I have a 6.75 HP #580762200 pressure washer. It has no pressure. I took it apart to check for any broken parts. As far as the springs that the rods come down to the pump are working ok. They move up and down in their rotating as required. I took apart the spacer and water pump. I cleaned out every hole and checked for any blockage or broken parts and found none and blew out everything. Replaced any defective O rings and checked all springs. All the rubber and plastic seal are ok ( where the 3 rods come down threw ) are ok. After putting it back together and started motor there is no preesure other that what the hose is providing. I took off the spray gun hose and water comes out ok, then I started the motor with the spray gun hose still off and no pressure at all with motor running other than pressure from hose. What could be causing it not to build up any pressure ? What parts do you think would need replaced or is the pump just shot ?

Thank you Gary

I understand how diffcult it is when your equipment does not want to work properly. While you are waiting for your expert answer, I have found a link that will provide some infromation on the issue. It sounds like there is a part failure in the pump, but the only way to know for sure is to dissamble it and inspected the parts individually. I hope this helps.
