The people at etrailer are great and are very helpful. The water heater came in quickly and was a direct replacement. It seems to be working good. The only negative is that it said it comes with a new outer door but was not in the box. I didn’t call them back because I was planning on using my old door due to the paint color. That is the only reason I gave it 4 instead of 5 stars



by:

I gave a 3 since both items were to be rated together. The water heater would have received a 4 and the door kit a 2. Reason is the door corner was bent and paint cracked on a corner. Chose not to send back and wait since the water heater was installed, needed to get the front covered. Package did not look dented, but guess it could have been dropped by the shipper.



by:

Easy installation, works great.



by:

We have Hot Water ! We live in our RV full time so we needed a Hot Water Heater of good quality. Time will tell if this Dometic Hot Water Heater is as good as the old Atwood which it replaced. The packaging was good ! Hot Water Heater appears to be well made. No problems installing the directions were clear and it fired right up. This replacement Hot Water Heater is smaller than our original so we purchased the enlarged door kit which fit perfectly. Great communication with etrailer which helped us find the correct Water Heater for our application. There website information was accurate and we had no problem contacting a human voice when needed.. We are Happy Campers !

Easy installation! Works great!



by:

Needed a water heater and this was the best one to fit, after reading the directions front to back it took only a couple hours total to get it in my RV. Water heated up immediately and everything has run great, of course it's only been a few days but so far so good, my only issue is that there is a back order on the door cover.. so it's totally exposed to any elements and I have put temporarily back on the door that came with the RV ( even though it doesn't fit) it's just so it's not totally a open hole to the outside, hoping it is available sooner than later.



by:

Installation was easy, I did have to raise cabinet drawer up about 1 inch to allow clearance at the back for the water connections. It is quieter than my older (2000) Dometic and hot water recovery is a little faster.



by:

My water heater leaked and It was the old style that is no longer available. This one needed some conversion but it fit. I even made a pan to go under it in case it leaked again.
I used two 1/2” supply lines to make the connections because they were in different locations. Worked like a champ!
Had to use the door conversion which fit perfect.



by:

Thanks great item every thing worked out



by:

It's been one year since we replaced the water heater in my 2006 Jayco Feather and there are no complaints. The new water heater is working great and etrailer was a huge help when I purchased it. If you're replacing a water heater, I would read the Question and Answer section on here for the model you are going to buy. And also pay close attention and figure out if your current water heater door will work with the new water heater. They may vent in different places.



by:

Arrived a day early... GREAT!!! MFG packaging brought the rating to a 4. The mounting flange was bent on 3 of the 4 sides, due to no additional packing inside the mgr box. The flange was easily bent back into shape.
Install was straight forward, per mfg instructions.



by:

i had to replace my Atwood Water Heater again thanks to the extremely HIGH calcium content in the water where i was living in Northern California. This NEW water heater was a simple install. Everything fit perfectly and i had it going in about 2 hours. NO complaints what so ever. it works Great.



by:

The purchasing and shipping process for etrailer was amazing. I made this purchase over a weekend to have it arrive on a Wednesday as the website indicated. There was a problem processing a payment and I was contacted several times by Andy to ensure the problem was rectified and the heater was shipped in a timely fashion. My water heater arrived a day earlier than they estimated on top of the processing issues and once it was delivered, I received an email confirmation which also included a link to documents related to the installation process

I only had two minor issues with the heater, but they do not negatively affect etrailer.com. It arrived with mounting options for the front door on the top corners instead of with the center tab as indicated in the pictures and also how my previous heater was setup. I thought it was going to be an issue as I didn’t purchase a new door, but I just moved one mount to the center position.

Second, this water heater did not come with any mounting screws. I’m sure that’s Dometic’s choice and I was able to reuse my old hardware. So just a heads up for anyone in the future.

Overall, thank you etrailer.com, everything worked out great!
The install process was easy and it’s working better than my old heater ever did.



by:

Propane works great! The electric side not as hot water easy install, yeah right. Takes knowledge to install, which I have , the rerouted propane line was a challenge, under carriage to redo line and flare fittings , also a better description of wiring of gas and electric low voltage, I went with colors to match but didn’t want to damage unit



by:

Water heater was delivered yesterday. I just installed it for a customer this morning. Everything went smoothly. Tested the water heater before finishing sealing up the outside flange with butyl and screws. Heater was working great on both propane and electric. No leaks the customer was very happy to have it working again.



by:

Kelly at eTrailer is great! We run a small but very busy RV repair business and love all our friends at eTrailer. The parts come quick and are fantastic quality!



by:

Exactly what I ordered and it was plug and play. Delivered in 3 days which was a plus. Thank you



by:

I'm giving this 4 stars, because The water heater and door kit work to replace my leaky Atwood water heater. By comparison, this beats the Atwood by a large margin. The drain cap is very easy to get to, for winterizing.
Now, I held back the 5th star only because I've had to redo the plumbing. I know, that would have been asking too much, but I also would have gone with 5 stars, if the color of the door matched my RV. *wink*



by:

As always with ETrailer, we received great assistance and accurate information. The water heater took a couple of hours to install as a couple of adjustments needed to be made to get it into the space. We are up and running again thanks to ETrailer and Andy!

This water heater was meant to replace an older Dometic model which was heavier and had a larger opening. We appreciate the new style and feel it works well. We had to buy a door conversion kit. E-Trailer was wonderful in getting it shipped in a prompt fashion. We have just a few recommendations for Dometic for this model. 1. Please provide a silver colored door conversion kit for Airstreamers. We ended up painting it with a high heat silver spray paint. Just added unnecessary steps to the install. 2. Please provide self-tapping screws for the actual unit to be put back in place. Our older model had 10 screws and we used them all, and then some. So, we ended up halfway thru the install only to find out we were missing 10 screws. None of the holes in the new frame lined up with the old model. Also, a bit annoying. It would be great to include electrical connectors to snap the wires together and include a low profile outlet to plug the new model into. We were able to cobble things together from Home Depot, Lowes, Menards...but it would be even better if these items were offered or suggested by e-Trailer during the purchase. And we can add Butyl tape to that list. 3. We also wish the door conversion kit was a bit more seamless. We screwed in the corner supports on the water heater, only to find out we needed to take them back out and use the door kit corners. Again, the product is better but the devil is in the details. Glad this project is done.

Easy install, great directions and reliable equipment. Extra shout out to etrailer.com for helping me get it much faster since what I ordered at first wasn't immediately available.

  • Replacing an Atwood GC6AA-10E gas/electric RV Water Heater
    Hey Jeremy, thanks for reaching out! The best replacement for your Atwood GC6AA-10E gas/electric water heater would be part # DMC33RR with a black door or part # DMC53RR if you want a white door instead. It’s a great match and will work well in place of your original unit. These water heaters need a cut out of 12-3/4" tall x 12-3/4" wide x 19-7/8" deep. What kind of camper do you have?

  • Troubleshooting Dometic RV Water Heater Producing Water That Is To Hot

There is a chance it could be a faulty thermostat or that thermal cut off fuse is blown. The cut off fuse is locate near the thermostat and you can test that with a multimeter to insure that is is working correctly.

  • Looking For Water Heater To Replace Suburban Unit In 2023 Wildwood Heritage Glen 310bhi
    Hello Huston, thanks for reaching out. Were you wanting to go with another tanked water heater, or did you want to go tankless? We have options for both. If you want to stick with the tanked unit, we have the Dometic RV Water Heater # DMC33RR which has a 6 gallon tank. It requires a 12-3/4" tall x 12-3/4" wide x 19-7/8" deep cutout so please make sure this will fit in your space. We also have 10 gallon tank options if you want to go larger. Space limitations in mind. If you want to...

  • Replacement Water Heater for a Atwood GC10A-4E
    Hey Brandon. To replace your GC10A-4E you'll need to use a gas and electric water heater or a gas only. There's no options for an electric only water heater. The Dometic RV Water Heater item # DMC33RR, you were looking at, would work as a replacement size wise. However, it's a standard tanked water heater that only has a 6 gallon tank. You'll actually have less hot water and they don't make 10 gallon ones that fit your cutout. Instead, I recommend upgrading to the Furrion RV Tankless...

  • Troubleshooting E.C Error Code With Fogatti RV Tankless Water Heater
    Sediment build-up may also causing you to continually receive the E.C error code on your Fogatti RV Tankless Water Heater # LSB44FR. Since your unit is pretty new it is unlikely but I would try and rule everything out first before replacing the unit or buying anymore replacement parts. You also might also consider installing a Camco RV and Marine Disposable Water Filter w/ Hose Protector # CAM40043 which will remove aluminum, bacteria, bad taste, cadmium, chlorine, fungus, heavy metals,...

  • Will the Dometic RV Water Heater # DMC33RR Fit in Place of My Suburban SW6DE?
    Hello Robert, Thanks for writing in. If you want to replace your Suburban SW6DE with another tank-style water heater, the Dometic RV Water Heater - 10,000 Btu - Propane/Electric - 6 Gallon Tank - 120V - Black Door # DMC33RR is the one I recommend. Your existing 12-3/4" x 12-3/4" opening is very close to the 12-7/8" x 12-7/8" cutout required for the # DMC33RR. Because the Dometic requires an opening that is 1/8" larger in both height and width, I cannot guarantee it will fit your current...

  • Replacement Water Heater for Atwood G6A-3
    Hi Devon; all of the Atwood G6A models are 6 gallon water heaters with some slight variation within the models which is why you see the Dometic # DMC74FR (Gas/Electric) or # DMC39RR (Gas only) recommended as the replacement. The same is true for your G6A-3. I don't have a lot of information on the G6A-3 but I would choose a replacement based on whether your current model is gas or gas/electric. You also want to check your current cutout. If you have a 16-1/2" wide cutout you want the...

  • Recommended Replacement for Atwood GC6AA-10E Water Heater
    Hey Kurt, hate to hear that happened. I checked the model number you provided and there isn’t a true direct drop-in replacement for the Atwood GC6AA-10E anymore because those units have been discontinued. The closest option is a Dometic 6-gallon gas/electric water heater # DMC33RR, which matches your propane and electric operation. The Dometic water heater is 12 ¾” x 12 ¾” compared to the Atwood being 16” x 12 ½”. So, it will physically fit in the space, but it won’t fill the original...

  • Can Tankless Water Heater Replace Water Heater With Tank
    Hey Brian! You can definitely replace your existing water heater with a tankless water heater. I recommend the Furrion RV Tankless Water Heater as a replacement. This will use your existing gas and plumbing lines so the only thing you need to do is measure your cutout. The Furrion requires a 12-3/4" to 12-13/16" wide x 12-5/8" to 12-3/4" high x 23-1/2" deep cutout for installation. You can choose from the following based on door color/size: -Furrion RV Tankless Water Heater - Gas - Auto...

  • Can Dometic RV Water Heater Replace Atwood GCH6A-10ES Without Modification
    Hey Tori! Yes, the Dometic RV Water Heater # DMC33RR will directly replace your GCH6A-10ES without modification. This water heater is slightly smaller at 12-3/4" tall x 12-3/4" wide x 19-7/8" deep so it will fit the existing cutout without any issues. As for the door, you won’t be reusing the old one. This unit comes with a new door and a conversion kit that’s made to fit the 16-1/2" wide opening from your current setup, so everything will line up clean and look right once it’s installed. What...
