The wall of the bathroom was broken, and I used a voltage tester to find that there was no electrici

One of the three types of insurance is the fire wire, one is the zero wire, and one is the ground wire. If none of the three testers do not light up, there is no live wire. In this case, the line of fire is broken.

The power cord is thicker and will not be broken in the middle, which is generally a problem at the joint, such as loosening from the place where another plug is tapped, and the contact is not good, if it is not taped from the socket next to it, it is loose or broken at the far end and the main line connector. In the former case, it is more easy to do, disassemble the socket next to it to check and reconnect it. If the latter case is troublesome, find the joint with the main line open to check for repair.

FYI.

Generally, the electricity comes from the wall plug wire that is close to it, open the wall plug closest to it, see if there is an open place, and connect it. If it helps, please adopt, and the phone clicks on the upper right corner of the satisfaction, thank you!!

It should be that the line in that place is short-circuited.

Let's see what others have to say.
