Water Heater NOT working

[tamkel31]

I have a 94 Fleetwood Pace Arrow. When I go to turn my hot water on nothing comes out. Last year it worked just fine. We had it professionally winterized and have flushed the lines, but now nothing. Am I doing something wrong? I flip the switch above the stove and the water heater pilot acts like it is trying to kick on, or it kicks on and I still have no hot water. The cold side works just fine. Any help would be great!

Hey OP.........

DO you have NO water flow on hotside?
Water flows but is NOT hot?
Water heater doesn't heat?


Hello.......

X-4 on bypass noting that he did not do the winterizing himself so might not have thought about bypass.

TO follow 2Oldman's comment, the water heater is pretty noisy when it's on. I suggest you turn it on, go outside the coach to where the water heater is located, to make sure it's one or not.
If it is on, let it heat for a while, then check to se if you have hot water come out of the pressure relief valve at the hot water heater. If there is, then this is a pluming issue.
If no hot water, this could be the heater's igniter, or fuseable link. Mine went out last years, bought one, installed in about five minutes.
Good luck, hope you find it.

One caution I have not seen yet is that the OP needs to make sure there is water in the heater tank!
Running the propane on an empty tank is not a good idea!
(Even worse if it was electric).
OP - gently release the temp/pressure valve on the tank to see if you have water in there. If not we are back to the bypass valves.

That.... Is known as SUSPECT #1

Suspect #2 is a check valve.. Many water heaters have a check valve on the outlet.. absolutly required if you have the single valve bypass.

This can crud up and refuse to open.. Causing the same thing to happen.

But I'm going with Suspect #1 since you had it winterized.

I always did it myself.

Three ways to winterize
Wet method. Fill lines with Pink stuff and have fun flushing it out come spring (yuck)

Dry Method.. Fill lines with AIR, if it freezes you won't be worried about your RV (blow at least 10 times to insure you get nearly all the water out.. Read file in library to do it right)

And the best method.. The S method.

Strap a snow blower on the front of tee rig.. Turn so compass points toward the eqator (most folks reading this that will be South, hence the name S method) and when you stop for fuel and someone looks at the snow blower, scratches his head and says "What the !!!! is that for" you are winterized.

same thing happen to me it was check valve gone bad inches from the water heater tank u will find it easy to replace

agreed hard to tell by your post if you have NO water or NO HOT water. If no hot water, do you have access to the pressure relief valve on the tank or can you feel the side of the tank to see if the water is hot in the tank? That will at least tell you if it is a water heater problem or a bypass valve problem.

Maybe, but then cold water would be coming out. OP says "nothing".

OP, you need to check your bypass valves to make sure they are ALL in the "Summer" position.

Umm.. it takes 20 minutes to heat the water. If the WH is working on gas, you'll know. It makes a pretty loud noise.

What is your issue.........

No hot water comes out of faucet---any faucet?
Only cold water comes out of hot?
Water heater doesn't heat water/doesn't work?

Hard to tell from your post.


No hot water flow.........bad check valve on hot outlet of water heater (inside nipple that is screwed into tank....top connection)

Cold water from hot.......water heater bypass valve Open

Water heater doesn't work..........which water heater (Brand/model) and what does it do/not do ??
