I have a LE3505 Weekend Warrior and over the weekend I couldnt get any hot water out of all the faucets.
When turning on any faucet to hot nothing comes out.
There is water in the hot water heater.
It worked Saturday morning, then Saturday night nothing.
What could be wrong???
Any ideas??

Blown fuse, I believe on my old warrior there was actually a wire with a built in fuse that I bypassed. Not sure what there called.

Out of Propane ?? LOL

No water at all coming out?

No water at all coming out of any faucet or shower
Cold water does come out when on cold setting

Could be plugged with sediment.

There is a valve to bypass the water heater. Pass side compartment, look up.

Easy to hit it with a chair or something when you load up. No hot water at faucets, but its hot at the tank.
Dont ask how I know that...

There is also a thermal fuse right at the board on the water heater, that would make no hot water in the tank...

I was going to say that but the OP stated twice that he was not getting any water, hot or cold.

Perhaps there are isolation valves that could have been bumped.

Bypass Valve is not on.
I cant fugure this thing out.
Why would there be cold water on cold setting but no thing coming out of hot water setting on any faucet or shower.
There is hot water in the water heater.

Any ideas???

You could try removing the T&P valve, turn on the pump and see if water comes out.

Turn off the pump, and the heat source for the water heater. Use a 7/8 socket or wrench, and pull the (?) white drain plug out. See what comes out. If it's a lot of white chunky stuff, let it drain, and refill. Fluch the lines out, if you can. That may involve getting to the back side of the water heater. Figure which line is from the tank, and which one feeds the trailer, and fluch that line?

Not to insult yore intelligence, but you have to go from the known to the unknown. Take it 1 step at a time. Water in the water heater tank? Water in the lines from the tank? All faucets not getting water from the hot knob?

You can take a hose from yore compressor, but be very careful, those lines are a type of plastic. So, don't use any more than 15-25lbs. of air pressure, if you decide to blow the lines out.

Let us know what happens.

Ended up being the check valve in the back of the water heater tank.

Thanks for the update I was curious what it ended up being. Glad you got it figure out and For cheap!
