What this adds up to over time
NAHB's Study of Life Expectancy of Home Components puts a typical dishwasher's service life at 9 years; run the Smeg DW8601 that long and it costs about $396 in electricity, on top of whatever it cost to buy.
Shopping for a new one
The Smeg DW8601 is already efficient for its category at $44/year. If you're shopping and comparing options, this is roughly what a well-chosen new dishwasher costs to run.
Worth comparing a few current certified models before deciding.
Protecting what you have
A dishwasher like the Smeg DW8601 is a real household expense whether or not it needs replacing yet; a protection plan is one way to budget for a repair rather than a full replacement.
