I bring to your attention already 82 questions for the heading "question-answer". This question came from a reader who identified himself as "Marlene" with exactly this title (I did not change it). If you have your own answer to the question, then write it in the comments below. I and other readers of my channel will be happy to read it.
The text of the question itself is as follows, unchanged:
Hello, changed the heating element in the boiler. The water continues to shock. The wiring is ok. The house is private, in the plan no one was grounded on pipes. The question is, what else can you check and how?
After considering the issue, I consulted the reader within the framework of my knowledge and qualifications as follows:
In the described situation, it looks more like insulation damage, but not necessarily the cause is in the boiler. It is no less likely that the phase conductor to the water comes from a completely different source. Try to disconnect the boiler from the electrical circuit, if the water stops beating with an electric current, then the reason is really in the boiler, if not, look for the problem elsewhere.
If the reason is in the boiler, then I recommend checking the entire device in stages, for this:
- disconnect the boiler from the electrical circuit - this is a prerequisite for electrical safety, you should never open the electrical part of equipment that is known to be faulty.
- remove the heating element - it will be more convenient for you to work on the floor, remove the housing cover.
- start checking the insulation of the device in stages, it is advisable to use a megohmmeter for these purposes, but if there is no one in your home arsenal, use a multimeter.
- start with a tank for heating water - one electrode is installed on the tank, the second is alternately supplied to power outlets, wiring elements, parts in the immediate vicinity or even come into contact with metal.
- in the position where the insulation is weak and the cause of the breakdown or lack of insulation is located.
