Here are 2 manuals that should help you in troubleshooting your RV hot water problem.
Multiple times there is a ref. to resetting the reset switch for 30 seconds on the unit (cover removal required)
For the ignition:
For the water heater:
The manuals as written are full of warnings mixed in with meaningful text. (Not user friendly)

Double check that washers inside fittings attached to back of tank, are not wedged or pinched in there restricting flow. Drain tank, relieve water pressure prior, obviously. The other thing is to check that the by-pass is allowing good flow in to tank when in normal operation mode. Have seen those only go half way inside valve, but lever is at wide open setting. If all that checks out, try removing the check valve on tank, and replace it with a 1/2" galvanized pipe nipple, ( or certified plastic/nylon fitting same size) and reconnect water line direct to that, without a check valve. That should do it if nothing else was wrong. Now you have a choice, either change it or leave it out if everything seems ok, but double check that hot water isn't siphoning back to another utility such as toilet if you leave it out and toilet is close. Feeling that cold line (inlet) when water is hot should tell you. I've seen the check valve in both locations, hot (at top of tank) and cold (at bottom of tank -inlet) Not 100% sure why, right from factory that way, but I say, put it on bottom fitting if required at all. Let me know how you make out.

I have an Antwood. Tank is very hot. Water from hot water taps is slighty wamed. The flow is good. I dont get it.
