SOURCE: Ryobi 3000 psi pressure washer detergent injector

Most detergent injectors work by the venturi system. That is that the detergent is drawn into the stream by the forward flow of the water thru a very narrow port after the water passes thru the pump. This system works best when the pressure at the tip of the wand is low. Trying using a very large tip to draw in and apply the detergent, then remove injector and rinse with high pressure. Not good for the pump but to apply soap reliably under high pressure the soap needs to be injected through the intake of the pump. enjoy

SOURCE: pressure washer, john deere 3000 psi, honda engine

Pressure variance is caused by the unloader/pressure regulator valve or slipping belt on belt drive systems. Worn packings in the unloader will not maintain pressure. Try lowering the pressure to 1000 psi then slowly increase until problem reveals then lower pressure again to maintain steady stream. This problem can also develop if the wrong size tip is used in the gun. Example, if output rating is 3000 psi at 4.5 gal per min and you are using a tip for 3000 psi at 4 gpm. The unloader will release causing variance of pressure. Easy way to lower pressure of system is to increase the size of the tip to 5 or 5.5 gpm in a system rated at 4.5 gpm. Enjoy

SOURCE: cannot get it to uptake the bleach for spraying

On most pressure washers you wont be able to draw soap/bleach into pump unless you are spraying on low pressure.There is a valve on the inside of inlet hose fitting that closes when high back pressure is sensed.Would it draw bleach into hose when wand tip is removed?

I have the exact same pressure washer and have had the same issues with it. The cure for me was to simply run the washer with the gas cap loose. For some reason the fuel gets vacuume locked and stops flowing into the carb. The fuller the tank is it seems the shorter the time is between the time it starts and the time it shuts off. Or you might find a way to vent the cap. Hope this helps.

My unit will start to pulsate/surge then completely shut off.


Possible that there is dirt accumulation on the pressure washer.
1.check if the lines are clogged?
2. Check the gun open and blow air.
3. check the power switch .
4. check line to motor and if safety/load switch is acting due to overload caused by accumulation of dirt.
So clean up and check again.

Northstar PW shuts off hot if washer is moved. Honda engine


Being petrol driven, it may have a mercury kill switch which puts a ground on the ignition circuit stopping the engine if you move it. Perhaps for safety in case you overturn the unit somehow.

John Deere will replace the cap for free; they acknowledge the vendor who supplied Briggs & Stratton gas caps provided faulty caps. Call 1-888-228-3068 then 1 (English), 2, 1 and a technician will ask you for model number and Serial Number (which they need to replace the cap). Don't drill a hole in your cap: debris will find a way into the gas tank and end up possibly fouling the engine. Bob from NJ
