When purchasing electrical appliances, users are often recommended to connect the grounding wire. Certainly, for those unfamiliar with electricity, the term 'Grounding Wire' is both unfamiliar and familiar. So, what is the function of the 'Grounding Wire,' and why do we need to use it to ensure the safety of our family? 
What is the Grounding Wire?

We often have a vague idea about the concept of a 'Grounding Wire,' but somewhere in our lives, we have used it without even realizing. The Grounding Wire, also known as the earth wire, is a short conductor connecting high-voltage devices like water heaters, washing machines, refrigerators, etc., to the ground.

The Grounding Wire prevents the risk of electrical leakage
Electrical appliances, especially washing machines, air conditioners, refrigerators, water heaters, etc., are often recommended to use the Grounding Wire. Why is that? And why does the seemingly harmless washing machine fall into that category?
Before each type of washing machine is released, the manufacturer carefully calculates and minimizes the risks of electricity, ensuring safety for users. However, during operation, water and soap bubbles can overflow, causing the electric motors and circuits inside the washing machine to become moist, leading to electrical leakage.
Moreover, the washing machine's metal casing is designed to be conductive, so if electrical leakage occurs, it will be transmitted outside the casing. Users accidentally touching it can result in unexpected electrical accidents.

Electrical shock hazards often occur unexpectedly, so preventive measures and protection are necessary. Connecting the Grounding Wire for washing machines is a simple yet effective safety measure. After the washing machine is grounded, if electrical leakage occurs, it is safely transmitted to the ground and does not harm the user. 
How to connect the Grounding Wire for washing machines safely and effectively
Quite simple, you can connect the grounding wire for your washing machine in 2 steps:
Step 1: Prepare a 2-meter-long electrical wire
Step 2: Ground the washing machine
Use a screwdriver to remove a screw from the back of the washing machine (note: choose a screw located on a metal surface for effective grounding).
Separate the two ends of the electrical wire, each end about 5 – 10cm long.
Twist one end of the wire with the screw removed and the other end with the grounding rod. Then tighten the screw removed earlier.
If you are not confident in connecting the grounding wire, seek assistance from electrical technicians to ensure absolute safety for users.

This article introduces you to the grounding wire and how to install it for your washing machine. We hope you find valuable information in ensuring electrical safety for every member of your family when using the washing machine.
