Any guidance? Do I need to replace entire w/h unit? Causes?

Does the water heaters electric element work? If not, then you could have burned up the electric heating element (very common). Also depending on what else you have running in the RV, the Suburban electric heating element is 1440 watts by itself or 12 amps when heating. That's going to be a good load on the little Honda itself.

Most people don't try to use the water heater on electric when dry camping, and you are going to be very limited on just what you can use with a small Honda like that, which I think is around 1600 running watts. (don't quote me on that)
These are also some good articles to help understand watts/amps/etc.

as well as the watts/amps your converter uses when hooked to a 120 volt power supply (either shore power or a generator), which many people overlook:

IMHO, I just think you are overloading the Honda. May want to only run the water heater on propane since using the electric heating element would also consume 90% of your generators running capability just by itself. 1440/1600= .90
That wouldn't leave you much to power anything else.
