Pressure Washer Leaking Gas
I used it one time and it started and worked well, but then it started leaking fuel around the float bowl now it won't start and if you tilt it at all gasoline leaks out is there a gasket at the top of the float bowl?

Very frustrating.
Cons: Unreliable

Tommy,
I clicked on our Service Center Locator link at the bottom of our web page, and the closest Authorized Generac Service Center to your town is:

TURF & IRRIGATION HDWE INC
933 Airline Rd
Corpus Christi, TX 78412
361-992-4914

Other locations are available close by if you'd care to check. You may want to call around to see who has the shortest turn-around time.

You will also need to bring a copy of your invoice to the repair shop. I checked our files and didn't find a listing for you, so I'm sorry I can't provide one.

Major Design Flaw
The story is too long to tell about this product and dealings with Generac. This product has a "major" design flaw. . .

To make is simple, the inlet where you connect your water line, extends beyond the back of the unit. It is made of cast aluminum. I attempted to have the unit shipped to my home, the inlet was broken off in the box. I tried to have a replacement delivered to my house, opened the box and the same part was broken in the box..

If you look at this unit you will... more

Very Bad Quality Control
This is what happens when the quality control is bad:

I assembled the unit, and filled the gas tank- SURPRISE- gas all over the garage floor. I didn't see where it was coming from so I took the filter cover off. And guess what? the gas line was shoved back under the gas tank.

I finally got that fixed, then started it up and I can't pull out the choke. I haven't started fixing that problem yet.

The only good thing about the washer it does clean fairly well. The hose is super cheap-... more
Pros: Easy To Use, Light Weight
Cons: Low Quality, Unreliable

Jack,
You shouldn't have to fix anything yourself- this unit comes with a 2 year, consumer use Factory Warranty through Generac.

Just give them a call toll free at (888) 436-3722 x5381 to find the closest locations in your area. Please be sure to have the pressure washer's serial number handy when you call them- they may ask for it.

You can also use the Service Locator link at the bottom of our web site. If several locations are listed we suggest calling around to find out who has the shortest turn-around time. You will need to bring a copy of your invoice with you to the service location.

Good Product
We bought this for general use here at the Condo Association.

Assembly was easy, with well fitting parts and mostly made in the USA.

When assembled. started on the third pull and had good pressure. So far, we are well pleased.

As I Stated In My Last Review, Change That To No Quality Control
In my last review I complained about the gas line not being connected to the carb. And, not being able to pull out the choke because some idiot bent the cable at a 45 degree angle, thus stopping the choke from being pulled out. I fixed both problems.

Now it won't start at all. I have fresh gas and spark to the plug. After pulling the starter rope for about 20 minutes I gave up
and shoved that piece of crap back in the garage and gave up.

I'm 84 years old and in fair shape for my age,... more
Cons: Low Quality, Unreliable, Bad Instructions, As I Have Written Before About The Gas Line Not Being Connrcted A

Jack,
A common reason a pressure washer engine won't start is vapor lock in the pump. Squeeze the spray gun trigger for a minute or so, letting the water run and drive out all the air before you try to start the engine.

If that doesn't help, your unit has a 2 year Factory Warranty through Generac. You can click on this link to go to the Generac Service Locator. Enter your zip code to see the Authorized Service locations in your area.

If there are several with the red tool icon (those have service mechanics), it's a good idea to call around to see which place has the shortest turn-around time. Be sure to bring a copy of your invoice with you, they will need it to file the Warranty paperwork.

Not Working Well
The machine is nice, but I had a problem with it shutting off every time that I moved to cover more area.
Pros: Features, Price, Nice Looking Machine
Cons: Difficult To Use, Bad Instructions, Not Clear On Where Detergent Connection Goes

Ernesto,
Pressure washers use the flow of water to keep the pump cool. If the unit is left on but there is no water flowing it can overheat, so the thermal protection may be shutting the unit off.

This unit has a 2 year Factory Warranty, so if you think there is a problem you can give the folks at Generac a call, toll free, at (888) 436-3722 x5381 or the Generac Service Locator to find the Authorized Service locations closest to you.

At Least One Lemon In The Batch
It took several phone calls and 2.5 weeks to get the warranty parts I requested - an inlet screen and a bolt for the oil drain. I finally got the washer fired up, and then the engine wouldn't shut off.

I spent an hour on the phone with Generac before one of their technical people suggested that I pull the boot off the spark plug.
I am now in the process of trying to send it back, and have been told it takes 10-15 days to get me the proper forms shipped out to me so that I can ship this... more

Generac One-wash
So far very satisfied, works as advertised. Have used to clean car, RV and concrete.

Delivery was spot-on with no problems at all, used the same day for the first two functions mentioned above.

Will look at Power Equipment Direct for other needs as they arise.
Pros: Easy To Use, Features, Price, Easy To Store
Cons: Nothing Yet And Don't Expect Any

Full Adjustability Is Great
I've used it three times.

I washed highly solid concrete, moss growing on brick porch, three cars and some vinyl siding. It did a great job on all surfaces. Having full adjustability is great.

I had one small problem at shut down. The On / Off switch did not shut washer down. I found two wires off on the back of the switch.

Nicer Than I Thought
This pressure washer kicks a@#. The only thing I would do is add a foot peg for starting because the unit is lightweight (which is a good thing) and easy to pull across the driveway to start.
Pros: Price, Light Weight, Quiet, I'd Buy It Again
Cons: Needs A Foot Peg For Starting

Very Good Machine
It started on the second pull, & runs for about 2.5 hours on one tank of fuel. The variable pressure dial makes it very useful for other things around the house, like car washing without destroying your paint- but you can still use it to quickly clean concrete on the highest setting.

Buy this unit- it is awesome!

Negatives- oil is a little hard to put in. Start cord harder to pull than expected. Have to use a funnel to put in gas and oil. Pump is close to the line where the wheels... more
