Rheem electric water heater reset button

Hello everyone, I have just received a 38 L Rheem electric water heater, the first day it worked great and then it didn't heat up anymore; The water comes out warm. I have two doubts: 1. The installer used CPVC tubes and not copper; Could that have caused a problem? Is it enough to change the connections for copper? 2. Reading about similar problems I have learned about the existence of the reset button and I want to try that solution first; but I don't know if I have to press the button with the hot water tank connected to the electric power and on or if I have to press it with the power switch off, that is without receiving electric power. Thank you very much for your help.!!!

Hi. With the change of pipes you will not achieve anything. The temperature does not depend on this. There are several options to verify. It is necessary to check that in the cold water inlet there is a pipe called fisherman that takes the water towards the base of the thermos. It must also be verified that it is set (from the thermostat) at a medium / high temperature. With respect to the safety thermostat, that is, the one you press is indistinct if you press it while the thermos is connected or not. Do it with the device plugged in so you will verify that it turns on. Regards

Thank you very much for your quick response. I tried to reset it and it didn't work.
I remembered that during the heater test week, there was one day that the water supply tank was empty, the water ran out. Is it likely that the resistance was burned if it ran out of water? Or do you have any automatic system to detect when you have no water?
And one more question, how could I prove that resistance is what doesn't work?
Thank you so much for your help.

Actually, the fact that the tank runs out of water does not mean that the thermos empties. If water does not enter the thermos, the contained water will not come out. This means that it will never remain empty so that the resistance is burned. The only way to empty a thermos when it is full is by its purge tap. This means that the resistance could not be burned by being "dry" or without submerging. On the other hand, to check if the resistance is burned, it must be done with a continuity scale tester or low resistance.
