Yesterday morning I had the unpleasant experience of taking an unplanned lukewarm shower. No,it didn't wake me up any as I had been up for over 2 hours and already had my coffee ;) Went down and checked the 2009 HWH, and the water tank was cold and not firing. The relief valve had also ejected some water into the bucket that is there just for such an occasion. I had actually checked that bucket last weekend when I cleaned the pellet stove, and it had been dry at that point, so I was confident that was a new issue.
Left a message with my repair place and they scheduled me in for between noon and 2. Then the guy called before 10 and said he was on his way over - great! So the guy came in and hit the reset and then the piezo lighter and it fired up. He figured that the wind had blown it out. I was skeptical because that had never happened (and although it had been windy, it hadn't been that windy), but what the eff do I know? But he had to go pick up another pressure tank so he let it run while doing that. When he got back, the burner had gone out, so it wasn't wind.
After tearing into it, he found that a rod had a bunch of build up and he cleaned that off. He also removed a bunch of cat hair/dust from the lower filter to improve the air flow. Then he called the mfg to make sure he didn't need to look at anything else before firing up. I was standing there during the call and they said it should be all set. So he fired that puppy up and waited around to ensure it didn't go out. Success. Now that thing is pumping out wicked hot water even on setting "A", which according to the manual will produce 130*. So will probably reduce it to the setting before that, which should produce 120* water.
And, this morning it is out again - argghh!

Well...at least it sounds like you have a diligent tech to call on. We used to have the occasional "blow-out" of the pilot light by wind (as did Elegant Friend whom I taught to relight the pilot light - a real accomplishment for her), but I don't think we've had a problem with our current HWH (2016 - previous one had lasted but 7 years). That could be affected by the installation of the HE furnace (2014) that does not vent through the roof. I can't recall the configurations of the two exhaust systems.
