Re: Will start and run fine water comes out but has no...
Maybe bad pump. Remove wand and wand hose, run machine with water in. High pressure water coming out of wand/hose connection, bad wand or hose. No high pressure water, bad pump, replace.

The water admittance valve is stuck. The spring loaded valve lets more water into the pump when the pressure drops when you trigger the wand. Take the valve apart, clean the bore with crocus cloth on a dowel rod. Replace the O Rings and lube with plumber's grease and reassemble. Good as new! The O rings get dry, deposits build up in the bore, and the spool valve sticks at the high pressure end so no further water comes in to be pumped. Half hour job, get an O Ring kit to refurbish.
Pressure washers have a pressure regulator/unloader that bypasses the water back into the intake when you let go of the trigger with motor running. If you let the machine run for long preiods in bypass the system could be damaged due to heating of the water being bypassed. The water is in a closed loop. The as the unloader wears it will tend to want to bypass which is what is happening in your case. Dirt trapped at the tip will cause this also. Install clean tip to solve problem. If clean tip did not help then try lowering the pressure by turning pressure regulator counterclock wise. If problem is gone then parts are failing but keep using pump. Good luck.
your not missing anything, check the pump, they tend to go bad over time and may need replacing. The pump provides the pressure as well as the suction for the whole process, pulling water from the hose or tank and pushing it forcefully through the pressure washer line. If the motor is running and you have the water going through the line and to the pump, and no water is coming out, my guess would be the pump.
Check first that no debris is blocking the holes in the spray arm where the water comes out, and clean out the holes.
In case it will not solve your problem, it's look like a pump problem (the pump has two functions : drive water to the spray arms and to drain water out the washer).
Open the rear panel and listen if the pump works during the wash cycle. In case it doesn't work, it should be replaced.
Good luck !
