Right next to it on the list
A rank or two either side of the LG WM5800H*A: LG WKHC252H*A ($19/yr, 99 kWh/yr), then LG WM6998H*A ($19/yr, 99 kWh/yr).
Within the LG lineup

What this adds up to over time
NAHB's Study of Life Expectancy of Home Components puts a typical washing machine's service life at 10 years; run the LG WM5800H*A that long and it costs about $186 in electricity, on top of whatever it cost to buy.
Shopping for a new one
Efficient as certified washing machines go, $19/year is a reasonable baseline if you're comparing what else is on the market.
Worth comparing a few current certified models before deciding.
If you're keeping it
The LG WM5800H*A already costs $19/year to run; a repair bill on top of that is the kind of expense a protection plan exists to smooth out.
Where this number comes from
Nothing here is estimated from a nameplate wattage; the 99 kWh/yr is ENERGY STAR's own certified figure for this model. 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.
