Water Heater Problems

can you hear the spark igniter "clicking" when it tries to light?

Yes, I can hear the igniter clicking. It will sometimes "backfire" but not light unless I shut it down for a while.
There's definitely an issue with your heater if you're hearing blowback. Check the main burner tube and where the burner injector tube enters the large burner tube. Spiders love to build nests and webs in these tubes and there's not enough pressure to blow them out. A small wire from a wire brush should pass through the actual gas jet, the other tubes are large enough to use a flexible brush or similar.
There's a sensor that senses flame when it "rolls out" of the burner, it's called a roll out sensor! Could be that's what's happening.
