A device for washing plates from Bosch greatly simplifies the worries of every housewife. If you compare the amount of water consumed when washing dishes by hand and using dishwashing equipment, the conclusions will be in favor of a useful invention, the cost of purchasing which will pay off quickly enough. It should be noted that the functionality of the dishwasher depends on many factors, including valves. If one of them malfunctions, the machine stops performing its duties or allows interruptions in work. Let's try to figure out which valves the manufacturer uses for a Bosch dishwasher.
Kinds
The purpose of any similar device in a Bosch dishwasher is to pass a certain volume of water in the direction necessary for the operation of the machine, and timely block the paths for its intake.
The valves are electromagnetic and operate under the control of a modular device. Command signals are sent from it, after which the valves begin to open or close.
Let's look at which valves are installed in a Bosch dishwasher:
- inlet solenoid valve responsible for water supply;
- reverse, working to drain liquid;
- a special Aquastop valve that protects against possible leaks.
Each of them has different device features, mounted at certain points, changes according to a specific algorithm of actions.
Inlet valve
He has an important role to play. The water supply valve stops the flow of liquid into the dishwasher chamber. Its main purpose is to open after a signal from the control module for a certain time so that the required amount of water enters the dishwasher, and then close the entrance again upon an additional command.
The fill valve is activated when the dishwasher requires a supply of clean water. Depending on the dishwashing program used, this element can operate from two to eight times in one cycle.
The existing connection between the inlet point and the dishwasher control module allows you to quickly interrupt the liquid supply not only during normal operating mode, but also in the event of an emergency. It should be noted here that for emergencies, the Bosch dishwasher is equipped with a special device.
Drain valve
The anti-siphon element (reverse) is designed much simpler, but its role in the overall system does not decrease due to this. This part is installed at the base of the dishwasher drain hose. When the pump, under the created pressure, begins to pump out waste liquid into the sewer pipe, this element is activated to open and lets dirty water into the drain. As soon as the pump stops, the part reliably closes the outlet.
Some consumers who installed their own dishwashers, ignored the installation of this element, and later bitterly regretted their actions. From the blockages that formed in the sewer pipe, all the dirt returned to the washing mashine and settled on clean plates.
Protection against possible leaks
It is part of the Aquastop system. Some users think that such an element is the only example of protection, but this is a mistaken opinion.
Bosch machines are partially protected from leakage; there is a special float sensor in the pan. As soon as a sufficient amount of liquid accumulates, the float floats up and closes the sensor contacts, from which a command signal is sent for instant closure.
In order for the valve to return to the open position, it is necessary to open the contacts, to do this, drain the water and eliminate the cause of the leak in the dishwasher.
Aqua-stop element built into the inlet hose dishwasher Bosch, completely protected from leakage, is activated by the rupture of the sleeve, which has a double layer.
As soon as the main layer ruptures from the water pressure, the liquid trapped between the layers presses on the valve. The element closes tightly, stopping the flow of liquid into the machine. Any actions to restart will not be successful. In this case, it is necessary to completely change the hose, because the entire system is designed on a one-time use basis.
Substitution rules
When changing the water intake valve, you should not make mistakes in connecting its contacts. To work, you will have to remove the tray from the dishwasher.The part is directly connected to the water intake hose, and it is quite easy to find it. Before dismantling the old element, it is recommended to take several photographs to avoid mistakes during assembly.
The part responsible for draining waste liquid from the dishwasher requires complete replacement if it is severely clogged. As a rule, this happens five to seven years from the date of operation of the Bosch dishwasher. The old element is unscrewed, a new analogue is installed in its place - there is nothing complicated in such work. This valve is made of high-quality plastic material, does not emit harmful toxins, and can be purchased at any store that sells plumbing fixtures.
The easiest way to replace the valve is located in Aqua-stop dishwasher system. In this case, there is no need to disassemble the machine to wash plates - the element is located on the outer part of the body. There is only one unpleasant feature - the cost of the new analogue reaches forty-five US dollars. And over the entire period of operation of the machine, which is seven to twelve years, such a malfunction occurs at least two to three times. Repairing a dishwasher is expensive, but without this measure there is a risk of flooding on the floor below.
Conclusion
As a conclusion, it should be noted that a dishwasher from Bosch has the optimal number of valves, each of which performs its own functions in the overall performance of the unit.It is with their help that household appliances work smoothly, helping to deal with mountains of dirty dishes every day.
