1. The bullet on the lid of the electric kettle can't be lifted, because his snap ring is broken, that is, the joint between the lid and the body can be directly removed. If it is integrated, it will be scrapped directly.

2. The switch of the electric kettle is a steam switch, which can't be jammed when pressed, indicating that the contacts inside are damaged. First open the base with a screwdriver. Screw the wires on the handle together with a screwdriver. Remove the outside of the handle. Remove the steam switch. Install a new steam switch.

3. The reason why the electric kettle doesn't trip when it boils is that the temperature control piece inside the handle doesn't work. When the electric kettle is used for a long time, water vapor will be generated inside the handle, which will eventually make the temperature control steel plate rust out of control.

4. First, temperature control deformation does not generate thrust, resulting in power failure. Second, the long-term use of the power-off contact heats up, which makes the plastic base deformed and the contact is disconnected without electricity. In this case, it is recommended to replace the switch as a whole. The electric kettle adopts the integrated design of switch and temperature control.
