Zanussi ZWS185W washing machine does not draw water: causes and troubleshooting

Machine Zanussi ZWS185W. When the start button is turned on, nothing happens, it just lights up, then it starts flashing. But it does not fill with water. And when we unscrew the hose, then there is water, but it does not flow.

Good afternoon, Vlad.

The problem you described occurs for several reasons:

1. Clogged pre-filter installed at the entrance to the washing machine. In order to access it, disconnect the flexible eyeliner from the nozzle located on the rear wall of the household unit. After that, pry the filter element with a flat-blade screwdriver and take it out. You should act carefully, however, you should not be afraid of damaging anything - the filter is made of durable plastic and has a tide with a hole on its body, which is designed specifically to simplify dismantling. Thoroughly clean the filter element and rinse thoroughly under pressure. After that, reinstall the part and connect the hose - the water supply to the washing machine should resume.
2. If the filter cleaning procedure does not work (or it was originally clean), make sure that the solenoid valve is working. Finding it will not be difficult - usually the water supply pipe (the one in which the coarse filter is installed) is part of its body. The first thing you need to do to check the operation of the valve is to measure whether current flows through its solenoid after turning on the washing mode. You can do this with a multimeter by setting its switch to voltage measurement mode. Power parameters are indicated on the solenoid valve body - most often 220 volts are required for its operation. If everything is normal with voltage, then this indicates a coil malfunction - the device will have to be replaced.
3. If the voltage on the solenoid valve does not appear when the washing machine starts up, this indicates a malfunction of the control module. Perhaps the problem is a failure in the firmware of the command device or the failure of the power unit that commutes the electromagnetic valve. In addition, the reason for the lack of power on the shutoff solenoid may be sticking of the contacts of the water level sensor (pressure switch). In this case, the control module does not supply voltage for the simple reason that the pressure switch indicates the presence of a full water tank. It is not difficult to check the pressure sensor - it is enough to disconnect the tube from the tank and blow into it, while measuring the position of the contacts at its outlet. In one position, they should be closed, and in the other show infinitely large resistance. If necessary, the pressure switch should be replaced.

I must say that anyone can clean the filter, as well as check the water supply valve and the pressure switch, for this basic knowledge and skills are enough.As for the control unit, it is better to entrust its repair to a specialist - the price of a new command device is quite high and sometimes reaches half the cost of a used washing machine.
