I have a Kenmore Heavy Duty washer, model C110 4870880. It has started to leak what looks like oil from underneath. There are no corresponding sounds or smells, but for a little while now, the knob sticks at the second rinse point. If I move ithe knob slightly, the machine moves into that cycle, and sometimes (though I haven't noticed why) it doesn't stick.
Any and all help/siggestions GREATLY appreciated.
Thanks,
