Gar Water Heater "Fault" signal

[kdmccarthy46]

We have a 2015 Tiffin Red and find that the gas water heater fault signal comes for about 15-20 seconds and then the gas heater starts and the fault signal disappears. This seems to have started when we filled our propane tank which was on empty. The electric water is working fine as well as stove and gas furnace.

Any thoughts about how to correct or if this is serious enough to take in to shop?

Thanks

The water heater's "FLT" light in our rig illuminates every time the gas ignites. It always has.

That's the way most RV water heaters are wired.

That is actually normal operation. You must have not noticed it before getting propane but there is nothing to fix. Just relax and enjoy your RV.

As others have said, normal operation. The "fault" is that gas is flowing but the control board hasn't (yet) sensed a flame. As soon as the board verifies the burner has successfully lit, the fault light goes away.

Mine did not but yes many are wired When it calls for heat the fault light comes on till it detects FLAME then it goes off.. As long as it goes off.. Don't worry about it .
