No hot water!

2012 Rockwood ultra lite
I can only get luke warm water...in the winterized position.
I've opened the release valve to insure there is water in water heater.
I've opened the propane tanks (and can cook). I've turned the rocker switch to on on the water heater. I've turned the water heater on switch to on in the camper and the reset light never comes on...I've pushed the reset buttons on the heater itself. What in the world is wrong. If propane doesn't work, shouldn't the electricity?

If you have an outside shower, is the shower turned off by the knobs or the pushbutton on the shower head? If by the pushbutton, this would allow the cold water to mix with the hot water causing it to be luke warm.

If the third photo is what your valve positions are, then the middle one is wrong. That one should be perpendicular to the PEX tubing. Flip the one in the middle 90 degrees.

He's right. Close the middle valve, open the other two.

Yes, I took the picture before fixing it. I closed the middle valve.
I've also checked outside shower.
I've done so much from endless googling and still just luke warm....

Explain to me - can I select electric only? I'm at a campground!
My old camper, I only ever flipped that rocker switch right on the heater.
Never used winterize on heater cause we do the blow out lines and put antifreeze in traps.
I just got this camper last summer and have never had hot water.
Do I not consider a bad element if it's luke warm?

On our interior control panel, there is an On/Off switch for gas and an On/Off switch for electric for the hot water. You can put either or both on at the same time. If you have shore power, you can use electric only and save the gas. If you do not have shore power, you can only use the gas setting. You can use both together during showering to speed up re-heating time.

If your hot water heater is working, you should hear it working - which sounds different between the electric (which may sound like a high pitched hum, WHEN HEATING) and the gas (which will sound like your gas water heater at home or a small furnace due to the gas flame, WHEN HEATING). When the water is fully hot, neither will be on nor will they be heart.

Working very carefully so as not to get burned, if your water heater is on and working, the water in the tank should obviously be hot and you can confirm this but allowing some water out of the overflow valve - again do this very carefully. If the water is not hot in the heater tank, that's one issue. If it's hot in the tank and not coming out hot at the faucets, that's a different issue.

Also confirm that your battery power master switch is on. If it's on, you will be able to use the interior lights and stereo.

Please report back what you find.

Also, be aware that the valves you have are CRAP. Examine them closely. It's possible you turned the handle, but the valve ball itself did not turn.

I replaced 2 of the 3 in the 3 years I had my Roo 19.

You have a Suburban brand water heater. We have a very detailed explanation on the operation of in the FAQ link below, including the bypass/crossover valves settings in post #3 of the link:

Suburban's electric switch and much more

BTW: You do NOT want the bypass/crossover valves in the winterized position, You want them in the normal/summer use position in order to get water from your water heater. The winterized position is when you drain the water heater and add antifreeze to the water lines in the winter so nothing freezes up and bursts.

The link above explains this.
