This could be your unloader valve taking in account the engine isn't surging. Does the engine run smooth? Do you have at least 50 psi water pressure feeding the pump? Inlet screen clogged? ALL tips act same way or no change?

Check that your are getting proper water pressure. Also check filter going into the machine where the hose connects sounds like the washer is not getting enough water pressure.

My Karcher K9.8 electric pressure washer started


Not Simple.
I have the same Problem, the leak is from the seam of the Manifold or on the pressure side of the Pump and the hose housing. In my case there is a small crack in the seam of the Manifold Housing. A manufacturing defect.. A New Manifold Complete Replacement about the half the price what I paid for this pressure washer at Walmart... :( If under 1 year old, and you can find a receipt,Karcher will replace the whole Pressure washer under warranty.

Surges on and off when not in use


You must have a slight leak from somewhere like the trigger or hose etc. Any slight leak on the out pressure side will cause the machine to surge. If you don,t have any leaks then it will be a worn n/r valve on your pump.

The power washer is surging cuting in and out when i turn da nozzele to get stronger water pressure?


When I use my machine I hook up the water to the pump, hook up the high pressure line and gun, then turn on the water full and squeeze the triger to make sure all air is out before starting the pressure washer(mine is gasoline powered). Then I install the nozel on the spray gun. If you are having surgeing water pressure Check the hose washer where the water hose hooks to the machine, and be sure the supply hose is not restricted and valve is on full.
If this was helpful please leave Feedback. Thanks, SP

Karcher G 3000 BH Engine Pumping Problem


This may not be a motor problem. It sounds like your pump is not working properly and the motor is just following the pump. First thing to do is check for leaks in the pump, wand hose, gun etc. It may also be a blown water seal inside the pump.

When motor is at idle speed it surges


Try a simple test. It is ok to run the pump without water for a short time. Check idle speed without water in system to see if enginet surges. If it does not surge, then most likely the unloader/ pressure valve is causing the engine to surge when in the unloaded state. Life of unloader /pressure valve is shortened by letting system bypass for long periods of time. Enjoy

Not enough pressure


Speed regulation on small engines is notriously fussy.
Check the linkage to the carburetor and look for a small, light spring.
If there are several holes for one end of it, you may have to try more than one to find the spring tension that lets the engine run steadier than it now does.
If not, then either replacing it or changing the length by shortening or lengthening it will probably be needed.
