Prolonged use dishwashers situation may arise when the dishwasher is not draining after cleaning. The problem may be more than one. But before moving on to their definition, you must ensure you have the typical signs of breakage.
Of course, the main evidence of the lack of normal operation is the remaining water in the washing compartment. But in the dishwasher under the brand Bosch its existence can only be determined after the completion of the work. Here the liquid is used in a closed loop through the filtration system, the pump starts to pump at the end of its cycle.
Ensure problems can be visual inspection, after the cessation of work by opening the wash bay. Other models which drain occurs periodically, can stop work without completing the cleaning. In addition to the residual liquid, the fault indication may be audible and visual indication. On machines with no display is activated indicator light and audible alarm if the display is present, it appears appropriate error code.
| The car | Error code |
|---|---|
| Bosch | E24 |
| Ariston | TO 03 |
| Electrolux | I20 |
| Candy | E20 |
| Indezit | TO 06 |
| Eyelid | H5 |
Causes of failure
The whole set of reasons why the machine has ceased to pour the water can be divided into two categories. The first is the circumstances associated with the installation and operating errors. The second group consists of the reasons that caused by technical defects.
installation and operation errors
In most cases, defects due to which the dishwasher does not drain associated with usage rules neglect and care for self installation errors. In this case, even a new device refuses to function properly. The main reasons are as follows:
- Incorrect installation of the drain hose;
- filter clogging garbage;
- blockage of other sites runoff.
Laying the discharge hose
This is the simplest and legkoustranimaya reason, you want to check in the first place. For normal operation of the hose must have two loops in the connection to the device before connecting pipe and siphon. In this case, the excesses are not allowed. Their presence blocks the flow, and the absence of loops may cause siphoning. In both cases, the pump is unable to pump out the water, which leads to its accumulation in the tank. Restore operation can be yourself. Would need:
- turn off the power;
- shift the hose in accordance with the requirements of the instructions;
- start the device again.
Clogging junk filter
If the fluid is still refusing to flow in the normal mode is probably the cause of the defect is hidden in the debris filter. It is a set of mesh plates and glasses, which are screwed into the floor compartment detergent.
food debris can gradually clog the filter cell. For cleaning all the elements necessary to dismantle and rinse under running water.
To this end need:
- remove the basket;
- unscrewing the filter bowl;
- remove the cage plate;
- wash them with detergent and a brush;
- check rocker sprinkler to clog, also cleaned if necessary;
- install a filter in the reverse order.
Contamination of other sites
Clean the filter does not always provide a positive result. In this case, the plug should look at other elements of the drainage system. If the water after disconnecting the hose from the siphon descends freely, the tube located at the entry to sewers and eliminating the cleaning of the ordinary. Much more trouble will cause clogging of the drain pump. To clean it is necessary, first of all, decide how it is more convenient to drain the accumulated water from a broken dishwasher. Its gravity can be lowered by tilting the device sideways, or scoop out the liquid by hand. Then:
- remove the inlet hose;
- put the machine on its side;
- unscrew the tray;
- remove the level sensor;
- remove the pump by releasing the fastening and contacts;
- clean impeller and volute;
- stripping contacts check resistance (rate of 200 ohms);
- pump check valve for clogging, if any.
technical issues
When all attempts to fix the problem have not been successful, the reasons for failure must be sought in the failure of the node and device units. Despite the reliability of the dishwashers, it is the result of normal wear and tear or external factors. Water can not go down the drain as a result of:
- pump failure;
- malfunction of the water level sensor;
- leaving the system control board.
Damage to the pump
Contamination is not the only possible defect of the pump. With long-term and heavy use of machines his working life may come to naught. Possible damage to the impeller due to ingress of solid objects (fragments of dishes). The device can burn during surges. If the resistance verification voltage to the control board is not present, non-operating item and must be replaced.
sensor fault
The level sensor must be triggered during the filling of the pallet. When the defect signal does not pass or distorted. As a result, the pump will not turn on time. Before replacing, make sure it is working. For this:
- dismantle the pallet according to the scheme described above;
- remove the sensor;
- check it to a mouse, by blowing tube;
- We measure the voltage multimeter.
Absence of the click reaction and arrows on a scale multimeter is a sure sign of failure and the need for replacement.
control module
This is a costly construction element which provides a sequence of switching modes. He may suffer from a fault, natural wear, manufacturing defects. In this case, the module will cease to generate the necessary signals in a predetermined sequence, the machine becomes inoperable.
Getting to repair, it should be remembered, rewrite or replacement card is a complex process, self-fulfillment of which is not always possible.
In the event of breakdown and looking for an answer to the question of what to do, you need to correctly assess the complexity of the problem. If problems with clogging up can be eliminated by the hands, the most technical failures require a professional approach. In this case, can not do without the participation of specialists.
