Cannot get pressure washer to give a stedy flow of water

Gas, electric, brand, model... all of this would help. Tell us what size hose you are running to the washer and how many psi you are supplying. What comes out when you squeeze the trigger?

Could a valve be stuck

Karchers have a screen just inside the connection where the garden hose connects. Remove the hose and reach inside with your little finger to drag out the screen and then flush it. Your unit may require the use of a 3/4" hose so check the manual.
