When I release the spray trigger on my Sears Gasoline Pressure Washer to change positions it will not start spraying again. Is this "pressure Lock"? How do I correct it so it will spray again? The motor continues to run. This morning it worked fine. I changed nothing, but this afternoon it started fine, but "locked up" the first time I released the trigger.

Hi,
Got a model number so I can look up the type of pump used?
Peace,
Clarke

Have you tried running it
1. without a hose
2. with hose but no trigger gun

It sounds more like the trigger gun is merely gone bad, how old is the gun.
