Hi Barry, Greetings from another fellow Ohio appliance collector. Your 1-18 set in poppy is just stunning, and with a window lid too! Yes, I have noticed that some 1-18's make the lights flicker, in the same 60cps type of flicker in conjunction with the JetCone going up and down. I had sold one years ago to a friend, and had to replace it with another washer after his many complaints of it making the lights flicker during the wash cycle. I think certain wiring installations are more sensitive to that than others. Actually, I kind of find it facinating!
