You probably have figured out your problem by now, however, just in case you are still dealing with this problem, here is how I solved mine: the hose filter screen, located in the cold water hose on the end attached to the washer, probably needs to be cleaned out! That's what I did with mine and it works with no leaking now.

Just so I wouldn't have to pull the washer all the way out from the wall in the future, I put a hose filter in the cold water hose on the end attached to the faucet. Keep those filters clean and the leaking will end! Bob N
