Usually electric pressure washers only have oil on the pump, so its very likely that you will find the problem there. I'd say check all the pump seals and if that doesnt solve the problem, you can check to see if all bolts are tight when you close the pump back.

Re: karcher pressure washer leaking oil
All 4 stroke engines have oil, and 2 stroke can have a oil mixer reservoir to mix with engine gas or to lube the chains , gears, pumps. If yours is 4 stroke as likely then the oil may be leaking at the seals to the main. (bad news) Pressure wash it (lol) and locate the leak, to speed up the leak you can pump some compressed air into the engine (be creative)

This is noticed on the Karcher washer and does not need any attention unless you are having a large spill over or leak. The oil oozes out when the pressure washer works for some time and is a result of a pressure leak when the washer is used for sometime.
I had seen this happen on mine for sometime , checked on all sides for any damage but there was none. So ignored but cleaned off the leak and was not seen then.
I have the same Problem, the leak is from the seam of the Manifold housing. There is a small crack in the seam. A manufacturing defect.. A New Manifold Complete Replacement K2.26*
Part # 97501760 is $61.03, 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.
unfortunately these little units have this problem commonly, 9 times out of 10 it will be the plastic head or the plastic valve block on the unit will be cracked and leaking slightly... it builds up pressure then leaks out and tries to build up the pressure again and this just reoccurs over and over...
you can get this repaired but is normally about half the cost of a new unit, if the pressure is still okay i would probably recommend just keep using it until it proper dies...
If you do get this fixed, we have studied into this and believe the main cause of heads cracking is warm water say if your inlet hose is in the sun for a period of time this can cause the water to become quite hot or if the unit sits and water trapped inside the head assy freezes can also cause this.
Hope this helps
Most likely your air filter is plugged or dirty, or the crank case vent valve needs to be cleaned.if it still does it check that the oil level is at the full mark, if overfilled it would cause the same problem.
The pump has a section with pistons that must have oil. The oil/piston housing is between the motor and the water portion of the pump. Some seals, somewhere are leaking. If you run it without oil it will destroy itself. You must get it fixed and I would do so before using it again.
hi. you will need to go inside the machine to have a look, but it might just be a micro switch on the bypass valve stuck.
you can not miss it, there is a wire going to it, just unclip and check with a meter when pressing the little switch in and out.
