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?

I have a Husky pressure washer with a Honda 2600psi engine. Problem is, no water will come from the pressure hose. I connected the water w/out the pressure hose and water flows thru strongly. I then connected the pressure hose w/out the wand and water flowed thru the hose fine. When I connect the wand and pull the trigger, nothing. I have replaced the wand and that was not the problem. Please help.


Check the quick disconnect to the wand these are spring operated and can get stuck ... 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.

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.
