I have a Delta 3500 psi power washer that has maybe 20 hours use on it and it now won’t spray. Starts fine, but won’t “pressure” wash. Have been unable to find a place that repairs them or find parts on the web. Anyone know how to troubleshoot these or get them repaired?

Traditional lime wash still has tons of useful applications.

Have you got the chemical injector tube hooked up? Hose filters clean?
Sounds like the pump pistons have lost their seal. Some pumps are more susceptible to that than others. A good pump like a Cat is worth repairing. Others may need replacing.
Try the business to business yellerpages. Power washer sales and service. They're not cheep.
Will try the yellerpages, thanks. The chemical tube is not hooked up, but I'll check the filters. Hope it ain't the $$pump$$.
Did it freeze, mine did and it was done.
Look on the end of the pump for the pressure release valve. It will usually be a vertical valve with an adjusting nut on top. It comes apart pretty easy and only has a spring, a ball and a couple of O rings. If you don't use the pressure washer much the valve will stick inside the valve body and you won't have pressure.
