Question and Answers

Q:

what can cause my pressure washer (580762200 ) not to build up any pressure ?

A:

Thank you for your question.

I am sorry you are having a problem with the pressure washer. Usually the problem is a stuck unloader valve. The unloader valve opens when the handle is not pulled to keep the pump from building to much pressure. If the unloader does not close when the handle is pulled, it will not build pressure. I recommend checking the unloader first. I have marked the unloader in the image below. Remove the unloader and inspect the parts. You can clean the parts with WD-40.The spring is stout and hard to push but make sure the parts move freely. If the pump will not build pressure after cleaning, I suspect the pump is the problem.

If you do not feel confident repairing this problem yourself, then you can have it repaired by a Sears technician. Here is a link that will provide the nearest drop-off locations: Sears Home Services .
