I have a Karcher 3.68 electric pressure washer. The motor does not seem to stop running and there is no high pressure. This leads me to believe that the unit is not building up the needed pressure. I took it apart and noticed water inside the greased thrusters and springs. This did not seem normal. Could bad seals be my pressure problem or does it sound like something completely different? I made sure all other parts were not obstructed and there did not seem to be any mineral build up that would block the water flow.
