Can a washing machine leak oil into the drum during its cycle?
yes it can. We had this happen and the washer was junked as a result. It seems that the washer is built around the “spin bearing”. This bearing sits in the middle of the washer shaft and is what the washer spins on. If it starts to wear out, it can leak grease from the bearing and stain clothes. Our repair man told us that for the cost of repair, we would be better off buying a new one.
