Just back from the mountains and de winterizing my 2015 Silverback with Surburban water heater.

I "thought" that I waited until tank was full and tested by tug on pressure relief valve BEFOREHAND flipping electric switch.

To accelerate heat of water, I flipped DSI switch, red light came on. Heard it trying to ignite so I was distracted and moved on to other projects. After 20 minutes, no hot water! Went to cabinet: DSI light was out. Went outside felt tank: cold.

So, any experience and advice will be appreciated and tried this weekend.
Thanks in advance for anticipated comments.

I did bring home my Surburban brochure and will be reading it line by line as well.

So: overall; no hot water.
Electric: ? Any fuses or?? Trip breakers??
Gas: no ignition.

You make sure your gas was on, try to light your stove to check your lp

The DSI will only try 3 or 4 times and then shut down, just turn the switch off and back on. Light your stove burners and purge the air out of the lines also.

Couple thoughts: If you have three valves, are you sure the hot water outlet valve is open. If you have the cold water inlet valve open to the water heater, it will allow water into the heater like it's supposed to especially if the bypass valve is also still open, but you won't get hot water out if the outlet valve is closed. I would flip the pressure relief valve up again to get water out, and see if its hot. If so, then you may have valves set incorrect. You said the tank was cold, so this is probably not the cause, but won't hurt to check. I would check all 3 valves again for correct position.

If the gas failed to light after 3 attempts, then the system goes into lockout mode. You have to turn off the DSI switch, then back on again to reset the lockout. Are you sure you have propane, and the tanks are open. You might want to burn the stove for a little to purge excess air out of the propane lines first.......especially if it's been in storage for awhile.

If your DSI light was out? Wouldn't that mean the thermocouple sensed the correct temp? I'm not an expert but I'm thinking the electric element would bring it up to temp or the thermocouple sensed proper temp and the propane valve closed as it should. Have you popped the relief on the water heater to test water heater temperature? So... yea recheck the valve alignment on the water heater.

Not SURE why the DSI light went out. But, the pressure relief had water and it was luke warm, not hot! I am thinking the electric came on and tripped off for some reason. DSI may never have ignited to begin with. Was in storage for 3 months at dealer. One tank was empty and the other was open and 3/4 full of propane. I will try to light the STOVE and see if I have gas flow. 2nd, I will see if I have an electric breaker popped someplace.
Thanks for the input. Was going up tomorrow, but, N Georgia has severe storm warning!! That's why we have insurance.
Our R Ranch had a tornado 20 years ago, 1 death and total clubhouse destruction. I ain't stay'n in no RV if I am not boxed in with no alternative place better, like AWAY, FAR AWAY!!
I may be old, but with age comes experiences, mostly good!! 😊

DSI will try 3 times and go off and it has to be turned off and then on again and then it will try 3 more times and go off. It will just keep repeating that sequence until it starts the burner.

Luke warm water is usually an indicator that the valves on the water heater are not in the correct position. It sounds like you have cold water mixing with the hot water. The valves should look like the first pic.

Tnx for the diagram. Hard to tell when whacking your head behind the panel.
They should furnish helmets with every RV. I am sure after 5 years of fifth wheels and every one of them different, walking into the hitch, raising up too soon and just blindly walking into the side of the RV without stooping, should have concern for being early disabled!
I do frequently NOW wear a bicycle helmet when working outdoors on the RV.

Old Coot....tnx for the 3 strikes and reset tip.

Between all of this AND using a surge unit for the first time, I will get it handled. Live and learn.

I hear you about head whacking and fifth wheels SilverbackMel. Iíve done quite a bit of that myself LOL.

Iím sure you have the same birdís nest of electrical wires, hydraulic lines, and plumbing by the water heater like I have in my Silverback. Accessing the valves on the back of the water heater can be quite a challenge for this old man.

Here are a couple of pics. When you slide the access panel out of the way you are greeted with this. The water heater can barely be seen.

Hereís a photo of the three valves on the back of the water heater. The bottom one is a bear (Silverback) to reach.
