Customer Questions & Answers

What brand pump is on the unit?

What brand of pump is included with this washer? Spec section just says "other". Does this pump have ceramic plungers?
Asked by: Jerry61
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.

What is the minimum input GPM?

I plan on using this with a 100GL water tank. What type of input pressure is required? Does HD have a pump that they recommend for this? Thanks
Asked by: gerry
Same as the output 3.5 GPM. Water is not compressible. As to pressure, about 15 psi is sufficient.

How will thiis unit perform while washing buses, will it take bugs off of the front grill?

Asked by: ere0165
This machine will take the paint off the bus along with the bugs. The pressure on this machine is equivalent to what is used in some car washes. I would not recommend using the yellow or red tip when cleaning if you are in close proximity.

Can the pressure be varied on this washer, or is it fixed at 3800 PSI?

Asked by: washman
It is set at the factory, but you can lower it by slowing the engine down.

Rated 1 out of 5 by from 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.

The gas tank on board holds enough gas to clean a moderate sized driveway. If you have a large driveway you may need to refuel at the midway mark. The hose provided is long enough for most applications. I bought an additional 50' hose to connect to it and I did not have to move the pressure washer during the entire cleaning process. The different heads on the machine work great. when you switch to the soap head it will automatically draw soap into the hose and dispense. The only negative to this machine is the trigger. The trigger does not have a lock to keep it in place while cleaning. This prevents you from being able to move the water into needed positions easily. Overall it is well worth the price.

Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from Great Pressure Washer I've had this pressure washer for a little over a month now and have used it several times. I've owned other pressure washers in the past, but this is the most powerful one that I've ever used. I was tempted to buy a turbo nozzle when I purchased the washer, but now after using it, I can see that I don't need it. This pressure washer has enough pressure to tackle any cleaning job without the need of a turbo nozzle, which I did need for other washers that I have owned. So far I have not had any problems out of it and I hope it continues that way as I've read some negative reviews about the pump. Never let the pump run without water flowing through it and never disengage the trigger over a few seconds while in use. I've seen people stop and do other things while using a pressure washer while the washer continued to run. This is a sure way to burn your pump up. Also take the time to relieve all of the air out of the water hose and pressure hose before starting it. I use this pressure washer with a 3/4 ID contractor grade hose. A 3/4 hose will allow more water flow than a 5/8 will. It is important to get the most water flow that you can to a pressure washer, particularly one of this capacity.

Rated 1 out of 5 by from Dewalt power washer Even though in the past dewalt has performed very well, this time however was not that way, after waiting to receive my power washer, I followed the direction as always and tried to fire this beast (I thought) and to no luck it would not start.... took it back and received a full refund and as of right now have not purchased a replacement.
