Why does the electronic water heater sometimes have a "click" sound when it is heated?

If a sound similar to “rumble” appears when the water heater is heated, this may be the sound of the air in the water tank being heated and then expanded to separate from the water. It may also be the sound of the water being tumbling inside the water tank after heating, which is normal work. Sound, please don't worry about using it with confidence.
