Got a Kenmore washer, probably going on 20 years old, works fine. But it has developed an annoying glitch: after the wash cycle is over, it doesn't turn off completely. There's a *faint* buzzing sound that persists (solenoid energized???) until you push in the timer dial to shut it off. Nothing runs, no motor, no water flowing, just a quiet humming sound.
Anyone familiar enough with these beasts to suggest remedies? Squirt some contact cleaner in there somewhere?
