Turns out this machine was made in September 1987 at Whirlpool's Findlay, OH facility (which I believe still operates today). It was installed probably a month or so thereafter by my late dad and late uncle. I remember being there when it was installed (I was in high school). 31 years, a good run! . Within a month or so, I will be getting the new machine and hopefully installing it shortly thereafter.Good photos!
How old is your house you have this dishwasher in? What year was your house built?
