SOURCE: Karcher Power Washer Problem
I had same problem won't build pressure. go to http://www.wmpcs.com/index.php?main_page=page&id=14 and see diagram. I pulled white plastic cover off top of pump (2 torx screws), remove main pump from gas motor otherwise you wont be able to get at the valve below. The important part is the valve below the the white plastic piece, it has a raised slot and mine was stuck in there. I used needle nose pinched together with pliers to lift it straight up. After wd40 and cleaning the hole and valve it should pop in and out easy. Put everything back mine worked like a charm after that. So at least I know what the problem is. Great powerwasher-I use for house painting part time and love it.

I have the same problem. With mine I have to remove the tip that I am using then pull the trigger and then replace the tip and pull and pressure should return. I believe that one of my valves is sticking causing me to reprime the pump frequently. I am trying to clean or replace my valves to fix the problem.
I hope this helps.

if its just a plug, remove it with an allen key and wrap a couple layers of teflon tape around it. That should stop, or at least slow down any leaks that are coming out of the threads.
