Q: Mike: I'm interested in purchasing the Simpson PS4240S. I will however be moving to Australia in 6 months time and I was wondering how to handle any warranty / service issues that might arise. Thanks in advance. Andrew
by Andrew from California on January 23, 2016

A: Thanks for your inquiry. Unfortunately, the Warranty is handled directly through Simpson and is only honored inside the U.S. IO would recommend reaching out to the folks at Simpson to see if there are any options. They can be reached at 800-710-7499. Thanks

Great Power
Advanced high power pressure washer for DIY homeowner. Super powerful- elevates the 21" floor cleaner tool up off the ground.

Worth the extra money for the power.

Not As Good As They Used To Be...
I bought two of these pressure washers. Both worked great for the first two months. Both lost high pressure around the same time and it seems the pressure release valve both broke or the pumps went out already. Also both hoses have burst and gun started leaking.

I have asked for help PED but all they say is call this 1800 number for help and they will find a service center for you. They offered no solutions for help. I don't have time to drop off and leave pressure washers for days or... more

Product Expert
Chris,
This unit comes with a 1 year, consumer-use Factory Warranty from Simpson that covers defects in materials and/or workmanship, but there are longer warranties on the engine (3 years warranted by Honda) and the pump (2 years warranted by AAA- also made by Simpson).

We don't handle parts or service, which is why we referred you to Simpson at 877-362-4271. If you have an engine problem you can find Honda small engine service in your area with Honda's Service Locator. A call to Simpson will be the fastest way to figure out if the unit needs to be taken for service.

I understand your time constraints. If there are multiple repair locations in your area, calling around to see who can get your repair in and out in the shortest time would be a good plan.

Hoses are considered wear & tear items, and are only covered for 30 days for problems in materials & workmanship. Pulling the hose across rough surfaces or for long distances can cause premature failure, as can allowing the hose to kink under pressure or come in contact with the hot engine muffler- those situations would not be covered by a Factory Warranty.

$3.00 Chinese Junk Parts Ruin The Enjoyment Of This Machine
The pressure washer itself - excellent. Engine - hardworking and very dependable.

The issue. The Chinese quick disconnects rust and clog the tips, they are also a royal pain in the ass to disconnect, you'd think the manufacturer would spend an extra couple of bucks on these Chinese pieces of junk.

Great Product
The pressure is awesome. It is very user friendly, nozzles are within hand's reach when using, which makes it very easy to change the nozzles while washing.

The pressure makes it so much faster to clean livestock trailers. Use it to clean equipment and vehicles. Definitely need to use the appropriate nozzle for the job. If afraid of to much pressure can idle the engine down or move away from whatever you are washing a little bit. It is awesome!!

It is a little hard to pull the... more
Pros: Exceeded Expectations, I'd Buy It Again, Easy To Use, Easy To Store

Theresa,
The siphon system to suck detergent will only work with the low pressure, black nozzle- that's the way it's designed. If you need to apply soap at higher pressure you can add a Foamer or a set of 2nd Story Nozzles- just make sure you base your selection on your machine's GPM and PSI.

You will find it easier to pull the rope if, before you try to start the engine, you squeeze the trigger gun and let water run through your wand for a minute or two. This drives out all the air from your pump & prevents vapor lock. (Page 6 in the Owner's Manual.) Since the pump and engine are connected directly, air in the pump can make the engine very hard to pull-start.

What A Work Horse
Saved up for 3 years to buy a power washer like this and it was worth every penny. Cleans my pool deck in about 1/5th the time I did with my old pressure washer.

Great quality.

This Things A Beast!!
Absolutely love my new Simpson pressure washer. The 4200 PSI have cut down my cleaning times considerably. The longer wand keeps you from having to stoop over while washing. The 4 gpm flow allows you to easily wash away any dirt or grime you have blasted up. Always starts on the first or second pull. I totally recommend this washer!!!
Pros: High Quality, I'd Buy It Again, Exceeded Expectations, Price

Totally impressed with my new Simpson PowerShot. Started first pull. Startled by the "kick" of the wand. Like a small shotgun. Cleaned my dirty patio in no time. This is a pressure washer.

Be Careful Where You Point It
It is awesome!! We bought it primarily to clean sidewalks and bleachers at the baseball park and it gets the job done.

However, be careful where you point - at 4200 psi, it will take the paint off a painted concrete wall if you get the wand head too close!!

Happy So Far
Happy so far. I had one problem right out of the box, but it was an easy fix. The ferrule on the high pressure hose hadn't been crimped, so the 4500 psi hose shot right off the barbed fitting as soon as I had a little pressure. Took the hose over to Parker fittings, and they fixed me up. Better than new, I think.

Anyway, did everything by the book - good oil, good gas, fuel additive for ethanol, etc. I learned not to try and start the motor when the pressure is up - felt like... more
Pros: High Quality, Durable, I'd Buy It Again, The 4.5k psi hose od is smaller than than mos 3K hoses I've seen
Cons: Th H2O hose connector is nested close to the frame member, The 4500 psi hose is kind of rigid making it hard to coil
