Don't you just hate it
When you fix something and you don't know what you did to fix it!!!
All at once, no hot water at any outlet. Good cold water flow at all outlets. Some hot pressure when I first turn on the faucet, then it goes away. Coach is hooked to shore water. Not using the water pump. My pea brain says Ah Ha, blockage at the water heater since all outlets affected.
2005 Adventurer, Atwood heater. How the heck do you get to the back of this thing?? Exhausted search on internet so under I go. Found access panel(see pic). With that removed I couldn't believe my eyes. See pic. There was all kinds of room in there. The top connection is outlet with a check valve. I took that apart and everything was clean as a whistle. I opened the kitchen faucet and could blow thru the line both ways.
Here it comes!!! Put the damn thing back together and it works like a champ!!!
DON'T YOU JUST HATE IT

Pick up a spare check valve ( or a straight connector to by-pass it) .
Murphy says you'll need it . AT the worst time possible.

Agree the check is in place so that when winterizing the hot water heater does not fill up with antifreeze. It must have been stuck and you freed it. Agree with Skip purchase two check valves, replace the current one and one as a spare. I had the same problem. The check valves are very inexpensive and can be found at most plumbing supply stores.

Same experience here I was camping and had the same problem we have a Winnebago Voyage and had to reach inside cupboard where water pump was and reach around back of tank disconnected the check valve line as it was late and in the middle of nowhere decided I would drill out check valve once cleared I reattached line hooked every thing back up worked like a champ. I' don't do antifreeze so may not replace as it has no other real function and doesn't appear to be a problem as we've camped many times since. I wouldn't necessarily recommend this action we didn't have to many options and the tank fitting was extremely tight and with limited space to work made using my drill to drill out check valve less risky than possibly shearing the fitting off in back of tank.

Yep, just like others have said. Your check valve stuck closed. Not at all uncommon.

Your thread title is a good fit for me and my smart phone.

Yes as others stated you unjammed the check valve.......just a plunger/spring/o-ring assembly
O-ring gets cockeyed/plunger goes sideways....calcium/crud particle gets stuck.....NO HOT Water
You have LOTS of room..........gut that check valve and install a HOT OUT shutoff valve. Sharkbite 1/2" is an easy install.
Yes you would have to access it each time you winterize/de-winterize but shutoff valves work.

After buying several check velves I got tired of installing them as my arm was 3/8" of an inch to short. Five years ago I just drilled them out and know problems since.

I know you can't see from my pic but I am pretty sure this is the original check valve and this is the first time it has been messed with. Like yours, my coach is a 2005. 13 years and mine decides to stick closed and you have been down this road several times. Water condition? Use? Who knows!! All I know is what my buddy Red Green says. We are all in this together!!!

I seem to more closely resemble Joe Blyfstyk from dagwood comics.  You know- the guy with the black cloud following him.
