Life time
So, for the manufacture of electrolates, which equipped with washing machines, choose only very durable materials with good wear resistance. But, meanwhile, the electric motor brushes are considered "consumables" - details that are subject to quite frequent replacement. Why is it going on?
According to the repair of household appliances manufacturers, on average, electric boosters are able to stop 5 years, and with rarely used washed - twicear than. It is quite true: brushes regularly serve for several years, and then burn out and need to be replaced. Thus, they protect other parts of the electric motor from wear, the repair of which will be more time consuming and will cost more.
When should I change brushes?
The fact that the service life of the electric grinder came to an end, and you need to replace the data of the elements, signals the following signs:
- a sudden stop of the engine of the washing machine, not associated with voltage drops and the disconnection of electricity;

Tips for choosing
- Specialists recommend replacing the "native" electrolates only on the original (that is, from the same manufacturer, and intended directly for this model of the washer). There are also universal options on sale, but they can cause engine malfunctions.
- Even if only one brush has become unusable, it is necessary to replace both, since otherwise the load on the rotor will be distributed unevenly, which will lead to new faults.
- Before buying stacks for replacement, determine which variety of brushes was installed in your washing machine. Here there may be three options: brushes in a solid body of plastic, collapsible brushes consisting of three elements or simple brushes, which are rods from graphite with copper contacts.
