What is Electrolux washing machine door switch? Structure and working principle

Using Electrolux washing machine for a long time, but you do not know what the Electrolux washing machine door switch is, as well as its structure and operating principle. This article will answer your questions, check it out!

What is the function of the Electrolux washing machine door switch?

The Electrolux washing machine switch is installed on the front door, which is responsible for closing the door latch when the machine is operating, avoiding the case of children trying to open the door when the machine is washing, thereby ensuring absolute safety for children. your family.

In particular, the washing machine only works and starts the washing program when the door is tightly closed. Therefore, if the Electrolux washing machine refuses to open the door while it is in operation, you should not try to open it, as it will break the lock latch and the door handle of the washing machine.

Structure of Electrolux washing machine door switch

The components that make up the washing machine door switch will be coordinated smoothly, helping the switch to maximize its use. The Electrolux washing machine door switch includes the following parts:

• Locking latch: Responsible for keeping the door tight when the door is closed
• Power closing switch
• Thermistor: Used to heat metal rods
• Thermistor in series with the coil of the relay
• Suction relay
• Steel core
• Metal rod: When heated, the system circuit will be closed and active
• Wheel: Rotating action, responsible for pulling and releasing the brake pin

How does the Electrolux washing machine door switch work?

The Electrolux washing machine door switch, also known as the Electrolux washing machine door lock, works on the principle of thermal expansion. The switch is designed as a fully automatic electric lock, which is responsible for seamlessly connecting electricity when you close the door or lid.

Specifically, when you press the Start button, electricity is supplied to the thermistor in series with the coil of the relay to help heat the metal rod. Once the metal rod has been heated, it will begin to expand and warp to connect with the rest of the washer’s systems to form a closed system.

When the wash is finished, the microprocessor closes the relay inside the door switch. At this time, the iron core inside the coil of the relay will move, causing the inner wheel to rotate clockwise, causing the brake pin to be pulled down. You can then open the washing machine door.

Some signs when the Electrolux washing machine switch has a problem

When you use the washing machine for a long time, there is a risk that the Electrolux washing machine switch will fail, making the switch inoperable. Here are some reasons to help you identify a problem with the washing machine switch, specifically as follows:

• Display error code E40: With a washing machine with LED screen, when pressing the Start/Pause button to start the washing program, the light will blink continuously, the machine will not work and error E40 will be displayed on the screen.
• The Start/Pause light shows 4 red and 1 green : With the washing machine without LED screen, you need to rely on the number of blinks and the color of the Start/Pause light. If the machine flashes 4 times the red light and 1 time the green light, the machine stops working.
• Door Lock light does not light : Door Lock light shows the operating status of the machine, if the light is not on, it means the machine cannot work.
• The door cannot be opened when the washing is finished: The reason is that the door lock is broken, so you have to open it and have to remove it from the inside of the machine to be able to open it.
• The washing machine does not supply water: This error may arise from work The water valve is broken, is locked or the water supply is weak. You need to check the water shut off valve and water supply.
