Hello, yes, I am referring to an electric thermo tank (in Uruguay it is called a water heater). At this moment I finish assembling it again, since I emptied it and performed several more UNNECESSARY tasks !!! since it was a "button" (security I guess) that has the thermostat, which is half hidden, but hey, I reset it, let's say and it worked again. A pity that I did not notice it before doing everything I did, since the butts must now be prayed so that they are not "losing" (dripping). THANK YOU
