Generally, it is the sound when the gas in the water near the heating pipe in the machine is precipitated and then burst. The heating pipe itself is very hot, and when it comes into contact with low-temperature water, there will be violent water agitation, which will precipitate the dissolved carbon dioxide gas in the water, resulting in noise.

1. As long as heating is started, the high temperature generated by the heating of the electric heating tube will cause the water close to the surface of the electric heating tube to heat up and rise, and the water will move in the whole electric kettle. Because water contains a certain amount of air, air will escape from the water surface during the heating process, and these processes will make a sound.

2. The electric water heater is a high-power electrical equipment, and the working current is quite large, which is likely to cause some electrical contacts to be damaged and spark. Please check it carefully to avoid the accident from expanding.

3. It is possible that the scale on the surface of the heating tube is too thick, and the heat cannot be transferred to the water in time, which makes abnormal noise. It is recommended to contact the manufacturer to clean the scale after sale.

4. Abnormal sound caused by heat not being conducted to the water in time. The abnormal sound of the electric water heater may be caused by excessive water pressure, or excessive scale accumulated on the surface of the heating pipe, and the sound of the safety valve discharging water and releasing pressure.
