The only thing that will kill the mold spores for good is bleach - you will have to add some bleach - read the direction on how much to the laundry - and if you do't do that then you will need to run a load of water through your machine with bleach to get that out of your machine as well. Mold is not something to play around with, as some molds are toxic. I would toss the entire mess in the garbage and forget about it. Not worth the potential harm. I work in a library and we have to know our mold. Bbrrr.....
