2003 Winnebago Journey DL 34HD Water Heater Bypass Solenoid

[TDServices]

This is for anyone who has a 2003 to 2005 Winnebago journey dl 34hd mine has the electronic water heater bypass and winterization system ( optional on this coach) if anyone does and it’s still original can you please provide pictures of the water closet piping (covered by a white panel ) above the city water fill I need to fine all the routing for water lines as mine is missing one selenoid and the piping is very confusing now and I have looked at all the Winnebago online diagrams I would really appreciate anyone’s help

That looks like the best I can find also and no help. They seem to be doing some work at gradually getting more of the new parts catalog (new system) added but I'm not sure of that being a work in progress or just done. Either way, now would be agreat time to have the older interactive part setup that they have removed. It was great for digging in and being able to turn the view in every direction until we got what we needed. I bleed when I think how much better the old than the new deal on info!
But whining doesn't help, so some looking may/may not help? That looks like about the worst drawingI have seen with way too many open pipe ends shown!
Something you may know as you can see the RV, but I wondered about the confidence of a pipe to the the water tank as well as one FROM it???
I'm more used to seeing one that is used to both fill and use water from the fresh tank?
But I will certainly not say you are wrong, either!
Which brings a thought? What would it do to take a look at a different year to see if it was the same layout but the drawing a bit better? Winn does seem to keep lots of thier products and layout the same for several years and they do have a way of drawing things different even though there was not a change.
Maybe get lucky and find more or different info?

The plumbing for my Swan Industries automatic winterizing system is not nearly as complicated as your picture.
The automatic winterization system Winnebago used was made by Swan Industries, based in St. Louis, MO. New replacement solenoids are sold today but the price is staggering IMO. The system uses 2 12V operated solenoids to re-route water/RV-antifreeze flow and bypass the water heater.
My system still works, but due to the very infrequent use, the valves stick. Nearly every time they stick, I can use the 12V switches in the coach to turn them on/off several times prior to winterizing and they begin working.
I planned last winter to remove them, diisassemble and clean them, but illness prevented that from happening.
I had the operators manual on my computer, which of coursed crashed last winter. I'll have to retrieve it from my W owners briefcase and scan it into this computer when I have time and can remember to do so at the same time.

Thank you guys so much for the help I would like to keep the original switches but that we will have to see but will do more research and there are two pipes going into the water tank

Definite thing, for sure! I am certain to have looked at more where the pipes go to the water pump more direct and not involved with the bypass.
Just another thing that I was confused about whether I knew something?? That's getting to be a long list!

The 2002 Winnebago manual diagrams show the lines in more detail with the connections being kinda obscure I’m trying to get the whole picture working with both diagrams I was hoping somebody still had the original setup and could post pictures of the plumbing lol

 

[Morich]

THAT is one messy drawing! Seems like they missed the concept of using detail drawings to keep the main less messy?
UGH!
Now to find somebody who has the same and also has the panels off to take a few pictures! Double ugh on that thought?
I'm guessing once they've had to look behind that panel they never want to go there again!
I did a check of the owner's manual for anything they might have shown there but it is all from the outside and you need behind the panel.
This is a link to manual in case it is not onhand and might show you better than me:

No help here...

Yea it’s alittle crazy behind that panel they even have the water pump in the electrical side so I actually took that off and mounted it upside down on the shelf below the water housing put the filter so it would still catch debris and I still have a lot more room in the electrical side for stuff and here’s what my water panel looks like the blue marked line was supposed to go to the missing solenoid switch I assume from the drawings

Switches or solenoids? I've replace one of the 12V switches, but did not find one with a light in one direction only, so just marked the face-plate with an O for off and installed a standard on/off rocker switch.
The actual solenoid valves can be disassembled, cleaned. and rebuilt with new O-rings The actual solenoid is nothing special, you can find them on the Digi-Key website; the ID numbers should transpose to a Digi-Key stock number.
Swan used to sell new 12V solenoid valves, but as I said, outragous @ $300 ea. Different brands can be used, but require redoing the plumbing.

The switches both still work and light up I’m assuming I’m missing the selenoid that went to the bypass for the water heater because the other selenoid has the winterization tube hooked up to it and I guess they decided to never fix it because no matter everything I try I can’t bypass the water heater when using city water or running the water pump it always fills the tank first
