We're probably gonna need a bit more information before anyone can help.
First question... do you not have the owner's manual for it? If so, there's probably a troubleshooting section in it.
If not, the next thing is to figure out what make & model number unit you have. Is is an Atwood heater... Surburban... or something else? Then to narrow it down more, find the model number.
Now this next part of your statement troubles me: you ask, "...and where is the access?" I'm not trying to embarrass you in any way, because we were all new to this stuff once. But are you saying you don't even know where the water heater panel on the exterior of you rig is? If that's the case, you should probably just stop right here and either take it to a repair shop, or look for a mobile RV tech who can come to you.
But if you insist on trying to do this yourself... the access panel is usually a square panel on the same side of your RV as the kitchen. On my RV, it's the panel circled in red below
It looks like this:
From here, you should be able to get the make & model printed on it somewhere. Then someone can probably begin trying to help you out. Could be something simple as a loose or damaged wire, or it could be part of the circuit board needs replacing.
