Karcher G3025OH Pressure Washer - Answered Questions & Fixed issues
Karcher 3000 psi won't start.
It sounds more like a carb problem flooding and dumping some gas into the oil. This unit probably has a low oil sensor and the gas could be affecting this. I would have somebody look at the carb and find out why doing this, change the oil and try again. I have one that leaks gas because of float problems, that has done it since new, waiting for spring to remedy. Good luck, Also you can go to Karcher.com for a parts explosion and manual if needed.
Wont start acts like no spark but is getting spark
Did you try pulling the spark plug and spraying some starter fluid or carb cleaner into the cylinder, putting the spark plug back in and starting it? If you've got spark and it doesn't start for a few seconds then you probably have carb problems. Good luck!

It sounds like the carborator has a drain ****, with a hose attached so it doesn't get gas all over everything. The reason to do this is to drain condensate once in a while. See if you can find a small drain valve and check to see if it is closed. Then add some more gas and wash away!
Engine and water pressure surge
Almost certainly, your problem is being caused by the engine governor being set wrong. The governor is responsible for adjusting the engine as it comes under a load. With the breather off the carb, watch for the linkage that moves all by itself when you pull the trigger. It will have a spring as part of it, and an "arm" that is part of the linkage. This arm has 4-7 holes in it. Moving the spring to a different hole may fix the problem. There is also usually an adjustment screw that you can toy with and see if that tweaks it. But I'd definitely try moving the spring -- 1 position at a time -- and see if it a). helps or b). hinders......... Depending on the answer, you get a clue as to which direction to go with your next adjustment attempt. One of two directions will put the correct tension of the spring/arm and cause the governor to govern correctly.

Some soap injectors have an adjustment that must be turned to allow or increase the amount of soap that enters the line. To make it work, install the blace tip on the wand (black tip has a very large hole/nozzle). With the black tip installed there will be very little pressure in the discharge hose and soap will enter. If your machine does not have an adjustable injector you dont need to do anything for it to work. If soap does not enter, stop enging and turn off water. Remove the injector fitting and check for debris. There is uaually a spring and checkball (very simple design).
MY PUMP DELIVERS HARDLY ANY
There is a valve on the water pump called an unloader valve, when this valve sticks open it will not allow the pressure to build. This valve is designed to recirculate the water when you release the trigger so you don't damage the pump. Go to jackssmall engine repair.com and type in the model # of your unit and it will give you a parts breakdown so you can see where the unloader vale is located or if you have the manual for your unit look in that. Remove and clean. If this doesn't work you may have to replace it.
How do I get the
with most pressure washers, the soap is mixed before the pump. in order for this to work correctly you must use the black spray tip. It is much larger then the others and delivers the soap at a much lower pressure. put the soap tube in the soap solution and it will be drawn up and out the tip.
Pressure washer does not spray consistent flow of pressure
Pressure washers have a pressure regulator/unloader that bypasses the water back into the intake when you let go of the trigger with motor running. If you let the machine run for long preiods in bypass the system could be damaged due to heating of the water being bypassed. The water is in a closed loop. The as the unloader wears it will tend to want to bypass which is what is happening in your case. Dirt trapped at the tip will cause this also. Install clean tip to solve problem. If clean tip did not help then try lowering the pressure by turning pressure regulator counterclock wise. If problem is gone then parts are failing but keep using pump. Good luck.

It sounds like the fuel bowl is not filling quickly enough. Turn the fuel tap off. Then take the fuel bowl off the carby. You will see a plastic float. Above the float is a needle (small pin like) that should shut the fuel off & let it run also. Turn the fuel back on,the fuel should be running out quickly. Push the float up and the fuel should stop running. If no fuel is coming out then the needle is stuck. Clean with carby cleaner and push up & dowm a few times to ensure it is working OK. You may need to replace needle. Turn fuel off. Put fuel bowl back on and turn fuel tap on. Test.
No pressure on output.
dose water spray though the sprayer with the pump off if not there a small filter where the hose connects make sure its clean if there is no filter you may have scored the pistons
Fuel leaking at carb when
fisrt thing to check is that the fuel bowl is done up tight.
then check if the carby bolts are tight.
if fuel is still leaking check the needle & seat in the carby are shutting off properly.
if fuel is still leaking the gasket between the carby and motor need replacing
I try to pull the
IF YOU HAVE BEEN USING THE PRESSURE WASHER AND THEN TURNED IT OFF,THERE WILL STILL BE PRESSURE IN THE HOSE.YOU WILL NEED TO SQUEEZE THE TRIGGER ON THE GUN WHILE YOU START THE ENGINE.
Can not start the engine
Here is the long answer with everything we learned while using a power
washer twice a day for years::
It sounds like could be one of the problems listed below or a
combination of those things.
1) The exhaust is partially blocked. Check the screen covering exhaust
port for carbon and dirt build-up. High-speed exhaust air must pass
freely. We finally broke the exhaust screen out with a screwdriver to
get our machine going one day.
2) Gas is not flowing freely to carburetor > under gas tank, find the
rubber hose connected to carburetor. Pull off rubber hose and make sure
gas flows freely. You can use this hose to drain gas tank of old gas
... and then put in fresh gas.
3) Carburetor is partially gummed up and engine cuts off when gas flow
slows down. Buy some gum out, and then don't store power washer with
gasoline in the tank. Or put additive in gas when storing machine.
4) The choke is letting in too much gas or not enough gas. Try different
adjustments. The choke-lever on our power washer got so bad that we
could not set throttle at full open or the machine would die. We still
use the machine at 2/3 throttle, and then start it each time using WD-40
as described below.
5) Dirty air filter that won't let engine breath enough air to keep up
with combustion. Take off air filter and see if problem persists.
6) The spark coil is going bad?? Change spark plug to see if problem
persists. Is spark plug wire pushed all the way onto the spark plug?
Now the nitty gritty: we're gonna start that thing right now
7) Take off air filter. Spray WD-40 directly into carburetor. Yes, we
use WD-40 every time to start my power washer, and we use the washer
twice a week.
Spray in the WD-40, Pull the engine cord. The engine will
fire on WD-40. Guaranteed.
Once it starts, keep spraying WD-40 directly into carburetor to keep
engine going.
If engine will not fire and keep going on WD-40, then your spark is
suspect.
If your engine fires and runs on WD-40 but dies without it, then your
gas supply or carburetor are suspect
8) Carburetor problem >>> try Gum out >>> and then
take machine to small engine repair shop
9) Spark ... take out spark plug. Put spark wire back on. Hold spark
plug by spark wire. Touch metal threads of spark plug to metal opening
where plug came out. Metal to metal. Pull back start cord and look for
spark between the metal.
If you have no spark, then spark coil is bad
>>> take machine to small engine repair shop
