My power washer is not generating high pressure. It starts

Customer Question

My power washer is not generating high pressure. It starts and runs fine, engine sounds good, but the water just comes out with only slightly more power than my hose.
Any suggestions? I looked in all the connections for dirt or clogging, but didn't see anything.

Welcome to JUST ANSWER small engines, let me try to help you !! Your spill/unloader valve is stuck and not letting pressure build. Get the parts list for the pump and locate the valve, on the inlet side of the pump, remove it and clean and lube it. The re-install and it should work.

unloader valve may need to be replaced.

How can I tell? Can I test it?If it's not closing, shouldn't I feel some water or air coming out of the hole?
Expert:  Curtis B. replied 1 year ago.
No way to test it. It has to move back and forth to let pressure build and release.

You could have other problem, when did it last work?
Expert:  Curtis B. replied 1 year ago.
Could it have frozen over the winter?
Customer: replied 1 year ago.
It's possible that it froze up over the winter, last time I used it was last summer. The spring appears to be in good condition and the power washer is only about 2-3 years old.
Expert:  Curtis B. replied 1 year ago.
If unit froze, it will have internal damage. In that case, you would not want to repair, but replace?
