After burner full heat cycle, on for several hours, no water, it is likely the WH liner will have cracked. I can look inside mine with a bright LED piston light for inspection. If there was some water in bottom, not all will drain, unless sucked out by vacuum, and add some Divine intervention, you may still be okay. However, a new WH may be in your future, as a cracked liner could not be repaired.

Won't help this time .. but when I winterize my rig I disconnect the wires to the water heater propane burner .. has come in handy on a few occasions when nephew/nieces start pushing buttons when exploring the RV.

1. The Red light ONLY comes ON when it fails to light on LP
2. Most Suburban and Atwood, if lit on LP and tank is empty, the ECO and/or the Tstat WILL trip from the Tank getting extremely hot.
3. So, if the RED light was on, the heater failed to fire or it did fire but locked out for some reason.
4. The REASON is probably the ECO tripped which on a Suburban is a manual reset. Just access the rubber cover below the Pop off valve and use a pencil to push in to reset it. Doug

Making sure the WH has water is an obsession with me....safety.

ANd even though tank was empty probably NO Damage cause due to High Temp T-stat Tripping/shutting down heating AND tank had opportunity to cool down naturally

Damage usually is done when HOT-HOT tank is filled with COLD Water

Naturally cooled HOT tank........basically a ' "oh, gee, sorry about that" kind of error to make.



Now that is has cooled down and you understand what/how it happened..........fill water heater with water, check it for leaks, fire it up and recheck for leaks
(Have to 'reset' that tripped Hit Temp T-stat-----RIGHT Side Button on 'Push to Reset Cover' )


Is it time for your medication or mine?

Thanks for the ideas! By crazy luck, I was able to reset from the back of the unit, red light now operates with the controls in the van. Maybe I'll get away without damage this time. I won't be pressure testing it until we get way south of this polar vortex in Ontario.
A special call-out to Doug and Old-biscuit - you guys nailed it!
