Hello, I have a recent problem with the water heater, the model of the title, it goes well, it turns on well with the kitchen tap (which is next to the heater and has more flow) with the shower also turns on well but with the bathroom tap No and before I turned on. What also happens is that the flame is low from the burners and until recently it was very strong, it is like now at most it is half as much as before. I do not know if it is a repair that if or if I have to do a gas or is something that I can end up doing. Thank you.

Hi. We should start by checking and changing the diaphragm rubber. It deteriorates over time / use and stops working properly. If you upload a photo of the heater without the cover we can tell you where to repair. Regards

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

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

Only the inner rubber is changed. In a hardware store you can buy it.

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.

It is not necessary to cut the gas. In the area there is only water. The only thing that can happen is that if the hoses are plastic they are dry and break. It is common since they dry out over time.

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.

Take the whole piece to a hardware store. They will replace it.

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.
