Device device

Before you figure out why there are problems with water in the Bosch dishwasher, you need to study how this appliance works. You should immediately pay attention to the fact that the design of the device is not simple. The manufacturer recommends that you perform only a few actions yourself: cleaning the filters from contamination and additional settings. In other cases, it is recommended that you contact the service center with all problems. But if the owner of the dishwasher has certain knowledge, then you can try to do the repair yourself. To do this, you need to know by what principle the device works. For one dishwashing cycle, several actions are performed:

  • Preliminary and main washing.
  • Rinse.
  • Drying.

In order for the device to work, it must be connected to the mains. After this, water is drawn. This action is performed automatically. Water passes through a special salt softener in order to prevent the formation of scale. Then it penetrates into the machine under pressure through the inlet valve. The amount of water is adjusted using a special float. There is also a pressure switch in the dishwasher. It is designed to turn off the water pressure when its level reaches its maximum mark. Only after this begins heating and the dishwashing itself.

Bosch dishwasher does not collect water: reasons

Before you figure out the reasons why malfunctions with water intake occur, it should be noted that the German company produces devices of rather high quality. As a rule, they break very rarely, but this cannot completely exclude damage. No one is safe from this. Let's look at the main reasons why the Bosch dishwasher does not pick up water.

  • The water supply tap to the device is closed.
  • There is no pressure in the central water supply.
  • The hose through which water enters the machine is pinched.
  • The water level sensor is out of order.
  • Malfunction of the intake solenoid valve. Most often due to power surges.
  • The door lock has broken, or it is not tightly closed.
  • The strainer is clogged.
  • A leak occurred, so the Aquacontrol system blocked the flow of water to the device.
  • Faulty control module.

Please note that the first two points do not pose a danger to the device. Naturally, you do not need to carry out expensive repairs. In the first case, the dishwasher will start working as soon as water appears in the water supply. In the second - before turning on the device, it is necessary to double-check whether the water supply tap is open. These reasons can be called commonplace, and they arise only by the carelessness of the owners themselves. Next, we consider serious damage to dishwashers.

Caution - module breakdown!

In no case can you repair your Bosch dishwasher yourself if the control module fails in the appliance. This problem is rare, but it is the most serious. It is because of a malfunction in the electronics that the machine does not pick up water.

In this case, you will need to remove the module and test it in the laboratory. Sometimes experts reflash it. If this does not produce any results, then you will need to install a new one.

Qualified employees of service centers strongly recommend that in the event of a breakdown not to diagnose the control module on their own, as this can lead to its final failure. Professionals will cope with this much faster and better. In the end result, although you will have to pay for the repair, a guarantee for the work will be provided.

Loading door

If the Bosch dishwasher is not collecting water, you must check that the loading door is closed properly. The fact is that the design of the device is arranged in a certain way - until the lock is turned on, the washing cycle does not begin.

There are several reasons for this problem.

  • The first is simple. It lies in the fact that the owner just loosely closed the door. Sometimes containers or baskets may not be installed correctly. They do not allow to close the door.
  • The second is more serious. It occurs due to a broken castle. In this case, only repair or replacement of the part with a new one will help.
  • The third reason, because of which water may not accumulate, is that the appliance is not set at the level. Because of this, a slight deformation occurs, which does not allow to close the door.
  • And the last reason is damage to the sealing gum. It is worth noting that even the slightest deformation of it can affect the loose closing of the door.

If the Bosch dishwasher is not collecting water due to a broken door lock, you can replace it yourself. To do this, you will need to buy a new part. Installation is quite simple:

  • Opening the door, you need to unscrew the mount.
  • Remove terminal with connected wires.
  • Unscrew the screws that secure the lock.
  • Fasten a new one and connect the terminal.
  • Install the top panel of the door and tighten the self-tapping screws.

When replacing an old lock with a new one, do not forget about the latch.

Filter cleaning

The most common reason a Bosch dishwasher is not collecting water is because the filter is dirty. This part consists of a special fine mesh, thanks to which debris does not enter the machine. Hard water can cause filter contamination. It is the scum in most cases that is the reason why the device starts to malfunction.

It is not difficult to clean the filter; each owner can perform these actions. To do this, you need to turn off the water intake valve and remove the inlet hose. There is a small filter at the mounting point. It is taken out and washed under running water. If there is a lot of scale, then it is advisable to immerse the filter in boiling water for half an hour with the addition of citric acid or vinegar. After cleaning, all parts are set in place.

Inlet valve

Another reason that the Bosch dishwasher is not collecting water may be the inlet valve malfunction. It is this part that allows access to the fluid inlet to the inlet hose. Failures occur due to power surges.

It is not possible to repair the inlet valve, therefore it is only necessary to install a new one. A part is selected depending on the make and number of a specific model of the machine. If the owner has certain knowledge, then you can replace the inlet valve yourself without contacting a service center.

Water level sensor

If the Bosch dishwasher does not pick up water, and all the lights are on and the sound of the electric motor is heard, then the pressure switch could fail. It is this element that determines how much fluid is collected in the tank of the device. If the water level sensor does not work correctly, then the following failures occur:

  • Water actually enters the machine, but the control module does not fix this.
  • The tank of the device overflows with water, so the pump starts to work in emergency mode, pumping out all the incoming water.
  • A failure in the electronics leads to the fact that the module, without detecting the presence of water, blocks the washing cycle, respectively, stops the machine completely.

In order to make sure that the water level sensor is broken, you need to listen if there is water in the device. If it is present, and the control module gives an error, then you will have to change the pressure switch. You can do this yourself, having certain knowledge, or you can turn to professionals for help.

Water is taken, but the washing mode does not start

If the Bosch dishwasher draws a little water and stops, the cause may be a problem with the engine. This part is the main one in the device. It is she who ensures operability. Having listened to the device and heard a characteristic sound, we can assume that it simply jammed the pump or engine. For accurate diagnosis, a special multimeter is used. It can also be used to determine winding breakage. It is best to contact a service center with engine malfunction. They will either offer repairs or replace with a new one.

No water supply

If there is no water supply in the device, and the pressure in the central water supply is normal, then there is definitely a problem with the dishwasher itself. This malfunction can occur if there was a short circuit in the network. It leads to a malfunction of the electronics, a malfunction of the motor, in particular to a short or break of the windings. In both the first and second cases, it is better to contact a service center to conduct a complete diagnosis and find out the reasons why water intake is not taking place.

Conclusion

This article explained why the Bosch dishwasher does not draw water. There are many reasons for this. They are all different: from simple trivial (forgot to open the feed tap) to a malfunction of the electric motor. Owners should understand that not all breakdowns can be fixed with your own hands.

Sometimes self-diagnosis can only do harm. This should be understood by those who want to save on the services of professional masters. For example, problems with the control module can lead to a complete failure of the dishwasher. Naturally, this will lead to higher costs than will be spent on repairs in the service center. Therefore, it is recommended to first exclude such reasons as lack of water in the central water supply, pollution of the filter, bending of the intake hose, and only if this did not help to solve the problem, contact professionals immediately. They will quickly find a malfunction, replace a failed part and give a guarantee for their work.
