Suggestion, if you don't want mold in the detergent drawer, don't use it. I have front loaders at home and fabric softener and detergent leaves a gummy residue that turns to mold.
So I buy Tide HE with Downy and pour it on top of the clothes. No more problems with mold.
I also occasionally run a cycle with just a cup of vinegar to clean everything out.
And don't forget to leave the door open afterwards so everything dries out.
