I just had the same issue with DSI FLT light on my 09 Jayco Eagle 345 BHS. While troubleshooting, I found the igniter harness had come loose from the igniter (on my heater it is orange harness RH lower side that connects to gold blower that heats the tank). Upon reconnecting the DSI FLT light went out and I was able to get hot water on electric and LP. My initial fault was that there was no hot water when running off electric only. I then tried the LP side and the flame would light for about 3 seconds then go out. I was informed by Camping World Service that the DSI FLT will shut down the relay panel that controls the water heater not allowing either side (electric or LP) to work - additional safety.
