I have a karcher K3.000 electric pressure washer and had to replace the head and the oil leaked out. What type of oil does it take, where to put the oil back and how much does it take? Thank you!

SOURCE: no high pressure no leaks motor runs off and on when trigger is released

check filter in wand and clean out nozzle hole for starters

Sounds like the pressure valve is broken thats why you cant depress the trigger , the valve is on the pump , i would suggest taking it to a repair shop as they are fiddly things to fix

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.

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.

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.
