turn it off at the little nozzel" their should be a wing nut on the nozzel or little screw, ! when you have it off , see if the leak is comming from the mains side. if its the machine side if so get a vice grips and give it a little turn clockwise, then turn it back on , and see if the leak has stopptd , if not give it another turn .
