Report "I really appreciate the help and the information I have read so far. My Karcher K2400HH runs like heck until you release the trigger. Then, if I take the quick-connect nozzle off, pull the trigger and shoot a stream of water, I can then put the nozzle back on and it runs like heck again UNTIL I release the trigger. Then, it is the same process each time I release the trigger. Kind of frustrating"
