Monitor panel on 2017 Sprinter 5th wheel

Dose anyone know what the red light is for on the panel
That reads Dsiflt
The led light is in the middle of this acronym. It doesn’t come on a lot but I’m just wondering what dose it mean when it lights up red
Thanks

DS FLT will light when you start the water heater on LP. It will go out when the flame lights.

My dsi flt is as Chuck said. When turning on LP to the water heater the lamp illuminates indicating a direct spark ignition (dsi) fault (flt) until the gas ignites then it goes out.

If the light stays on for more than a few seconds, that means your water heater did not ignite and has gone into bypass. Most likely caused by air in the lines. Always purge the lines by lighting the stove first and let the burners run for 20-30 seconds.

You refrigerator (if LP) and the furnace have the same feature. It’s a safety action that shuts off the gas flow to the appliance if it doesn’t light within a few seconds. It prevents a dangerous gas build up. To clear it, shut the switch off, purge the lines as mentioned above, and then turn the switch back on. It should light at that point unless there is a different problem such as a spider web in the flue.

I know you’re not currently having a problem and just wondering what the light was for, but figured this would be a good time to provide additional explanation.
