In the maintenance process of the washing machine, the failure of the pulsator, or the slow rotation, or the failure of the reversal can be said to be quite a lot. The failure in this aspect is simple and simple, and it is difficult and difficult to say. Xiao Bian has sorted out a few tricks on the Internet. If the washing machine in your home has the above situation, you may wish to try it.
The reasons for the non-rotation or weakness of the pulsator are as follows: the V-belt is too loose or falling off; the capacity of the motor capacitor is reduced or invalid; the motor itself is faulty; the program controller has no signal output.
The pulsator does not rotate when washing
After starting the machine, it can automatically enter the water, indicating that the washing machine is working. After the predetermined water level is reached, the water inlet can be stopped, indicating that the water level detection switch is normal. When the pulsator is turned by hand to rotate clockwise and counterclockwise, the pulsator cannot be rotated. When the pulsator is disassembled and inspected, it is found that the planetary gear inside the clutch is stuck due to damage. After the clutch is replaced, the fault is eliminated.
The pulsator does not change direction when washing
When the washing machine is in reverse washing, the clothes in the bucket can only be rotated in one direction, and the program control indication on the upper side has no stepping index, and the buzzing sound of the stepping jump position of the electrical contacts in the device is not heard. Check the micro-motor. The DC internal resistance measured by the multimeter R×1k is 20kΩ and 24kΩ respectively, indicating that the micromotor winding is not damaged. Then use two fingers to pinch the pinion clockwise, and the pinion does not rotate smoothly. It was found that the permanent magnet rotor of the micro-motor was broken by 2 pieces, and the crack was firmly fixed with the universal glue, and the trouble was eliminated.
Washing does not work after booting
When the washing does not work after starting, you should first unplug the power supply, and then check: whether the power is off; whether the grid voltage is too low, use a multimeter to measure 250 volts, if the voltage is below 187 volts, the washing machine may not run; Whether the plug and the socket are in poor contact; if the power fuse is blown, if it is blown, the electrical circuit should be checked. If there is no problem, the fuse can be replaced after use; if the wiring is loose, or there is a phenomenon of soldering or de-soldering.
Maintenance method
After troubleshooting the above causes, you can follow the steps below. Whether the V-belt is detached or worn for a long time, worn and elongated; whether the washing motor is stuck due to bearing wear; whether the washing motor is short-circuited or broken; whether the capacitor is damaged or the lead is detached; whether the washing timer is faulty; The switch should check whether it is normal or the lead is broken; whether the pulsator is stuck by foreign matter, or the spindle component is stuck due to wear, lack of oil, and gear of the reducer due to excessive use time. For the above various causes of failure, take the corresponding measures to solve.
