DSI FLT stands for Direct Spark Ignition Fault
When you activate the DSI, the water heater attempts to light the propane burner. If it doesn't light right away it may show the fault light. However, it will re-attempt to light until the switch is turned off. If the propane does light the fault light will go out.
You need to check a couple things:
1. Are you attempting to use electric to heat? If so, you need to be on shore power, and there must be water in the tank. If you turn on the electric element with no water in the tank it will burn out the element and you will need to replace it.
2. Is the electric heater element switch turned on? This is normally an ON/OFF switch located on the front panel of the water heater itself.
3. Is the propane turned on? Check by lighting a stove burner.
4. If you open the propane tank valve too quickly, it has an internal safety that will shut off the flow of propane. Close the valve, give it a minute to reset, then open slowly.
