• The principle and maintenance of the door lock of the washing machine

    Washing machine is a very common household appliance in our life, and it is also very helpful to our life. Especially in winter, we rely on washing machine very much. Especially when washing large clothes in winter, washing machine is more important. But many friends find that washing machines will also break down when they are often used. The most common fault is that the door lock of the washing machine is broken. Next, I will share with you the knowledge of washing machine door lock maintenance.

    • 1. If the lock sign appears on the display, it means that the washing machine has been misoperated to set the child lock function during the working process.
    • 2. You need to remember which gear the washing machine was locked when it was working. Just turn the knob to the locked position at that time, and then press and hold the reservation key for 5 seconds to unlock it.
    • 3. If you don't remember where it was locked, you can only try one position by one. For each position, press and hold the reservation key for 5 seconds until it is unlocked. One is to change the micro delay. The other is that there are three wires on the micro delay. If n1n2n3n1 and N3 are connected, N2 can be used without moving, but do not connect it backwards. By the way, the micro delay is simply the door lock. In addition, the door cannot be opened: the water level may not reach the safe level. Therefore, the automatic protection cannot be opened. You can remove the top cover (there are screws at the back). There is a door switch with your hand. Press the plastic buckle of the door with your hand and push it outward to open it. If the problem has not been solved, contact the local maintenance point to replace the door switch.
    • 1. Opening / closing function of main circuit: both ends of the contact switch of the electric door lock are connected in series in the main circuit of the washing machine to control the opening / closing of the electric part of the working device. When the electric door lock switch is powered off, the motor, drainage pump, water inlet valve, etc. of the washing machine cannot work.
    • 2. Safety function: when the washing machine is washing normally, the door cannot be opened to prevent the clothes from being thrown out or the washing water in the cylinder from overflowing, and to prevent accidental touch from causing danger.
    • 3. Time delay switch function: after the washing machine locks procedure is completed, the electric door lock will delay for a period of time after the power is cut off, so as to prevent the door from being opened when the inner cylinder is not stopped stably and the user from being injured.
