Thanks for answering.
Does the diaphragm also regulate the intensity of the flame or does it only cut or ignite when water passes?

Sorry I don't know how to put images here, the two links came out together, there are the two images here: https://imgur.com/a/EpdOSy8
I leave one of your images modified. You must loosen the screws marked with green and the body of water marked with red will come out. Inside this is the rubber that you must replace. Remove the two fine pipes that connect the water body or diaphragm holder with the water heater.
There are two finite metal tubes that go to the water pipe, those also remove them to take out all that? Does that change what's inside or do I have to replace everything? Thank you
Thank you, any special care you have to have as a sealer once I take things out or something like that apart from cutting off gas and water? I'm going to do it tomorrow and I hope I don't screw it up and run out of direct water.
They are all metallic, I was afraid especially of touching some gas but if it is only water I will disassemble it tomorrow, thank you very much tomorrow I update as it was.
I could already disassemble it but I can't take out the diaphragm, it has a half riveted washer, it has no screws as I saw in some images of others, it has a washer on both sides of the wand and it has no grimace to take out or spinning or anything.

I could fix it, thank you very much, I ended up changing the entire water chamber, it is sealed, even so I managed to take out the riveted washer carefully, change the diaphragm, I put the washer under pressure and the water heater worked very well but lost water, even though he tightened the screws of the water chamber (the 6 he has) he still lost water through a hole he had. They told me that these cannot be opened, that they are like that ... a shame but at least the water heater is already working.
