Can anyone see the water level settings on the washer? I haven't tried to expand that part of the picture, but there is a lot of glare above the level knob on the left.
This machine is a 1983 model, either a 23721 (70 series) if it has three levels, a 23741 (also a 70 series) if it has five levels but I don't see the markings for five on the panel, or a 23801, which is an 80-series, which would have an infinite level switch. If the machine had a white basket --- doesn't look like it does, its pretty dark around the agitator --- it would be a 23821, the $10 extra 80-series for the two coat basket.
The dryer is a 1976 or 1978 model. I've never used one of those dryers with the "set it and forget it" main dials. They sound very easy to use and appreciate.
