We have the lg direct drive machine. Lately I've noticed a really sour smell when doing laundry. I don't use the drawer but cleaned it & wiped around the seal & set it to tub clean function. No difference,pulled the door seal a bit & omg there was thick sludge. It made me gag. Cleaned that all off,cannot begin to explain how gross it was! No difference. Cleaned filter etc,put on boil wash. No difference. Pulled seal back again to see fine green black layer of scum. Really hard to get to but I have given it a go. Filled it with laundry bleach & napisan & put on a medic wash. Hoping that will loosen it so I can get the layer off.
Wish me luck. My life is beyond glamorous!
