A wide range of household appliances has firmly established itself in our homes, and nowadays many homemakers cannot imagine their kitchen without quiet, automated assistants. Despite the reliability of Bosch appliances, there are still instances where unfortunate malfunctions occur, such as when the dishwasher fails to fill with water.
Possible causes
- The domestic water supply does not have any water.
- There is a blockage in the water supply tap to the machine.
- The filler hose is either pinched or bent.
- The Aquastop or Aqua-Control system has detected a leak and has blocked the water intake.
- The water inlet solenoid valve has failed due to fluctuations in the mains voltage – urgent replacement is necessary.
- The loading door is not closed securely or the locking system is faulty.
- The water level sensor in the tank is damaged and provides incorrect information to the control module, resulting in the interruption of water filling.
- The inlet valve strainer is clogged – this issue can be resolved quickly by disassembling and rinsing.
- A malfunctioning Bosch control module is the most severe problem and should be replaced immediately.
If you value your assistant’s well-being, it would be unwise to attempt troubleshooting the broken module yourself – doing so could lead to the need for a replacement unit before the deadline.
If you genuinely care about your assistant, it is advisable to seek the expertise of professionals who can efficiently and reliably resolve the issue.

Let’s understand in detail
If you find yourself without water in your plumbing system, it is important to be vigilant and pay attention to the warnings posted on the bulletin board in your building’s entrance. The Housing and Economic Commission always ensures that residents are informed about any upcoming water shutdowns that may be necessary for maintenance purposes. To troubleshoot the issue, first check if the water supply tap for your dishwasher is open and inspect the condition of the filling hose. Additionally, take a moment to ascertain whether the aquastop mechanism has been triggered or not.
Inlet valve
This specific component is present in all types and models of dishwashing machines. In the event of a defect, the water will not be able to enter the machine’s system, as the valve will fail to open and allow access to the filling hose.
The electric city network experiences fluctuations in voltage, which means that excessive voltage can be sent to the solenoid winding, ultimately causing it to burn out. When the winding is damaged, no signal is sent to the stem, and as a result, the elastic rubber diaphragm remains in place and continues to block the inlet.
Unfortunately, this product is not repairable and must be replaced. If you are unfamiliar with the technical aspects of household appliances, it is advisable to seek the assistance of a professional technician from a service center.
Attention! When replacing the solenoid inlet valve on your own, it is important to ensure that it matches the brand and model number of the dishwasher.
Numerous DIY enthusiasts have been able to successfully complete this replacement without any issues, thereby saving on professional services and preserving their family’s budget.

Loading door
If the machine is not closed tightly, it will not work. To ensure proper closure, press it until you hear a characteristic click. If the water intake does not start after that, the issue may be with the locking system. In such a case, there are a few steps to take:
- Inspect the sealing rubber for any deformation, no matter how insignificant, as it can cause the door to close loosely.
- Check the lock for any faults and replace or repair it if necessary.
- Verify the correct installation of the baskets and garbage cans, as they may interfere with the door closing tightly if installed incorrectly.
- If the machine is not level, the door may not fully close due to interference.
If the reason for the loose closure is the lock, you can replace it yourself. However, you should purchase a new lock specifically for your model in advance. The process of replacing the lock is relatively simple:
- Open the door and unscrew the self-tapping screws. Please be cautious as the edges of the stainless coating on the inside are quite sharp – make sure not to cut your hands. Hold onto the top panel to prevent it from falling out.
- Disconnect the wiring terminal carefully.
- Unscrew the fasteners on the top part and set the lock aside.
- Install the new lock and connect the terminal.
- Insert the top panel into place and screw the fasteners.
The replacement is now complete. Next, you will need to install a new latch to ensure that all components are new. The master in this video provides a detailed explanation on how to do this.
In an attempt to save money, certain DIY enthusiasts opt to fix a faulty lock by replacing the broken plastic components with more resilient stainless steel ones. However, there is no guarantee that such a modified lock will have a longer lifespan than the original factory one, so it begs the question: why bother exerting effort on reinventing the wheel?

Cleaning the filter
Often, the reason why the dishwasher fails to draw water is due to a blockage in the mesh filter. This is especially common when the water is hard and deposits build up, clogging the filter. Fortunately, you can easily fix this issue on your own by following these steps:
- First, close the faucet and disconnect the filler hose from the machine;
- Next, locate the small filter inside at the connection point and remove it. Rinse it thoroughly under running water;
- If the mesh filter is heavily clogged, you can try soaking it in citric acid for about half an hour;
Finally, put everything back in its place and test the dishwasher to see if it can now draw water properly. If it works, congratulations, you’ve successfully completed the repair.

Control module
It is uncommon to encounter problems with the control of all the units and systems, but occasionally, even a trustworthy brand like Bosch may experience issues with drawing water due to electronic malfunctions.
Modern household appliances are highly intelligent and responsive to changes. For instance, the control module signals the pump to initiate the drainage of waste water from the machine tank at the end of the cycle. However, if the drain pump fails to receive the signal due to a malfunction, the machine may either emit a buzzing sound or fail to respond to the Start button. In such cases, it is imperative to seek the assistance of a specialist who will dismantle the module and conduct comprehensive laboratory tests on all parameters. If possible, the module may be reprogrammed, but if not, a replacement will be installed.
Here is an overview of the estimated service fees for the technician from the service center:
| Fault or type of repair | cost of work |
| Replacing the inlet solenoid valve | starting from 900 |
| Replacement or adjustment of the Aquastop system | starting from 1 thousand |
| Problem with the closing of the loading door | starting from 1 thousand |
| Replacing the water level sensor | starting from 1.5 thousand |
| Control module | 2-2.5 thousand |
| Malfunctioning drain pump | 2500 |
| Replacing the heating element | 3500 |
| Engine replacement | 3500 |
In practical situations, we have examined the primary failures that occur. However, even skilled professionals may be unable to promptly and accurately diagnose the issue. Sometimes, it is only after conducting a thorough examination of the device in the center’s specialized laboratory that a diagnosis can be determined.
