surburban water heater

Just came back from our second camping trip and was wondering if anyone had a simular experience that the hot water tank shut off and trips the reset. If I shut it off and turn it back on, everthing is fine,the hot water tank goes on. Is this normal? I keep the water tank on the whole trip, is this okay or should I shut it off at night? We have a 2012 350 georgetown with a 10 gallon tank (surburban). Thanks in advance.

Trips the reset threw me.

The DC high limit switch?
The AC high limit switch?
The GFCI?
The main AC circuit breaker?
The DC Fuse?

Still confused. Sorry.
Are you talking about a light?

The "reset" light is only used when the water heater is running on gas.

If the burner fails to light the red light will come on. It will "re-try" to light 3 times and lock out. Turning the switch off; then on will start the re-try clock again.

That's what I ment,thank you.The reset light comes on and stays on, I do shut the power switch off and back on again and then the water heater goes on. Is it normal for the water heater to go out after it has been on all day and then you have to turn it off and then on again to reset it, also is it okay to leave it on all the time you are camping?

We leave our WH on all the time. It is not normal for the WH to go out. It sounds like you have a problem with the gas supply or have a spider problem.

OK, The 10 Gallon Suburban Water Heater Manual is in the Files Section of the Forum.

1) The water heater only runs when the water needs to heat up (water temperature below 100 degrees).

2) It knows it needs heat, because the 12 volt DC power switch is on and the high limit switch is closed (Opens at 120 degrees). This sends 12 VDC power to the spark and propane control board.

3) The Control board sends 12VDC to the propane solenoid that opens and lets gas out into the combustion tube. It also sends a spark signal to the spark control and 12VDC to the "reset" light.

4) The control board will open the propane valve for 15 seconds to purge the gas lines prior to sending the spark signal.

5)The spark lights the propane and heats the water.

6) The board continues to provide 12VDC to the propane solenoid AND the RESET light until the high limit switch opens at water temp 120 degrees.

If no ignition, the board will re-try the light cycle. A light cycle is a 15 second purge followed by spark. It will do this 3 times and lock out the control board. It may take many cycles if the propane lines are empty.

If you turn off the gas when you are not using it; then turn the gas on and try to get hot water you may experience the symptoms you describe.

OK, back.

My thoughts run similarly (propane problem).

1) You are shutting off the gas at the cylinder when you don't need hot water instead of shutting off the water heater switch. (long purge times may fill the lines eventually and then it runs fine.)

or

2) You have a blockage in the flue that is causing an over rich mixture that will not burn. (Lock out helps clear the rich mixture and allows a light).

Mine does the same thing. I called my dealer and he said probably spider webs. I haven't used a pipe cleaner yet to see if there are any in there. If it's not that, it may be a bad valve.
