In situations where the dishwasher is not taking on water, do not just sin on the unit to malfunction. The causes of failure can be hidden in the improper installation or preparation for inclusion.
These facts can easily be verified independently, without the participation of specialists, and also easily removed.
| Lack of water in the water supply system | The reason can be maintenance work management company. Verified by opening the tap of cold water. If the water supply is no need to wait for completion of the work. |
| Closed stopcock | Usually set at the connection of the inlet hose under the sink. Checked by turning the lamb right. If there is free play, then tap was closed. |
| Gapping door | The machine fails to start when the door is not fully buried. It is necessary to bring it in until it clicks and repeat the attempt to turn. |
| Laying the inlet hose | The source of the refusal may be bends which block the flow. The hose need to shift and allow free flow of water when the unit is switched on. |

technical issues
If these attempts were unsuccessful, the Bosch does not reach the water still have to look for more serious problems. They may be associated with failure of the various components and mechanisms. Some of them can be replaced or repaired by the user, while others require professional intervention.
The most likely and frequent breakdowns include:
- broken door lock;
- Clogged flow filter;
- failure AQUASTOP system;
- breakage of the intake valve;
- feed level sensor fault;
- in the control unit defective.
door lock
To prevent leakage of dishwashers equipped with blocker door. Washing will be activated only after adjusting the door until it clicks, when the signal arrives at the closure of the control board. Its breakage will not allow the pump and accordingly the machine does not fill with water. To eliminate the need to backup failure the lock and screwdrivers. Fault repair simple and can easily be made with his own hands:
- for security reasons you need to disconnect the power supply;
- open the door, unscrew the top rear of the screws;
- remove the front panel, which is mounted inside the lock;
- unscrew the screws, in place of the broken lock to set a new one;
- perform construction assembly in reverse order.
flow filter
At low water quality, abundance of debris in the water before the water inlet hose set flow filter. Neglect of a regular cleaning is clogged and failures in the filling of the tank, where the water does not flow. In this case, the answer to the question of what to do, is obvious, it is necessary to clean the filter. This will require:
- stop the water supply;
- remove the hose, then filter;
- disassemble it, remove dirt;
- rinse with running hot water;
- return everything back on and test the dishwasher operation.
load Aquastop
Modern dishwashers, including German ones, are equipped with AQUASTOP that should prevent leakage. It consists of a valve which in the electromagnetic embodiment supplemented pallet and the float. In the event of leakage of the system blocks the dishwasher and thus does not gain water. If this happens, one way, to eliminate the leakage and replace Bosch inlet hose from the exhaust valve.
Inlet valve
If the unit is turned on, noise, hums circulation pump and trying to pump water, but can not gain, causing the problem may be the inlet valve. This is a sensitive part of the structure, which may suffer from water hammer. For example, a Bosch dishwasher can not cope with such a situation, because it is designed for a valve system pressure not higher than 1 MPa.
In case of breakage valve neremontoprigoden and requires replacement. But do not rush, because the inside of the valve can be dialed dirt. In this case it is enough to clean the device and try to run the sink again.
Supplying water level sensor
Often the problem is the pressure switch, which determines the level of liquid, ringing in the dishwasher. The situation is the same, the machine will beep, dial into the tank thread will make a noise, but the transition is not in the cleaning mode. The reason is that the sensor does not generate the appropriate signal to the control module:
- Water is dialed;
- Overflow alarm mode is activated;
- evacuating pump is switched on;
- Control board provides the display system error code and terminates the operation of the machine.
When self-repair is required to turn the dishwasher, remove the pallet, inspect visually the sensor and check its resistance multimeter.
If there is a fusion of the contacts of the sensor or the absence of voltage is necessary to replace the pressure switch.
Faulty control module
The major part of the PMM construction which distributes control signals to other nodes and components, determines the sequence of operation. At failure of the fee usually do not repair, and changed to a new one. To deal with the problem on their own need:
- fully open the door;
- remove the fixing screws;
- open access to the interior doors;
- examine the cost.
If the damage can not be seen visually, it is better to abandon the self-repair attempts and contact the service center.
Obviously, not all of these faults can be corrected by hand. Even if the cause of failure is well established, you should carefully weigh the possibilities and think about inviting a specialist. Improper intervention often leads to more significant problems and related costs may require purchase of a new appliance.
