I have a gas powered electric hot water heater with an electric push button start.
Ever so often (more recently now even) the pilot has extinquished. I have to place the dial setting back to the pilot light position, and press the started button each morning to get it lit again, and then turn the dial to the desired heat setting. It usually starts right back up.

There's not any air travel or wind to blow this out as well.

Why is the pilot going out, and what do I have to do to fix it?
