Water heater not working

[BruceLuh]

I have a 1995 B190 motor home. I am on vacation and the water heater isn’t working. When turning it on, I hear the igniter work the light goes off inside. Then, the light turns back on.

Any suggestions to help me are appreciated.

Since it seems several issues with things propane related... I am going to guess that it is a bad pressure regulator?

Others with more knowledge will sure chime in.

Have you checked for mud daubers?

Are you out of propane? Does the stove light to verify that you have propane ? Do you have 12 volt power to the heater board? What voltage are the batteries? All of the above will cause problems lighting the water heater. Check all of these, then look at the burner orfice to see if plugged. Good luck Chris
