What sits beside it in the ranking

Within the LG lineup
LG makes 38 ENERGY STAR certified dishwashers; this one ranks 14 of 38 for running cost, between the brand's cheapest, the LDNFC33L at $41/yr, and its priciest, the SDWD24 at $45/yr.
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 LG LDNTM545 that long and it costs about $372 in electricity, on top of whatever it cost to buy.
Is it worth replacing?
The LG LDNTM545 is already efficient for its category at $41/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
At $41/year just to run, a dishwasher is worth protecting against an unplanned repair bill on top of that.
