If the washing machine suddenly stopped during operation and there is water in it, then we can assume that the pump (drain pump) is out of order. For a machine, this is a standard breakdown that occurs depending on the service life of the unit and the frequency of use of the entire device.
The average pump life is 3 to 7 years. It happens that the pumps can break even a couple of months after buying a washing machine. The reason for this may be inattention, due to which foreign objects get into the drum along with clothes or linen. There is a small gap between the sealing lip of the hatch door and the drum, through which unnecessary items can enter the tank cavity and then into the pump.
After some time, they block the impeller and disable the pumps for washing machines. Sometimes, due to a short circuit in the winding, the electronic control module may burn out at the same time, and the result of this is that repair becomes very expensive. However, more often it is enough just to replace the impeller pump, and your machine will be ready for further work.
The pump for the washing machine has two main components: a motor with an impeller and a snail with a filter. The last element is a plastic pipe with two branches. On the one hand, it has a seat for the engine, and on the other, a recess for the filter cover. During normal operation, the snail practically does not wear out. More often replace the impeller motor .
Older models use a pump for a washing machine with two impellers. One of them cools the engine, the second is designed to circulate water. A feature of older devices is the presence of an oil seal, which prevents the flow of water into the motor from the cochlea.
A modern pump for a washing machine (Bosch, Samsung, etc.) has only one impeller, which performs the main function. There are no glands in the new devices, since the electric part of the pump is structurally separated from the mechanical.
Automatic machines use more than 50 varieties of devices for pumping and draining water. However, they are all divided into several types according to the method of attaching the engine to the cochlea. Some pumps are held on by three screws, although they have five mounting holes (for example, Samsung washing machines, in which a cover is additionally attached).
In addition to the mounting method, the pump for the washing machine of various models can have a different arrangement of terminals, which are located in the front and rear parts of the device, are present together in a common connector or separately. Well, of course, the pumps vary in brand. Specialists engaged in the repair of household appliances, among the best, distinguish pumps of Italian manufacturers, which are famous for their quality (Askoll, Plaset, Copreci). Distribution was also received by Chinese pumps Artiko, Mainox, Aspul, Ecoline.
Many devices can replace each other. When installing the pump in the washing machine, the main task is to select the motor according to the footprint. You can mount pumps with different terminal arrangements. However, it is important to ensure the reliability of the electrical contact.
