Your electric shower doesn’t heat up, usually gives small shocks or worse, does it smell like a burn? Then it was time to change it.

Before purchasing your shower, check its voltage compatibility with the installation location. Furthermore, it is essential that the thickness of the wiring at the installation location is compatible with the thickness of the wires in the shower purchased. These details are very important to avoid overloads and short circuits.

For your safety, work with the appropriate epis, such as shoes with rubber soles and gloves. In addition, the ideal is that the ladder also has a rubber base, as well as its tools.


Turn off the main switch or circuit breaker that corresponds to the installation environment. Then close the general water valve that feeds the shower pipe.

After that, turn on the shower valve to remove the accumulated water inside the shower pipe, then close it after all the water comes out.

#FG TIP: Use a porcelain connector instead of insulating tape splices, as the wiring heats up more frequently, which can melt the splices and cause greater damage to the electrical system.


With the cables connected and before turning on the shower valve, make sure the shower switch is set to the cold temperature option (shower off position).

Turn on the valve and let the water drain for approximately 1 minute to remove possible air bubbles from the plumbing and fill the reservoir in the shower diagram. How to unclog clogged pipe

IMPORTANT! Do not turn on the shower without water as, if this happens, the resistance will burn out.
