No pilot. Your water heater has DSI (Direct Spark Ignition). The way it is supposed to work is that when the thermostat says the water needs heated the control sends power to the spark rod and opens the gas valve at the same time. If you are standing next to the water heater you should hear the spark (snap, snap, snap) and the gas valve should make a soft clunk sound. If you hear those sounds then they are operating properly and there is a blockage either in the orifice or even the screen in the inlet of the valve is plugged (unlikely). There is also the possibility of the control board failure. That could manifest itself in a few ways, but the end result is the same. Some of the time you can look at the board and see a burned spot on it. IF by chance you need a board, the one that seems to be the best on the market is a Dinosaur Board (
Dinosaur Electronics Home. High quality circuit boards for RV appliances.). The boards are very easy to replace, just pretty much plug and play.
