Pump on Karcher power washer not increasing pressure engine works fine


... Karcher Pressure Washers

I have a model PW 2200 gas pressure washer. It suddenly lost it's high pressure the other day after working fine for @10 minutes. It's getting plenty of water, but the engine doesn't seem to rev up to give it the high pressure. The operating instructions say to check the oil in the engine, and the PUMP before starting, but I haven't found any place to check for an oil level in the pump????Any ideas, I'm very confused.

Troy-Bilt 2550 20293 pressure washer not producing pressure. Worked when last used 2 months ago. Pump pistons are moving up and down when engine is pulled through. Inlet water is flowing through pump but no pressure when engine is started. I have the same problem. Water flows thru the pump when not running, but no flow or goes in by-pass mode when I start the pump. The pump being Troy Bilt Model 020296-01. I replaced unloader valve even. Anything else I can do?


You replaced the unloaded valve. Are you positive you have the unloader screwed to pressure and not turned the opposite way? You will have no pressure if it is adjusted wrong. One other thing I have encountered is that the unloader has a ball bearing ... Pressure Washers

My Troy Bilt power washer (using Honda GCV160 engine) has no pressure coming from the pump. I checked the water flow, everything seems fine. I believe the pump needs oil added, however, I can't seem to firgure it out (how to add oil to the pump). I did notice that previously, I used to see drops of oil coming from under the pump. I I have a bad seal, can I add oil and test the pressure before I change the seal? Please advise.
