I deinstalled my old dishwasher as I getting a replacement. The supply line has been dripping ever since. I double checked the supply line was firmly closed and tightened the nut from the water supply to the dishwasher nut - but still leaking - help!!

    The valve probably has calcium buildup, sometimes opening and closing will clear it, not always tho.

Supply valve is not fully shutting off.

Consider replacing it.

If that is not a task you wish to do now get a plug for the line to temporarily stop the drip until new DW is installed
