Thumbs up Strange or normal sound coming from burner?

The water heater turned itself last night. And when I restarted it and ran it for a few hours, it now has a hissing sound coming from the burner. Is this normal?

Its like water is dripping down into the burner and being burned up. Is it because there is condensation or debris inside that I haven't cleaned for years?

Should the flames be blue or orange?

It was orange for about 30mins and now it turned blue on its own. And now the sound isn't as apparent anymore.

Thanks for the help guys. I appreciate it.

Could be condensation if your temps are real cold outside and/or venting is an issue...or you could have a leak. I believe I've also heard of melting snow around the outside vent causing a similar issue. Where are you located? What brand and model and how old is it. If you don't know the age, post the serial number.

Well, it's colder here than there so shouldn't be a condensation or melting snow issue...and since it was working ok before, I doubt it's any sort of venting issue.

I need a serial number or the age if you know it....but if it sounds like sizzling water on a hot pan, I'd guess you have a leak. The flue from the burner runs up through the middle of the tank and it's pretty common for a pin hole leak to develop on the inner surface of the tank.

You should also inspect around the nipples on the top where the pipes come in. See if you find any moisture.

Another question. So is it supposed to turn off when the tank is fully heated?

Serial Number: 1012T401811

Well, it's not old....2010 March date of manufacture.

Yes, it should turn off after a reasonable time.

Sounds like you may have a thermostat problem if it isn't turning off, causing the water to boil. Is there any discharge from the safety valve?

No discharge. Nothing is leaking on the outside. Everything is dry.
