If your dishwasher is not picking up water, it is very possible that the problem can be solved. So, first of all, check:
Water in the tap. Maybe you did not notice the announcement on the entrance door about preventive maintenance? Check the taps in the house to make sure there are no problems with the water supply.
The door is not closed properly. If the dishwasher door has not been closed completely (no characteristic click is heard), the washing process will not start.
Water supply valve. A special shut-off valve is installed on the system for connecting the dishwasher to the water supply system, shutting off the water supply. This is for safety and also so that there is no constant pressure on the intake valve. The valve is usually located on the water pipe to which the dishwasher is connected. Just open it and the machine is ready to go.
Hose through which water enters the dishwasher. If there is water and the stopcock is open, it's time to check the hose. It can be pinched, and, accordingly, the water supply to the "dishwasher" is blocked. Make sure the hose is not seriously kinked or heavy objects are lying on it. If this was the problem - try again to start your "assistant".
But what to do if you performed all these tricky manipulations, made sure that there is water in the tap, and everything is in order with the hose, but the dishwasher is still not receiving water? It means that some kind of malfunction has occurred. Therefore, disconnect the equipment from the power supply and try to determine the type of failure using the table below.
The dishwasher door is equipped with a locking device. It is essential for user safety and protection against leaks. If this device fails, the machine does not start the wash cycle and, accordingly, does not draw water. The dishwasher door lock must be replaced.
All dishwashers are equipped with a water supply valve. When the equipment starts to work, the signal is sent to the valve, which, in turn, opens, and water begins to pour into the machine. Due to voltage surges or wear, the valve may "burn out". The water supply valve needs to be replaced.
A pressure switch is a special sensor that measures the water pressure and transmits information to the control unit, which, in turn, analyzes how much water is needed for each wash cycle. If the pressure switch fails, the signal is not sent to the control module and the dishwasher does not draw water. Replacement of the water pressure sensor is required.
Dishwashers are equipped with an "intelligent" control module that sends program commands to other parts of the unit, for example, "draw water" in the inlet valve or "drain water" of the drain pump. If a malfunction occurs in this device, the machine stops working or does it incorrectly. Requires a "flashing" of the module or its complete replacement.
Modern units are equipped with the Aquastop leakage protection system (AQUASTOP). If the "dishwasher" with this technology suddenly stops working, there can be two problems: either a leak happened and Aquastop blocked the water supply, or the system itself failed. In case of a malfunction in Aqupastop, the system must be repaired or completely replaced.
Even though most breakdowns in dishwashers are quite typical, sometimes there are malfunctions that are difficult to diagnose by any additional signs. Taking into account the manufacturability of modern technology, it is not recommended to try to fix the dishwasher on your own - amateur performance is unlikely to give a positive result, but sending your "assistant" to the trash can easily. The most reasonable way out in this situation is to entrust the repair work to professionals. If you need help with home dishwasher repair, call us right now!
