@@ziptiekustoms That’s great!! And also hilarious! Sorry my video is so old. Funny fact; apparently Aqua Hot points people to this video for help. 😎 lol Glad it’s useful!!
I just replaced my thermostat today after watching your video. It was a piece of cake and it took me all of about 20 minutes to complete. One thing that saved me a lot of time and aggravation was using a 7/8 ratcheting open end wrench rather than a socket. I slipped the wire leads through the hole and had the thermostat out and replace in about 2 minutes. Thanks very much for your video.
Thank you for your Aqua-Hot replacement video. It is very helpful. I have had 3 control thermostats replaced in my Aqua-Hot 250D, all under warranty If I have to replace anymore control thermostats I will be doing it myself. In the Aqua-Hot service manual describing how to replace the control thermostat, it states to clamp off the top back left and top front right hoses before draining the fluid and before replacing the control thermostat. It appears in your video you did not do that. I just want to make sure that is the case - that i do not have to clamp the hoses. My hoses are Pex tubing which means I cannot clamp. FWIW, compliments to you, I sent a request to Aqua-Hot to ask how to replace the control thermostat and THEY sent me the link to your video!!!!!
Thank you! I just got my Aqua Hot running again after watching this video. More importantly, my wife thanks you because she can once agin enjoy her one hour showers!
Because of the difficultly accessing the thermostat and water lines with a typical type wrench, I have found using a basin wrench very easy to tighten as well as to loosen plumbing hoses.
Thanks for posting, I have a 2021 33TL, and the thermostat went out Sunday. AH sending a replacement, using your video as a guide to replace, safe travels!
I have the parts. Can’t find a 250D service video. I need to do mine now. Hopefully you will get a video of it out soon. I do have one question on this video. When you pumped it back in did you pump it back in the drain or put it back in the bottle a little at the time?
@@Adam-dv1px you need to push it thru the bottom. Once you get fluid in the tank you can just pour the rest in there. If you put it all back in the top you take a chance of air locking the aqua hot or at least that’s what I was told. I haven’t done a filter change or maintenance on it yet but when I do, I’ll put out the video. -Jarrett
Thank you for sharing! I am right down the road from you. I live in Nashville, I own a HR 34rx. Your tips are always helpful. Are you part of our Facebook group.
Hey Jarrett - Found your video while searching for a solution for my aqua hot issue. I actually had a Tiffin technician walk me over the phone the steps for trouble shooting my issue and it was EXACTLY the steps in your video. I have the exact same model (250D) that you do. My question is in regards to the barb fitting that you used for draining the fluid. Do you know by chance the size of the fitting that screwed into the drain port? The control thermostat is in the mail headed my way, so was going to go get that fitting you have. Thanks for taking the time to do this video! It's been very helpful.
I’m trying to remember but I think it was a 1/2 in. I went to the local tractor supply and they have a hole section of sprayer fitting and I think I bought a few different size or I took the plug with me to match it up. Hope this helps Jarrett
how did you pump the Aqua Hot full of fluid at the bottom ? I thought the Aqua Hot had a bolt that had to be unscrewed and when finished screwed back into the lower part of the motorhome ? Did yours have a cutoff switch ? Thanks for the video
They said just to drain the unit itself. You just have to get the fluid below the thermostat. I pushed the fluid back in from the bottom to keep it from air locking.
@ournextadventurejvh what are your thoughts- our burner ignites and we can run hot water anywhere from minutes to hours. We had something fixed twice in the past (mixing valve and ?). The green light on “burner” just turns off. Have you had this happen where it works sometimes and sometimes doesn’t? Thanks!
I’m really not sure. But I’d use my multi meter and look for a short somewhere. I’d also be checking all my connections for some sort of corrosion. That would be where I start and maybe find a good aqua hot technician and ask as many questions as they’ll answer. I’m definitely not an expert, would take it to get looked at. Safe travels Jarrett
Aren’t there multiple thermostats in the system? I think I have a bad ELE-015 control thermostat. Have to reset the diesel function multiple times per day plus blowing white smoke periodically.
It will burn you most likely. The thermostat is to limit the water temperature. I would think if you bypass the thermostat it would run and run and boil the fluid out of the system and burn it up. All I know I was told not to do that. Jarrett

I’ve spent hours diagnosing my bosses camper and went to my last resort of TH-cam, you fixed the hot water heater! Thanks!!

great info, I just used the 10A fuse to prove that I need a new thermostat and avoid taking it to a dealer...

Sorry yours went out! Hope the video is helpful! You’ll have to let us know how it goes.
Nice job and thank you.
Awesome video, same thing just happened to me this morning. This video helped trouble shoot the issue.
Oh good! So glad it was helpful!! Not too big of a deal to fix!
Great Video. Appreciate it. You rock!
Great Job!!! You are very informative thanks!
Thanks man, you’re welcome! Hope it was helpful!
Any chance we can get you to film the annual maintenance of nozzle replacement and filter change? We like your videos!
Thanks, we can certainly try!

@@OurNextAdventurejvh thank you. When you say push it through the bottom you mean the drain right?
@@Adam-dv1px
Yes, push it through the drain
Not sure if you turned on the aquahot or it was your Boeing 747 ready to take off 😂 good information, thanks
We get asked all the time what is that noise…. I agree it sounds like
a jet starting up.

@@OurNextAdventurejvh Thank you sir!
how did you pump the Aqua Hot full of fluid at the bottom ? I thought the Aqua Hot had a bolt that had
to be unscrewed and when finished screwed back into the lower part of the motorhome ? Did
yours have a cutoff switch ? Thanks for the video
Good job, how did you keep fluid from draining out of the zones when you drained the tank, Thanks.
They said just to drain the unit itself. You just have to get the fluid below the thermostat. I pushed the fluid back in from the bottom to keep it from air locking.
Happen to have the part number for the thermostat? Seems like one might want one on hand since this seems to be a common failure.
Here is a year later and we need to find out the part number as well… Do you happen to have it?

On mine I only had the one thermostat. I’m not sure on other models. If it’s blowing white smoke it’s probably due for a service..
What if I just leave the fuse ? Instead of getting a new thermostat?
It will burn you most likely. The thermostat is to limit the water temperature. I would think if you bypass the thermostat it would run and run and boil the fluid out of the system and burn it up. All I know I was told not to do that. Jarrett
Mine isn't Circulating the antifreeze to heat the R.V
I would start checking fuses. Make sure the pump is getting power. But in all honesty we never had that issue.
Brand new why would a thermostat go bad so early on very few trips
The Aqua repair guy said they had a bad run of parts. IDK it wasn’t too awful to fix. Just part of working out the kinks in a new RV.
