Gas water heater fails, then lights
Our DSI gas water heater ignites but then only burns for a couple of seconds. After a second or two delay, it tries again, and this time it always keeps burning. What's going on?

It is working like it is designed to work. The first time it lit and there was still some air in the line and it went out. now it is designed to try and relight 2 or 3 times more before it locks out and displays the "failed to light" indicator, and you have to turn it off for a few seconds and then turn it back ON so it will retry until it lights or fails to light after 3 more tries. One thing you can do to help eliminate this problem is to light the kitchen stove and let it burn until it burns clean and all the air is expelled, then try and light the water heater. Works for me and as a bonus the refer will also light easier after you expel the air.
Hmmm. Well, it does this every morning. If there is air in the line every morning, that suggests a problem?
