It is a Model 10.0 GA13 made by AAA pumps, a Simpson company. It has ceramic pistons.
This pressure washer performs spectacularly!! If you buy this pressure washer, you will get the best power-product engine Honda has ever made (IMHO – and I am a former power-products engineer at American Honda), but it comes with what may be the least-reliable pump ever made, so be ready to buy a spare pump. I have gone through 3 pumps in 9 months even tho I know how to care for pressure washers.
Sadly, the average in-warranty repair time for this pump is 6-10 weeks from ANY repair center except Simpson’s, who gets replacements to their repair centers within a week.

Since I need a pressure washer that actually works every day, I can’t wait 6-10 weeks for a repair, so I bought a spare pump and then helped Simpson set up an authorized repair station near me, as there was not one within 100 miles of Salt Lake City (October 2016).
Replacement pumps installs in 10 minutes or less; just remove 4 bolts, pull the pump off, push the new one on, tighten the four bolts and send the broken pump to a Simpson (not DeWalt) service center.
For out of warranty replacement parts, your best source is Simpson. Call 877-362-4271 to order them. I recommend Dave at extension 8270. He is very proactive and helpful.

I have a more to say about the DeWalt 3800 so look for my review of the support that comes with this product, if Home Depot will post it. If you can't find my review, I will also post it on Google, under Home Depot and under the DeWalt 3800 Pressure Washer, and mention in those reviews that HD would not post my info.
Again, when it is running, this pressure washer performs spectacularly! Be sure to add an inline water filter, available in the pressure washer section at Home Depot. Minor crud in the water will kill ANY pump.
With Simpson’s support, this is a GREAT product. Read Less

Gerry,
Normal water inlet from a metro source is 45 to 65 PSI. GPM is measured by the size of the inlet of your garden hose. Normal 5/8 is 6 GPM but with a 3/4 you can go to 8.

Answer: 
Pressure washers are easier to start if you pull the wand handle-lever to let the water flow while pull starting it. Put the choke full on, squeeze the lever and pull. Honda engines are the easiest to start. BTW, the engine has an oil sensor that will not let it start unless there is oil in it.

Mine has started first pull every time for me EXCEPT when I confused which lever was what. Make sure you have the throttle wide open and the choke on; as well as gas on. Also, if you are putting a gas preservative in the tank, some brands are better than others. I use SeaFoam after having had a non-starting issue with the other leading brand.

Rated 3.9 out of 5 by 100 reviewers.
Rated 1.0 out of 5.0 by They don't post bad reviews I would be very hesitant to purchase this product. I wrote a negative review of this product that was an exact description of my experience with it, and Home Depot simply didn't post it. Long story short, it comes advertised with a 5 year limited pump warranty and 3 year limited engine warranty, but the limitations on the warranty quite literally exclude everything that might happen after 1 year. I left my email, which is my business email, and haven't even heard anything back about the status of my review. October 11, 2016
Rated 1.0 out of 5.0 by This pressure washer truly performs, and performs spectacularly well. It has likely the best engine Honda ever made for power products. Sadly though, the DeWalt 3800 has a well-performing, but most unreliable pump I have ever seen, in 30+ years. I offer this opinion as more than a casual observer; I was formerly employed as an engineer in the power-products division at Honda's US headquarters. So how unreliable is this pump? The pump on the first DeWalt 3800 I bought lasted only 2 months before it failed. After it was out of service for 3 weeks to be repaired, Home Depot did the right thing and replaced the entire pressure washer with a new unit. The second Dewalt 3800 lasted much longer, it worked 4 months before the pump failed. However, this time Home Depot would only refer me to the DeWalt support center, where I took it. After waiting 4 weeks for them to repair it, the DeWalt center still had no idea when I would get it back, so I returned to Home Depot, hoping for them to step up and do the right thing, but this time they did absolutely nothing, even after I had waited four weeks and still getting no promise of when it would be working again. My second 3800 ended up being out of service for 7 weeks. Here is an easy way to quantify this product’s reliability; by comparing the time it was down, to the time it was working. The time down for both my 3800’s was 2.5 months, divided by the 6 months they were working. That number is 41% --they were down 41% of the time. This is called terrible reliability, but far worse is what my local Home Depot did for me – nothing, except to shrug their shoulders. Since I am now stuck with this washer, and since it really does work VERY well -- when it works -- I was motivated to get the second 3800 repaired, so I contacted DeWalt's national support center. They didn't help, because all their pressure washers are manufactured and supported by Simpson. However, they did refer me to Simpson's support center. After calling Simpson and telling my story, they delivered a new pump to the DeWalt-owned and operated service center, where my machine was still languishing, arriving in just days. Apparently the DeWalt repair center did not know how, or where, to get parts, but they do now. And, just so I would not have to re-orchestrate the upcoming next repair, I asked a well-run, local repair center, the Mending Shed, to become a Simpson repair center, and they did. Now they can get Simpson parts to support my DeWalt 3800 in only 2-3 days. Best of all, the Mending Shed is well run -- they say what they do, and do what they say. What a concept. So, DeWalt and Home Depot, do you care about your customers? When it comes to demonstrating that care, you have a huge "upside opportunity." October 26, 2016
Rated 2.0 out of 5.0 by had to return twice Only had this pressure washer for a few weeks and we had to return it twice. It kept breaking. Probably going to try a different brand next time. September 13, 2016
Rated 4.0 out of 5.0 by NICE Product; No complaints. Quality is obvious. I added the picture to prove I actually bought and used the unit I am reviewing. I'm not convinced some of the negative reviews were from people who actually have the machine. #1 THE MOTOR: I tend to over research my purchases prior to buying. In doing so, I decided I wanted to go with a commercial quality Honda engine. Even as a do-it-yourselfer, this is tool I'm going to have for years, and might as well get something good, rather than having to upgrade later. So far this motor is starting on the first or second pull every time, and it pulls very easy. It is much nicer than my neighbor who has a washer with a residential Honda motor, the step up in quality of obvious. The warranty is good. #2 THE PUMP: After researching pumps, I wanted quality, with the idea this is a long term machine for a DIY'er. The pump on this device, with an oil reserve, is a commercial grade pump, with ceramic components and a great warranty. #3 OTHER FACTORS: I was ready to buy the model below this, but in the final comparison I decided I wanted a model with a 36" wand with a side handle to hold onto. I wanted a 50 foot hose. If you buy the next model down (which has the commercial motor and pump) by the time you buy a longer hose and wand, the cost is close enough that you might as well get the next model up and have these nice items, plus you get more power. The warranty on this machine is better than the residential units and impressive. I hope I don't need it. This is a rebadged Simpson unit sold by Dewalt and stocked in most Home Depot stores. You can order the Simpson version from Home Depot as well, but I can't see an advantage unless you like the color combination better. I like items that are stocked in store. If I get a lemon, I'm going to want a replacement right now... The price point is the same, if not better at Home Depot than buying a Simpson elsewhere. #4 POWER: This is the most powerful unit I have used. You need two hands on the wand when you pull the trigger. The motor is working hard, so it would seem you want to buy a machine powered by a reliable and lasting engine. Makes my electric look silly. So far so good with the projects I have put it to work with. With this much power, it takes a quarter of the time my prior electric 1800 PSI unit took, and has the power to do more than the electric is even capable of doing. Hopefully it will provide long term reliability. I don't think Dewalt would but its name on it or offer the warranty it comes with if it wasn't built to last. April 17, 2016
Rated 4.0 out of 5.0 by This is the machine! We use pressure washers to wash ground cover for major concerts. This machine with does the job well. No need for soap, just powerful pressure. Cleans like a dream! August 16, 2016
Rated 5.0 out of 5.0 by Comparison between the dewalt 3800 and 4200 I purchased this 3800 dewalt and loved it however I decided to upgrade to get the 13 horsepower engine that comes with the 4200 psi dewalt pressure washer that was 999.00. I paid 799.00 for this one. So I swapped it out for the upgraded version and it was nice. I didnt notice that much of a difference between the two. Took the 4200 to my first job and it was giving me issues. It was making this terrible squeaky noise over and over again intermittently. And then it wasnt working with I believe the pump. It wouldnt push out any power with the water. Im not sure if its a low quality pump or what. Or maybe just a defective unit. Not sure if I will even find out. My initial thought was to go swap it out but when I went back I saw my 3800 psi that I had returned and decided to buy it back again. My plans are to return the 4200 at this point. At some points we do have a slug here and there with the 3800 where it lags and doesnt push out as much pressure. Maybe they are lower quality pumps. Maybe there not. One pressure washing supply store online told me to make sure PRC isnt written on the pump. Peoples republic of China because its cheap and junk that wont last long. I didnt see that written on the 3800. Worse case scenario if my pump goes out I can just replace for a few hundred bucks and buy a nice one online. Its not hard to swap out anyways. Hope this reviews helps. Also if you buy these units heres a suggestion on a surface cleaner. We ended up liking the BE whirl away 20 inch better than the more expensive Whisper Wash Classic 19 inch 4 nozzle. I may need a more powerful pressure washer to see the whisper wash shine but for now buy the 330$ BE surface cleaner August 21, 2016

Jeeze how hard would this be to do? I am torn as I got great service by some in the store and horrible from others. Less than 24 hours after getting this machine I had to leave it at their service center and believe it or not the demanded that I pay (in advance) $18 to have it checked out! Then added insult to injury by saying that I "may" get that refunded. July 17, 2016
