Plumbing – Causes of a Leak on the Supply Side of a Washing Machine Hose

I have recently installed a new washing machine. In the new machine, as well as for the old one, there is a leak as indicated in the following picture:

What could cause this? I have screwed the clamp tightly by hand – should I be using a tool to do this?

Note: this is on the cold side, and the hoses are new, but the faucets old.

Make sure there is a washer in there. Compare it to the hot water side for the washer.

These fittings always say "hand tighten ". I have seen very few that tighten sufficiently by hand, especially when dealing with head pressure. Take your pliers or Channelocks and give the nut an eighth of a turn further than your "hand tight".
