Pressure washer won't start with water on.

Help! I have a Craftsman pressure washer model 580.752192.
I can start it fine when there is no water pressure but when I turn on the water I can't even pull the starter cord. Any help would be greatly appreciated!

New development: I started the washer and then turned on the water. It stayed running but I got no water out of the gun.

I always start my pressure washer with the water on and the trigger pulled on the gun. If I try to start it with water on and no trigger pulled, it will recoil on me bad. It hurts, ask me how I know...

That's exactly what happened. Then I started it first and turned on the water second and it stayed running but no water goes to the wand.

Run the water through the pump until you a steady stream, without air pockets.
Release the nozzle trigger and try to start. If it gets hard to pull, use the nozzle trigger to release the pump pressure and then try starting again.

When all else fails, read the instruction manual.

I've always run water thru the pump, hose and wand before starting - just a good practice to have! Remember the water is what cools the pump. I've also found it easier to start the PW with the trigger depressed.

I have a big Honda pressure washer. I know exactly about the recoil that will break your arm.

I have a water shutoff control screwed in at the pressure washer. I open the water valve and the wand valve and fill the system with water. I shutoff the water supply valve and then let go of the wand. Now I start the engine and immediately open the water supply valve.
