Metal eroded disc laying on burner inside an A.O. Smith 75 gallon water heater.

We found a metal what looks like a disc laying on the 2 burner plates inside the AO Smith 75 gallon water heater. The unit ignites for a few seconds and then shuts down. Is this disc needed, what is it, and where would we buy it? We think it is a flue baffle. Can our heater work without it in the meantime - considering safety. Thanks all!

Welcome to the forums.

The flue baffle is usually a spiral piece of metal. Not sure what you have floating around there.
Possibly a burner cover to keep condensation from hitting the burner.
Post the full model number of the ID tag for us.
