I had trouble with our water heater in our Bighorn fifth wheel,I changed the anode rod and thought I had my problem solved. After 2 or 3 weeks it quit working on electric again, can anode rod be bad that soon? Last one lasted couple years.

anode rod has absolutely no baring on if the water heater works or not...gas or electric.Are you sure you had water in the tank when you turned on your water heater? If not it only takes a few seconds to burn out the heating element..(easy to replace)Also check the fuse.

Yes it was working and quit on electric, replaced worn out anode rod and it work 2 to 3 weeks, now not working on electric again.

Anode rod has NOTHING to do with heating on electric and/or propane.It is a 'sacrificial' used to protect the glass-lined STEEL tank Suburban uses.Electric heating element is under the cover next to drain plug.AC power comes from your AC Panel via a circuit breaker.AC Power goes thru On/Off switch (lower left corner in outside compartment-----may also have another On/Off electric switch inside if RV Mfg. added one)From switch power goes to the set of AC thermostats (under cover above gas valve with 'push to reset' left one /right for propane)Then from t-stats (High/normal) to elementIf your Circuit breaker has not tripped and On/Off switch is ON......Push the Reset------if you feel it reset then it will heat until t-stat trips again.That means 'normal' t-stat is not opening when it should and High temp is tripping to stop from over heating the water. New set of AC T-statsIf high t-stat is NOT needing resetting then electric element wiring could be loose or element bad. Tighten terminals screws if wiring loose. Bad element replace it.Also check the wires on set of t-stats.....sometimes the rolled lip were cut out is for t-stats will cut insulation on wire...shorting it

Lots of good info here for you, hope you get it straightened out. Just for comic relief, I will tell you about when I had a similar problem last year. It worked fine on propane, but had stopped working on electric. I checked everything ( I thought) but wasn't till I was draining everything for storage that I saw a switch inside the outside cover that I had forgotten about ( was our first summer with this rig). Sure enough, with the switch turned on, the water heater worked just fine. I vaguely remembered turning it off when I was flushing the water system after we had bought it. Good luck and hope it's not a serious issue.
