Thank you Eggscape. Good thought but no. I looked. And I never did put it in bypass mode. I drained it in September, and blew it all out dry with a compressor. Still head scratching. Local help is sparse at the New Year.

Just drove 4 days. No hot water. Replacing element is easy second time around (two way Suburban heater). So I bought new and replaced. Still no hot water, from gas or electric. Not sure how to trouble shoot. Dang. Left my multi meter at home. May have to buy another.

Breaker is fine. Stove and gas furnace work well.

When trying on gas is the interior red light coming on indicating it is trying to fire?
Maybe check the high limit reset buttons on the exterior under the black rubber? If not that then maybe a bad control board

Supposedly the universal Dinosaur Electronics boards work too

The reset buttons were fine. I'm an idiot. I replaced the 110 element but never turned OFF the off/on switch. Did that and gas came on. Now I can take a shower. And take my time figuring out why 110 still doesn't work. Thank you everybody.

Uh, the electric on/off switch has nothing to do with the gas lighting.

I run my hot water heater with both gas and electric on a regular basis - it makes it like a tankless hot water heater with an somewhat endless supply of hot water!

Something else is going on than the on/off switch. The gas circuit and the electric circuit are separate - neither controls the other. The only device common to both circuits is the thermostat and even there, the two circuits are controlled on separate contacts - one DC and the other AC.

I'm glad you now have hot water but I don't think your problem is solved. Maybe the act of switching the on/off switch jarred something that was a little loose and that is what the problem with the gas circuit actually is.

Your gas lighting problem is likely to come back until you find out exactly what is causing it. By the way, intermittent problems are the hardest to solve - I wish the best of luck in getting it repaired.
