Grease or oil is getting into the wash water, I think from somewhere by the agitator?
Answer Hello Gary,
This is a highly unlikely situation. I have seen in over twenty years of appliance repair, the vent hole on the transmission stopped up and when the transmission oil heated up it expanded the oil into the washtub. Most of the time when this complaint arises it is due to a build-up of fabric softener under the agitator. When the fabric softener is put into the dispenser, it is supposed to be diluted with an equal amount of hot water. This disolves the softener so it will not cling to surfaces and causing an issue. You see, fabric softener is made of 80 to 90% animal fat. The remaining content is coloring and perfumes to mask the softeners' decomposition. I'm sure at some point you have cooked bacon and had grease pop out onto the countertop. As you know, you cannot simply wipe it up. You have to use something to cut the grease to get it up. This is the same thing that happens with the fabric softener. It will build up under the agitator and it will actually change color as it ages. By the time it is yellow or brown, a chunck will break free and get into the wash. This, being animal fat based, will stain the clothes and look just like grease or oil.
