Cold days usually mean hotter showers. And with that, an annoying situation often occurs: The shower's heating element burns out. Remember that "heating element" is the common way to say it; the correct term is resistor, so when I say resistor from now on, you'll know what I mean, okay? And why does the shower's heating element usually burn out on colder days? Well, a resistor is basically a controlled short circuit. And since a short circuit causes a conductor to heat up, it ends up that, while this short circuit heats the water, it simultaneously maintains the temperature of the heating element so that it doesn't burn out. Since on cold days we turn on the water less to keep it warmer, less water passes through the heating element and it ends up heating up more until it breaks. Okay André, so far so good, less water burns the resistor, but what about this anomaly of turning off the shower valve but it remaining on? That's news to me. Well, my friend, when this happens, you might be lucky enough for the resistor to simply burn out or, in the worst case scenario, the system might heat up so much that the shower's plastic will melt and, in some cases, even catch fire!!! And why does this happen? In some showers, the electrical contact depends on the shower's water pressure. Therefore, the less water that passes through, the greater the risk of poor contact. And this poor contact can cause the terminals to "weld together" and, even when the water is turned off, the contacts will remain in contact. Some might even think at this moment: "Just changing the selector switch position with the water off will loosen the terminals." Never do that!!! Moving the selector switch with the water running and the shower in operation is very dangerous. Remember, the shower is energized and you are wet; in this case, you could have a very serious accident. And if you know someone who does this, send this video to them! And just in case, share it in WhatsApp groups too; maybe someone is thinking of doing this crazy thing, let's save their lives… Okay André, but is there a way to avoid this problem? Of course there is. We decided to create a step-by-step guide so you can perform preventive maintenance on your shower yourself and avoid this from happening. For this step-by-step guide, we will use this Lorenzetti brand shower. But you can replicate this step-by-step guide on any shower. What you will need is: 1 old toothbrush, 1 screwdriver, 1 nail file, 1 needle-nose pliers (or long-round pliers), and 1 roll of Teflon tape. A warning: If this defect is occurring within the manufacturer's warranty period, do not attempt this to avoid voiding the warranty. Agreed! Let's go, the first step is to go to your electrical panel and turn off the shower's circuit breaker; Now remove the showerhead and take it to a more comfortable place for you to work; Unscrew the showerhead. To do this, simply turn it clockwise; Now release the ground cable that is attached to the cover and remove this cover. Be very careful not to damage the rubber seal between the chamber and the cover to prevent future water leaks; With the chamber exposed, you will be able to see the heating element and the diaphragm, this rubber seal that creates contact between the terminals; With a toothbrush and a little detergent, thoroughly clean the chamber and diaphragm. Also, clean the inside of the tube in the cap you removed. This tube carries water to the diaphragm, causing the contacts to close; Now, using a screwdriver, remove the top part of the showerhead; Use a nail file on the terminals to remove any dark residue. During this process, the metal plate may bend slightly. To readjust the opening between the terminals, place the file on the fixed terminal and, using needle-nose pliers, bend the metal plate upwards. Do this on both sides to ensure the openings are identical; Now, clean the diffuser using the brush and detergent. If there are any clogged holes, use a needle or pin to unclog them. Finally, simply reassemble everything and reinstall the showerhead. Before turning on the circuit breaker, open the showerhead and let the water run for a few seconds. Therefore, the chamber will be full of water when you turn on the shower, preventing the heating element from burning out.
