Water heater won't light

I believe we may have ruin our hot water heater. We are new to RVing and we have a 5er. We were not aware of a bypass for the heater and tried to light it thinking there was water in it because the water was coming out of the hot water facet. How back it this? It will not light and we can't figure out why. Any info appreciated

Wow we tried the electric on the water heater (after we let it cool down) just in case we did not burn up the element and it worked. Woo Hoo

Well, when I got home I tried starting the heater, it would not start, it did one time and stayed lit got several seconds. I decided to check all the connections, and the one with the orange cover was not connected, after connecting it it lit. Thanks again to all

It sounds like you have rust in the propane burner. If you have access to an air compressor, try blowing the rust out. Nine times out of ten this works.

We have pushed the reset buttons but they don't seem to work, do they pop out when they need reset?

Gjac, That is exactly what is going on

We will need to replace the element, but now we cannot get the gas to pilot to stay lit for the gas help

Sorry about the repost, didn't see the other so I thought I forgot to hit post

Post what you are seeing. Does the LP make a clicking sound, the flame comes on for a short time then shuts off?

Odds are the LP limit switch tripped- make sure to press both reset buttons shown on OB's picture.

I do believe we will need to replace the element.Now we can't get the gas to light. We are having a heck of a time. Hope someone can assist

If you had the electric heating element on you probably toasted it. You can purchase the heating element at Home Depot. I speak from experience.

W/o water in the tank, it doesn't take long to ruin the ac heating element if plugged into shore power, and that switch was on. Nor is it a big problem to replace, and not very expensive either.
But it should still operate in the propane mode. Tell us more about what it does and doesn't do. Do you hear any sparking sound, etc ?

The ON/OFF switch (lower left corner outside compartment) is for the Electric Element. IF you did not turn that switch ON when you had no water the electric element will be OK.



The Switch inside 5vr is for the propane side. IF you turned it ON when you had no water......the propane probably fired off BUT tripped due to tank getting hot.

The RED light is a fault light....telling you that a trip has occurred and you need to reset.



Turn all switches OFF, in outside compartment above gas valve is a rubber cover with 'Push to Reset' buttons on cover.
Push them.......they reset high temp t-stats
Left side is for electric element & right side is for propane (if tripped you will feel them reset)



Water heater tank bypass valve closed...water in WH tank THEN turn on to heat

Good luck!


Wow!!! Old Biscuit you took the time to prepare an outstanding, detailed reply. Nicely done !!

I believe we may have had the electric switch on, will it hurt it, how long does it take to hurt the heater if the electric is on without water?
