A few weeks ago, I installed a dishwasher, and used a floodsafe braided steel water supply hose from home depot. Hand tightened + 1/4 turn on both ends. The dishwasher side is dry, the fitting attached to the supply leaks. I bought a new hose, re-attached it, same story. I tightened a bit more than 1/4 turn close to 1/2 turn, and it still leaks just a but. a drip every 5 to 10 seconds or so.. Any advice. I didn't want to over tighten.

The shut off valve on the supply is brand new, so the threads look really clean and nice...
