replacing dishwasher hose, which way do I turn this?
When dealing with anything threaded, the thing to remember is "Righty Tighty, Lefty Loosey"
If you want to remove the hose then you have to get a wrench on it and turn it to the left.
If you want to put the hose on and tighten in you have to turn it to the right.
If its a portable dishwasher you may be able to move it and tilt it in a position that allows you to have better access.
