Question about Karcher 2500 PSI Pressure Washer
We have a Karcher Power Washer - Gas Unit - M # HD3101DR
Unit will not build up pressure to hose.
1- Clean all filters
2- Clean parts
3- Trying to find the Bypass for this unit. People have said bypass can be the problem, but where is it?
I had the same problem with my Karcher. The recall was lifted Aug. 0f 2007. Tried numerous people at Karcher....head of Customer Service, vice president, etc. No one returns telephone calls not even cutomer service....poor, very poor customer service. Thinking about calling Germany.

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.

Unloader valve is the problem, remove it and grease it with silicone grease
