Depending what set up you have just turn the throttle  to minimum hit the kill switch and most pressure washers will automatically dump the pressure in the hose through the unloaded valve , that’s how mine works anyway .

if yours isn’t like that turn the throttle to  minimum hit the kill switch and keep the trigger pulled on the Lance whilst the engine stops this will reduce the pressure from pump to the lance to nothing 

I have a GX390, I lower the revs down slowly, then switch it off.

Then operate the lance again which releases pressure from the hose and allows me to disconnect it.
