Hello good afternoon, 2 months ago I bought a used Orbis water heater is like new, I had no problems but 3 days ago I have no hot water pressure. It all started because I ran out of water in the tank, I had to buy an engine because the water didn't go up to the tank. After loading the tank, the heater started with this problem, at first it lit the flames a little when it opened the kitchen. But not now, it's just a pilot. If I open all the hot water tap, I get a single tap and barely. I had read around leaving all the hot water tap open with the water heater turned off so that the air it could have taken when it ran out of water was gone, but it was not the solution. Empty the tank doing it, once alone. Any ideas ?? Thanks in advance. The engine was very expensive, I hope to fix it here before calling a plumber.

Dear Luis: Attentive to what was stated by colleague Elktomaq, to whom I take the opportunity and cordially greet, I would like to add that the advice given by him corresponds to one of the ways of purging the air contained in the pipe. I would like to add that one of the causes for which the pipes are clogged is that when the entire water tank is emptied, it usually carries impurities and / or garbage cans and they are housed in the filter located at the venturi inlet. The venturi is that piece to which the flexible is connected and from which two thin pipes are connected to the diaphragm. To clean it you should do the following: When you disconnect the right flexible (facing the heater) try to observe from below and you will find a conical spiral shaped filter. You should take it out by helping you with a pointed pliers or a screwdriver. You clean it well and put it back on again. In case you do not have this filter because it was already removed and did not replace it, try to unclog the venturi duct with a fine wire trying to drag out any impurity or trash you find. I hope it helps you. Hugs.
