What position is my hot water cut-off valve in? Closed or open?

It doesn't 'by-pass' the water heater?🥴

It does on "Cloudsplitter", or has done for 17 Winterizations.

Yes...I do drain and blow the heater.

Sorry Lary, that was posted while I was writing my post and I didn't see it.

The older trailers, not sure what year it was changed, do have a true bypass albeit using three valves to do it.

You can go outside the trailer and check to see if the pressure relief valve is hot. If that valve or the tank is hot the water heater is working. If the water heater is hot it is probably the mixing valve causing problems.

Heh, my tankless water heater only needs a supply shutoff valve. It’s easy to tell if it’s set wrong...

The original Atwood 6 gallon had and needed the three-valve bypass setup.

Thank you all for your inputs. I moved the yellow switch to OPEN and several hours later when I was back in the AS, there was hot water. I believe my main problem was impatience. To recap: I de-winterized like I always have (successfully) but when water did not immediately get hot, I decided maybe I had screwed up and closed yellow knob and kept trying to heat the water. I think the reason I didn’t fry anything is that I had previously let water sputter and then flow out of all the faucets. IAW the owners’ manual, the sputtering occurs because “the water heater is being filled and air is being pushed out through the lines.” Regardless, thank you again. I travel alone so you all being there in my occasional hours of need is very comforting.

Good advice above.The problem is not clearly marking what the different valves do, for the non mechanical owners.My advice would be operating valves, with another person turning water at a sink on and off.Also, you must be very careful to make sure hot water heater is full of water, before energizing the hearing element.The element is a $10 part at Home Depot for my late 70s Landyacht.Having a couple spares is good idea, they seem to have a couple year life if used full time.
