Another option is that you nozzles are blocked. Get a pin or small needle and poke them in the tiny holes in the nozzles on the bonnet. Give it a good wiggle and move in and out and try again. If it improves, even slightly then it will probably be this still.
Another way is to disconnect the hose underneath the bonnet going to the nozzles.
