Dishwasher dries the dishes: the cause and repair

click fraud protection

At the final stage of washing dishes dried to shine. After that, the hosts is to place The washed utensils in the headset until the next use. Things are worse when the dishwasher does not dry on the dish are traces of moisture, stains are formed. You can get out of the situation in the old and thoroughly work the towel. But the problem does not resolve, the dishwasher needs repair.

It should be mentioned in all cases evidence of malfunction humidity dishes. Many low cost devices are equipped with means of drying condensation type. Drying occurs due to the temperature difference:

  • after washing dishware is rinsed with hot water;
  • its temperature rises above ambient;
  • crockery dries as it cools down.

A side effect of this method of drying is condensate which may settle on the tank walls and to the dish surface. It may seem too damp, especially if you open a car wash before the time. To prevent condensation on the recommended drying time slightly lifts the front door, some models are equipped with automatic opening when in this mode. Another thing, when the device is equipped turbosushki system. Here too wet stock is a clear sign of a malfunction.

sources of damage

Developers and manufacturers of dishwashers tend to maximize the reliability of its vehicles. But it does not guarantee one hundred percent "foolproof", does not prevent the normal wear and tear, exposure to external technical factors. Therefore, when the dishwasher under such famous brands as Bosch does not dry the dishes should be possible to ascertain the causes of failure. The most likely of these are:

  • failure of the heating element;
  • failure of the temperature sensor;
  • faulty control module;
  • inoperability fan, forcing the air heated in the tank (termosushka);

Heating element

Determine why the drying mode does not work, self-help system. In case of breakage of the heater on the machines Bosch equipped with a display, a fault code is indicated by E09. His absence will require independent verification of PETN on the performance:

  • you must disconnect all communication connections and power;
  • provide access to the bottom of the device;
  • dismantled pallet, after removing the drain pipe with pump;
  • check sensor and visual inspection with a multimeter, it testifies to serviceability issues with Tan.

In the dishwasher of the modern type heater installed in the same block as the recirculation pump and its replacement is required to perform assembly.

The sensor temperature control

The temperature sensor generates a command for the heater. Its failure is automatically disables the heating element, which stops water heating. As a result, the fluid does not reach the desired temperature, dishwasher dries the dishes. Method of access to the sensor and the test described above, replacing is performed separately from the pumping and heating unit. To this end, contacts are released and attachment. On the failed node position establishes a new, original.

control module

The module itself is not repaired, in case of failure it is usually changed to a new one. But in the absence of drying a high probability of failure mode switching switch, which is mounted on the board. In the absence of the corresponding signal does not switch the machine for drying, resulting in the output tableware wet.

For the self-exchange module need a soldering iron and basic skills in electronics. If no such experience, it is better not to do it and entrust the repair specialist.

Repair fan

A similar situation with a hot air blower. Element is not repaired, changed entirely, but to replace it is necessary to spend time on the dismantling of the dishwasher. To do so without professional skills is quite difficult and time consuming. If, despite everything, decided to perform a self repair is necessary:

  • carefully read the instruction;
  • to pinpoint the location of the fan (in different machines in different ways);
  • disconnect the power supply;
  • remove the protective wall is usually the side;
  • Using a multimeter, check for resistance;
  • visual inspection to ensure presence / absence of mechanical damage;
  • if it does not remove the faulty fan and install a new one.

Most of these faults is not recommended to remove yourself, especially in the absence of knowledge and experience. Despite the additional cost of repair is the best option of inviting a specialist service center.
