clean the parts.

Sprinklers

The upper and lower rockers are equipped with holes (nozzles) through which water enters. They are also clogged with limescale and food particles, so the technique does not wash dishes well. Remove them from their seat. Clean the nozzles with a toothpick and rinse with running water.

Temperature sensor failure

The latest models use sensors that monitor the temperature of the water heating. As soon as it reaches the desired temperature, the sensor sends a signal to the module to turn off the heating element. A new item needs to be installed.

Problems with the circulation unit

A pump or motor circulates the water in the chamber, jets under pressure against the dishes. The motor winding can burn out, then a complete replacement of the unit is carried out:

  1. Disconnect the machine from communications.
