Our new dishwasher says, right there in the operator’s manual, to push the start button twice to wash the dishes using the settings from the previous cycle. Push the button once and tiny lights identify the earlier settings. Once understood, this is very nice, even for those of us without previous experience in twice-pushing dishwasher start buttons.
New appliances come with other surprises that, when the human habit factor is added, may mean those vaunted energy savings are less than the government assures.
We got the new dishwasher, to start, because we had the money. Then I saw an ad about a Sears Memorial Day weekend sale.
