No Engine Hot Water

[trvlngnrs]

The other day I drained the fresh water tank and flushed it. I also
drained the hot water heater. Now it does not generate hot water via
the engine, although it works fine on electricity. All other water
system components and functions are fine.

Any suggestions? I'm pretty sure it is another newbie screw up:-)
