Q: How can this be a 3200 PSI pressure washer if the cat pump that it comes with is only rated for 2850 PSI?

MODEL 4DNX25GSI
Flow...............................................2.5 gpm (9.5 lpm)
Maximum Discharge Pressure... 2850 psi (196 bar)
Maximum RPM........................3450 rpm (3450 rpm)
Stroke..............................................0.268” (6.8 mm)

by Will from Wyoming on July 06, 2016

A: That is a very good question- and I've sent 2 emails to Simpson asking about this and haven't heard back from them yet.

There are industry (Pressure Washer Manufacturer Association Standards for rating pressure washers, but they are entirely voluntary and not widely used at this time.

Usually with questions like this one of the variables have been changed during the bench test of the unit- for instance, a higher RPM motor will increase the performance of the pump over what the pump manufacturer publishes.

You may want to contact Simpson directly at 877-362-4271 to see what their tech staff says about their rating.

Q: You said this unit has a cat 4ppx pump. Although this might be true, no such pump exists on the cat web-site. Why? Are you sure this isnt a 4DNX series pump? If so, please identify the whole model number of 4DNX. Thanks.
by David from Iowa on July 05, 2016

A: I apologize for my typo. Pump is the CAT 4DNX25GSI.
by Brian, Product Expert
Q: Please identify the Cat pump model # that is on this unit. Thanks.
by David from Iowa on July 05, 2016

A: This pressure washer utilizes the CAT 4DNX25GSI.

Q: How to heck pump oil
by Dean from Michigan on March 17, 2016

A: There will be a sight glass on the front of the pump. This will be a clear window where you will see the yellow-ish color oil sitting. There is a red dot in the center of this sight glass. The oil should be at that red dot, not over or under. Figure 12, page 17 of the attached Owner's Manual will show and describe this as well.

Q: Want to get the proper extension cord to use. What gauge is this unit?

by Cindy from Michigan on June 19, 2015

A: The unit is a gas model and not ran with an extension cord.

Q: The question I submitted yesterday was about the Simpson ALH3228-S power washer. I was wanting the capability to dial down the pressure for some work at my house. So, would I need another tip/wand to achieve that with this model and if so where would I find that?
by Paul Crowe from Oregon on June 18, 2015

A: I would recommend pairing it with the Simpson Dial-N-Wash model 82235. This unit will allow you to adjust the pressure from the gun between 1000PSI and the full 3200 PSI I have attached a link for you to view that item.

Mv Copasetic's Pressure Washer Purchase
Ordered the unit and it took two weeks for delivery. Customer service through PED was good. The unit was delivered in good order but would not start. The CEO of PED told us to take to a Certified Honda service dealer in Ft Lauderdale for warranty. Simpson was contacted and made aware of the situation.

Honda baulked at repairing as they blamed us for using bad fuel. With continued phone calls Simpson paid for the repairs so we could get our machine back. This was about 10 days later.

Poorly Assembled Frame!
Not sure if all of these washers are like this, but when I assembled the unit, I noticed that the frame was very, very bent. This was not due to shipping. It was due to faulty assembly of the frame and the base plate. See the pic below. I hope PWD will be able to help me out. I'm in a holding pattern now, as I haven't put in oil or gas into the engine.... I'm hopeful this will be straightened out quickly!

Bryan,
I'm sorry your frame isn't level. I checked your file and see we offered you 3 options to resolve this on 6/27 and you chose "We can get Simpson to send you a replacement frame so you can switch everything over" also on 6/27.

We will let the folks at Simpson know to ship out a replacement frame, and we'll email the tracking number of the frame shipment to you through your account.

We appreciate your business and apologize for any inconvenience.

A Powerful & Mighty Washer
Great pro or prosumer washer - i have owned a few power washers and this one is by far the best -worked extremely well.

Only negative is it can be trick to start and not sure why but eventually it starts and runs great.
Pros: Light Weight, Durable, High Quality, I'd Buy It Again
Cons: Hard To Start

Rick,
On direct-drive models like this it's a good idea to squeeze the trigger and let the water run through the unit for a minute or two, every time before trying to start the engine. This moves any air out of the pump and lets the engine turn over.

Once the engine has been warmed up you may also want to check and make sure you've turned the Choke off before re-starting.

Hard To Start!!!
Once you get this thing started it works fine. It is very hard to start.

Jim,
Please make sure that you are squeezing the spray gun trigger and letting the water run for a minute or two each time before you try to start the engine.

This drives all the air out of the pump, allowing the engine to turn over more easily. It prevents what's called 'vapor lock' since the engine and the pump are directly connected.

Time Will Tell
Purchased this unit after having a box store unit fail after 2 years. Arrived quickly and set up was easy.

System would not start out of the box after following MF instructions. It was very difficult to pull (not bc of build up water pressure) It was due to the pump restricting the motor. I took the pump off, start the motor, (started 1st pull w.o the pump on) let the engine warm up, then put the pump back on and tried starting again. Worked well after that,

Still when cold it's... more

About The Best Buy For The Money
Got it on sale for $665ish. With a Honda GX and Cat triplex pump this is about the best entry level commercial combo you can buy. I wish it had a longer hose. Definitely will need to upgrade to a 50 foot hose. The cart seems ok. The thing is much smaller and shorter than in the picture. This is good, because I'm running out of storage space. I bought this over the Pressure Pro model because of two important things:

1. The Pressure Pro uses a custom Cat pump made exclusively for... more

Not As Happy As I Should Be!
For the money I thought I was getting a very premium pressure washer. I think maybe I did but maybe I just got a dud or one that had a rough time in the shipping process. First off, when it arrived I noticed that when UPS man had the box on his dolly sideways, instead of right side up. I hoped it wouldn't be a big deal and when I opened the box everything seemed to be ok.

Upon assembly I noticed when securing the handle that the screws and plastic nuts had a hard time going together as... more
