have k2400 HH works well until i release trigger then when trigger is pulled again no pressure. if i remove tip nozzle and pull trigger plenty of water comes out. then install nozzle and works fine until trigger is released. have to repeat removal of nozzle and works again any sugestions?

Pressure washers need back pressure in the washing lance to allow them to generate water force - it sounds like the nozzle itself is faulty.
