Calefón enciende pero no calienta el agua

Today we came across a 26-liter Instamatic water heater. It had a very common problem: it would ignite, but the water would only come out lukewarm or cold. The first problem is usually a faulty water diaphragm; replacing the diaphragm fixes it. However, in this case, the gas diaphragm was damaged and had reached the end of its lifespan. That's why, when the water heater ignited, the gas couldn't flow properly, and the water wasn't heating. After replacing the diaphragm, the water heater is now working perfectly. #waterheaters #boiler
