There are many factors that can lead to damage to the washing machine.Among these manufacturing defects, improper operation, poor tap water, poor quality detergents etc.This problem can occur in different parts of the unit.Some elements of the repair is quite simple, some require professional intervention, but there are parts that in case of failure can not be repaired and needs to be replaced.

Engine - an essential element of the washing machine, without which it simply can not work .Damage to the engine is considered a serious fault, which decided to eliminate the cause of the master.In this article, we will tell you how you can verify the device at home, without calling out an engineer.

Types

The first thing to do before starting the diagnostics - is to determine what type of engine installed in your washing machine.Total there are several types of engines, which manufacturers use to equip stiralok.Provide a

brief summary of them in a table.

  • high efficiency;
  • simple design;
  • convenient location;
  • small size;
  • low noise;
  • no parts need to be replaced
  • complicated wiring;
  • high cost

Means of verification

There are two ways to allow yourself to check serviceability of the washing machine motor.In order to be able to use them, you need to have at least a basic idea of ​​the motor unit and how is its food.On the Internet you can find a variety of schemes that are accessible way reflect this important information.

washing machine motor
  • first method involves checking the voltage supply to the starter motor and the rotor windings, previously alternate combination of these elements.The disadvantage of this method is that it does not guarantee the result of 100%, since even if the motor is energized to rotate, it does not mean that it will function properly for various modes of operation of the washing machine.
  • second method requires special equipment, and it auto-transformer output power of 500 watts.With the help of this instrument should be connected to power the starter and rotor windings.This method is more secure because it allows to control rotational speed.

What should I do?

Broken slats (plate contacts) in

collector
  • check the serviceability of parts by turning the rotor manually: If you hear crackling, breaking takes place;
  • small metal detachment can be avoided if to remove the item and pierced it with sandpaper or a special machine

Interruption in the rotor winding or starter

  • check for wear parts as possible, making sure their work: if the brushspark, and they remain black patina, then you need to replace them

Wear electrobrushes

  • detect open as possible, checked multimeter, translated in the resistance measurement mode (resistance between the slats must be within 0.1-0.4 ohms);
  • if there was a break, the engine would be best to change to the new (or replace that part, in which a fault)

Video tells about how to diagnose engine trouble on their own, without causing the masteron house.

Verification of the washing machine motor
  • If, diagnose the engine, you have come to the conclusion that it is necessary to replace the electric toothbrush, you should not buy the first available option.Experts advise to look for spare parts from the manufacturer, as the brush of another model is likely not suitable for your washing machine.
  • test drive, you need to take care of that as a result he did not check out of order due to power surges.It is recommended to connect an additional circuit element such as a heater or a lamp with a sufficiently high power.
