In order to make life easier for housewives, manufacturers have developed special dishwashers. Their role cannot be underestimated. This appliance is designed to wash dishes with minimal human intervention. Few people refuse to use it, since the dishwasher saves not only time spent on work, but also energy. However, what to do if the Bosch dishwasher does not draw water? Such a breakdown can greatly spoil the mood of the hostess. Is it possible to fix this problem on my own? What are the reasons for this problem? The answers to these questions will be given within the framework of this article.
Device device
Before you figure out why the Bosch dishwasher has water problems, you need to study how this device works. Immediately it is worth paying attention to the fact that the design of the apparatus is not simple. The manufacturer recommends that you only carry outsome actions: cleaning filters from contamination and additional tuning. In other cases, it is recommended to 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 how the device works. Several actions are performed in one dishwashing cycle:
- Pre-wash and main wash.
- Rinsing.
- Drying.
In order for the device to work, it must be connected to the mains. This is followed by water intake. This action is performed automatically. Water passes through a special s alt softener in order to prevent scale formation. After it, under pressure through the inlet valve, it penetrates into the machine. Adjustment of the amount of water is carried out using a special float. The dishwasher also has a pressure switch. It is designed to turn off the water pressure when its level has reached the maximum mark. Only after that does the heating begin and the dishwashing itself begins.
The Bosch dishwasher does not draw water: reasons
Before you figure out the reasons why malfunctions occur with water intake, it should be noted that the German company produces devices of fairly high quality. As a rule, they break very rarely, but this cannot completely exclude breakdowns. Nobody is immune from this. Let's take a look at the mainreasons why the Bosch dishwasher does not draw water.
- The water supply tap to the device is closed.
- There is no pressure in the central water supply.
- The hose that supplies water to the machine is kinked.
- The water level sensor failed.
- Faulty inlet solenoid valve. Most often occurs due to power surges.
- The lock on the door is broken or not closed properly.
- Strainer clogged.
- There was a leak, 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, it will not be necessary 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 banal, and they arise only due to the carelessness of the owners themselves. Next, consider serious damage to dishwashers.
Caution - module failure
In no case should you repair the Bosch dishwasher with your own hands if the control module has failed in the device. This problem is rare, but it is the most serious. It is due to a malfunction in the electronics that the machine does not draw water.
In this case, you will need to remove the module and test it in the laboratory. Sometimesthe experts are reflashing it. If this does not give 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, do not diagnose the control module yourself, as this can lead to its final failure. Professionals will cope with this much faster and better. In the end, although you will have to pay for the repair, however, a guarantee will be provided for the work.
Loading door
If the Bosch dishwasher does not draw water, you need to check if the loading door is closed tightly. The fact is that the design of the device is arranged in a certain way - until the lock is turned on, the washing cycle will not start.
There are several reasons for this problem.
- The first one is simple. It lies in the fact that the owner simply loosely closed the door. Sometimes containers or baskets may not be installed correctly. They are the ones who keep the door open.
- The second one is more serious. It occurs due to the breakdown of the lock. In this case, only repair or replacement of the part with a new one will help.
- The third reason why water may not be drawn is that the device is not level. This causes a slight deformation that prevents the door from closing.
- And the last reason - 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 dishwasherBosch does not draw water due to a broken door lock, then you can replace it yourself. To do this, you will need to buy a new part. Installation is quite simple:
- Opening the door, unscrew the mount.
- Remove terminal with connected wires.
- Unscrew the screws that secure the lock.
- Fix the new one and connect the terminal.
- Install the top panel of the door and tighten the fastening screws.
When replacing an old lock with a new one, do not forget about the latch.
Cleaning the filter
The most common reason why a Bosch dishwasher won't draw water is that the filter is dirty. This part consists of a special fine mesh, thanks to which debris particles do not enter the machine. Hard water can contaminate the filter. It is scale in most cases that is the reason why the device starts to malfunction.
Cleaning the filter is easy, these actions can be performed by each owner. To do this, turn off the water tap and remove the inlet hose. There is a small filter at the attachment 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 installed in their places.
Inlet valve
Another reason that the Bosch dishwasher does not draw water may be a malfunctioninlet valve. It is this part that opens access for the flow of fluid into the inlet hose. Failures occur due to power surges.
It is impossible to repair the inlet valve, so you only need to install a new one. The part is selected depending on the brand and number of a particular model of the machine. If the owner has certain knowledge, then you can replace the intake valve yourself without contacting a service center.
Water level sensor
If the Bosch dishwasher does not draw 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 liquid 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 detect this.
- The tank of the device is overflowing 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 withdrawn, butwash cycle does not start
If the Bosch dishwasher draws a little water and stops, then the cause may be problems with the engine. This part is the main one in the device. That is what makes it work. Having listened to the device and heard a characteristic sound, it can be assumed that the pump or engine simply jammed. For accurate diagnosis, a special multimeter is used. With it, you can also determine the breakage of the winding. It is best to contact a service center with an engine malfunction. They will offer either repair or replacement with a new one.
No water supply
If there is no water supply in the appliance, and the pressure in the central water supply is normal, then the problem is definitely in the dishwasher itself. This malfunction can occur if there was a short circuit in the network. It leads to a failure of the electronics, a malfunction of the engine, in particular to a short circuit or breakage of the winding turns. 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 is not being taken.
Conclusion
This article explained why the Bosch dishwasher does not draw water. There are many reasons for this. All of them are different: from simple banal ones (they forgot to open the supply valve) to a malfunction of the electric motor. Owners should understand that not all breakdowns can be fixed by hand.
Sometimes self-diagnosis can only hurt. This must be understood by thosewho wants to save on the services of professional craftsmen. For example, problems with the control module can lead to the complete failure of the dishwasher. Naturally, this will lead to more costs than will be spent on repairs in the service center. Therefore, it is recommended that you first eliminate such causes as lack of water in the central water supply, filter contamination, bending of the intake hose, and only if this does not help solve the problem, contact the professionals immediately. They will quickly find the problem, replace the failed part and give a guarantee for their work.
