Replacing brushes on washing machine engine

A washing machine, like any technical device, is a complex device, the “heart” of which is the power unit. It is he who provides the rotation of the drum, converting electrical current into mechanical movements. Any power unit of asynchronous type has in its structure brushes that often fail.Replacing the brushes of the washing machine engine is not such a complicated process, it can be done independently.

What are they needed for

So, as it became clear, brushes are necessary for normal operation of the electric motor. This is a small but necessary detail, thanks to which the transfer of electrical energy to the rotor winding of the power unit is ensured, due to which, in fact, it rotates.

Brushes are erased with time, so they need to be changed from time to time. And if you tighten with this, then the problem may be much worse and you will have to change the power unit itself.

Varieties of parts

The main difference of all brushes is in their clamping element, which can be:

• mednografitovym;
• carbon-graphite;
• electrographically.

In washing machines are often used exactly coal typeswhich are not so expensive, but reliable enough.

Lifetime

Naturally, it all depends on the type of brushes, brand washing machine, drum load, program intensity and device build quality. Take, for example, the brand Indesit, which has long been famous for its quality: the operational life of its brushes varies from 5-10 years or more.

It should be noted that the failure of the brushes occurs quite rarely.

When to replace

There are several signs that can definitely recognize the abrasion of brushes:

1. Unexpected cessation of operation of an electric power unit, for example, stop during the wash. In the event that this was not accompanied by a power surge or mechanical damage, then the reason is just the same in the wear of the brushes.
2. During washing there was a crackle or other unknown noise.
3. Significant reduction in the power of the electric power unit.
4. The smell of burning wiring and burned from the washing machine.
5. An error code appears on the display.

These are only the most basic causes of abrasion of brushes, but there may be others that only a specialist can recognize.

Replacing brushes will not present difficulties even for those people who have never faced this problem before, but it is necessary to approach the process as responsibly as possible.

Preliminary manipulations with the machine

First need disassemble the washer:

1. Disconnect the device from the mains and water supply / drain system.
2. Remove the rear protective cover.
3. Remove the belt from the pulley.
4. Motor disconnect from power.
5. Remove the engine itself.

It should be understood that the process of disassembly may be somewhat different, based on the specific manufacturer and model of the machine.

Replacement process

The whole replacement process will be shown on the example of the Gorenie brand, but it is actually suitable for other brands:

1. The power unit is laid on its side and the fixing bolts are removed from the brushes, after which the latter are removed.
2. On the other hand, identical manipulations are performed.
3. Having exhausted their working supply, the brushes have a rod length of no more than 1.5 cm (if the length of the brushes is longer, then the problem is not with them).
4. The collector of the power unit is being cleaned.
5. New parts are mounted and fastened with screws.

Attention! Replacement brushes should be carried out in pairs.

Next, you need to put the engine in place and do all other manipulations in the reverse order. Once everything is connected, be sure to check the quality of his work. In the event that it works a little better or even louder, most likely, everything was done correctly. If there is an unpleasant or unusual sound, the problem is most likely not solved.

Attention! The first 10 washes after replacing overload the drum is not recommended.

Conclusion

The brushes of household washing machine engines are easy to replace, so even in service centers such works will be relatively inexpensive. If you are plagued by doubts about their capabilities, it is better to contact the experts. This applies to any cases of washing machine repair: sealing the cuff hatch or repair control module.
