Cold water connection

I was having some problems with the washer not draining properly so I pulled it out cleaned out the water drainage hose and figured while I had the heavy thing out I should clean the strainers on the cold and hot water inlet hoses. While trying to pull out the strainer I messed up the tip of the threads to the water connection on the back of the washer. I used a utility knife and metal file to take of the messed up tip and now seem to have a very small leak ( putting a paper towel around hose during a cycle it is slightly damp). What should I do now. Can the male connector on the back of the machine be re-placed?
