How to replace brushes in a washing machine
With prolonged use, the washing machine becomes unusable. However, some breakdowns can be detected in advance, as they warn about themselves in various ways.
Consider a frequently encountered malfunction, in which hundreds of customers turn to repair a washing machine in Coimbatore every month. That is the lack of rotation of the drum.
Motor brush: symptoms of failure and replacement cost
During the washing process, the machine may make an atypical crackle. Most of all, it is heard during the spin cycle, when the maximum speed of rotation of the drum is reached. Occasionally, in addition to additional extraneous noise, an unpleasant smell of burnt rubber or plastic may appear. An indicator of the failure of the motor brush can also be the top of the drum and the entire operation of the washing machine, which is not related to the power supply and surges. You can also pay attention directly to the quality of spinning clothes; if it is bad enough, we can conclude that the engine power is reduced.
One of the factors which can determine breakdown can be a program failure with the corresponding error code on the electronic scoreboard. All these factors usually indicate that the motor brush needs to be changed. It is necessary to replace it since this part of the washing machine cannot be repaired. The price of replacing brushes in a washing machine starts from 2500 Rupees. The cost is affected by the company of the washing machine and its modification.
The importance of the motor brush and its types
The motor brush performs one of the fundamental functions and, in fact, allows the washing machine to carry out its primary work. With its help, electrical energy is supplied from the outside to the engine. It is his launch that is the beginning of the entire washing program. These parts are composed of a spring, a cube or cylinder tip and a carbon contact.
Motor brushes are of three types:
- Carbon-graphite.
- Copper-graphite.
- Electrographite.
A mixture of graphite or carbon powder and copper filler is used in most cases. The part is made under a high-pressure press, is highly durable, and lasts almost as long as the washing machine. However, even such stable things can occasionally become unusable.
The procedure for replacing brushes on the engine.
Replacing motor brushes is a complex and time-consuming process. Repair requires the necessary knowledge and understanding of the principle of operation and design of the washing machine. Therefore, it is required to seek help from repair services and leave the work to specialists.
The process itself is carried out, of course, only after turning off the washing machine from the power supply. Next, you need access to the back wall. After twisting the service hatch, access to the engine and other internal parts are opened. Next, you need to remove the machine itself. That is done in the following way:
- It is freed from various belts and wires.
- Fasteners are twisted with a unique key.
- Disconnect all excess wiring, after which the engine is directly removed.
The critical point is that the brushes on the motors must have the same wear, respectively, and should change both simultaneously. As a rule, an original part corresponding to the original one is selected. However, there are also universal options suitable for many models and brands of washing machines.
The old spare part is removed from the brush holders and carefully replaced with a new one. After this procedure, the engine and all components return to their original place, all bolts are screwed on, and the wires are attached. After installation, the quality and correctness of the replacement, belt tension, etc., are checked. First, the drum is scrolled by hand and checked for interference and noise. If the process goes without interruption, the repair is considered complete, and the washing machine is ready for operation.
