What sits beside it in the ranking
Samsung WF45T60**A* ($17/yr, 90 kWh/yr) costs a little more to run than the LG WM3275C*. LG WM3270C* ($17/yr, 90 kWh/yr) costs a little less.
Comparing LG's own models
LG makes 93 ENERGY STAR certified washing machines; this one ranks 6 of 93 for running cost, between the brand's cheapest, the WM3420C* at $15/yr, and its priciest, the WT7485C* at $41/yr.
Cost over its typical lifespan
NAHB's Study of Life Expectancy of Home Components puts a typical washing machine's service life at 10 years; run the LG WM3275C* that long and it costs about $169 in electricity, on top of whatever it cost to buy.
Is it worth replacing?
The LG WM3275C* is already efficient for its category at $17/year. If you're shopping and comparing options, this is roughly what a well-chosen new washing machine costs to run.
Worth comparing a few current certified models before deciding.
Protecting what you have
At $17/year just to run, a washing machine is worth protecting against an unplanned repair bill on top of that.
Sourcing
Two sourced numbers, nothing modeled: ENERGY STAR's certified kWh/yr for this exact model, and EIA's published state electricity rate. The full Washing Machine category page shows all 398 washing machines ranked by cost; the state-rate guide covers the half of this number that isn't the appliance.
