I have no water coming through the lance when powers on. When I first turned the pressure washer on some water trickleout of lance and then nothing.

Make sure that the detergent is turned off. Otherwise it will draw air instead of water.

A quick test if you have concerns about the detergent valve/regulator is to pinch the hose coming from the detergent bowl. That will stop it drawing air.

Otherwise I think you have a pump or pressure regulating valve issue.

Hi sounds like the pump has gone kaput. The motor will be working if you can hear a noise although the pump is at fault if the water pressure is same as out of the tap.
