Question about Karcher 2500 PSI Pressure Washer
I have removed the piston and spread white lithium grease all over it and put back together and that did not work. I am connected to a garden house and assume that I have a high enough volume of water running through the system. The pressure washer is about 8 months old and the previous owner used it one time about 6 month ago. I started it up 3 days ago and used it for about 20 minutes. The pressure was intermittent then at first but then was constant and was running fine. I ran out of gas. I put new gas into it a couple days later and have had this problem every since. I used regular gas instead of premium....could be part of the problem.
Your pump is probably cavatating. when you first hook it up and turn hose on open thr trigger and let water run thru until it quits spitting and flows smooth. then crank it up and see if this gets it done. if not you could have a problem with the pressure valve bolted on the outside of pump. there should be a nut shaped stem to adjust pressure . turn it in and see what happens.
