Unexplained shut downs

I bought this last week and I'm pleased with how easily it starts. It works really well with my 16" driveway attachment. The engine does seem to be overloaded when I use the 25 degree tip(the only one I've used so far). The one complaint I have is the engine seems to " flood out" for no reason. Oil level is good and I'm using fresh ethenol free gas. I suspect it has something to do with the vapor recovery system on the fuel tank but I'm not sure. Still investigating.

A great product and value. Fast delivery too.

I've been pressure washing for decades. The WPX3400 pressure washer is the best unit I've owned and used. While pressure washers are basically the same design, the Westinghouse WPX3400 is an outstanding machine, performs great and is more than enough power for my needs. I'd recommend this unit every time!

Value and performance.

Quality of unit. Clear simple assembly and startup instructions. Plenty of power. Perfect for my large property with lots of concrete and Northwest mildew and moss. The only improvement I can think of would be a more flexible wand hose. It’s pretty stiff compared to others but does get the job done.

Oil

Unboxed and put together the pressure washer. Made sure to ensure oil was at the proper level and checked all connections. First use, pressure washer worked great, until I noticed oil pooling on my deck. Turned the unit off, let the unit sit, and again checked the dip stick, still at the proper levels. Checked the dip stick gasket and the fill gasket, both looked good. I will be filling out a warranty submission now, and will update depending on the service received.

Great product

I bought the WPX3400 pressure washer about a month ago because it was voted the best “overall” pressure washer for residential. It works great and it is very powerful. I was impressed by how it lifted up and washed away dark wood stain from my cement. The only draw back for me is where the hose attachment is. It connects right next to the carburetor that gets very hot and the hose had been touching it while in use and it burned the hose that I wouldn't think is part of any warranty. Now we have a hose zip tied to the handle to prevent it from happening again-

Need to address the hose connection direction

I liked everything EXCEPT the way the hose attaches to the back. Our brand new hose is almost rubbed through from the friction because the back side goes straight towards the tires. We used it 1x. And hoses are expensive. Other than that...great machine. Our NW side of house looks like it did when we sided it 5 yrs ago

Nightmare

Just took it out of the box and put it together. I followed the instructions to the letter. This is the most difficult power washer I have ever had to start!! I've only gotten it started twice, And had to stop it To take a couple of breaks. I'm on my third start and I'm dying trying to start this thing . I sure wish I hadn't bought this

Verified Purchase

[This review was collected as part of a promotion.] Because it is quality. The machine is powerful and knocks the crud that has built up out of the concrete driveway for the last 10 years. I have the cleanest driveway, sidewalk and bricks on the block. I will have the cleanest house exterior tomorrow. This is a well-built machine. Followed the well written instructions. Pulled the crank 3 times and it fired right up unlike my well-known brand that starts with an H for more money. Very impressed and not disappointed at all. It's a good investment.

Looking forward to many hours of use!

Just purchased, so haven't used it yet. But I made the WPX3400 purchase after a lot of research and reading reviews. I am confident with Westinghouse brand, I have a keeper. If possible I will update the review and star rating at the end of the summer.
