Falling KitchenAid Water
Originally, Fallingwater did not have a dishwasher since it was built before WWII and domestic staff were plentiful. The house was closed during the war years due to a shortage of heating oil and gasoline. The parents spent those winters in the California desert and Fallingwater was generally not used during January and February anyway. After the war, the elder Mr. Kaufmann's health was beginning to fail, household staff were finding jobs in other fields and Mrs. Kaufmann had to devote more time to taking care of her husband. This led to the installation of the KitchenAid dishwasher. After she died in 1952 and Mr. Kaufmann remarried in 1954, the AGA was replaced with the electric stove so that it would be easier for his new wife to do some cooking which she enjoyed. As far as I have been able to find out, automatic laundry equipment was not installed in the laundry room by the garage. On wash day, clothes lines were strung in what is supposedly America's first carport so that the laundry could dry outside while remaining unseen from the house.
