I have a fairly new Karcher 2300 PSI gasoline powered pressure washer I purchased from COSTCO. Almost immediately out of the box I noticed i would have to hold the trigger on the wand in for 30 seconds or more before pressurized water started coming out. Now I need to hold it for
2 - 3 minutes and if I am lucky I'll get pressurized water! Any ideas?? Thanks!- posted
